This study investigated the effect of interactive computer simulation-supported inquiry on South African grade 8 learners' comprehension of atoms and molecular structures. Two sample groups of 34 learners per sample group were used, one acting as a control group who were exposed to a teacher-directed pedagogy while the experimental group used…

Over 1.7 billion students around the world have had their education disrupted by the spread of the Coronavirus disease worldwide. Schools and universities have not faced this level of disruption since World War II. The COVID-19 pandemic presented a colossal challenge for teachers to urgently and massively adapt all their classes to distance…

Sustainability has become a prominent theme in society and can be considered as an integral part of scientific citizenship. This study investigates to what extent the production, use and re-use of (bio)plastics initiates students' reasoning and to identify the kind of content knowledge students put forward. The structure of students' arguments was…

In the past twenty years there has been a surge of research on chemistry students' attitudes, self-efficacy, self-concept, expectations, values, interest, motivation, effort beliefs and achievement emotions. This research has sought to understand how students feel when learning chemistry and how this may be influencing how they perform. However…

In previous published articles, formulae-based mnemonics by counting the total number of s bonds with a lone pair of electrons (LP), a localized negative charge (LNC), or a localized lone pair of electrons (LLP) and subtracting one (01) from this total value (TSLP, TSLNC, or TSLLP) to predict the power of the hybridization state of simple…

The term "Virtual Reality" currently refers to a profound sensory immersion of the user in a synthetically generated virtual environment. It is foreseen that virtual reality will gain a substantial role in the instruction of science. In this literature review, the purpose was to investigate the research on the utilization of virtual…

Research points to the important role achievement emotions play in academic performance and career choices, yet few studies have examined achievement emotions in non-Western contexts. The current study extends this research base by examining students' achievement emotions among 103 eleventh-grade high school chemistry students in China. Using…

The overall aim of the present study is to study model-based teaching and the collaborative inquiry learning of chemical processes and physical phenomena in preschool, with a specific focus on the verbal communication established between teachers and children (4-5 years old). According to variation theory, learning is always directed at a specific…

Graduate teaching assistants (GTAs) play an essential role in the teaching of introductory chemistry courses at many higher education institutions. On the basis of best practices suggested by the literature, we developed our GTA training course to focus on modeling best practices in the classroom, providing opportunities for incoming GTAs to try…

We developed a comprehensive training module for the undergraduates majoring in chemical education with a simple microfluidic experiment. The students were required to read a scientific reference offered by the instructor, then design and implement a microfluidic experiment for real sample analysis by making some modifications to the method…

The Coronavirus disease 2019 (COVID-19) pandemic in China has changed higher education dramatically, with a distinctive rise in online instruction. Here, we describe the major successes and challenges encountered during the full implementation of online chemistry instruction in higher education in China based on questionnaires answered by 56…

This research explored science teachers' perceptions of BBL. Data was collected from 105 Saudi Arabian science teachers via a questionnaire survey, establishing how BBL is viewed and applied, and whether this interrelates with teachers' years of professional experience or qualification level. Furthermore, in a quasi-experiment comprising a single…

The mole concept is one of the fundamental concepts in chemistry. However, a number of studies carried out in various countries have shown that teachers and learners face many difficulties in teaching and learning the concept. One of the underlying sources of teaching and learning difficulties of the mole concept identified in literature is the…

This paper is designed to synopsize the efforts of a team of general chemistry teachers to enact assessments during the abrupt transition to online-only instruction and reflect on what was done successfully and what could be improved. The focus is on the extent remote, online assessments accurately measured student knowledge described within the…

After Wesleyan University moved all classes online because of the global outbreak of SARS-CoV-2, the organic chemistry laboratory course adjusted its curriculum to fit the circumstances. A symposium project with several components was introduced, allowing students to develop their scientific writing, presentation, and critical thinking skills…
