Developing Students' Ideas about Lens Imaging: Teaching Experiments with an Image-Based Approach
Grusche, Sascha
Physics Education, v52 n4 Article 044002 Jul 2017
Lens imaging is a classic topic in physics education. To guide students from their holistic viewpoint to the scientists' analytic viewpoint, an image-based approach to lens imaging has recently been proposed. To study the effect of the image-based approach on undergraduate students' ideas, teaching experiments are performed and evaluated using qualitative content analysis. Some of the students' ideas have not been reported before, namely those related to blurry lens images, and those developed by the proposed teaching approach. To describe learning pathways systematically, a conception-versus-time coordinate system is introduced, specifying how teaching actions help students advance toward a scientific understanding.
