Exploratory data analysis of an european teacher training course on modelling
Résumé
The European project LEMA experimented a teacher training course on modelling in four different countries. We present here an exploratory analysis to evaluate the effect of the training course. From the teachers' answers to a questionnaire on beliefs before the beginning of the training course, the teachers are split in different clusters. With the answers to the questionnaire after the training course, we observe how in every cluster the answers change. We will show how the national groups can be taken into account. Then we will point to questions and challenges related to comparative studies.
