On the first day of school, Mr. Haddad told his 9th grade classes, "You are in high school and old enough to know right from wrong. As long as you behave, we can have a lot of fun in this class. I plan to allow many opportunities for interaction and games. I don't have a list of rules, but I do expect that you will behave yourselves. If you have any questions about how to behave, just raise your hands now and I'll answer questions." (Pauses for awhile.) "OK, let's get started looking at our course. I will hand out my course description and go over my grading criteria and course requirements." A potential difficulty with Mr. Haddad's beginning is that
a. he has no expectations for student behavior or class proceduresb. he should not question students on the first day.c. appropriate behavior in important areas may not be adequately understood by the students.d. b and c only.e. a, b, and c are all correct.
