When a group wants help, the waste paper basket in its room is put outside the door in the corridor. This makes it easy for the teachers to identify which groups want help. Most of the exercises for the groups are taken from textbooks. Other problems which take less than two hours may be set. In our biggest courses, Basic Mathematics and Basic Statistics, we have at present 300 students and 50 groups.
Students can choose between two alternative times to meet in groups.
Experience from courses in mathematics and statistics, suggests that one teacher cannot manage to help more than 7 groups within a given two hour period. If more groups are needed, additional teachers are required. We ask advanced students to do this teaching because they communicate well with the groups. We let students decide who will be in their group, but we encourage students to stay together if they have worked well together in previous courses. The best size for a student group is between 5 and 8.
