ConclusionsAs can be seen from the typical examples given in the preceding sections, MatLab canplay a significant role in numerous Electrical Engineering Courses to arrive at answers tosometimes difficult problems in a minimum amount of time. Since MatLab is used inthousands of companies around the world, it not only gives students

Students tracktheir walking activity and caloric expenditure on a daily basis and work on chronicling theirprogress and programming improvement of their pre-course fitness measurements.ProceduresPre-program orientation Prior to the commencement of the service-learning project, instructors from both ET andHPED programs presented the Tiger Trails project to participating classes. This presentationincluded: a) a detailed description of the project; b) the scope and objectives of the project, c)general areas and specific responsibilities of each participating class; d) benefits for participation 6in the

of theassignments. See Appendix A for examples of the pre-lab and post-lab quizzes, Appendix B foran example of a complete lab handout and Appendix C for a grading rubric for the lab resultscomponent. The following diagram details the three lab assignment components. Figure 1- Lab Assignment ComponentsThe dependent variable Prelab #1 was used to check for pre-treatment differences in the twogroups. Each of the aforementioned evaluation instruments were used to address the firstresearch question regarding the effect of cooperative learning on student success in thelaboratory. Dependent variables Prelab #2, Prelab #3, and Project Prelab served as measures ofpre-lab performance. Dependent variables Postlab #1
