These are:• A hands-on exercise in Matlab, Simulink or Excel should be included as part of class sessions.• Attempts should be made to have the exercise done BEFORE the material is explained. In this way, these were used to motivate the material rather than demonstrate the material after the fact.• Frequent opportunities for questions, discussions and interactions on the material should be

Page 14.175.7As seen in Table 3 above, at Drexel University, the ECE curriculum provides a certain level offlexibility in the selection of courses to fulfill B.Sc requirements. This table reflects the five yearversion which is taken by the majority of students. With respect to where the emulator fits, onefinds a few options: a) as an experimental component module of the sequence of lab courses thatrun from Years 3-5; b) as an experimental module within one of two junior (Year 4) level powerengineering courses called ECEP354 Energy Management Systems and c) as a experimentalmodule within the second quarter of the three course sequence in Power Systems (ECEP401, 402and 403) offered to all power engineering majors.

Laboratory exercises were particularly in need of revision. Wemaintain our overall course objectives while taking advantage of some of the additional I/Ofeatures we have on our homemade boards.
