Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

The aim of this study was to investigate whether secondary science teachers had different styles of technology adoption for technology-based assessments (TBAs), and whether teachers with different adoption styles showed different patterns of beliefs, attitudes and intentions regarding TBAs. By combining the variable-centered and person-centered…

In upper-secondary chemistry education, the concept of 'Amount of Substance' occupies a central position within the computation framework. However, comprehending this concept often poses a challenge for students. To address this issue, our study aimed to design and implement a computation skills test to assess the varying levels of students'…

The purpose of this study is to examine how students may hold coexisting and competing conceptual ideas and how students' uses of such ideas may evolve during the process of conceptual change by combining two complementary methods including model analysis and the conceptual framework model of knowledge integration. Conceptual change is fundamental…

Purpose: This paper explores the potential of students' participation in the HW educational intervention programme based on participatory methodologies in promoting their environmental citizenship. Design/methodology/approach: Using a quasi-experimental design, 126 students were randomly assigned to the intervention and control groups and filled…

In this paper we present a simple dimensional analysis exercise that allows us to derive the equation for the Hawking temperature of a black hole. The exercise is intended for high school students, and it is developed from a chapter of Stephen Hawking's bestseller "A Brief History of Time."

Easy and visually appealing demonstrations are precious tools for introducing students to the study of enzymes. However, they most often involve purified enzymes and dedicated techniques. Here, we propose a set of demonstrations, which require only fresh horseradish root and consumer chemicals, to help support biochemistry and enzymology courses…

Educators often seek methodologies that enhance enduring knowledge for their students if their goal is to teach effectively. Students who strive to improve their own learning often use less effective study strategies as a way to improve long-term memory or content transfer. If the goal of education is to teach students how to retrieve information…

In 2015, "NFPA 45, Standard on Fire Protection for Laboratories Using Chemicals," from the National Fire Protection Association (NFPA) was updated to include language requiring educators to perform a documented risk assessment when conducting demonstrations in K-12 classrooms. Additionally, in the past five years numerous organizations…

Students experience problems related to low learning motivation, causing their mathematics learning outcomes to become low. The purpose of this study was to determine the relationship between learning motivation and learning outcomes on mathematics subjects in XII science class senior high school 4 Bone. The subjects in this study were 30 students…

Since the viscous behaviour of liquids is evident in many everyday situations, it is plausible to assume that students have (pre-)conceptions about the physics behind these phenomena. As yet, no reliable studies exist on this topic. Therefore, the present study aims to address this research gap by exploring secondary school students' conceptions…

One of the main topics of elementary physics is the idea that every material is composed of "little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one other." These particles could be atoms or molecules. Atoms are the smallest part into…

Given the great interest that black holes arouse among non-specialists, it is important to analyse misconceptions related to them. According to the author, the most common misconceptions are that: (1) black holes are formed from stellar collapse; (2) they are very massive; (3) they are very dense; (4) their gravity absorbs everything; and (5) they…

This study investigated the role of interactivity on the protégé effect, and explored how biology teachers can utilize it in their classrooms to reduce rote learning and facilitate long-term retention. This investigation utilized the generative learning theory, and adopted a non-equivalent quasi- experimental research design involving 60 students.…

A lack of academic and social readiness limits the successful transition to high school and college for many students from populations historically underrepresented in Science, Technology, Engineering, and Math (STEM) and historically underrepresented groups in biomedical careers (HUG). Also, many families from underrepresented groups share little…
