I always give my students enough time to answre questions.

I always try to include all my students in class activities.

Lecture and hands on are what the student's respond to.

When I see a student on the phone I ask them to google something pertaining to the course material.

I just stop and say to the student's who are talking that I will wait until they are finished and remind them that this is wasting class time, and usually that is all that it takes.

I like to tell the student the important topics we will be covering the next day at the end of each class so they know they will be in the next day and will not want to miss the material.
