Starting from difficulties that students of education display when they interpret empirical findings and generate scientific arguments, a problem-based e-learning environment was developed. Based on first evaluation data, an elaboration tool was integrated into the learning environment. The tool consisted of a modelling and an explanation part. In…

Mammo I and Mammo II are two versions of a computer simulation based upon scientific problems surrounding the finds of carcasses of the Wooly Mammoth in Siberia. The simulation program consists of two parts: the data base and program logic. The purpose of the data pieces is to provide data of an informative nature and to enable problem solvers to…

A set of computer implemented models are presented which can assist in developing problem solving strategies. The three levels of expertise which are covered are beginners (those who have completed at least one university physics course), intermediates (university level physics majors in their third year of study), and professionals (university…
