Laboratory experimentation providing students with hands-on experiences can greatly enhance the teaching and learning of physics. However, traditional hands-on laboratories are very expensive, limiting the possibilities for practical activities. In addition, limited time for laboratory practices prevents teachers and students from conducting…

One of the skills needed in the 21st century is critical thinking skills that need to be developed for secondary school students. Currently, upper-secondary students' critical thinking skills are still low. To overcome the problem, websitebased E-module learning media was developed using a STEM approach with a Problem-Based Contextual Learning…

Artificial intelligence (AI) has transformative potential to support the education of students with moderate to severe intellectual disabilities (M/SID) and their teachers. Although research and evidence-based practices (EBPs) are integral to fostering positive student learning outcomes, educators face challenges in effectively implementing these…

The present study explored the learning challenges that African American female students experience in their algebra or biology courses. Existing literature does not fully explore this subject, as studies are often inclusive of all races (i.e., all girls in science, technology, engineering, or math [STEM] fields) or all genders (i.e., all Black…

This study explores teachers' use of Spanish in sixth-grade bilingual science classrooms at an urban middle school in Texas. We used a case study approach to study how two Spanish-English bilingual teachers utilized Spanish during instruction in a unit on space exploration and their beliefs on Spanish use in English-dominant science classrooms.…

In secondary science education, students often do not feel engaged with the scientific concepts that are taught, which hinders conceptual learning. This lack of engagement can be overcome by fictional placemaking. Therefore, the purpose of our design-based research is to explore how the creation and use of fictional places lead to meaningful…

Being lectured by a woman physicist can benefit students' performance, motivation, and engagement with physics. However, due to the severe underrepresentation of women physics faculty, these instances may be scarce. Through semistructured interviews with seven women physics lecturers, we used expectancy-value theory to understand the situative…

This research investigates students' argumentation quality in engineering design thinking. We implemented Learning by Evaluating (LbE) using Adaptive Comparative Judgment (ACJ), where students assess pairs of items to determine the superior one. In ACJ, students provided rationales for their critiques, explaining their selections. Fifteen students…

This study aimed to develop and evaluate a web-based TPACK scaffolding for online learning to enhance the TPACK skills of preservice chemistry teachers. The preliminary study identified the lack of a clear perception of TPACK among preservice chemistry teachers. Therefore, we developed a web-based TPACK scaffolding tool consisting of five menus:…

Course-based undergraduate research experiences (CUREs) have been increasingly incorporated into science, technology, engineering, and mathematics (STEM) curricula, leading to greater inclusion of students in real-world STEM practices. Implicit within the definition of CUREs is the notion that generated research findings will have relevancy to one…

Peer Instruction (PI), a student-centred teaching method, engages students during class through structured, frequent questioning, facilitated by classroom response systems. The central feature of PI is the ConcepTest, a question designed to help resolve student misconceptions around the subject content. Within our coordination chemistry PI…

Science and society are inseparably linked, shaping each other in ways that define our world, emphasizing the need to teach science for empowering students capable of taking meaningful action toward building a sustainable and just society. Developing sustainability competencies in students is an important step toward this goal, with controversial…

A fairly recent paper resolves a large discrepancy in the internal energy utilized to fire a cannon as calculated by two inertial observers. Earth and its small reaction velocity must be considered in the system so that the change in kinetic energy is calculated correctly. This paper uses a car in a similar scenario, but considers the work done by…

Contrary to current IUPAC recommendations, the chemical element X should be defined as the nucleus of the X atom. Consequently, different isotopes with their different nuclei belong to different elements, each one with its own physical and chemical properties. This view leads to the conclusion that we no longer have a periodic table of the…

There are five unique points in a star/planet system where a satellite can be placed whose orbital period is equal to that of the planet. Simple methods for calculating the positions of these points, or at least justifying their existence, are developed.
