Simple but effective strategies for an undergraduate introductory course in signals and systems are described in this paper. These include peer facilitated tutorials, optional class tests, in-class only lab assessment and use of interactive animations. Peer facilitated tutorials were designed to support students to help other students. The optional class tests removed the stress and anxiety students face. With in-class only lab assessment the time students spent writing lab reports was replaced with time devoted to preparing and doing the lab together as a group. The use of interactive animations enabled students to visualise key concepts. Survey results and feedback confirm the positive response and improved student satisfaction.
