Chemistry and chemical technology contribute to the quality of life on this planet in many areas: health, nutrition, agriculture, transportation, materials and energy production, and industrial development. Chemistry is at its most useful to society when chemists and non-chemists with decision-making responsibilities work with mutual understanding to address the chemistry-related issues facing their communities. Thus, it would seem obvious that all who study chemistry should learn about the interactions of chemistry and society as an integral part of their classroom instruction. However, historically, the tendency worldwide has been to include societal content in chemistry courses only at the lower secondary level. This is changing. This paper explores instructional materials developed by the American Chemical Society that place chemistry in its societal context for high school and college students. This includes a discussion of green chemistry materials that introduce students to the concepts associated with developing environmentally benign processes and products.

The vital necessity of descriptive geometry and graphic study by students which are training in the specialties of chemist and chemistry technologist is shown. It is concluded that any engineering and scientific creativity in modern chemistry as the science of materials, structural chemistry and chemical dynamics of molecular systems’ interaction process is impossible without the foundations of descriptive geometry, which forms and develops the human spatial thinking. The discovery of conformational transitions in molecules and, in the future, conformational analysis, has predetermined the broad use of descriptive geometry methods in the chemical science. The modern chemistry’s state analysis is leading to conclusion that at present time the descriptive geometry is needed in the educational program of modern chemist and chemistry technologist.

Increasingly, chemists are faced with legislation requiring assessment of hazard and risk associated with the production, use, and disposal of chemicals. In addition, the general public are concerned about the dangers that they hear may result from the widespread use of chemicals. They look to the chemist for explanations and assume that chemists understand such matters. When they discover that chemists are often ignorant of the potential of chemicals to cause harm, their confidence in the profession is lost and chemophobia may result. In 1993, IUPAC agreed on a joint project between the Toxicology Commission and the Committee on Teaching of Chemistry to address the issue of the teaching of toxicology in the chemistry curriculum. Part of the project was a distance learning program, which is available through the Internet and on CD.1 The program currently consists of seven modules, one of which deals specifically with environmental toxicology. The contents of each unit will be explained as each has some input into environmental matters and green/sustainable chemistry. The program is aimed at teacher and student alike, and each module has self-assessment exercises at the end of the module. Additionally, there is material on health and safety, ethical matters, and a case study of the use of dichlorodiphenyltrichloroethane (DDT).

Predict-observe-explain (POE) is a strategy being used during scientific investigations and experiments. However, POE-related studies mainly focused on its validity and reliability as a teaching strategy in classrooms. Thus, this paper extends the context of POE discussion not only as a teaching strategy but also as science process skills, and as cognitive thinking skills in performing experiments and answering scientific inquiries among chemistry stakeholders: students, teachers, and chemists. The study sees POE as a way to develop critical thinking and builds the skills needed for further academic and professional endeavors in the different fields of science. Through a constructivist grounded theory methodology using focus group discussions for students and in-depth interviews with the teachers and chemists, the study: described how students, teachers, and chemists exemplified POE strategy in terms of its process, and identified mutual patterns of POE process from the chemistry stakeholders. The study revealed that: student POE taxonomy is focused on basic processes and structures of POE; teacher POE taxonomy is a guide in their lesson planning; and chemist POE taxonomy is based on local and international compliance during experimentation. Therefore, POE is a science process skill for chemistry stakeholders where the POE taxonomy used by the chemistry stakeholders are different based on experiences, needs, and context.

Teaching and learning science are major challenges that require media as facilitators for their understanding and view of the world, within this framework, it is the chemistry. The present study aimed to verify as the use of didactic resources for the performance in science teaching using a dynamic relationship of content. The methodology consisted of a field research, the qualitative divided into four stages, being employed lectures to explore the theme linking the practice and theory, using educational tools (experimentation, electronic game alternate) as sources for data analysis. Before the application, it was observed that after the trial the majority of students felt difficulty in combining theory with practice, on the basis of this difficulty it was noted that 50% consider experimenting a way supportive for the understanding of the subject, as well as provide discussions and dialogs (25%), and demonstrate chemical reactions (25%). The application of the game alternative teaching allowed students with a sense of knowledge in chemical life by promoting the development of a critical vision of the world. It was concluded that, for a student-teacher relationship-discipline is necessary to perform various steps, since the prior knowledge, the arguments, the inquiries, analysis of responses, to then carry out the explanation of the subject together with the use of didactic resources.

The study investigated the knowledge of chemistry teachers in using group work as a teaching strategy in teaching chemistry at the senior high schools (SHSs) in Ahafo and Bono Regions of Ghana. The sequential explanatory mixed method design was adopted for the study. All 58 chemistry teachers in the 20 purposively sampled SHSs participated in the study. A structured questionnaire, interview guide and an observation checklist were the research instruments. The descriptive techniques used for the analysis of data were percentages, means and standard deviation while Chi-square used for inferential analysis. The results revealed that a statistically significant number of chemistry teachers were knowledgeable in the use of the cooperative teaching strategies but adopted it occasionally based on unavailability of time and resources. The study recommended in-service training and workshops be organized on the impact of group work as a teaching strategy to enhance chemistry teachers understanding and motivation to use group work more frequently in their teachings. This promotes active learning among students through debates, questioning and discussions.

Micro-polymer chemistry experiment teaching had such characteristics as using less reagents, less pollution and more portable in comparison with the conventional experiment, with the significant progress, more than thirty years ago. In China, Zhou Ninghuai and others firstly began to go on micro-scale experiment research and Professor Li Qingshan who brought this innovation to polymer organic synthesis experiment has done a lot of works in micro-polymer chemistry experiment teaching. To carry out the study of micro-polymer chemistry experiments not only accords with teaching methods and reform, but also conforms to the trend of the times of green chemistry. The research and application of micro-polymer chemistry experiment have broad prospects. The microscale chemistry experiment (ML) is developed from the idea of green chemistry and the prevention of chemical industry. Microscale chemistry presents a low-cost and green approach in the teaching of chemistry laboratory courses, so it’s the reform of traditional chemical methods. In micro-chemistry experiment, most of the raw materials are in the amount of quality 1g or volume of 1mL below, in line with famous micro-chemist Professor Ma Zusheng[1] (Prof • T. S. Ma), who put forward that "It is to use the chemical reagents as low as possible to obtain the necessary technology information in microscale chemical experiments". In contrast to conventional macroscale chemistry experiment, the micro-chemistry experiment can not only reduce the running cost of laboratory teaching, but also alleviate the potential hazard sassociated with chemistry experiments.

Almost every country in the world is obligated to implement education policies to enable an inclusive school system. However, implementing techniques to be inclusive in schools is a major challenge to teachers, especially to those teaching a subject at secondary level and higher. Most of the literature concerning inclusive science education was published in recent years, and is more normative than empirical. Teachers struggle to transfer these normative demands to their accustomed way of teaching science. In this study, we analyze conflicts a teacher experiences when teaching a so-called ‘hard science’ like chemistry at an inclusive school. On the one hand, inclusive science education should facilitate participation in science specific learning processes for all learners. This broad perspective on inclusion demands that everyone can take part in everyday classroom life. On the other hand, chemistry strives for the understanding of abstract concepts, theories and models, which forms a barrier to learning chemistry for many people. This paper presents an explorative case study focusing on these conflicting demands. To reconstruct the inconsistencies, we analyzed a videotaped teacher–student discourse on atoms. Using the documentary method, a qualitative approach developed by the sociologist Ralf (Bohnsack et al., 2010). distinguishing between explicit and implicit knowledge, it was possible to reveal the orientational frameworks guiding the teacher’s actions. On the surface level, traditional scientific educational approaches structure the discourse. Reconstruction of the discourse is deep, as evidence was found for a participation-oriented framework as well as for the challenges the conflicting demands of chemistry and inclusive teaching put on teaching. We implicate that future professional development courses must not only concentrate on combining chemistry with inclusive pedagogies, i.e., how to teach, but also on the reflection of implicit beliefs concerning inclusive chemistry teaching.

In this study, we examined the effect of School Experience (SE) and Practice Teaching (PT) courses on pre-service chemistry teachers’ beliefs towards chemistry teaching over a one-year period. To reach this purpose, participants’ beliefs and experiences towards chemistry teaching were monitored closely throughout the varied phases of the two practicum courses. Two pre-service chemistry teachers participated in the study. Data were collected via semi-structured interviews, observation notes, CoRes and reflection papers. Semi-structured interviews focusing on the pre-service teachers’ beliefs regarding chemistry teaching were conducted three times while participating in the SE and PT courses. During the PT course before their teaching experiences the participants prepared CoRes, and after their experiences they critiqued their own performances. Moreover, the participants were observed during their student-teaching experiences to identify how they transfer their beliefs into their teaching. Data were analyzed via inductive analyses. Results indicated that both pre-service teachers had stable core beliefs derived from their own experiences as students that remained constant during these courses and guided their practical instruction. Although both participants attended the same courses during the teacher education program, their attitudes while taking the educational courses were different. Factors that shaped pre-service teachers’ beliefs towards teaching were presented as the practicum courses enriched with CoRes and reflection papers, observing their mentors, experiences gained from microteaching sessions, and pedagogical and methods courses taken during the pre-service teacher education program. Implications for the formation of pre-service teachers’ beliefs towards teaching throughout pre-service teacher education programs were provided.

Background: It is considered that, in order to teach, the teacher must have a base knowledge inherent to teaching and that the self-concept can influence the construction of this knowledge. Objectives: To analyse the correlation between teacher knowledge and self-concept. Design: This investigation began with a study on self-concept and teaching knowledge so it would be possible to build the theoretical framework that would support the collection and analysis of data. Setting and Participants: the participant of this research was a teacher who had been teaching chemistry for over 22 years in southern Brazil. Data collection and analysis: The body of data that constitutes this research permeates the analysis of semi-structured interviews, observations in pre-service teachers’ diaries and teaching materials (such as biweekly plans, appraisals, among others). The analysis categories were the teaching knowledge model called the Hybrid Model and the self-concept categories: affective, cognitive and behavioural. Results: The components of teacher knowledge that most emerged were General Pedagogical Knowledge, Content Knowledge and Knowledge of Instructional Strategies for Science Teaching, while the most emerging self-concept categories were Behavioural and Cognitive. The categories that most occurred were General Pedagogical Knowledge with Behavioural Self-Concept. Thus, it is understood that the way that this teacher interacts with his school space strongly influences the way he constructs his teaching practice. Conclusions: It is inferred that this connections can influence the construction of teaching knowledge of experienced and novice teachers. A better understanding of this process can help in understanding the teaching profession and, consequently, in predicting the efficiency and satisfaction of teaching practice, as well as pointing out possible ways to train chemistry teachers.

The study evaluates chemistry curriculum at the secondary level. Chemistry is the science subject which help in technological advancement. It deals with the study of composition, structure, properties, and different changes which take place in matter. There are different careers in chemistry such as in food processing, industries, health etc. The progress of any country depends on the achievement in the field of chemistry. The successes of these reforms are associated with chemistry curriculum. Therefore, this study re-examines the objectives of National Chemistry Curriculum 2006 and identifies the nature of implementation of chemistry curriculum. Questionnaire based data from 138 chemistry teachers (male and female) teaching at secondary level in District Haripur determined that modern teaching techniques are required in teaching chemistry. So, it is recommended to improve curriculum at regular intervals according to global standards.

Before the covid-19 pandemic paradigm, the education sector has been facing several challenges. Especially in the Chemistry area, the subjectivity and complexity conditions are admitted by many students when it is about teaching the content of this science. Furthermore, the promotion of active methodologies for teaching Inclusive Chemistry is deficient, mainly, methodologies which contemplate the particularities of the deaf community. In this context, the purpose of the present work is to offer remote teaching activities that addressed the content of Organic Chemistry in a contextualized way with environmental awareness regarding Urban Waste (RU), involving the principles of Inclusive Education (IE) for a high school class consisting of hearing and deaf students from a public school in Brazil. As for the methodology, the research was based on a qualitative and participatory perspective. Aiming at a methodological proposal which contemplates the students´ educational gaps, especially the deaf population, such as accessibility in Brazilian Sign Language (LIBRAS), the classes were contextualized with support by Digital Information and Communication Technologies (TDICs). Based on the activities carried out in the school environment, it was possible to verify continuous participation of all students, especially, in the activity which involved the water pollution simulator using the "Mozaik Education" software and showing how water pollution occurs upon contact with wastewater in a safe way. Therefore, the teaching resources used in this study were efficient, because they are facilitating agents in the knowledge acquisition process.

Organic chemistry is a subject which students find difficult because of complex reactions and mechanisms involved. The main aim of this study was to study the students' understanding of the concepts of organic chemistry by pattern based teaching method (PBT). Pattern Based Teaching is a systematic approach in teaching chemistry where the reactions and mechanisms are systematized into a particular pattern for different functional groups. The students are made to understand the basic concepts how to introduce a particular functional group and how functional groups give reactions with different type of reagents. The present paper reports the effect of this innovative teaching method on students' long term retention of organic chemistry course material. Long term retention of contents was examined by conducting two tests-pretest (based on traditional lecture teaching) and a post-test (conducted after PBT). Students' of first year undergraduate class of two different colleges of Kishangarh city of Ajmer district of Rajasthan were used for the study. These students were divided into six groups and two of them were taught by the author by PBT method. The rest four groups were control groups taught by the traditional lecture based teaching method. Students performance after PBT method was compared to that in a traditional lecture based teaching method. Our analysis showed that the out of the six sample groups of students used in our study, the highest mean scores (10.46 and 13.36) were of the two experimental groups. The four control groups had mean scores in the range 7-10. This investigation thus suggests that pattern-based teaching in organic chemistry is a powerful and systematic approach which facilitates students’ long-term retention of contents of the subject. It promotes active learning and creates students’ interest in the subject.

Industry 4.0 has transformed many aspects of society, requiring high-quality human resources. The General Education Program 2018 has identified STEM education as one of the teaching methods that contribute to the formation and development of learners' qualities and competencies. Chemistry is a subject in high school with a close connection between theory and experiment, with many opportunities to develop students' abilities. This article introduces the development of the ability to study the natural world from in chemistry perspective through STEM teaching in the nonmetallic part of Chemistry 11. Through teaching the topic "Greenhouse effect", students have developed the ability to study the natural world from a chemical perspective. The pedagogical experiment has shown that the experimental class has a higher level of competence than the control class and the difference is statistically significant.

It is clear that use of images has effect on teaching the chemistry concepts. In classrooms, some examples which are used for simplifying and understanding the material better are in macroscopic dimension and students do not understand particles such as atoms, molecules and ions well. In order to help them understand these concepts in macroscopic dimension, illustration is used. In illustration, students can reflect different concepts of chemistry which have learnt during teaching. One of the illustration methods is to use painting art, as one can determine the extent to which they have understood from chemistry concepts and relationship among different areas of the sciences, society and technology by studying paintings of these students. The Aim of this research is to determine through their paintings whether students have understood the taught concepts in chemistry of the first grade of high school in IRAN or not. These chemistry subjects include water, atmosphere, minerals and fuel. After teaching the above topics, the students were asked to select a subject at their will and paint about it. This research has been performed in two separate cities in IRAN but it has been implemented in equal age groups and it was specified that different places of residence had effects on selection of painting subject. Our experience showed that use of this method led to deep learning in the students and provided the opportunity for them to express their beliefs in scientific concepts in their own way and language. On the other hand, teacher performs a kind of continual evaluation in this way and understands students’ misconceptions and tries to remove these errors before beginning new subject. This method is interesting for students so that most of them mentioned that painting the chemistry was new and interesting experience.

The training of teachers at educational science faculties prepares them better to deal with class management, individualization of teaching, evaluating, problems with motivation, etc. Teachers educated at chemistry faculties have a profound and well-established knowledge in the field of chemistry, but they demonstrate limited pedagogical skills. Recently, the collaboration between chemists, researchers in chemistry education and chemistry teachers has become more intense. In 2013, the Jagiellonian University joined the 7th Framework Programme project – IRRESISTIBLE (http://www.irresistible-project.eu). The goal of the project IRRESISTIBLE is to design activities that foster the involvement of students and the public in the process of Responsible Research and Innovation (RRI). A case study based on the example of the IRRESISTIBLE project is presented. Some interesting results are discussed. Key words: educational science, science education, teacher education.

This study is aimed at development chemistry students’ study skills through integration of visual organizers (VOs) in teaching English for Special Purposes (ESP). The research specifically examined the students’ attitude toward the chemistry content of English classes and the achievement of two groups of 54 students under study. The results of the study indicated that there is a significant difference between the level of study skills in dealing with chemistry in English of the students in the experimental group before and after the experiment. The result of students’ perception about visual organizers, as a strategy and approach to teaching English through chemistry, highlighted the rаtionale in this undertaking. All communicative activities and presentations used by the teacher in the class incorporating visual organizers in identified formats such word webbing, web diagram, flowcharts, concept maps, Venn diagram and pictorial graphics obtained a positive perception of chemistry information in English. Performance, on the other hand, indicated the VO’s effectiveness in facilitating the learning of English and study skills development. This analysis implied that the experimental group performed significantly better than their peers in the control group. Facilitating English learning through chemistry content can be made through integrating visual organizers that help develop students’ study skills. Hence, the use of visual organizers effect changes in learning chemistry content for the better. Visual organizers help students perform better and improve their attitude toward learning English for professional communication.

Few would deny that teachers play a decisive role in the learning-teaching process of students. The learning-teaching process with a gender equity perspective is an important tool to improve the participation and success of women in chemistry. The learning-teaching process with a gender equity perspective was analyzed using the final scores of two taught modules along with molecular models, students’ drawing of flow diagrams, and open-book examinations. Data collected over a 15 years’ period were subject to χ2 testing using Statistical Package for the Social Sciences Software. Results found that the interaction effect between final scores and gender was statistically significant in the module of organic chemistry of drugs but not in the case of the module on drug production, which dealt with physical chemistry subjects. The significance of this study indicates that the teaching methodology used could help female students to learn both chemistry and physical-chemistry with better or similar outcomes than male students.

This research aims to draw a picture of chemistry lessons based on students’ opinions in Hakkari, Turkey. The research design is a case study. An open-ended qualitative questionnaire consisting of 15 questions was used. The questionnaire was applied to 463 tenth- and eleventh-grade students studying at high schools in Hakkari. The data obtained were analyzed using qualitative and quantitative methods: content analysis, correlation tests, and chi-square tests. As a result, two categories were found: the factors affecting chemistry teaching and the effect of chemistry on students’ daily and future lives. According to this, students’ interest in chemistry is a factor in learning chemistry, the teaching method used by the teacher is an essential factor for chemistry, and having enough knowledge of chemistry affects achievement in other courses. A significant difference was found between female and male students choosing chemistry in their future careers, and the results were in favor of male students. On the contrary, female students thought that chemistry would be more permanent than males thought in their lives. The activities used in chemistry lessons, teachers’ attitudes in the classroom, and the use of chemistry examples in daily life are effective for learning chemistry and choosing chemistry for a future career.

This article addresses the history of how chemists designed syntheses of complex molecules during the mid-to-late twentieth century, and of the relationship between devising, describing, teaching, and computerizing methods of scientific thinking in this domain. It details the development of retrosynthetic analysis, a key method that chemists use to plan organic chemical syntheses, and LHASA (Logic and Heuristics Applied to Synthetic Analysis), a computer program intended to aid chemists in this task. The chemist E. J. Corey developed this method and computer program side-by-side, from the early 1960s through the 1990s. Although the LHASA program never came into widespread use, retrosynthetic analysis became a standard method for teaching and practicing synthetic planning, a subject previously taken as resistant to generalization. This article shows how the efforts of Corey and his collaborators to make synthetic planning tractable to teaching and to computer automation shaped a way of thinking taken up by chemists, unaided by machines. The method of retrosynthetic analysis made chemical thinking (as Corey perceived it) explicit, in accordance with the demands of computing (as Corey and his LHASA collaborators perceived them). This history of automation and method-making in recent chemistry suggests a potentially productive approach to the study of other projects to think on, with, or like machines.

The disciplines curricula on green chemistry and sustainable chemistry available in various universities of the world were analysed. Trends in education development and science in this particular area were described as well as actual green chemistry teaching problems that need to be solved. Analysing the data obtained three approaches defining a trajectory for teaching the basic foundations of green chemistry were identified: British, European, and American. The first one involves in-depth study and the formation of competencies in the field of green chemistry. The second approach implies the inclusion of green chemistry in traditional chemical disciplines (organic, analytical chemistry, etc.). The third approach implies the inclusion of green chemistry as a module in such practice-oriented disciplines as biotechnology, food safety, ecology, etc. The content of the laboratory classes in green chemistry curricula and the usage of a green chemistry metric «green star» for assessment of their safety are discussed. It is proposed to join efforts of different countries for green chemistry ideas promotion and transfer the green chemistry ideas through creation of green chemistry centers of excellence for the use of its principles and methods in scientific research and the educational process.

This study investigated the implementation of best teaching practices by science graduate teaching assistants [GTAs] (3 chemists and 2 biologists) in five inquiry-based, interdisciplinary chemistry-biology experiments during a six-week professional development (PD) program,EngagePD. Additionally, we examined GTAs’ experiences in implementing specific PD aspects. The PD program took place as the GTAs taught sections of biology and chemistry laboratory courses, each comprising five interdisciplinary experiments. The PD aspects included defining expected learning outcomes, subject-matter knowledge, relevance to real-world and chemistry-biology connections, and other active classroom teaching practices. Data were collected through classroom observations, reflection questionnaires, and individual interviews. Findings indicated that 57% of the PD aspects investigated were implemented in the five interdisciplinary experiments. Results also revealed GTAs’ initial areas of struggle in implementing specific PD aspects. Perceived implementation difficulties were attributed to individual perceptions and beliefs, and contextual factors. Through practice, continuous feedback, and reflections, most GTAs overcame the hurdles and refined their teaching. Findings imply the need to design training PD programs that offer mentoring and support to GTAs and future faculty in implementing teaching innovations. The teaching context and reflection prompts are helpful in identifying areas of difficulties and how to improve.

As science fiction has a way of capturing the human imagination that few other genres can rival, this study sought to investigate the effects of using science fiction on the performance and interest of high school chemistry students. An action research approach was used to guide the first author’s practice as she studied two college preparatory chemistry classrooms. One class was used as a control group and received traditional chemistry instruction through lecture and labs. The second class was provided with supplemental excerpts of science fictional reading and film. Student scores on a pre-assessment and post-assessment achievement test items were analyzed and supplemented with student interviews and field note observations, and a teacher reflective journal was used to complement achievement data and inform findings regarding the effectiveness of including fiction as a pedagogical choice. Implications for this study on teaching tools, methodologies, and curriculum development are discussed.

The Ghana Education Service has employed two categories of chemistry teachers who are expected to deliver in line with a set standard of teaching and assessment. The study investigated professionally trained chemistry teachers and untrained chemistry teachers using Shulman’s PCK model. The study investigated their knowledge of teaching and assessment. A multi-case study design was used to investigate multiple knowledge domains of chemistry teachers in senior high schools within the Tamale Metropolis in the Northern Region. One hundred fifty chemistry students and 12 chemistry teachers were selected through a random sampling technique, and in one of the schools, a convenient sampling technique was utilised. The study employed questionnaires, interviews, and classroom observation to solicit data from the participants. The quantitative data gathered was analysed by employing descriptive statistics and paired sample t-tests. The qualitative data was analysed by developing common themes and patterns in the respondents’ responses. Comparatively, the findings revealed that the professionally trained chemistry teachers exhibited higher knowledge of teaching and assessment in chemistry than the untrained chemistry teachers. Case-by-case analysis and comparison of the findings indicated that some untrained chemistry teachers exhibited higher knowledge in teaching and assessment than some of the professionally trained chemistry teachers. It was therefore recommended that colleges of education and universities that train teachers should concentrate on the pedagogical development of chemistry teacher trainees. Content knowledge alone would not ensure professional teaching of chemistry. Ghana Education Service, in collaboration with other governmental and non-governmental agencies, should periodically organise workshops and seminars for in-service chemistry teachers’ professional development to be trained in modern pedagogical trends. In-service chemistry teachers should be given opportunities for further studies to learn and discover emerging methods and strategies for teaching chemistry

Practicing chemists use models, diagrams, symbols, and figures to represent phenomena which cannot be detected by the human senses. Although research suggests that these external representations (ERs) can also be used to address the challenges that students have in learning chemistry, it is not clear how instructors' use of ERs aligns with their perceptions of student learning difficulties. In other words, do instructors use ERs to address what they perceive as students' major challenges in learning chemistry, or are they using ERs for other reasons? The answer to this question could have implications for the professional development of chemistry instructors, including both classroom instructors and laboratory facilitators. As a pilot study to guide the development of a larger project focused on the use and interpretation of ERs, we interviewed eleven general chemistry teaching assistants at a major university in the U.S. Southwest about their use of ERs when facilitating acid–base titration laboratory activities. Our data suggest that there is a lack of alignment between teaching assistants’ primary reported use of ERs and the primary challenge that they perceive their students have when learning about acid–base titrations. We discuss potential reasons for this misalignment, as well as implications for teaching assistant training related to the use of ERs in the laboratory learning environment.

The study aims to reinforce the effective teaching of chemistry in secondary schools through the support of the school leadership in the implementation of the competence-based curriculum (CBC). Interviews were organised and conducted with five headteachers and five deputy headteachers from ten selected schools. The results confirmed that the support provided by the school leadership in teaching chemistry was dominated by 30% of respondents at visiting teachers in classes, provision of some basic teaching materials and encouraging teachers to work in the chemistry department for mutual support and professional growth. However, in some schools, there is a need for prioritising continuous professional development (CPD) opportunities, feedback meetings and analysing school data for decision making. Therefore, this study recommends more efforts in CPDs, avail enough teaching aids and hold the pedagogical review and learning meetings lead by headteachers; analyse and use the school data for continuous improvement and build the school on tangible evidence in positive learning outcomes. Plus more support in engaging learners doing chemistry rather than just giving them chemistry books. Transformational leadership is needed, where all stakeholders share the same vision and mission of the school.

The article presents the experience of teaching chemistry to foreign students of a medical university. To facilitate the understanding of educational material in chemistry by foreign students, the didactic potential of university lectures has been expanded. Every year, Russian universities accept citizens from more than 170 countries to study. The annual growth in the number of foreign students corresponds to the national course for further integration into the educational and scientific community of the allied states. The relevance of the study is determined by the need of Russian universities to develop educational and methodological materials in a foreign language for training programs for foreign students. The aim of this study is to facilitate the understanding of lecture material, and, as a result, to increase the effectiveness of teaching chemistry to foreign students of a medical university through the use of an English-language course of lectures in the learning process. Within this work, using the method of students questionnaire survey, a pedagogical study of the attitude of foreign students to the use of a course of chemistry lectures in English was carried out. The study involved 80 foreign students of Altai State Medical University, citizens of far abroad countries. It was found that the described course of lectures minimizes the difficulties of foreign students' perception of large amounts of educational material (97.5% of respondents), increases the efficiency of independent work (92.5%), helps to overcome the language barrier when teaching in an intermediary language (67.5%), as a result, there is a general interest of foreign students in chemistry as a science (95%), facilitating of educational material understanding and an increase in academic performance (96.2% of those who successfully passed the exam in chemistry compared to 60% of students in the control group). Thus, we came to the conclusion that the use of a developed English-language course of lectures in the teaching chemistry makes it easier for students to perceive the lecture material and improve the quality of chemistry education for foreign students.

Purpose This paper aims to discuss the knowledge levels, attitudes and behaviours regarding the concept of sustainable development among pre-university programme educators, as well as the potential barriers and opportunities they face in adopting the concept of sustainable development in the teaching of the pre-university level chemistry module at a public university in Malaysia. Design/methodology/approach A survey was conducted with eight educators of a pre-university programme at a public university located in Selangor, Malaysia. This pre-university programme exposes students to advanced courses in science, which are very much like first-year university courses for candidates who are interested in gaining admission to degree programmes. For this study, the focus was on chemistry educators only. The collected data were analysed through descriptive analysis following which interviews were conducted with the respondents. Findings In general, the educators have good knowledge and attitudes towards the concept of sustainable development. Moreover, their projected knowledge (K), attitude (A) and behaviour (B) focus more on environmental dimensions, as opposed to other sustainable development dimensions. While the integration of the concept of sustainable development in chemistry teaching is restricted by a few barriers, such as content-based learning, lack of guidebooks related to sustainable development and an overcrowded curriculum, positive responses from the chemistry educators indicate that there are opportunities to implement sustainable chemistry concepts in the pre-university chemistry module. Research limitations/implications The present study was conducted with several limitations; the data were obtained from a small sample size at an institute located within a public university. The respondents of this research consisted of only three existing chemistry educators and five administrators who are also educators. Further studies about sustainable chemistry teaching should include samples from other public and private universities. Originality/value This paper is instrumental in assisting the Ministry of Education, administrators, as well as educators within the pre-university sector to shift their goals towards sustainable chemistry teaching to achieve success in education for sustainable development.

This paper selectively reviews both early and more recent work by the author on the teaching of chemistry at secondary level. The purpose is twofold: (i) to review the proposals, their features, and the research behind them, (ii) to emphasize the strength over time of the work presented, but also the need for constant revision. The reviewed topics for lower secondary education (7th-9th grades) include: a revised curriculum (1984); a study of Greek students’ contextual chemistry knowledge (1987); an updated proposal about the curriculum (2001); an integrated physics and chemistry program for the 7th grade (2000), that has been further developed recently (2011) to include biology; two research studies on teaching methodology (2000)’; a chemistry course for the 8th grade (2010); revision of the current formal Greek chemistry curriculum (2014). The reviewed topics for upper secondary education (10th-12th grades) include: three early (1981, 1985a, 1985b) studies on Greek students’ strengths and difficulties with chemistry; a context-based chemistry curriculum (1988, 1991); proposals for new chemistry curricula (2000, 2011, 2014) for the 10th and 11th grades. Coupling to the PARSEL modules is also made. The paper concludes by making reference and connection to the work of Hans Jürgen Schmidt.
