Physics problem-solving ability is among the crucial skills physics students require as it enhances their conceptual understanding and develops their abilities for real-world problem-solving. This study employed a descriptive design to investigate the physics problem-solving skills of Senior-Five physics students from Rwandan secondary schools.…

We investigated the effect of short-term teaching (3 weeks) using image analysis on gymnasium/secondary school students' (ISCED3A) skills (science process skills, SPS) and knowledge using Fiji (ImageJ) software. The theoretical teaching was combined with IT-based education (measurement of the area or signal intensity on photos from scientific…

CAEx (Computer-Assisted Experimentation) enables real-time experiments to be carried out using a computer; it includes data acquisition and sensor systems, as well as real-time measurement of numerous physical properties. The use of computer-assisted experimentation in the teaching of physics and chemistry in Moroccan secondary schools underwent…

Effective organic chemistry instruction necessitates an adaptable approach that accommodates varied learning styles and improves students' comprehension of concepts. To attain this goal, teachers may employ visualization, molecular modeling, and interactive software to explain three-dimensional structures and spatial interactions. Thus, the…

Teaching redox reactions requires careful investigation as learners often display a range of misconceptions, particularly in connecting the chemistry levels of representation: macroscopic, sub-microscopic, and symbolic. This study explores teachers' teaching strategies, opportunities, and challenges when developing conceptual understanding of…

A holistic education should nurture a range of skills that are essential for thriving in a fast-changing world, including higher-order thinking skills. These skills are deeply intertwined with knowledge and many in the assessment community agree they should not be assessed in isolation. Curricula structured around long-established subject…

Two-year colleges (TYCs) continue to play a significant role in the physics higher education system. Historically, about one in ten physics bachelor's degree recipients started their postsecondary education at a TYC (Pold & Mulvey, 2025). For the classes of 2021 and 2022, about 13% of all physics bachelors started at TYC (Pold & Mulvey,…

Many high school and first-year university courses include discussion of the magnetic effect of currents. Frequently discussed textbook examples include long, straight wires, circular current loops, and solenoids, partly because these examples are tractable mathematically. The solenoid naturally leads to discussion on magnetic materials since it…

The gender gap remains an issue in the biological education community. This study explores the extent to which an egalitarian gender ideology, encapsulated in five biological science textbooks for upper secondary schools in China, manifests through representational, interactive and compositional meanings of social semiotic theory. The findings…

The way high school chemistry curricula are structured has the potential to convey consequential messages about knowledge and knowing to students and teachers. If a curriculum is built around practicing skills and recalling facts to reach ''correct'' answers, it is unlikely class activities will be seen (by students or the teacher) as…

In this study, it was aimed to examine the visual content and expressions in the texts in the "Cell Divisions" unit in the 10th Grade Biology textbook of the Ministry of National Education, Secondary Science High School, taught in the 2022-2023 academic year, in terms of scientific content. The data sources of the research, in which the…

This paper describes a study in which five physical science teachers were requested to take photographs and describe the science concepts embedded in these. Particularly, the science had to be relevant to the grade 10-grade 12 curriculum they were teaching. This study was an exploratory case study employing qualitative methods. To analyze data…

Science, technology, engineering, and math (STEM) education is of global focus, demanding qualified mathematicians, technologists, engineers, and scientists from diverse settings. Addressing the STEM academic achievement gaps among secondary students from marginalized backgrounds is a central concern and focus addressed in my research because of…

A simple photometric device was built to measure the kinetics of the title reaction. The device consisted of a green light-emitting diode (centered at 520 nm), a sample vial, a photodiode, and an Arduino microcontroller board. These parts were mounted on a black poly(lactic acid) holder which was manufactured by utilizing three-dimensional…

This publication presents a series of experiments in the field of nanomedicine for high school chemistry education and student laboratories, developed as a collaborative project between chemistry didactics and chemical research. In this context, polymeric nanocarriers represent a promising approach for drug delivery, acting as "smart…
