Background: There is a growing view that 'Big Ideas of science education' are useful for teaching science but there is not much knowledge of how teachers work with them. Purpose: This study explores the conceptualisation and practice of the use of Big Ideas of science education by primary and secondary teachers in Chile. Sample: A total of 63…

Background: Constructing knowledge through collaborative practical work is a complex process and involves the use of multiple modalities by group members. In practical work sessions, students often manipulate visual objects or textual materials but do not develop their scientific ideas. Purpose: This study illustrates (a) the challenges that…

Background: Photomicrographs are major biological representations which help students understand more about the structures of cells and tissues. Owing to their abstract nature, students often rely on representations in textbooks to develop their understanding of photomicrographs. Purpose: This study investigated how students with low, medium and…

Background: Quantum physics has found its way into upper secondary school physics curricula worldwide. This trend coincides with increased attention for conceptual understanding in physics education in general and quantum physics education in particular. Students' conceptual difficulties of learning quantum physics are regularly reported. Little…

Background: Nanotechnology, a multidisciplinary field with increasing societal importance, demands for an increase in research abilities and capacities. Yet, nanoscience and nanotechnology (NST) are largely inaccessible to K-12 students. This situation demands efforts in research towards bringing NST learning into K-12 classrooms. Purpose: The…

Background: Recent studies have highlighted the application of STEM (Science, Technology, Engineering, and Mathematics) knowledge into daily life via hands-on practical works. The limitations of the existing conventional laboratory work can be potentially overcome by the implementation of the innovative use of smartphones as an experimental tool…

Background: Research on chemistry education has found that students have commonly some difficulties in understanding chemical changes. These difficulties in the learning process have negatively affected students' success. For this reason, it is very important to overcome students' learning difficulties with new materials that prevent the…

Background: Many researchers have investigated student reasoning in Newtonian mechanics. In 1979 Viennot revealed that most students associate the concept of force with the velocity or acceleration of a motion. Forty years later, student understandings remain a major challenge for teachers. The implications of this challenge are still unclear,…

Background: Renewable energy curriculum reflects research, standards, and policy documents that emphasize both environmental literacy and engineering, technology, and science concepts. Students' science achievement in this and other areas have been found to be predicted by their teachers' content knowledge. Therefore, this study examined whether,…

Background: An acronym for 'science, technology, engineering, arts, and mathematics,' STEAM education is an approach that supports the understanding of science content by understanding the skills stimulated by artistic experience. However, only a limited number of experimental studies have investigated the effects of STEAM education on concept…

Background: Being able to think independently is a must for students to construct new knowledge in their minds. Self-explaining is a constructive learning strategy that encourages students to think for themselves and to make inferences that go beyond the given information. The Self-explain--Discuss--Re-explain (SDR) strategy adapted from…

Background: It is a challenging task to teach students who get diagnosed with a specific learning difficulty. Given that they can easily get distracted, they need more support than students without any disability. Accordingly, the use of any instructional technology that could attract their attention might have a positive impact on their learning…

Background: Understanding students' preconceptions is an important initial step towards a successful and meaningful learning in physics. This is more relevant and important especially for concepts that are introduced formally as early as preschool including friction. Visual representation maybe often used as an aid to teaching, however,…

The study provides an insight into how teachers may facilitate students' group learning in science with digital technology, which was examined when Norwegian lower secondary school students engaged in learning concepts of mitosis and meiosis. Quantitative and qualitative analyses of the teacher's assistance draw on Galperin's conceptualisation of…

Background: A multimedia software designed as a Computer-Assisted Scaffolding system was used to teach gas behavior on the submicroscopic level using Physics Education Technology Project (PhET) simulation. PhET is a set of interactive, research-based science and mathematics online simulations (https://phet. colorado.edu/). Purpose: The purpose was…
