The general hypothesis that was examined is: The Matador multimedia program can be improved as concerns the presentational formats both for pupils who are helped by and attracted by visual information and – in particular – for pupils who are helped by and attracted by verbal information. A minor user’s test with 10-15 year old pupils was carried out in order to complement the pre-analysis by testing some specific details of the program with users.
