Creative learning is discussed with respect to a specific physics topic. A teaching example, based on an apparatus that demonstrates the standard dynamo model of geomagnetism, is presented. It features many of the basic physics concepts within the syllabus of electromagnetism at high-school and university. To stimulate conceptual learning and to…

Students receive a more complete conception of scientific cognition methods if they reproduce fundamentally important historical investigations on their own. Ohm's investigation realized in 1826 is one of these. This paper presents a simple and accessible experimental unit, in which Ohm's ideas are implemented with the help of modern…

We are developing a new activity-based unit on global warming and the environment as part of the "Explorations in Physics Curriculum." We describe the current status of this unit, which focuses on helping students understand the greenhouse effect and its relationship to global warming. We outline several problems encountered in testing the unit…
