Clearly defining and clarifying crosscutting concepts (CCCs) helps students to apply them as thinking tools or lenses to understand disciplinary core ideas and science and engineering practices. This study identified three characteristics of the sub-concepts of CCCs: conceptual, superordinate, and common across disciplines, and explored a way…

Teaching science concepts for conceptual understanding has its challenges. Bringing about conceptual change in the science classroom can be difficult because most concepts are complicated and often counter-intuitive in the teaching and learning of science concepts. A review of the literature indicates that the conceptual change model, CCM can be…

Physics Education Research has a rich history of identifying common student ideas about specific physics topics. In the context of electric circuits, existing research on students' ideas has primarily focused on misconceptions, misunderstandings, and difficulties. In this paper, we take a resource-oriented approach to identifying common student…

This research aimed to explore the conceptual structure of chemical equilibrium in upper-secondary school students using factor analysis. Research on chemistry education has shown that chemical equilibrium is an important but difficult-to-understand topic. Exploring the conceptual structure of chemical equilibrium among students will help…

This study investigated the introduction of the second law of thermodynamics using the Legitimation Code Theory (LCT) (semantic waves) among first year chemistry students. The aim of the study was to investigate the extent LTC (semantic waves) reduce the entropy concept's complexity and abstractness when introducing the second law of…

Analogy is a powerful tool for fostering conceptual understanding and transfer in STEM and other fields. Well-constructed analogical comparisons focus attention on the causal-relational structure of STEM concepts, and provide a powerful capability to draw inferences based on a well-understood source domain that can be applied to a novel target…

Natural Selection is prevalent throughout life science learning standards across K-12 contexts. Additionally, undergraduates who are interested in the fields of biology and education must also be well informed on the topic, as it is foundational to some biology research and necessary to touch upon within elementary and secondary classrooms. This…

Visualization can be a motivating way to teach students about molecules. Nowadays, the available experimental data and accurate computational results allow students to build realistic and accurate molecular models. These models include the representation of complex systems such as proteins, membranes, or nanotubes. However, the visualization of…

It is imperative that a profound transformation be carried out in the traditional way in which we teach science subjects, so it is necessary that the role of student change from being a mere recipient of information to being the main player in the construction of his knowledge. One of the strategies to achieve this is to make use of ICT, within…

Logarithms are notorious for being a difficult concept to understand and teach. Research suggests that learners can be supported in understanding logarithms by making connections between mathematics and science concepts such as pH. This study investigated how an integrated chemistry and mathematics lesson impacted 29 teachers' understanding of the…

Fostering methods that promote learners' conceptual understanding is crucial for better performance in science subjects. This study investigated how teachers of physical sciences perceive the utilization of Concept Cartoons as a formative evaluation tool. Ten Grade 11 teachers selected from secondary schools in the Nelson Mandela Bay district of…

This study examined the effect of mind mapping instructional strategy on students' retention in physics in senior secondary schools. The research is a quasi-experimental design of the pre-test, post-test, non-equivalent and non-randomized 2 X 2 X 3 factorial design. 64 students were sampled for this study out of which 28 formed the experimental…

Developing and communicating evidence-based explanations are regarded as essential skills in 21st-century learning. These skills are central to the process of scientific argumentation. Hence, teachers must adhere to a student-centered pedagogy that cultivates students' understanding and argumentation skills. This study investigated the effects of…

This mixed-methods study was designed to compare the learning gains of seventh-grade students (N = 417) taught a 4-week conceptual change unit on density using either a student-centered, guided inquiry-based approach or a more direct, teacher-centered instructional strategy. Application of a multilevel model to data obtained from the…

A study of transition metals includes studying the physical and chemical properties of first-row d block metals in the Periodic Table. The curriculum on transition metals emphasizes learning the physical and chemical properties and is a lecture-based strategy that is predominately employed by teachers to transfer the knowledge on properties of the…
