The aim of this study is to determine the pre-service teachers' perceptions of atom and atomic structure through a word association test. It is important to concretize the concepts having a significant influence on the learning of subjects. Through this concretization, students' understanding of the concepts and accordingly of the subjects is…

The present study reports an empirical investigation into concept formation of young children. Based on interviews conducted before and after participating in a playfully enacted chemistry lesson at a culture center, it is analyzed how 6-year-old children conceptualize water, molecule, and chemistry. Theoretically, the study is informed by…

The International Union of Pure & Applied Chemistry (IUPAC) launched a global project in 2017 to infuse systems thinking into chemistry education, motivated in part by the desire to help equip chemists and citizens to better address the complex, global challenges our society currently faces. One important early outcome of the IUPAC Systems…

Various international perspectives from selected regions where substantial work is being done on green and sustainable chemistry education emphasize a systems thinking framework. Common to most of the perspectives is the inclusion of more global paradigms involving economic, environmental, political, and social aspects as fundamental issues in the…

Phosphates are essential components of any efficient fertilizer. Natural phosphate rock is, however, not available in every part of the world. According to the European Commission, phosphate rock has high economic importance as well as a certain supply risk--at least for Europe. For these reasons, environmental technology research has received a…

The development of students' interest in school science activities, their understanding of central chemical concepts, and the interplay between both constructs across Grades 5-11 were analyzed in a cross-sectional paper-and-pencil study (N = 2,510, mean age 11-17 years). Previous empirical findings indicate that students' knowledge increases over…

A storytelling approach has been seen as a powerful way to teach science and arouse interest and promote positive attitudes toward learning science in the early years. The purpose of our study was to determine how middle school students -- Key Stage 3 (KS3) aged 12-14 in Portuguese schools -- experienced learning chemistry through storytelling and…

Demands are placed on undergraduate courses in chemistry to develop transferable skills, such as teamwork, alongside subject content and technical skills. Such skills can be developed by implementing pedagogies which involve students working together. Such pedagogies can, however, pose various challenges, including unfavourable student perceptions…

Active-learning strategies such as undergraduate research courses and course-based undergraduate research experiences (CUREs), which engage students in the practical experiments, have been reported as efficient ways for effective teaching and training of graduating students. Recently, many practical examples have been published in various fields…

This study provides an analysis of selected aspects of the intended curriculum related to redox reactions as represented in secondary chemistry textbooks from the People's Republic of China, with a special view also on Hong Kong, Shanghai, Taiwan, and the Chinese minority in Malaysia. This study reveals how chemistry textbooks deal with visual…

Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, which reinforce the learning of all students in general. This paper presents simple teaching resources that allow students…

The effects of substitution on reaction rates are at the heart of both physical chemistry and organic chemistry. In this paper, we present a computational laboratory module to explore the effects of group substitution and isotopic substitution on reaction rates by using a readily accessible graphical interface, a computational engine, and…

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students' mechanistic…

Purpose: This paper aims to investigate the knowledge, attitude and behaviour of foundation chemistry learners concerning the sustainable development concept. Design/methodology/approach: Qualitative and quantitative studies were conducted. Atlas.ti software was used to analyse the chemistry curriculum based on selected themes and sub-themes. A…

This article describes a five-lesson curriculum that introduces students to the primary cause, multiple predicted impacts, and possible solutions to ocean acidification. It builds upon the strengths of over 90 existing teaching resources on the topic while also contributing new ways to teach about the impacts and solutions to this pressing…
