Things to consider.

i used interactive exercise for my students. There are reason why i used interactive exercise.
First reason is i think communicated classmates is very important. So if i teaching my student
i usuallly get paired and communicate eachother. i think it help my student improce theri
knowledage. Second reason is i try to improve classmate relationships. When they meet first
time they didn`t talk eachother because awkward. So i think when they get paired and start
to eachother it can be help released awkward.
