Quantum mechanics (QM) has become part of many secondary school curricula. These curricula often do not include the mathematical tools for a formal, mathematical introduction of QM. QM therefore needs to be taught at a more conceptual level, but making secondary school students understand counterintuitive QM concepts without introducing…

Research-based assessments (RBAs) measure how well a course achieves discipline-specific outcomes. Educators can use outcomes from RBAs to guide instructional choices and to request resources to implement and sustain instructional transformations. One challenge for using RBAs, however, is a lack of comparative data, particularly given the skew in…

The aim of this study was to develop a science experimental guidebook for the mainstreamed students with learning disabilities and investigate its effect on their conceptual understanding of physical events. Through case study research methodology, the sample of the study consisted of 12 mainstreamed students with learning disabilities. To collect…

Development of cognitive skills is critical for developing the right conceptual ideas in chemistry. Atomic structure, bonding, and associated properties are taught as parts of high school chemistry courses worldwide. The cumulative build-up of misconceptions about the periodic table is to blame for students' poor performance on atoms and…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

Teachers' pedagogical content knowledge (PCK) has the potential to influence lesson planning, teaching and students' academic performance in science. Since PCK is embodied in lesson planning (as planned PCK), this study employed the multiple-case design to describe in-depth the biology teachers' profiles of planned topic-specific PCK (plTSPCK) for…

Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

This research examines the effectiveness of the STEM Supported Inquiry-Based Learning Approach on the conceptual understanding of 7th graders. In the study, a mixed-method design was adopted. The research was carried out with 64 students studying in a secondary school. The study used a Conceptual Understanding Test (CUT) and an Interview Form as…

The integration of mathematics and science in teaching facilitates student learning, engagement, motivation, problem-solving, critical thinking, and real-life application. Although curriculum integration is theoretically desirable for many educators, what to integrate and how to integrate are often the big questions facing teachers working within…

As health and fitness continue to decline and metabolic risk factors reciprocate with increasing incidence in younger and larger cohorts, the importance of conceptually based university health classes cannot be underestimated. Health classes are plentiful in university course offerings but fewer and fewer institutions require a health-related…

This study presents a conceptual framework for embedding interdisciplinary learning approaches in a postsecondary science program in order to foster interdisciplinary science habits in students. The framework was developed through the lens of a multi-year interdisciplinary postsecondary science program that encompasses a series of courses in which…

In this study, we administered and evaluated circular motion concept question items with a view to developing an inventory suitable for the Ugandan context. Before administering the circular concept items, six physics experts and ten undergraduate physics students carried out the face and content validation. One hundred eighteen undergraduate…

The purpose of this study was to find out the influence of the integration sequence of interactive simulation on the construction of the scientific explanation of buffer solutions. This study was conducted with 30 pre-service science teachers. The control group was randomly assigned to study with lecture first and then interactive simulation-based…

The aim of the study is to investigate the level of understanding of light-related concepts of teacher candidates who took the "Basic Science in Primary School" course in the classroom teaching undergraduate program. This research is a descriptive study. The study group consists of 65 teacher candidates, 51 female, and 14 male studying…

Inspired by existing literature indicating that reading literacy is significantly associated with scientific reasoning and chemistry conceptual understanding, this quasi-experimental study explored the effectiveness of reflective reading of scientific articles on student inquiry performance. A total of 134 10th graders from southern Taiwan were…
