Just In Time Teaching: Potential Uses In Mechanics Courses

Over the last 8 years, the physics educational community has developed a new learning strategy known as Just-in-Time Teaching (JiTT). In this approach, students are required to answer short questions posted on the web at least two hours before class. Questions are typically more openended and conceptual rather than mathematical. The instructor then reads through the student answers before class and tailors the classroom experience based on student understanding. For new topics, many students will appreciate some aspects of the idea, but different students will grasp different aspects of the subject matter. By presenting the answers from different students the instructor can build up an understanding of the complex idea. In this way, students feel greater ownership of the course, come better prepared to class, and have more productive interactions with the professor. Examples of the use JiTT in undergraduate physics will be presented and a framework for applying the techniques to Mechanics described.
