This is the fourth paper in our Light-Emitting Diodes series. The series aims to create a systematic library of LED-based materials and to provide readers with the description of experiments and the pedagogical treatment that would help their students construct, test, and apply physics concepts and mathematical relations. The first paper provided…

Project-based learning is a research-based instructional tool that has proven to be effective in all secondary curricular disciplines, particularly in the areas of science, technology, engineering, and mathematics (STEM). A project is an applied activity, often hands-on, where the students are challenged to successfully address a problem. In many…

Demonstrates what theoretical physicists make a rule using juggling. Provides the thinking process and calculating procedure. (YP)

Provides two exercises in abstract problem solving. Intended to parallel a physicist's approach to the solution of a law of nature, the activities are open ended without definite answers. (CP)

Suggests a scientific approach for teaching problem solving that would aim at understanding the underlying cognitive mechanisms responsible for good problem solving and would then use the resulting insights to design explicit instructions for enhancing student's problem solving skills. (Author/SK)

Gives several sample experiment problems for electricity and magnetism. To solve an experiment problem, students have to do one or more of the following: clarify a poorly defined problem, divide a problem into parts, access the appropriate concept needed to solve each problem part, decide whether approximations are appropriate, design an…
