IV. Assessment Log of Recent Changes and Improvements. This section contains a running account of course improvements, including the motivation for the changes. No changes made to standard syllabus. Recommendations are below. Part A. Improvements and Recommendations this Semester. Provide a description of course improvements that have occurred this semester relative to those of previous semester (including the motivation for these changes), and recommended changes for upcoming semesters as needed. We recommend that the Op-Amp section of 59:008 be removed from this course and added to the instrumentation course. The op-amps are an instrumentation topic and better taught there. Further, it is not possible to do a good job with the op-amp material due to limited time constraints. Teaching only the ideal op-amp material does not give the students an adequate perspective on these devices, and can be misleading. For example, the important considerations in biasing these devices are not discussed at all and without that understanding, students will not be able to develop functional op-amp designs. Part B.
