The most famous equation in physics, E = mc[superscript 2], is rarely introduced in middle school physics curricula. Recent research has shown that teaching Einsteinian concepts at the middle school level is feasible and beneficial. This paper analyses an Einsteinian energy teaching module for Year 8 students (13-14 years old), which encompasses…

Most primary school students, although they grasp the scientific concepts of heat convection at the macroscopic level, commonly fail to visualize those concepts. Therefore, our research aims to enact a constructivist teaching sequence (CTS) to restructure students' visualization changes, ultimately enabling them to synergize macroscopic and…

Some of the online explainer videos for physics present misconceptions as scientifically correct explanations. Even so, some of these videos achieve good ratings on online platforms. A possible reason is that explainer videos with misconceptions foster an "illusion of understanding"--the mistaken belief that a topic has been understood.…

An ability to engage in system thinking is necessary to understand complex problems. While many pre-college students use system modeling tools, there is limited evidence of student reasoning about causal relationships that interact in diverging and converging chains, and how these affect system behavior. A chemistry unit on gas phenomena was…

High school students learn the basic voltaic and electrolytic cell concepts during their last year prior to entering an undergraduate teacher-education science degree. During the 4 years of university, students complete a sequence of topics designed to build on conceptual understanding presented in previous years. At the end of their degrees,…

There has been an ongoing discussion about the role and level of teacher scaffolding in developing student agency while also meeting intended learning outcomes in inquiry-based science classrooms. This study investigates how teachers practice classroom talk to scaffold students' learning through the inquiry process and how teacher authority and…

Positioned in the Hong Kong education context, this article evaluates the effects of teaching science through home and second languages (i.e. Chinese and English) in Secondary 2 (or eighth grade) science classrooms. A total of 479 students, divided into two language instruction groups, participated in a teaching intervention comprising 16 lessons…

Given the importance of cultivating scientific literate societies, the integration of scientific inquiry into school curriculum is key to contemporary science education. It is apparent that textbooks have been an accessible source of science information for teachers and students since the growth of public K-12 schooling worldwide. Textbooks are…

Temperature and heat are difficult concepts for children to grasp due to their abstractness. An image-to-writing approach, guided by the visualisation practices of scientists, was designed to engage elementary students with constructing images to represent their ideas about phenomena and translating these images into text using scientific…

A learning format gaining attention that encourages language acquisition in science is the use of dynamic models as instructional tools. This grounded theory investigates the impact of the dynamic food chain model as an alternative lesson for teaching food chains. The researchers examined the impact of a paper-based activity and a dynamic model…

The Force Concept Inventory is a multiple-choice test and is one of the most popular and most analyzed concept inventories. It is used to investigate student understanding of Newtonian mechanics. A structured approach to data analysis can transform it in a "diagnostic" instrument that can validate inferences about student thinking. In…

The Human Orrery is a representation of the Solar System at a human scale, on which positions of planets over time are symbolized by different discs. Learners can then walk along the orbits of the planets with the right pace. This pedagogical tool uses the principles of enacted cognition to promote a better understanding of the scientific laws of…

The successful transition from high school to tertiary chemistry studies relies on a student's ability to transfer prior understanding since many topics are extended during first year general chemistry. It was therefore of interest to investigate the perspectives of high school and tertiary teachers regarding which topics and concepts they…

The purpose of this study was to investigate the relative effectiveness of experimenting with physical manipulatives alone, virtual manipulatives alone, and virtual preceding physical manipulatives (combination environment) on third-grade students' science achievement and conceptual understanding in the domain of state changes of water, focusing…

This study investigated the effects of teachers' use of "focus questions" on students' knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in…
