How can Ms Clare prepare herself for the changes involved in teaching culturally diverse students?
I really agree with you. It is very important that teachers get to know their student and form a good relationship with them. This is a way in which students will respond better to the teacher.
It's a great idea to have students share about their cultures. The teacher will learn more as well as the students.
I believe she should different group activities that can study different cultures and teach and the groups can teach them to the class.
Being aware of the diversity in the classroom is #1.
Teachers can try to make their students get along, but that doesn't always happen.
