For example, such a tool may be used to compare the performance ofexperimental and control groups by recording pre- and post-instruction performance. Eric Mazurin his Peer Instruction guide (Mazur, 1997) used the Force Concept Inventory to assess studentlearning in his introductory physics for both experimental and control group settings byrecording pre- and post-instruction performance.

requirement of full-time status (12+ credits in fall/spring) became problematic for students whoneeded fewer than 12 credits in their last semester to graduate. Other students had scheduling challenges(e.g., 15 credits in one semester but 11 in the other), that threatened their eligibility. In Flit-GAP, after thefirst semester, the requirement for full-time status is interpreted to allow for these cases in which studentsare making progress toward graduation but cannot register for 12 credits in a particular semester .Common Program ActivitiesFlit-GAP provides positive, peer group cohorts for junior, senior, and eventually graduate-level students.Student development and support activities combine social and educational events to help these

A good program is one that controls a process andcan be maintained. The engineer is not the one most responsible in the long run for the successof the process. That is the responsibility of the maintenance team and process and instrumentengineering staff.The syllabus of the earlier Electrical Engineering Course is included in Appendix I.
