This action research case study explored the ability of three high school chemistry students to grow in their understanding of nature of science (NOS) during its explicit-reflective inclusion in two unit chapters on bonding (ionic compounds followed by covalent molecules). Students completed a pre, post and delayed Views of Nature of Science Form…

This paper presents a perspective of how the radiation and radioactivity themes have been discussed at the high school level in several locations around the world. In this context, scientific journals, academic journals, theses, dissertations, and media materials were analyzed. Recent research has shown that the concern with the discussion about…

The purpose of this study was to delve into the interaction between pre-service chemistry teachers' pedagogical content knowledge (PCK) and content knowledge (CK) while teaching electrochemistry. Two pre-service chemistry teachers enrolled in practice teaching course in chemistry education program participated in the study. All PCK components were…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

Understanding why teachers teach the way they do is important especially in a time of curriculum reforms. Hence, the aim of this research is to unpack the secondary school physical science teachers' beliefs on the purposes and goals of science teaching (PGST) and to check the alignment of their beliefs on PGST with constructivism. A convergent…

The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary…

The purpose of the study was to diagnose students' misconceptions of a number of basic astronomy concepts, namely, the Universe, the Sun, Comets and Constellations. The study was designed as a mixed method research and the sample was composed of a total of 110 seventh grade students. Data were collected through concept cartoons and interviews. In…

Broad misconceptions about global climate change (GCC) could hinder efforts to address this large-scale problem, and curricular materials can play a substantial role in what students learn about GCC. This study examines how U.S. high school textbooks and supplemental curricular materials published between 2007 and 2012 portray the causes,…

Alternative conceptions in astronomy are a road block to new learning. Astronomy content is included in the Australian Curriculum (AC) from Year 3 and then intermittently in Year 5, Year 7 and Year 10. In accepting that science is socio-culturally constructed, it is important for teachers to have a clear understanding of the alternative…

Misconceptions are sometimes called "alternative conceptions" in acknowledgement of the fact that although these concepts are inaccurate, they are congruent with prior experiences. The idea that misconceptions must be addressed to improve learning is helpful to remember when developing a case study. Students will bring their existing…

In the context of what are often highly compartmentalised curriculum requirements, this article considers the cyclical nature of the acquisition and transfer of knowledge in the education system in relation to those questions that transcend individual subjects as set out in traditional curriculum divisions. It also considers the detrimental…

This article argues that what is most at risk in schooling during a global pandemic, or other similar broad challenges to normal functioning, are those elements that might be considered the less traditional and so the most progressive. After setting out some general background common to the challenge faced by schools and school teachers, this…

One of the most powerful strategies to support next generation science instruction is the use of instructional models. The Biological Sciences Curriculum Study 5E (Engage, Explore, Explain, Elaborate, and Evaluate) instructional model is arguably the most widely used version of a learning cycle in today's classrooms. The use of the 5Es as an…

This study aims to investigate the comprehension levels of classroom teacher candidates about the key concepts of Life Science Curriculum. The study was carried out within the qualitative research approach and descriptive survey model was adopted. The sample of study consists of final year 114 classroom teacher candidates who are studying Primary…

Curriculum statements and textbooks are considered to be vital support tools for teachers, particularly during times of curriculum innovation. A recent change in South Africa was the controversial inclusion of evolution in the school curriculum, raising serious concerns amongst biology teachers regarding the adequacy of their content and…
