Create activities and research goals that require the students to analyze their own teaching methods and then put them to the test. For example, one long-term assignment could be an in-depth research project on a particular style of teaching that ultimately culminates in the student teaching the class in that particular style. Not only would this give the student a great deal of knowledge concerning the subject, but it also prepare her for teaching a course.
Portfolios are a powerful tool in the organization of a teaching course. These consist of student work completed during the course of the semester, including papers, reaction essays, lesson plans and other materials. At the end of the course, this document allows you to give the student feedback, but also serves as a handy guide for the student to use when she begins teaching.
Plan a semester-long project, where students create a multi-tiered lesson plan spanning several different subject areas. Have students present the information to the class along with several projects prepared for the class to do. This activity can serve as a final, as it will test their knowledge of their chosen subject matter and also provide them with assignments and coursework for the future.
Lastly, plan your teaching course around a collective, community-oriented classroom that encourages discussion and not just lecturing. This important, but sometimes neglected, step will encourage collaboration between your students, so that they can learn from each other in addition to your expertise. You may want to include several group projects over the course of the semester so that students have an opportunity to work closely with one another on a variety of topics. These should also be presented to the class, so that everyone benefits from the research.
