With total freedom in designing and executing the course, I chose to make it a content-based class on the process of communication. One of the units in the course focused on communication in the classroom environment. Always Usually Sometimes Rarely Never 1. The teacher asked the class questions. Students volunteered to answer the teacher's questions.
Students say their opinions freely in class.
Teachers ask students to express their opinions. Students speak only when the teacher calls on them. Students tell the teacher in class when they don't understand. Students listen quietly when the teacher talks. Students listen quietly when classmates talk.
