(The scheme may also be viewed as filtering the returnsignal with a matched filter, but the convolution of the signal with the impulse response of thematched filter may be harder for students, especially those who have studied neither linearsystems nor digital filters, to grasp.)A computer simulation of the cross-correlation detection process was originally assigned as agraphical programming project in a computer software class. The simple model used in theassignment assumed a sinusoidal signal of adjustable duration as the transmitted pulse and adelayed

In this next section, I describe instructional methods for supportingthe learning of those causal attributes. There are three classes of methods that may be used toenhance causal learning: direct instruction that conveys causal relationships, exploring causalrelationships in simulations, and learner modeling of causal relationships. No direct comparisonsof these methods have been made.Conveying Causal RelationshipsA potentially effective

Because of the difficulty in performing three dimensional analysis, projects focused onkinematic analysis of linkages and numerical solutions of differential equations. This alsoexposed students to numerical analysis tools that are not present elsewhere in the curriculum.Recently, we have decided to include a full three-dimensional simulation as a final class project.During the final week of the course, we cover gyroscopic motion. This is a very difficultconcept for most students to grasp, and simple instructor demonstrations don’t allow the studentsto actually feel the gyroscopic moments. To help remedy this situation and hopefully
