Though editorially we must add that we wonder what kind of message students get if they feel their presence in class is not important. Small group work and guest speakers can be used as a course management tool. Give examples of the real world. Discussions teach ways of expressing ideas. We would like a college-wide statement that students are expected to attend class.
Group work happens in class.
The classroom is an excellent place to practice good communication skills. Instructors should be covering things that are not in the textbook. Not coming to class is disrespectful. Expressing thoughts aloud during class discussion helps students learn. Students cannot learn what's taught in class if they are not there.
