Chemical thinking has been widely recognized as a core competence for supporting students' problem solving in chemistry education. Disciplinary essential questions and perspectives are two critical aspects of chemical thinking. This study connects essential questions with such perspectives to develop a new framework for restructuring chemical…

The Fourth Industrial Revolution Chemistry Teachers Effectiveness Scale (4IRCTES) was evaluated in secondary schools in Southwest Nigeria to determine its item discrimination, item parameters, and model-data fit. This study utilised a descriptive survey research design and included 4,986 Chemistry teachers in the southwestern region of Nigeria,…

This research probed the perceptions of secondary school science teachers concerning the objective and utility of assessment, exploring the influences of gender, teaching experience, and specific science subject components. A total of 100 secondary school teachers from Selangor participated in the study, completing the Teacher's Conception of…

Background: Practical work in school science has been ineffective due to students not connecting hands-on to minds-on aspects. With the designation Thinking-Back-and-Forth (TBF)we present a framework with a taxonomy of TBF activities. Purpose: Aim was to gain insight how teachers stimulate and support their students in TBF. Detailed information…

Connecting chemistry educators at the high school and secondary education level with chemistry education researchers in academia has never been more vitally needed, and yet these groups are still frustratingly divided. Structural differences in the way in which secondary educators go about their business, both through the business of being a high…

Systems thinking in chemistry education (STICE) has been proposed as an approach that could better equip students with abilities to connect their chemistry knowledge with other disciplines and with the skills needed to tackle complex global issues. However, educational change in chemistry is a complex effort that involves many interconnected…

This article reports on a study of understanding of key sub-topics of the curricular model of covalent bonding among participants at all levels of the chemical education system in Croatia, including among secondary school students, university students (some of whom are pre-service teachers), and secondary school chemistry teachers. The diagnostic…

Despite years of research and practice inspired by chemistry education research, a recent report shows that US secondary instruction is not aligned with current national reform-based efforts. One means to mitigate this discrepancy is focusing on pedagogical conceptual change, its precursors (higher selfefficacy and pedagogical discontentment), and…

Teaching chemistry as a practice rather than as a mere collection of facts demands that teachers modify their practices, particularly their approach to formative assessment (FA). In this study, we investigated how teachers' FA practices changed as a result of their participation in a professional development program designed with a Chemical…

Culturally Relevant Education (CRE) focuses on the design of curricular materials that strengthen students' cultural identities while teaching classroom content and science practices. While examples of CRE in science continue to grow, the identities and cultures of the designers are often different from those of the students and communities in…

In this paper, chemistry teachers' reactions/behavior or actions following students' undesired, unexpected or incorrect responses/answers to the posed teacher oral questions are reported. This study which was carried out in Tanzania in Iringa Municipality involved three chemistry teachers teaching in three different secondary schools. Actual…

Background: Digital simulations are emerging technologies in science education that allow students to visualise abstract concepts and enable science teachers to conduct laboratory work/experiments online. Objective: To determine teacher readiness, the study focused on their cognitive skills and knowledge and perceptions of the use of digital…

Background: Although cutting-edge chemistry research can be an interesting and motivating context for students in pre-university education, few characteristics of supportive and effective learning materials based on such contexts are available. Purpose: In this study we investigated the design, implementation, and evaluation of context-based…

In the laboratory, data acquisition systems are important, as they allow us to easily and precisely collect data. In this sense, Arduino emerges as an automatic data acquisition device with great potential, due to its low cost and high versatility. In this work, we describe the development of an experimental apparatus, with automatic data…

During the time of the COVID-19 pandemic, online teaching was implemented by teachers in almost all education areas, and various technological tools were also employed to improve teachers' online teaching effectiveness. Based on this, the current qualitative case study aims to explore chemistry teachers' experience during online teaching in…
