Wishing to save valuable class time, some faculty choose not to return exams in class or to discuss them thoroughly in class. It is easy to dismiss this as student responsibility. They also rate faculty members who discuss tests as much more caring and fair than those who do not. Returning and discussing an exam even in a class of 150 can take as little as 15-20 minutes. In fact, it might be most productive to make such a time limit and to make it explicit.
Students are apt to ask fewer non-substantive questions if they know the time is limited.
Misusing Collaborative Learning. Collaborative and cooperative learning groups can encourage students to take responsibility for their own learning, teach critical thinking skills, and increase both learning and retention of conceptual material. Insensitivity to Diversity. In an effort to show sensitivity to diversity, some instructors do the exact opposite. For example, they might ask only the Chicano students in the class to give the point of view of Mexican-Americans, or use the pronoun he to the exclusion of she.
