An active learning design project for a junior-level kinematics and dynamics class

This paper describes a design and modeling experience that was added to a junior-level, mechanical engineering class (Kinematics and Dynamics). Students were tasked to design, build, model and demonstrate an apparatus that met the following criteria: (1) demonstrated one or more concepts developed in class; (2) had one or more attributes that could be varied; (3) took into account all parameters (intended and unintended) affecting the apparatus output, and (4) would be interesting to students 14 years of age and older. The last requirement ensured that the projects could be demonstrated meaningfully to high school groups visiting our campus. Students completed individual, post-project questionnaires, and reported that their understanding of concepts such as friction, impact, momentum, and projectile motion was enhanced as they constructed and tested their devices. Furthermore, most now understand that "real-world" problems often cannot be solved through the simple application of the analytical approaches presented in their textbooks.
