Atomic Physics in Upper Secondary School: Layers of Conceptions in Induvidual Cognitive Structure
(abstract and paper still missing)
A learning pathway in high-school level quantum atomic physics
In this paper, one student's learning process in a course on quantum atomic physics in grade 13 of a German gymnasium (secondary school) is described. The course lasted 16 weeks for a total of approximately 80 lessons. The aim of the present study is to elaborate the student's cognitive system for atomic physics as a hypothetical pragmatic model to describe, analyse and explain his thinking and learning sequence of several meta-stable conceptions of the atom, starting from a planetary model.

Teaching quantum atomic physics in college and research results about a learning pathway
Our approach is centered around the concepts of "state" and "orbital". Its primary aim is to explain and calculate phenomena and basic facts like size, spectra and energies of different atoms, molecules and solids. Our approach makes use of the analogy with standing waves and uses model building with the computer (STELLA) to avoid high mathematical difficulties.
