Some seemed to have fun in group. I think they use the language better. No dramatic improvement by all students. Less fear, minimizes misunderstandings, increases camaraderie. I observed gains, but it is hard for me to distinguish gains as a result of group work, use of technology, projects.
Students discuss mathematics with each other.
It is not their attitude towards mathematics but their attitude toward each other that changes. They learn to use each other as sounding boards and resources. They are better thinkers. Willing to try harder problems, don t mind making mistakes. They liked the course.
