My co-teacher resorts to harsh measures when it involves disciplining students in our class. She screams and yells all the time and the worst part is that she steps really close to their faces and yells. This approach is totally opposite to mine, I do not believe in raising my voice at all. Even during a call and response, I remind my students that I will only state my directive once. It is the students' responsibility to lower their voices in order to hear me. What bothers me is that she uses this approach even with students who have learning disabilities. Please advise as to how I can convey my thoughts without creating any discord.
