Tomando como ponto de partida o fato de que atividades matemáticas são descritas em livros didáticos, documentos oficiais e artigos acadêmicos por uma gama variada de adjetivos e que não há consenso acerca do significado destes, este artigo tem o objetivo de analisar como professores de matemática descrevem atividades para a sala de aula. Trata-se da replicação de uma pesquisa conduzida com professores de matemática britânicos. Nossos dados foram coletados via questionário eletrônico, no qual professores avaliaram o quão bem 88 adjetivos e expressões descreviam uma atividade matemática escolhida por eles. Esses dados foram analisados por meio de uma análise fatorial exploratória que identificou sete fatores independentes subjacentes aos dados. São eles: Efetividade, Rotina, Exigência, Abstração, Contextualização, Inovação e Interação. Além de uma discussão sobre cada um dos fatores, também são discutidas as semelhanças e diferenças em relação aos resultados obtidos na pesquisa britânica. Espera-se que este resultado ajude a informar o diálogo entre as várias partes envolvidas no ensino de matemática. Além disso, também se discute a relação identificada entre a expressão “resolução de problemas” e o fator Contextualização. Contrariando o que é sugerido em documentos oficiais, nossa análise indica que os professores de matemática no Brasil associam “resolução de problemas” com questões relacionadas a contextos reais e aplicados em detrimento de contextos matemáticos abstratos. Independentemente do motivo por trás dessa associação, este resultado aponta para a necessidade de melhora da comunicação entre políticas públicas e professores de matemática.Palavras-chave: Atividades Matemáticas. Adjetivos. Análise Fatorial. Resolução de Problemas. Contextualização.AbstractConsidering that mathematical tasks are described in textbooks, official documents and academic articles using a huge variety of adjectives and that there is no consensus around their meanings, this paper analyses how mathematics teachers describe such tasks. In order to do so, we replicated a study conducted with British mathematics teachers. The data was collected through online questionnaires in which teachers graded in a Likert scale how well 88 adjectives and expressions were fit as a description of a mathematical task chosen by them. The data were analysed using exploratory factor analysis and we identified seven independent factors, namely: Efetividade, Rotina, Exigência, Abstração, Contextualização, Inovação and Interação. Besides a discussion of each factor, we also discuss the similarities and differences between ours and the British results. It is expected that this result can inform the dialogue in the field of mathematics teaching and learning. Furthermore, we discuss in this paper a relationship between the expression problem-solving and the factor Contextualization. Differently to what is suggested in official documents, our analysis indicate that Brazilian mathematics teachers are associating problem solving with contextualized, applied, real life questions to a larger extent than with abstract, mathematical contexts. Aside the reasons behind this association, this result points to the need of improving the communication between policy makers and mathematics teachers.Keywords: Mathematical Tasks. Adjectives. Factor Analysis. Problem-Solving. Context-Based.

Mathematical anxiety is considered as one of the psychological obstacles that shall be considered by every mathematics teacher. Symptoms that felt by students are in various forms. This can also influence the student’s interests and learning outcomes of mathematics. But in fact, teachers are giveless attention to this problem so students tend to learn with less supported conditions and situations. This study aims to describe the level of mathematical anxiety and the forms of symptoms of mathematical anxiety that occur in early adolescents, and their influence on learning interest by gender consideration. The quantitative approach with the survey design of 404 students in junior high schools spread across Central Java and Yogyakarta Special Province was used in this study. Anxiety test instruments were used to collect premier data and interviews were used as supporting data. The results of the study showed that the mathematics anxiety level of the teenage as follows: Forget about mathematic lesson, more frekwntly breathing, having a thinking disorder such as difficulty concentrating and more afraid toface math test than other subjects The findings also show that gender influences mathematical anxiety, but mathematics anxiety does not significantly affect in learning interest.

The ArgumentIn the minds of many, the Bourbakist trend in mathematics was characterized by pursuit of rigor to the detriment of concern for applications or didactic concessions to the nonmathematician, which would seem to render the concept of a Bourbakist incursion into a field of applied mathematices an oxymoron. We argue that such a conjuncture did in fact happen in postwar mathematical economics, and describe the career of Gérard Debreu to illustrate how it happened. Using the work of Leo Corry on the fate of the Bourbakist program in mathematics, we demonstrate that many of the same problems of the search for a formal structure with which to ground mathematical practice also happened in the case of Debreu. We view this case study as an alternative exemplar to conventional discussions concerning the “unreasonable effectiveness” of mathematics in science.

One of the skills needed in learning mathematics is the ability to solve mathematical problems. In solving problems in mathematics learning, mathematical representation is needed by students in the problem solving process. Students tend to use mathematical representations, but sometimes they don't understand what they are doing. In general, mathematical representations also play an important role in improving mathematical competence. Beside the ability of representation, students also have intelligence, including mathematical logical intelligence, linguistics and visual spatial. This research is descriptive with qualitative approach that aimed to describe the complete mathematical representation of vocational high school students in solving a quadratic equation in terms.

We discuss different alternatives of the content of school mathematics. According to the prevalent public opinion in Lithuania school mathematics can be oriented either to the academic mathematics or to the applications of mathematics. In reality the second alternative means lowering of the level of teaching in the hope that school mathematics will be accessible to all students. While the content oriented to the academic school mathematics is accessible only to gifted students. In this article we describe a middle alternative content which we call school mathematics based on mathematical reasoning. We argue that such school mathematics serves all students and makes acquaintance with mathematical reasoning and with applications of mathematics to the real world. Reasoning makes mathematics reasonable for all.

Incorporating a diverse range of instructional strategies is essential to address the multifaceted nature of students' attitudes and motivations towards mathematics. Students' positive outlook and recognition of mathematics' practical utility in real-world scenarios are reflected in their ability to see the relevance of the subject to their future careers, which in turn reflects positively on their perception of mathematics. The purpose of this study was to explore the perceptions of students on the value of mathematics in their life and identify the components of mathematics learning that represents this perceived value. The non-mathematic-oriented college students (n=20) were purposively sampled. The one-on-one interview was conducted to extract the personal experiences of students and describe how they value mathematics. The findings indicated that the perceived value of mathematics involves its general use, personal use, and applications to human-essential processes or resources. Perceived value governs the practical relevance of mathematics in everyday life and signifies an opportunity to leverage this awareness for improved learning experiences. Educators should thus focus on nurturing this subjective valuing, tailoring instruction to align with students' individual preferences and highlighting how mathematical concepts align with their personal and career aspirations. This study underscored the need for a multidimensional approach to mathematics education – one that capitalizes on perceived value, addresses attitudes and difficulty perceptions, fosters intrinsic motivation, and promotes personalized and engaging learning experiences.

One factor in learning mathematics is the need for communication skills. Carpenter & Gorg (2000: 60) states "Communication is an essential part of mathematics and mathematics education", which means that communication is an important part of mathematics and mathematics education. Mathematical communication is related to problem solving, because with the existence of mathematical communication students will understand better in solving mathematical problems. This qualitative descriptive study aims to describe the written mathematics communication of junior high school students in solving mathematical problems in terms of students' mathematical abilities. The data obtained came from three subjects, namely VIII grade junior high school students who had received the material system of two-variable linear equations (SPLDV). The three subjects consisted of students with high mathematical abilities, students with moderate mathematical abilities, and students with low mathematical abilities. The results of this study are the accuracy of writing mathematics for high ability and medium ability students is declared accurate, but low abilities is not declared accurate. In the completeness aspect, high ability and medium ability students written mathematics communication is complete for any information that has been submitted. But, student with low abilities is not complete. In the aspect of fluency, students with high abilities are able to communicate fluently in mathematics, but students with moderate and low abilities cannot fluently. .

As mathematics teacher educators, we grapple with determining the depth of mathematical knowledge required of prospective elementary school teachers in our mathematical content courses. We struggle with identifying the mathematics appropriate for these courses as well as making the mathematics relevant for these teachers. If these classes are housed in a department of mathematics, as ours are, this discussion must take into account the expectations of our departmental colleagues. We examined these issues in spring 2001, when we were asked to redesign a mathematics content course for preservice elementary school teachers. In this article, we describe some of our experiences, including our decision to use middle school mathematics curricular materials as the primary textbooks.

Mathematical communication is an important part in learning mathematics. Mathematical communication is a way for students to express mathematical ideas either orally, in writing, pictures, diagrams, using objects, presenting in algebraic form, or using mathematical symbols. Through mathematical communication, students can convey ideas and clarify understanding and knowledge during the mathematics learning process. Mathematical communication skills are important because in learning mathematics, the use of notation, symbols, formulas and terms is a determining factor in problem solving. Due to the pandemic, learning activities are carried out online through Edmodo. This may bring changes to students' mathematical communication when doing a discussion. For this reason, this research aims to describe students' mathematical communication during discussion session in the Introduction to Geometry course through Edmodo. This research is a qualitative descriptive research. The subjects of this research were 35 students of first semester mathematics education who were taking the Introduction to Geometry course. The results showed that in doing a discussion, the students used written, visual, and symbolic mathematical communication. In expressing their opinion, students can also use more than one type of mathematical communication. In addition, the opinions expressed in the discussion were at various cognitive levels.

The importance of mathematical justification in all classrooms is emphasized by reform movements in mathematics education. However, previous studies reveal that encouraging justification in mathematics classes is troblesome for mathematics teachers at all school levels. This present study is aimed to find out how justification help students to develop their mathematical understandings. To answer this question, we first determined the role of justification in teaching and learning process and how good students in justifying their answers. Design research was chosen as an appropriate mean to achive that goal. The study was conducted in a state university in Yogyakarta involving four students from fifty-one students as our focus group and one of researchers as a lecturer. Justification was the focus on this study and to promote it we chose RME as an approach that served as a learning environment. In this study, all data collected from classroom observation, group observation, students’ works, video recordings, field notes during teaching experiment, and students’ final writen test. Students’ works then analyzed using a justification rubric and describe thoroughly by considering other data collected during teaching learning process. The study revealed that there were some roles of justification in RME classroom, namely encouraged conceptual understanding, supported mathematical skill, promoted long lasting skill, and influenced social relationship. In this study, most students in our focus group have already made a good justification which was assessed by the points in the CLEAR rubric. Students wrote their solutions equipped by signs or simbols, made labels, used a complete sentence to answer the question, and elaborated procedures throroughly

The recent study intends to describe the roles and the principles of integrating digital technology in education at the 4th Industrial Era. The integrartion is studied from mathematics education perspective. It is concluded that the basic principle of integrating digital technology in mathematics education is that the technology does not diminish students’ conceptual understanding or replace students’ intuitions in doing mathematics. Conversely, the technology is utilized to boost students’ conceptual understanding and maximize the development of students’ intuition in doing mathematics. It is identified that there are three didactical functions of digital technology in mathematics education, such as: (1) Technology for doing mathematics, that is the technology is incorporated as alternative learning media in doing mathematical activities; (2) Technology for practicing skills, that is the technology is utilized as a learning environment to master particular mathematical skills; (3) Technology for developing conceptual understanding, that is the technology is integrated as a learning environment to develop students’ conceptual understanding of specific mathematical concepts. This last didactical function is the most expected of integrating digital technology in mathematics education.

The importance of problem solving in mathematics has been attested to by many individuals and groups (e.g., Snowmass 1973; NCSM 1977; CBMS 1982). Furthermore, the belief seems to be common that the development of students' problem-solving abilities is one of the most important goals of mathematics education. In view of the importance of problem solving, it is templing to argue that problem solving and mathematical thinking are in fact different names tor the same activity. However, such an argument would provide too narrow an interpretation of mathematical thinking and too broad a view of problem solving. The purposes of this article are to describe one view of “mathematical thinking” and to describe the characteristics of a problem-solving program necessary to develop this kind of thinking.

Conic section in high school is an important carrier for cultivating students' mathematical literacy, but it is highly abstract and comprehensive, making it a "difficult point" in high school mathematics teaching. Hawgent dynamic mathematics software has powerful dynamic and visual functions, which can effectively assist the teaching of ellipse in high school. The questions to be studied in this paper are: (1) describe how teachers use Hawgent dynamic mathematics software to design learning media when teaching the content of conic section and stimulate students' for knowledge; (2) describe how Hawgent dynamic math software be used in class to help students understand the definition of conic section effectively. This research was used the research method combining ADDIE model and teaching experiment to analyze the class using Hawgent dynamic mathematics software to design learning materials and the class using traditional teaching method. Research sample was 130 high school students. Mathematical software design learning materials, can give students an intuitive presentation of the formation process of the conic, so as to help students effectively understand mathematical concepts and stimulate students' curiosity for knowledge.

In the U.S., state adopted or developed college- and career-ready mathematics standards, including the Common Core State Standards for Mathematics, not only impact districts, students, and their teachers, but also university teacher preparation programs. In order to attain and sustain Common Core’s vision of developing mathematically competent citizens, teacher preparation programs must support pre-service teachers’ development of practical conceptions of the Standards for Mathematical Practice. In this article, we examine the mathematical practices middle grades pre-service teachers (grades 4-9 licensure) and mathematics teacher educators identified as playing a role in attempts to make sense of and work toward solutions to mathematics problems. In addition, we compare the mathematical practices indicated both within and across pre-service teachers and mathematics teacher educators. Results identify pre-service teachers’ potential difficulties operationalizing six specific mathematical habits of mind. Finally, we describe how such comparisons can guide the design of future teacher education and professional learning by describing a process for identifying problems and tasks with the greatest potential to support pre-service teachers’ development of practical conceptions of mathematics or other content-specific habits of mind.

Exploration, inquiry, manipulation, discussion, and discovery all come to mind when we envision young children involved in mathematical activities. Early childhood education engages students in an exploratory journey from birth through age 9 in empirical mathematical concepts. The focus of early mathematics is to develop a strong foundation of the requisite skills and concepts throughout NCTM's five Content Standard strands (NCTM 2000). The wide ranges of abilities and understandings of mathematical concepts in early childhood classrooms challenge teachers to meet all students' intellectual needs. In this article, teachers of primary-grade multiage classrooms describe how they used scaffolding to capitalize on the wide ranges of abilities and met their students' needs by providing opportunities for their young learners to work together to understand mathematical concepts.

Ethnomatematics-based learning, linking mathematics and culture, can improve students' mathematical abilities. Therefore, the mathematical concepts contained in culture need to be studied to become one of the innovations in learning mathematics as a contextual learning material. This research aimed to explore and describe the cemetery complex of the Imogiri kings. This research was exploratory-qualitative research with an ethnographic design. The focus of this research was the ethnomathematics exploration of the buildings in the cemetery complex of the Imogiri kings. Research data collection was carried out through observation and documentation. The findings show that in the cemetery complex of the Imogiri kings, there are mathematical concepts that can be used as materials for learning mathematics. The mathematical concepts contained in the complex can be related to operational material for the addition of integers, comparisons, trapezoids, rectangles, congruence, similarity, beams, truncated pyramids, reflections, and rotations. The mathematical concepts from the ethnomathematics study can be used as materials for learning mathematics in schools, including at the elementary and junior high school levels.

Building on the work of Professional Noticing of Children's Mathematical Thinking, we introduce the Curricular Noticing Framework to describe how teachers recognize opportunities within curriculum materials, understand their affordances and limitations, and use strategies to act on them. This framework builds on Remillard's (2005) notion of participation with curriculum materials, connects with and broadens existing research on the relationship between teachers and written curriculum, and highlights new areas for research. We argue that once mathematics educators better understand the strategic curricular practices that support ambitious teaching, which we refer to as professional curricular noticing, such knowledge could lead to recommendations for how to support the curricular work of teachers and novice teachers in particular.
