The instructional lab setting has been found to be dominated by prescribed tasks and pre-prepared lab kits. This was explained by teachers' need to guide students to simultaneously progress through a lab curriculum, which prompts them to standardize the lab experience. Nevertheless, prominent professional associations have persistently called to…

We describe the design rationale and structure of a Methods for Teaching Physics course that was redesigned as a project-based learning (PBL) environment, and the entailed learning process it fostered. The projects consisted of the design and teaching of physics lessons with predefined content and pedagogical focus and were structured as a guided…

We suggest an activity for measuring the speed of a bicycle going in circular motion by measuring the bicycle's lean angle. In this activity students will be able to feel the strength that is being activated on their bodies while they are moving in circular motion. They will also understand that it is impossible to ride in a circle without the…

Research indicates that troubleshooting activities that require students to reflect on pre-prepared erroneous examples, i.e. erroneous solutions to problems that correspond to common naïve ideas, impact their learning positively. These include asking students to diagnose erroneous examples; in other words, detect the conceptual errors and then…

In high-school teaching of mechanics, we deal, among other things, with the nature of static and kinetic friction, forces that are proportional to the normal force. Under the influence of frictional forces, a body moves down a rough sloped decline at a fixed rate of acceleration that is independent of its mass. This situation does not apply to…

Creativity can be viewed from different perspectives, such as the creative thinking process, the product, the creative environment and the individual. The physics domain, which is based on experiments, research, hypotheses and thinking outside the box, can serve as an excellent grounding for creativity development. This article focuses on creative…

This study compared students' learning in troubleshooting and problem solving activities. The troubleshooting activities provided students with solutions to conceptual problems in the form of refutation texts; namely, solutions that portray common misconceptions, refute them, and then present the accepted scientific ideas. They required students…

I examined the impact of a self-diagnosis activity on students' conceptual understanding and achievements in physics. This activity requires students to self-diagnose their solutions to problems that they have solved on their own--namely, to identify and explain their errors--and self-score them--that is, assign scores to their solutions--aided by…

Many teachers would agree that not all their A-level students appreciate the beauty of physics or enjoy solving complex problems. In this article, we describe a photo-contest activity aimed at narrowing the gap between physics and students. The photo contest, involving both students and teachers, is guided by the National Center of Physics…

Simple measurements of the decay time of cathodoluminescence are described. Cathodoluminescence is used in many devices, including computer monitors, oscilloscopes, radar displays and television tubes. The experimental setup is simple and easy to build. Two oscilloscopes, a function generator, and a fast photodiode are needed for the experiments.…

Students frequently misconceive the process of problem-solving, expecting the linear process required for solving an exercise, rather than the convoluted search process required to solve a genuine problem. In this paper we present an activity designed to foster in students realization and appreciation of the nature of the problem-solving process,…

Describes and evaluates one assignment from a unit designed to teach basic science concepts and instructional strategies to primary school teachers, specifically, the control of variables. (SK)

Describes the general features of a new, optional learning unit that was developed and implemented in Israel high schools. The unit, which focuses on physics in medical diagnosis, deals with real practical problems and does not replace traditional physics. (JN)

Investigates whether elementary children can compare forces by comparing numbers of weights used in spring and balance problems. Reports that children did not identify weight and force, but they were able to use the ratio between the numbers of weights to compare forces. Suggests some instructional methods based on the findings. (YP)

Examines student teachers' understanding of the concept of force using a two-part written questionnaire. Findings indicate that there is a serious discrepancy between student teachers' understanding of force and the accepted scientific view. Contains 20 references. (JRH)
