Redox reaction is a core concept in teaching and learning chemistry. This article explores a new method for balancing organic redox reactions that requires the balancing of both atoms and charges. The H+, O, H[subscript 2]O, and e- are used as balanced vehicles in two half reactions. A non-oxidation number approach can be applied to both molecular…

Representation plays an important role in helping students understand chemistry learning. This is due to the many chemical concepts that require visualization. Representation is something that still needs to be studied. So this study aims to see the development of representation research in chemistry education. The articles used in this study are…

Previous research suggests that the use of metaphors in science education have both possibilities and challenges. In this study, we analyse the role of metaphors in meaning-making in the upper primary science classroom. We investigate the potential of metaphors about nutrient uptake occurring in classrooms in which an animation was used. To…

When learning about the particulate nature of matter (PNM), students tend to attribute the same properties to both particles and to the substances they compose. It has been argued that this might be explained by them categorizing the wrong ontological category. To explain the relationships between submicroscopic and macroscopic levels of matter,…

Developing a deeper understanding of scientific concepts is one of the primary goals of science education. To improve students' conceptual understanding, it is necessary to explore the major characteristics of their learning process. Informed by previous work on conceptual understanding, this study focuses on the concept of evaporation, exploring…

Achieving knowledge integration for deep learning requires students to develop well-connected knowledge structures through the central idea of a concept. However, a number of studies on student learning in momentum have revealed persistent difficulties in understanding its fundamental concept, particularly in relating net force, time, and change…

Learning progressions (LPs) are descriptions of successively more sophisticated ways of thinking about an idea over an extended period of time. The growing interest of researchers in learning progressions is grounded in the potential it holds to align curriculum, instruction, and assessment. Previous review of research on LPs by Duschl et al.…

In STEM education, the engineering design process serves as a pedagogical strategy to connect science and mathematics concepts. While STEM approaches are increasingly favored in science courses, the role of mathematics in integrated STEM activities is often overlooked, despite its foundational importance across STEM disciplines. This manuscript…

Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I (GCI), reintroduced in Organic Chemistry I (OCI), and then utilized throughout other higher-level chemistry courses. Student difficulties with resonance are well documented. Instruction is one potential source of student difficulties. What instructors…

Virtual Reality (VR) has been widely adopted in educational research; however, its implementation in the classroom is still not as well known as in the research field. In other words, there is a gap between researchers and practitioners regarding the pedagogical issue. This study aimed to explore how VR could be applied in science classrooms using…

The teaching and learning of chemistry can be challenging due to the complex and abstract nature of the subject matter. Traditional methods of instruction often struggle to engage students and facilitate an understanding of essential chemical concepts. To address this, an innovative card game, "Compound Chain", was developed and…

Research shows that when students use core concepts to guide their reasoning, they are able to construct more accurate, mechanistic explanations. However, there is scant research exploring student's perceptions of the usefulness of core concepts. Knowing students' perceptions could be influential in encouraging faculty to adopt core concept…

Students often fail to utilize what they know about one topic (e.g., hemodynamics) when attempting to master another topic involving a similar phenomenon (e.g., airflow in airways). What accounts for this difficulty that students have? And how can students be assisted in doing a better job of applying what they already know to new topics? The…

Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…
