Testing a causal model for learning in a problem-based curriculum.

The aim of this study was to identify the relationship between elements that are important for the tutorial group process and the individual learning process in a problem-based curriculum. The variables under investigation were student-generated learning issues, individual learning process, reporting in the tutorial group, and achievement.A questionnaire containing 22 items was developed. Data were collected in the first year (N = 195) of the Medical School of the Maastricht University in the Netherlands during the academic year 1997-1998. The data were analysed using a structural modelling approach. The results indicate that the model fitted the data well. The path coefficients were moderately high, particular between the explanation-oriented approach and the depth of the reporting in the tutorial group. High path coefficients were also found between the depth of the reporting and achievement. In sum, the model gives insight into how important variables are related and it is recommended that data should be collected to test the model repeatedly.
