Journal articles on the topic 'SAT reasoning test'

124 freshmen entering engineering were administered the College Major Interest Indicator, Adjective Checklist (personality), Ship Destination Test (symbolic reasoning), and the Logical Reasoning test (verbal reasoning) to identify what combination of variables would best predict the first semester's GPA. Scores on these tests along with SAT-Verbal and Mathematics scores were used in a series of multiple regression analyses. Personality test scores alone were the best predictors of GPA ( r = .78).

AbstractAbstract solvers are a method to formally analyze algorithms that have been profitably used for describing, comparing and composing solving techniques in various fields such as Propositional Satisfiability (SAT), Quantified SAT, Satisfiability Modulo Theories, Answer Set Programming (ASP), and Constraint ASP.In this paper, we design, implement and test novel abstract solutions for cautious reasoning tasks in ASP. We show how to improve the current abstract solvers for cautious reasoning in ASP with new techniques borrowed from backbone computation in SAT, in order to design new solving algorithms. By doing so, we also formally show that the algorithms for solving cautious reasoning tasks in ASP are strongly related to those for computing backbones of Boolean formulas. We implement some of the new solutions in the ASP solver wasp and show that their performance are comparable to state-of-the-art solutions on the benchmark problems from the past ASP Competitions.

The SAT (Scholastic Aptitude Test) has become a part of our culture, a constant measure, a rite of passage. It has served its purpose well - to assist in the prediction of academic performance during the freshman year of college. During the 1993-94 school year, however, the College Board will change the SAT by introducing the SAT I: Reasoning Tests, the SAT II: Subject Tests, and the Preliminary SAT/National Merit Scholarship Qualifying Test. This array of assessment instruments, builds on the heritage of its predecessors, but also makes some new departures. This presentation looks at the context and process which informed decisions to change the tests, describes those changes and what they will mean, and then looks ahead to the future.

AbstractSeveral hundred thousand intellectually talented 12-to 13-year-olds have been tested nationwide over the past 16 years with the mathematics and verbal sections of the Scholastic Aptitude Test (SAT). Although no sex differences in verbal ability have been found, there have been consistent sex differences favoring males in mathematical reasoning ability, as measured by the mathematics section of the SAT (SAT-M). These differences are most pronounced at the highest levels of mathematical reasoning, they are stable over time, and they are observed in other countries as well. The sex difference in mathematical reasoning ability can predict subsequent sex differences in achievement in mathematics and science and is therefore of practical importance. To date a primarily environmental explanation for the difference in ability has not received support from the numerous studies conducted over many years by the staff of Study of Mathematically Precocious Youth (SMPY) and others. We have studied some of the classical environmental hypotheses: attitudes toward mathematics, perceived usefulness of mathematics, confidence, expectations/ encouragement from parents and others, sex-typing, and differential course-taking. In addition, several physiological correlates of extremely high mathematical reasoning ability have been identified (left-handedness, allergies, myopia, and perhaps bilateral representation of cognitive functions and prenatal hormonal exposure). It is therefore proposed that the sex difference in SAT-M scores among intellectually talented students, which may be related to greater male variability, results from both environmental and biological factors.

The Social Attribution Task-Multiple Choice (SAT-MC) uses a 64-second video of geometric shapes set in motion to portray themes of social relatedness and intentions. Considered a test of “Theory of Mind,” the SAT-MC assesses implicit social attribution formation while reducing verbal and basic cognitive demands required of other common measures. We present a comparability analysis of the SAT-MC and the new SAT-MC-II, an alternate form created for repeat testing, in a university sample (n=92). Score distributions and patterns of association with external validation measures were nearly identical between the two forms, with convergent and discriminant validity supported by association with affect recognition ability and lack of association with basic visual reasoning. Internal consistency of the SAT-MC-II was superior (alpha = .81) to the SAT-MC (alpha = .56). Results support the use of SAT-MC and new SAT-MC-II as equivalent test forms. Demonstrating relatively higher association to social cognitive than basic cognitive abilities, the SAT-MC may provide enhanced sensitivity as an outcome measure of social cognitive intervention trials.

We conducted two studies to replicate and extend, as well as test, the limits of previous findings regarding an apparent disconnect between scientific-reasoning skills in psychological science, on the one hand, and scores on standardized tests of general intelligence, on the other. In Study 1, we examined whether this disconnect would extend beyond psychological science to additional sciences as well, such as nutrition and agriculture. The results did indeed extend, suggesting that scientific reasoning across various natural sciences is comparable to scientific reasoning in psychological science, but different in kind from the reasoning required on conventional standardized tests. In Study 2, we examined whether these findings were linked to the format of presentation of scientific problems. Whereas real scientific-reasoning problems are open-ended, standardized tests tend to use multiple-choice format. We discovered that using multiple-choice format did indeed result in an apparently closer relation of the scientific-reasoning tests to two of the conventional ability measures (SAT Reading and Number Series) but not to two other tests (Letter Sets and SAT Math). Thus, one can increase the correlations of scientific-reasoning tests with at least some standardized ability tests but at the cost of content validity and ecological validity.

The main objective of the present pilot study was to construct and standardize a Scientific Aptitude Test (SAT) for the secondary school science students (Grade 9 and 10). The test items (30 questions) were prepared by the researchers based on the five important aspects in scientific thinking such as Analogy, Scientific reasoning, Numerical ability, Logical reasoning and Comprehension based questions. A test of multiple choice items were used as a data collection instrument in the six different schools in the selected districts in Tamilnadu, India. The computer based Microsoft excel spreadsheet (2007) was prepared to document the obtained score and the same used for statistical analysis. Through recent method of item analysis, Cronbach’s Alpha values were computed using IBM SPSS software. The reliability coefficients were found 0.874(Spearman-Brown) and 0.672(Guttmann Split-Half). Hence, the present pilot study revealed that the scientific aptitude test for secondary students to ignite their scientific temper and also useful in preparing future competitive examinations.Int. J.

The results of the PISA in 2018 where Indonesia take place 72th of 79th country. One of the factors is the learning that has not pay attention to aspects of students' mathematical reasoning abilities. RME approach is emphasize on creative thought process and involves student’s reasoning abilities.This research aims to determine the influence of the Indonesia’s Realistic Mathematics Education approach on mathematical reasoning abilities students grade V on geometry lesson. The type of this research is one group pretest posttest design. The population consisted of 86 student who sat in class IV, V and VI then selected 12 children from class V as a sample that was given treatment with the RME approach. Technique to collect data using tests, interview, and questionnaires.The results of data analysis showed that students' mathematical reasoning increased from a pretest score 64 increased at posttest to 80. Then using analyze of paired sample t-test with ? = 0.05 obtained tcount = 7.881 > ttable = 2.201 so that H0 is rejected and Ha is accepted. Then it can be concluded that the Indonesia’s Realistic Mathematics Education approach is influence to the mathematical reasoning abilities of students grade V on geometry lesson.

This study aims to examine the effect of compensation schemes, self efficacy and moral reasoning on slack budgeting. In this study the hypothesis is proposed that in the slack inducing compensation scheme the slack budgeting will be greater than using the truth inducing compensation scheme, then managers with low self efficacy will do slack budgeting compared to those with high self efficacy. It is also proposed that the individual with low moral reasoning will do slack budgeting rather than the individual with high moral reasoning. The research design in this study was a quasi 2 x 2 laboratory experiment, with Accounting students who had sat in the 5th semester of Padang State University as lower level managers who participated in budgeting. The statistical method used to test the hypothesis is two-way ANOVA. This study provides results that the compensation scheme can affect slack budgeting actions, self efficacy has no effect on slack budgeting actions, and the interaction between slack inducing compensation schemes with low self efficacy has no effect on slack budgeting actions. Moral reasoning affects slack budgeting actions, and at lower level managers who have low levels of moral reasoning and low levels of self efficacy, interactions with slack inducing compensation schemes affect slack budgeting actions. The results of this study can contribute in the management accounting literature related to budgetary slack and its causal factors.

In the last two decades, modal and description logics have been applied to numerous areas of computer science, including knowledge representation, formal verification, database theory, distributed computing and, more recently, semantic web and ontologies. For this reason, the problem of automated reasoning in modal and description logics has been thoroughly investigated. In particular, many approaches have been proposed for efficiently handling the satisfiability of the core normal modal logic K(m), and of its notational variant, the description logic ALC. Although simple in structure, K(m)/ALC is computationally very hard to reason on, its satisfiability being PSPACE-complete. In this paper we start exploring the idea of performing automated reasoning tasks in modal and description logics by encoding them into SAT, so that to be handled by state-of-the-art SAT tools; as with most previous approaches, we begin our investigation from the satisfiability in K(m). We propose an efficient encoding, and we test it on an extensive set of benchmarks, comparing the approach with the main state-of-the-art tools available. Although the encoding is necessarily worst-case exponential, from our experiments we notice that, in practice, this approach can handle most or all the problems which are at the reach of the other approaches, with performances which are comparable with, or even better than, those of the current state-of-the-art tools.

In many nations, grades and standardized test scores are used to select students for programs of scientific study. We suggest that the skills that these assessments measure are related to success in science, but only peripherally in comparison with two other skills, scientific creativity and recognition of scientific impact. In three studies, we investigated the roles of scientific creativity and recognition of scientific impact on scientific thinking. The three studies described here together involved 219 students at a selective university in the Northeast U.S. Participants received assessments of scientific creativity and recognition of scientific impact as well as a variety of previously used assessments measuring scientific reasoning (generating alternative hypotheses, generating experiments, drawing conclusions) and the fluid aspect of general intelligence (letter sets, number series). They also provided scores from either or both of two college-admissions tests—the SAT and the ACT—as well as demographic information. Our goal was to determine whether the new tests of scientific impact and scientific creativity correlated and factored with the tests of scientific reasoning, fluid intelligence, both, or neither. We found that our new measures tapped into aspects of scientific reasoning as we previously have studied it, although the factorial composition of the test on recognition of scientific impact is less clear than that of the test of scientific creativity. We also found that participants rated high-impact studies as more scientifically rigorous and practically useful than low-impact studies, but also generally as less creative, probably because their titles/abstracts were seemingly less novel for our participants. Replicated findings across studies included the correlation of Letter Sets with Number Series (both measures of fluid intelligence) and the correlation of Scientific Creativity with Scientific Reasoning.

Rauscher, Shaw, and Ky in 1993 found that listening to a Mozart sonata temporarily enhanced performance on the spatial reasoning task from the Stanford-Binet scale. The present study was designed to replicate those results using the Revised Minnesota Paper Form Board Test. 30 women and 21 men were randomly assigned to one of two conditions. In one condition, subjects listened to a Mozart sonata for 10 min., while in the control condition subjects meditated in silence for 10 min. Immediately following these manipulations all subjects worked on the spatial task, the Revised Minnesota Paper Form Board Test, for 10 minutes. After factoring out SAT scores and gender, there was no significant difference in the mean test scores for the two groups. The results are discussed in terms of Gustafsson's 1984 factor analysis of intellectual abilities in which he identified three separate visuospatial factors. The task used here may have had a substantially different factor loading than the dependent variable used by Rauscher and associates.

ObjectiveTo determine whether scores on two undergraduate admissions tests (BioMedical Admissions Test (BMAT) and University Clinical Aptitude Test (UCAT)) predict performance on the postgraduate Membership of the Royal Colleges of Physicians (MRCP) examination, including the clinical examination Practical Assessment of Clinical Examination Skills (PACES).DesignNational cohort study.SettingDoctors who graduated medical school between 2006 and 2018.Participants3045 doctors who had sat BMAT, UCAT and the MRCP.Primary outcome measuresPassing each section of the MRCP at the first attempt, including the clinical assessment PACES.ResultsSeveral BMAT and UCAT subtest scores displayed incremental predictive validity for performance on the first two (written) parts of the MRCP. Only aptitude and skills on BMAT (OR 1.34, 1.08 to 1.67, p=0.01) and verbal reasoning on UCAT (OR 1.34, 1.04 to 1.71, p=0.02) incrementally predicted passing PACES at the first attempt.ConclusionsOur results imply that the abilities assessed by aptitude and skills and verbal reasoning may be the most important cognitive attributes, of those routinely assessed at selection, for predicting future clinical performance. Selectors may wish to consider placing particular weight on scales assessing these attributes if they wish to select applicants likely to become more competent clinicians. These results are potentially relevant in an international context too, since many admission tests used globally, such as the Medical College Admission Test, assess similar abilities.

The study developed, validated, and standardised a statistical literacy test for university undergraduates in Cross River State, Nigeria. Five research questions were raised to guide this study. The study adopted an instrumentation design. A stratified sampling technique was used to select a total of 753 respondents from a population of 4705 students. Three instruments were used to collect data: the Statistical Literacy Test (SLT), the Statistical Reasoning Test (SRT), and the Statistical Anxiety Test (SAT). Descriptive statistics (means and simple percentages), correlational analysis, and the factor analytical technique were used to analyse the data collected. The result showed that only 25 items survived the last item assessment. The instrument was found to have strong construct validity as the items in the correlation matrix were all positively correlated. The statistical literacy scale showed convergence with statistical reasoning but diverged with statistical anxiety. The reliability of the instrument was found to be high as the coefficients of the scale were 0.81, 0.77, and 0.78 respectively, and it was adjudged reliable. Based on the findings of the study, it was concluded that the instrument was valid and reliable. Thus, it was recommended that students' skills in statistics should not just be on the computational aspect but on the utilisation of statistical knowledge. Statistics lecturers should emphasise statistical literacy to help students reason and think statistically, and the instrument should be widely distributed for use by researchers and psychometricians.

This study proposes a typology of abilities tested by university entrance examinations with types of knowledge (experiential versus academic) and objective (instrumental versus value) as indices. Four types of abilities are extracted: generic, communal, nomothetic, and political. The proposed typology is examined by past questions on literature subject exams in four countries. The analysis reveals that the sat in the United States measures effective reasoning for versatile application, whereas the National Center Test in Japan examines the ability to infer human emotions for the creation of inner-community. The Iranian konkur tests the understanding of universal laws for guiding principle in life and French baccalauréat tests the mastery of dialectical procedure for innovation. Entrance examinations reveal the types of abilities and attitude each society values. The proposed typology aids in understanding their qualitative differences, which past studies were unable to elucidate.

The goal of this research is an examination of the degree of development of hypothetical-deductive reasoning in general high schools (?gymnasiums?) in the Republic of Serbia. Hypothetical-deductive reasoning is one of the categories of scientific reasoning that can be measured by the Lawson test. The main characteristic of this reasoning is the indication of the degree of development of abstract thinking in adolescents. Adolescents who have developed this method of reasoning can "operate" statements, establish complex relationships among them, and combine them in a systematic way by reaching a set of all possible combinations. Hypothetical-deductive reasoning is especially important during experiments in physics teaching. It is therefore important to examine how many students have reached this level of reasoning, and find a way to increase the level of scientific reasoning of students. The research involved 654 high school students from Novi Sad and Backa Palanka. The results of the study showed that around 13% of gymnasiums answered correctly all questions related to hypothetical-deductive reasoning. The obtained data indicate that for most students, hypothetical-deductive reasoning has not been developed. The paper presents the way in which hypothetical-deductive reasoning can be developed or stimulated.

Numerous researchers emphasized the connection between mathematics and physics, as well as the pupil's lack of linking knowledge gained within these subjects. In this paper, examples of the connection between mathematics and physics will be examined by the scientific reasoning test and the initial test created for this research. In the research related to the initial knowledge and scientific research, 235 students of the first and second grade of gymnasiums in Novi Sad and Backa Palanka participated. The results of the research have shown that most of the students did not correctly answer questions related to reasoning based on proportions. The obtained result points to the pupil's misunderstanding of the notion of the smallest interval of an instrument, that is, the value of an instrumental error, which is the basis of the correct reading of the experimental results in the teaching of physics. From the point of view of physics, it is important for pupils to point out the mistakes they have made in concluding, in order to correct their claims and the exact information associated with existing ones in longterm memory.

sebab ia menjadi faktor yang menentukan kelangsungan hidup suatu bangsa. Suatu bangsa akan mengalami kehancuran jika masyarakatnya mengalami penyakit moral yang akut. Oleh sebab itu, pendidikan moral atau akhlak kepada peserta didik menjadi suatu keharusan dan saat ini telah menjadi program inti pendidikan di hampir semua negara. Tetapi efektivitas pembelajaran moral sering dipertanyakan disebabkan banyaknya penyimpangan moral peserta didik, seperti perilaku curang, mabuk-mabukan, tawuran, pergaulan bebas dan sebagainya. Penelitian ini bermaksud mengujicobakan model pembelajaran akhlak berbasis teori kognitif dalam meningkatkan penalaran moral peserta didik. Sengaja dipilih domain penalaran sebab ia memiliki kontribusi terhadap tindakan moral seseorang, atau dengan kata lain penalaran moral seseorang mempengaruhi tindakan moralnya. Semakin tinggi penalaran moral seseorang, semakin tinggi pula tindakan moralnya. Penelitian ini dilaksanakan secara kuantitatif dengan metode eksperimen dan menggunakan rancangan one group pre-post test design. Hasil penelitian menunjukkan adanya perbedaan yang signifikan penalaran moral siswa sebelum dan sesudah eksperimen yang dibuktikan dengan nilai p < 0,05. Dengan demikian dapat disimpulkan bahwa model pembelajaran akhlak berbasis kognitif memiliki pengaruh nyata terhadap peningkatan penalaran moral peserta didik.

Abstract. It has been hypothesized that the evolution of animals during the Ediacaran–Cambrian transition stimulated the burial of phosphorus in marine sediments. This assumption is centrally based on data compilations from marine sediments deposited under oxic and anoxic bottom waters. Since anoxia excludes the presence of infauna and sediment reworking, the observed differences in P burial are assumed to be driven by the presence of bioturbators. This reasoning however ignores the potentially confounding impact of bottom-water oxygenation on phosphorus burial. Here, our goal is to test the idea that bioturbation increases the burial of organic and inorganic phosphorus (Porg and Pinorg, respectively) while accounting for bottom-water oxygenation. We present solid-phase phosphorus speciation data from salt marsh ponds with and without bioturbation (Blakeney salt marsh, Norfolk, UK). In both cases, the pond sediments are exposed to oxygenated bottom waters, and so the only difference is the presence or absence of bioturbating macrofauna. Our data reveal that the rate of Porg and Pinorg burial are indistinguishable between bioturbated and non-bioturbated sediments. A large terrestrial fraction of organic matter and higher sedimentation velocity than generally found in marine sediments (0.3 ± 0.1 cm yr−1) may partially impact these results. However, the absence of a clear effect of bioturbation on total P burial puts into question the presumed importance of bioturbation for phosphorus burial.

Penalaran induktif adalah cara menarik kesimpulan yang bersifat umum dari kasus-kasus yang bersifat individual. Berpikir nalar matematis adalah salah satu kemampuan utama yang perlu dimiliki dan merupakan fitrah manusia. Melalui berpikir nalar manusia terus berkembang dan meningkatkan kemampuan dalam beradaptasi dengan lingkungan yang dinamis dan berubah secara kontinu serta dapat berkreasi dan menciptakan teknologi yang dapat mempermudah kehidupannya. Berdasarkan wawancara langsung yang telah dilakukan kepada Guru Matematika SMPS YKPP Sungai Pakning, mengungkapkan bahwa masih banyak peserta didik yang masih kurang baik dalam kemampuan berpikir induktif, dan jika kemampuan ini tidak dilatih, maka akan mempengaruhi perkembangan anak dan nilai akademiknya terutama di bidang matematika.

The paper analyzes the comparative effectiveness of Computer-Assisted Learning (CAL) and the traditional teaching method in biology on primary school pupils. A stratified random sample consisted of 214 pupils from two primary schools in Novi Sad. The pupils in the experimental group learned the biology content (Chordate) using CAL, whereas the pupils in the control group learned the same content using traditional teaching. The research design was the pretest-posttest equivalent groups design. All instruments (the pretest, the posttest and the retest) contained the questions belonging to three different cognitive domains: knowing, applying, and reasoning. Arithmetic mean, standard deviation, and standard error were analyzed using the software package SPSS 14.0, and t-test was used in order to establish the difference between the same statistical indicators. The analysis of results of the post?test and the retest showed that the pupils from the CAL group achieved significantly higher quantity and quality of knowledge in all three cognitive domains than the pupils from the traditional group. The results accomplished by the pupils from the CAL group suggest that individual CAL should be more present in biology teaching in primary schools, with the aim of raising the quality of biology education in pupils.

<p>Salah satu penyebab dari lamanya waktu tempuh mahsiswa di Jurusan Informatika UPN “Veteran” Jawa Timur adalah sullitnya memantau kemajuan studi mahasiswa secara seksama, mengingat jumlah mahasiswa yang cukup banyak serta pihak akademik belum memiliki metode yang akurat untuk memetakan mahasiswa yang diprediksi akan mengalami keterlambatan dalam penyelesaian studinya. Melalui perkembangan teknologi informasi yang berkembang pesat saat ini, maka sangat dimungkinkan untuk membuat sebuah sistem yang mampu memprediksi kemungkinan keterlambatan kelulusan mahasiswa melalui penggunaan berbagai metode komputasi yang ada. Salah satu pendekatan yang dapat digunakan untuk membuat sebuah sistem prediksi kelulusan adalah menggunakan pendekatan populer yang digunakan dalam pembuatan sistem cerdas <em>(intelligent system) </em>yaitu <em>case based reasoning </em>(CBR). Langkah-langkah yang dilakukan pada penelitian ini adalah melakukan pengumpulan dan memasukkan data kasus pada basis kasus, melakukan praprosesing yakni normalisasi atribut yang akan digunakan dalam perhitungan similartitas antar kasus menggunakan normalisasi min-max, implementasi CBR menggunakan metode Euclidean Distance, serta melakukan pengujian pada 141 data kasus. Dari sisi perhitungan akurasi, sistem mampu memberikan nilai akurasi paling tinggi sebesar 100% pada pada pengujian berdasarkan predikat kelulusan, sedangkan berdasarkan ketepatan waktu, sistem mampu memberikan akurasi tertinggi dengan nilai 85,71%, dan sistem mampu memberikan nilai akurasi tertinggi sebesar 71,43% pada pengujian berdasarkan massa studi. Untuk pengujian presisi, sistem mampu mengasilkan nilai terbesar berturut-turut sebesar 90,90%, 43,33%, dan 100%. Sedangkan pada pengujian sensitivitas, sistem berturut-turut mampu menghasilan nilai sebesar 90,90%, 40,48%, dan 100%. Hasil pengujian ini tentunya sangat bergantung dari basis kasus yang dimiliki, oleh sebab itu perbaikan dan peningkatan jumlah kasus yang dimiliki diharapkan mampu meningkatkan performa sistem rekomendasi.</p><p> </p><p><strong><em>Abstract</em></strong></p><p class="Judul2"><em>One of the reasons for the length of study time for students of the Informatics study program of UPN "Veteran" </em><em>Jawa Timur</em><em> is the difficulty of monitoring the progressy, given the large number of students and academics do not have an accurate method to map students who are predicted to experience delays. </em><em>I</em><em>t is possible to create a system that is able to predict the possibility of student graduation delay through the use of various existing computational methods.

The study aims to identify the role of self-confidence, meta-cognition, personality traits, and motivation (predictive variables) as factors of success in second language (L2) learning. It is assumed that there is a high correlation between the observed variables in the meta-cognitive process, which distinguishes academically gifted students from regular students, and that self-confidence is an autonomous factor of success and has a significant role in the self-regulated motivation of gifted students. The results on the Language Proficiency Test are a criterion variable, while gender, residence in the country of the native speaker, duration of L2 learning, and average grade in studies are moderator variables. The sample is convenient, and consists of 460 students from the University of Novi Sad and the University of Belgrade. The research was carried out using a quantitative approach and a method of systematic non-experimental observation. The following instruments are used: the Big Five Personality Traits Questionnaire, the Meta-cognitive Awareness Inventory, the Memory and Reasoning Competence Inventory, the English Language Motivation Questionnaire, the Rosenberg Self-esteem Scale, and the L2 Proficiency Test. The main findings confirmed the hypothesis of a high correlation between the observed variables in the meta-cognitive process that distinguishes academically gifted students from regular students, as well as that self-confidence is an autonomous factor of success and plays an important role in the self-regulated motivation of the gifted. This confirms the significance of self-confidence in self-regulation and provides an indirect role in L2 learning achievements. Students should be aware of meta-cognitive processes and try to self-regulate their knowledge and learning strategies.

Kata Kunci: penalaran analogi, kemampuan matematika, persamaan logaritma Abstract This research is a qualitative descriptive study which aims to describe the analogical reasoning of high school students in solving logarithmic equations based on mathematical abilities. The subjects of this study were three students from class X Mathematics and Natural Sciences at a high school in Sidoarjo who have high math ability, medium math ability, and low math ability, are female, and communicative. The instruments of this study were mathematics ability test questions, mathematical analogy reasoning test questions and interview guides. The result of this research is that at the encoding stage, students with high, medium, and low math abilities can correctly explain the information and what is being asked in the source questions and the target questions. At the inferring stage, students with high, medium, and low mathematical abilities are able to determine and explain the concepts used in working on the source and target questions, but when identifying the linkage of information between the source question and the target question only students with high and moderate mathematical abilities are able to find it, while students with low math abilities are unable to find the relationship. At the mapping stage students with high and moderate mathematical abilities can determine linkages and explain the similarity of concepts between the source questions and the target questions, while students with low math abilities are unable to explain the linkages and similarities of concepts between the source questions and the target questions. At the application stage, students with high mathematical abilities can work on the target problem correctly, students with mathematical ability are not doing the target question correctly because they do not change the example that has been made into logarithmic form, while low-ability students even though they cannot mention the relationship between the source question and the target question she can answer the target questions correctly, this is because the student only follows the procedures she has learned before.

Supplemental Instruction (SI) has been a successful implementation into institutions worldwide. It serves as a means of reducing attrition and increasing the overall learning of course material. The City College of New York (CCNY) has recently implemented SI to General Chemistry I courses to examine whether or not SI would help students succeed in the course and understand and grasp the course material better. SI was made available several times a week during flexible times to students who are struggling in the course. Our method of data collection is a Likert-type and open-ended questionnaire that was distributed at the end of each of the semesters to SI participants in an anonymous fashion. Furthermore, we compared the grades and performance of students participating in SI with those who did not. The collected data enabled us to examine the impact of implementing Supplemental Instruction (SI) in General Chemistry I at CCNY. Our data show that SI was beneficial, contributed to improving students’ understanding of course material, and increased their success rate. About 80 percent of students who failed the first exam and participated in SI obtained a passing grade compared to 11 percent of those who did not.Keywords: supplemental instruction, chemistry education research, student learningINTRODUCTION Supplemental instruction is derived from the term developmental education and stems from a branch of Learning Assistance Centers or LACS [1]. To better understand the origins of Supplemental Instruction, we must first understand the framework that set up this type of education. Developmental education originates in the 1600s and focuses mainly on the assumption that each student has multifaceted talents that can be developed academically, opposed to focusing on the deficits of a student [1]. The main goal was to naturally adapt the students’ population to higher education through means of social and academic domains allowing the students to grow in multiple dimensions in their academic skills [1].Developmental education later paved the way for academic programs such as Learning Assistance Centers (LACs). It was viewed as an extension of the classroom and did not discriminate between faculty and students, and within the student population did not discriminate between students who performed to standard and those who performed below par. LACs were for everyone who wanted to be academically enriched [1]. As a new program, LACs had six main objectives: “higher course grades for participating students; central location for students to receive tutorial assistance; a referral source to other helping agencies; a comprehensive library of basic study aids; a training agency for paraprofessionals, peer counselors, and tutors; and a center for faculty development.” [1]. These goals made it very clear that this service was not to be mislabeled as remedial, which was a main topic of interest when it comes to implementing new services, like this one, in schools. LACs are essentially a tool used to attain higher education, not provide a remedial course. Another important reason as to why LACs were adopted into other higher education institutions is to increase student retention [1]. LACs jump-started improved learning across campuses not only in the United States but across the world.In the 1990’s developmental or remedial courses were not allowed to be offered at public four-year universities, thus making supplemental instruction a very attractive candidate to solving the issue with students’ academic integrity and attrition [1]. College faculty members were drawn to SI due to its minute fiscal commitment and that it strongly promoted individual self-learning for the students, this meant less time spent teaching for instructors [1].SI or supplemental instruction is as it states - supplemental instruction offered to the students enrolled in a course. SI gives the students the opportunity to work in a cooperative setting on problems and is supported by peer instructors [2]. SI works to increase academic performance and retention but utilizing both collaborative studying in addition to independent studying and analysis of study strategies. SI sessions are offered for traditionally difficult high risk course; ‘historically difficult’ courses are also identified by analyzing the grade distribution of courses throughout each academic division, “courses in which 30% or more of the students receive D or F grades or withdraw, become targets” [3]. One of the main factors that attribute to the individuality of SI programs is that it focuses on historically difficult courses [4] and large classes where students have little opportunity for interaction with the professor or other students [5]. Labeling a course as historically difficult allows you to categorize the class as challenging without placing blame on the professor or the students.SI sessions are scheduled on a weekly basis and all students enrolled in the course are encouraged to join. SI sessions act as a continuation of the lesson learned during in-class lecture with the instructor. Being that SI sessions are not tied down to class time, students can attend whenever and however many times they wish without the restriction of a required course preventing them. Constant feedback will be given based on the student’s grasp of the material taught in class, thus giving them ample time and motivation to alter their study methods to adapt, if need be. Research on SI suggests that problem-solving skills and study strategies learned in SI courses are transferable to other courses which leads to improved performance [6]. Supplemental instruction sessions are typically led by an SI leader, who would be a former student that succeeded in the same course, however it is not uncommon for a professor to join an SI session for a course. SI may improve students’ retention and graduation because it offers the students the opportunity to network socially which speeds up the acclimatization to the college experience [7].SI provides a way to combine “how do I teach myself this” with “what do I need to know”. While SI helps students gain a more thorough understanding of the material, it also helps students to condition themselves and alters their thinking to accommodate for the type of information they are processing. SI differs from a remedial tutoring course because it is created based on the course versus the students [1]. This potentially makes attending SI sessions more attractive to students who are afraid or shy to ask for help.SI is not a remedial course, it is considered a mediator connecting the gap between the new information presented to students and the students current knowledge and practices, “SI bridges the gap between the current knowledge base and the acquisition of new knowledge by focusing on the refinement of the learning skills indispensable for acquiring new knowledge” [8]. Successfully implemented SI programs were able to track those students who attended and the impact it made towards their grade, for data that was collected institutionally [9]. SI can be effectively used to develop study skills, increase motivation and improve performance in participants [10].According to Wolfe, “…there appear to be benefits of SI in courses where students are being newly introduced to chemical concepts and methods, but these benefits seem to drop off when students are more experienced with the material.” [5]. The results further go on to conclude that SI is most beneficial to entry level science courses such as, General Chemistry I and Organic Chemistry I. It seems as though SI is a great addition into institutions to overall help attrition rates and more generally help students improve within their courses. More research has been done to give us a wider range of knowledge on SI within Chemistry courses [9]. SI can be used to address the continuous decline of fundamental chemical knowledge noticed in recent college graduates [11].In large lecture classes, there is a disconnect between the lecturer and the student. Supplemental Instruction (SI) is often offered in a more intimate setting where the SI instructors can have one-on-one time with students to individually hone in on their specific problems, whether it is conceptual or problem-solving. As for learning environment, SI is usually held in a smaller more accommodating room where it is a less intimidating more inviting space. This setting provides a social interaction component in which usual Chemistry lectures don’t provide. In addition to the more personal tutoring time available, students are also encouraged to interact in a common social setting. This allows for an opportunity of collaborative learning and may help foster a sense of community [12].The attraction to SI in a college setting is due to its short and long-term effects. The short-term effects of SI sessions are to instill a deeper understanding of the coursework within students. Whereas the long-term goals are two-fold, the academic goal is to change the way students learn, study, and understand information so that the knowledge stays with them. Students who participate in SI earn higher grades not only the course but in subsequent semesters, which is due to improved study habits and is considered a long-term positive outcome of SI [13]. The second long-term goal is to develop better social interaction skills within these students.Many public institutions have implemented SI and thus have uncovered several significant findings. Findings that were previously mentioned pertaining to the outcomes of SI includes achieving higher percentages of passing grades [1, 14]. Some studies also found higher graduation rates among participants [1]. Despite their better performance, SI takers often score lower on academic success predictors such as the SAT and ACT exams [14]; increases in performance, therefore, appear to not occur because stronger students use SI. SI helps promote problem-solving skills because it involves the learner in the construction of knowledge and information processing based on their prior experiences which could contribute to cognitive development [15-16]. Furthermore, SI has been shown to improve motivation and enhance study habits and understanding difficult concepts [17]. Participants in SI have been found to have better control on their achievement, self-esteem, and confidence [18]. SI has also been found to higher academic self-efficacy and grades [19]. Studies have reported that students who participated in SI in introductory courses in Biology or Chemistry courses tended to continue onto upper level courses in the field; SI has a positive effect on students’ enrollment in upper level courses [20-21]. We should note that Rabitoy and co-authors reported that SI enhanced students’ achievement in STEM fields and this was greater for females and students of color [22]. METHODS While researching the topic of SI as a whole, we were able to uncover many studies that were in favor of this new implementation in institutions. Our research study is unique because it targets only at risk students and provides an added value to the curriculum. SI was implemented into The City College of New York (CCNY) as a test run in the Department of Chemistry and Biochemistry. The CCNY is an urban minority serving institute that offers a diverse selection of classes, which vary from the arts to the sciences and everything in between. We wanted to try implementing SI into the sciences to see if at risk science students can benefit from it. Grasping the S in stem, our main goal is to use the successful methods of SI to see what benefits it can bring to general science courses.Beginning during the Spring semester of 2018, SI was implemented at The CCNY’s General Chemistry I course which is composed of lecture, lab, and Peer-Led Team Learning (PLTL) workshop. PLTL is implemented as an integrated part of the course [23]. In the General Chemistry course, after exam one was distributed and grades were given back, an announcement was made introducing SI. The lecture professor would encourage students who received a failing grade, classified as a grade below a 65 out of 100 on exam one, to attend SI as means of improving in the course. This makes our study unique since we are only targeting students who are struggling the course and are not likely to earn a passing grade. It is noteworthy that PLTL offers a collaborative learning experience for all students. SI instructors targeted weaknesses in study habits, socialization, conceptual-understanding, and problem-solving skills.SI was made available for five days a week and on those days, SI was scheduled around classes times which makes it easier for students with busy schedules involving work and class to attend. During SI sessions there are instructors that have been hand-picked by instructors from a cohort of recitation leaders and who have successfully completed the course and have received a grade of A in the course. SI attendance was not mandatory.Throughout the first session available after the Supplemental Instruction announcement was made to the lecture class, those who chose to attend, because SI was not mandatory and it was strongly recommended for struggling students. Students brought their first exam with them to be discussed. This initial discussion is a one-on-one between the student and instructor, which serves as a more social component to learning whereas that isn’t available during class time. The first exam was then discussed so that the instructor can now sift through the student’s strengths and weaknesses to later target them in the weeks to come. The overall composition of our Supplementary Instruction sessions was influenced by the previous studies done and researched, hand-picking methods that seemed to work and leaving off ones that were less successful. SI sessions included cooperative learning activities, and addressed students’ misconceptions and difficulties, explored difficult concepts in depth, and enhanced problem-solving skills [24].Every week during Supplementary Instruction sessions students were encouraged to come back to further work through their weaknesses. During this trial specifically, it was noticed by the SI instructors that a lot of students actually struggle with basic problem-solving skills and reasoning. To help combat this, worksheets were made each week based on the lecture topics covered in class, based on problem-solving to help build their skills. Aside from doing the worksheets, students were encouraged to bring in topics or questions they have on the material so the SI instructors can further clarify and explain. Furthermore, students came to SI with questions that they were struggling with. Students provided questions for the SI instructor to explain which created a mutually beneficial relationship [11, 25].Our research question is: How does Supplemental Instruction in General Chemistry I impact students’ learning, conceptual understanding, retention, and attitudes?In order to properly assess how beneficial SI is to the way students learn Chemistry, data were collected at the end of the Spring and Fall of 2018 semesters, as well as Spring 2019. We used a combination Likert-type and open-ended questionnaire, as well as, grade comparisons. The Likert-type section included a five-point scale, where (1) Strongly Disagree, (2) Disagree, (3) Neutral, (4) Agree, (5) Strongly Agree. For each question, the average was taken which helps make sense of the data. For the open ended questions, questions 1 through 3, we created and used a rubric to score the questions on a scale from 1 to 5 similar to what was mentioned above. For question 4, we compiled the answers and created pie charts based on the type and number of responses.As previously stated, at the end of the semester surveys were printed and distributed to each SI session. Students that attended SI were all encouraged to participate in this survey. A total of 44 out of 60 students were available and willing to participate in the optional survey.RESULT AND DISCUSSION Graphical depictions of each Likert-type question along with average responses are shown in Figure 1. FIGURE 1. Averages for the answers for each of the Likert-type questionnaire. Our data clearly shows that students overall had a positive learning experience with SI. The students agree that SI improved their basic problem-solving skills, understanding of concepts covered, and attaining a better grade in the course. Furthermore, SI participation encouraged students to practice problems and tackle their weaknesses in the course. SI participants believe that the SI instructors targeted their weak areas and helped them improve. Finally, students felt that SI was worth the time and effort they put into it and that it was beneficial and contributed to improvements in grades.FIGURE 2. Averages of the short-answer responses were numerically scaled using a rubric.Figure 2 shows that students overall had a positive learning experience with SI and that it helped them better understand the concepts. Furthermore, the participants would enthusiastically would recommend SI to other Chemistry students.FIGURE 3. The pie chart above shows the beneficial components of SI to studentsFigure 3 shows the parts of SI that students found beneficial. Overall, there were many useful features of the SI program that facilitated students’ learning and succeeding in the course. The students appreciated the time spent on problem-solving, the flexibility of the offerings – refers to the times and days, the individualized learning experience, and the one-on-one support, guidance, and tutoring. From the Likert-type questions given in part one of the survey, responses were broken down for each given question in order to visualize the impact of SI for the students/participants. The average of the responses can be seen above and was about 4.8. The corresponding results can be viewed above as shown in Figure 1. To turn our attention to Figure 1 ‘SI has helped me to improve my basic problem solving skills’, upon meeting with the SI instructor team at The CCNY we were made aware that students have trouble with basic problem-solving which leads to the disconnect in understanding how to build upon this knowledge. When students lack this basic skill, it is difficult for them to move on and build upon this skill as the course progresses, which ultimately leads to their failure to meet the level of understanding for each lecture exam. From the responses, we can see that majority of the students feel as though their problem solving skills have developed as a result of participating in SI. Questions 6-8 deal with an overall belief about the experience of SI participation. Based on Figure 1, SI helped students better understand the course material, and had an overall positive response as 100% of students felt like they did have a better understanding of the course material after attending SI. Students overwhelmingly agree that SI is very beneficial to the way they learn Chemistry. Our data show that SI is well received by the participants which is consistent with other researchers [11]. Short answer questions 1-3 were made in order to have a more in-depth understanding of the student experience with SI this past semester. These questions were formed as short answer so students were more inclined to share their opinions of SI. The collected data shows that the students strongly agree that SI has been very beneficial for ways unique to each student. Some students enjoyed the SI instructors and their way of teaching and helping the students understand the material. While others enjoyed how personal the experience was. It wasn’t a ‘one size fits all’ experience but an experience that was personalized to each student’s needs, strengths, and weaknesses. Short answers for question 4 also had very personalized responses. Question 4 in particular – ‘What features of SI did you find to be most beneficial to you?’ was very helpful in understanding what students appreciate most about SI, and served as a standard to which should be upheld. Responses ranged from the flexible times SI was offered to the small class setting which is extremely different than the lecture, and more comfortable. Students also enjoyed and benefited from the one-on-one attention they received in SI session. For that reason, students would make time to attend the SI section of their ‘favorite instructor’. Furthermore, the individualized learning experience was appealing to SI participants. The overall goal is to get each student to understand complex concepts and if one instructor can better help someone to reach this goal; SI is a success. The overall responses show that SI is very beneficial and contributed a great deal to the way that students learn Chemistry. One main issue we have encountered during this initial phase of implementation is low number of students who self-select to participate in SI. Only about 10 percent of students who failed the first exam, participated in SI. One reason could be that students might not buy into the philosophy of SI. A second reason might be that students do not think that SI would help them better understand the content and succeed on the course. A third reason could be due to lack of motivation in these students. Another reason could be attributed to the lack of maturity in students who are taking General Chemistry I. We use the term ‘lack of maturity’ loosely in this sense to mean the lack of knowledge of how to conduct oneself in a college setting [26]. Most commonly, freshman students come straight from high school where they have not yet acquired good study techniques or methods which work best for them. These reasons combined with the hardship required to understand such complex concepts that they’re learning for the very first time can deter students. Our data show that students who participated in SI after failing the first exam achieved a success rate of about 80%. Students who failed the first exam and did not participate in SI had an 11% chance of passing the course. This data is consistent with several research in the field indicating that students who participate in SI have a higher chance of successfully completing the course with a passing grade [14, 27]. We feel these data make powerful statement for the added value of SI in General Chemistry courses and its impact on students learning and attitudes.CONCLUSION In conclusion, our research study on SI provided valuable data into students’ learning and conceptual understanding of content in General Chemistry. Furthermore, our findings provide insights into students’ attitudes about SI implementation and its benefits to the participants. Our research data supports the introduction of SI into General Chemistry courses and provides students with learning skills, socialization competencies, problem-solving skills, and the knowledge required to successfully complete the course. We believe that our data supports the notion that SI had a significantly affected the participants grades in a positive manner and it should be noted that that majority of SI participants earned a passing grade in the course. Our results and data on the implementation of SI in General Chemistry courses improved students’ attitudes towards the subject matter, learning, socialization, and study habits. We are confident we can reach a larger population and improve our recruitment so more students can experience SI and increase their chances of successful completion of the course. As an implication for curriculum, we would recommend supplemental instruction for all introductory courses STEM fields. ACKNOWLEDGMENT We also would like to thank the Department of Psychology at the CCNY and CUNY Coordinated Undergraduate Education (CUE) for funding our Supplemental Instruction program.

Objectives: Virtual patient simulation (VPS) is used in the education of health care professionals. This method brings an opportunity for the learner to examine necessary diagnostic and therapeutic skills. The aim of this study was to assess the efficacy of VPS on clinical reasoning abilities of medical students and to evaluate their attitude towards VPS in clinical endocrinology course in a teacher centered educational environment. Methods: Fifty-one medical students in their 6th academic year were simply randomized in two groups, the simulation and the control. The students in the simulation group were provided by an application which presented them virtual case scenarios on diagnosis and management of thyroid nodules and osteomalacia. All the students sat for a diagnostic test at the beginning and at the end of the course. The test comprised a series of essay questions matched for their academic level and closely related to the case scenarios. They were also asked to complete a questionnaire to assess their attitude towards the application. Results: Participants in both groups did not have any statistical differences in scientific background in basic sciences (P=0.672) and prior clinical examinations (P=0.376). At completion of the course the mean score of the students in the simulation group improved significantly compared to the students in the control group by 3.5 vs. 1.0 points (P=0.001). The students found the application worthful and showed a positive attitude towards it. Conclusions: Virtual patient simulation improved clinical reasoning abilities of medical students in the context of a traditional teaching/learning environment.

AbstractWith the rapid development and large-scale uptake of the Internet of Things, smart home is evolving from a vision towards a realistically viable solution for assisted living. Activity recognition is one of the fundamental tasks in order to provide accurate and timely assistance and service. As daily living scenarios are full of similar activities, missing data, and noise, inferring complex activities using knowledge-driven reasoning algorithms suffers from several drawbacks, e.g., real-time raw sensor data segmentation, poor generalization, higher computational complexity, and scalability. To address these problems, this paper proposes a hybrid approach to complex daily activity recognition by merging the first-order logic and probability graphic modeling. Specifically, we develop a novel “Markov logic network” combining data-driven multi-feature and simplified rule-based modeling and inference, thus enabling and supporting the applicability and robustness of daily activity recognition. To evaluate the approach and associated methods, we design a testing scenario with a number of similar activity groups, missing data, or disturbance test datasets in a multi-modeling sensor scene. Initial results show our approach outperforms the traditional approach with a better accuracy in the situations of similar activities with missing data and noise disturbance. Experiments are also conducted to compare the Gibbs sampling and MC-SAT sampling algorithms for Markov logic network, and the results show that the Gibbs is better in our experimental settings.
