The contribution is focused on results of evaluation of activities designed in a framework of European project COMBLAB. The main aim of the project is to design and implement the research based learning materials for students and teaching materials for teachers on the background of Microcomputer-Based Laboratories (MBL).
The subjects of the project interest are Physics, Chemistry and Biology. In conclusion, recognizing the level of students' motivational orientation is needed not only to know the student's interest in performing the MBL activities but also to find out whether the students are competent in filling in the questionnaires used to evaluate the activity tasks.
We found out that mainly initial motivational orientations strongly depend on particular school attended by a student and only weakly depend on gender. The most of the students reported that they understood the activities.
However, after deeper investigation diverse level of understanding was confirmed.
