BSL PRO Lesson H07: EMG Active Learning This lesson is based on a presentation given by Dr. Jennifer Lundmark and Ms. Andrea Salmi at the HAPS Conference, Maui, HI, June 2-7, 2001 Overview Active Learning Active Learning Lessons convert traditional physiology laboratories into inquiry-based exercises. Students perform a lab exercise designed to encourage them to make observations and develop and test multiple hypotheses during a single lab period using the BIOPAC data acquisition system. These inquiry-based exercises are designed to give students experience with the scientific method, group discussion, design of simple experimental protocols, and the responsibility of making their own decisions. This "Active Learning" lesson allows students to participant in, rather than merely receive, their own education. This lesson assumes students are familiar with the concepts of concentric, eccentric, isometric, and isotonic contractions* and provides only the basic setup and recording steps students need to create their own experiment. Students will design an experiment to measure how electrical activity changes when a muscle contracts with varying degrees of force. To learn more about the benefits of Inquiry-based, Active Learning Labs, read these results from an NSF-CCLI Grant- Supported Project on Inquiry-based labs using the Biopac Student Lab System. * For explanation of these terms and further experimental guidance, review the Appendix . EMG Human skeletal muscle consists of hundreds of individual cylindrically shaped cells (called fibers ) bound together by connective tissue. In the body, these muscles are stimulated to contract by somatic motor nerves that carry signals in the form of nerve impulses from the brain or spinal cord to the skeletal muscles (Fig. 1.1).
