Although quantitative measurements in radioactivity teaching and research are only believed to be possible with high technology, early work in this area was fully accomplished with very simple apparatus such as zinc sulphide screens and electroscopes. This article presents an experimental practice using the electroscope, which is a very simple…

This article revisits the cognitive load theory to explore the use of worked examples to teach a selected topic in a higher level undergraduate physics course for distance learners at the School of Distance Education, Universiti Sains Malaysia. With a break of several years from receiving formal education and having only minimum science…

The aim of this study is to lay bare pre-service primary school teachers' perception of "physics" through metaphors. The study was realized with the participation of 38 freshmen pre-service teachers taking General Physics at a public university. Data of the study were obtained with participants filling the blanks in the following…

We demonstrate how students' use of modeling can be examined and assessed using student notebooks collected from an upper-division electronics lab course. The use of models is a ubiquitous practice in undergraduate physics education, but the process of constructing, testing, and refining these models is much less common. We focus our attention on…

The study critically explored the case of Pangasinan learners' physics learning process using culture and language-influenced curriculum materials in physics (CLI-CMP). Case research using cultural historical activity theory (CHAT) designed the study to provide unique ideas on how socio-cultural theory, a recent field of study of Physics Education…

Physics educators generally seek the best approach to make learning process effective for learners. The major objective of this study is to verify the extent of using inquiry-based instructional strategies in higher secondary physics classrooms, and to support the use of inquiry-based instructional strategies to effectively describe the nature of…

This paper reports on a mixed-methods study with high school students. The study focused on the reasons they give with regard to "what they find interesting about their physics lesson" and "what makes them want to study their physics lesson" during a school year. The sample consisted of 219 students, who attended public high…

The aim of this research is to determine the predictive level of physics self-efficacy with regard to physics anxiety and the correlations between the physics anxiety and self-efficacy of pre-service teachers, also to examine whether physics anxiety and self-efficacy beliefs differ depending on pre-service teachers' achievement in physics and…

The quality and standard of South African examination questions for the grade 12 examination have become an important issue for the South African education system. So far, the focus of empirical research has been on factors that lead to poor performance in the Physical sciences as well as the alignment of the grade 12 Physical Sciences examination…

A small ball rolls down from a quarter-circle to a frictionless plane. What will be the magnitude of the normal force when the ball arrives at the tangent point of the circle and the plane? According to the centripetal force formula, the normal force will be 3 "mg" when the curvature radius of the circle is considered, but will be "mg" instead…

Self-assessment is essential to scientific literacy as stated by the National Research Council Committee on Conceptual Framework for the New K-12 Science Education Standards and has since been incorporated into the Next Generation Science Standards. However, little empirical evidence documents which instructional tools are beneficial in improving…

Studies have investigated various aspects of the use of questions in science lessons, but there is still a lack of research that demonstrates how, during peer reflection, teachers learn through identifying and overcoming obstacles to their own questioning in their professional development process. The present study is aimed at analyzing the types…

Many high school classrooms in the United States have physics teachers who are teaching the subject outside their certified content areas because of a severe shortage of physics teachers. There is a critical need to improve the knowledge base of these out-of-field teachers. This comparative case study examined the instructional practice of…

Background: The high rates of attrition in STEM (science, technology, engineering and mathematics) programmes causes concern over a future shortage of graduates entering STEM careers. Students' first year experiences critically affect their motivation and are therefore also critical components of students' academic success in terms of retention,…

As scientific models of student thinking, learning progressions (LPs) have been evaluated in terms of one important, but limited, criterion: fit to empirical data. We argue that LPs are not empirically adequate, largely because they rely on problematic assumptions of theory-like coherence in students' thinking. Through an empirical investigation…
