Its environment is excellent, but I need more than some strategies for grouping students. In some semesters, the professors ask the students to create their own groups for assignments. The students create their groups based on their geographical, linguistic, and religious categories, and the issue of diversity and inclusion is not considered. Sometimes, intelligent students form their own groups, and the issue of transparency in scoring becomes pale. I suggest the groups should be created by professors, because they know well and can balance their students in good and useful groups.
