The best aspects of this course included the note packets, the handouts designed so that students can add additional notes, and the organized lectures. One student felt that the course focused too much on theoretical aspects and derivations, and not enough on understanding practical concepts. Another student felt the grading system was “draconian.” Suggestions included providing students with partial credit and better feedback on returned assignments. Prospective students should know that they wil learn a lot in this course, but must be prepared to complete a lot of Excel spreadsheets.

Students overwhelmingly cited the well-organized lectures and structured notes provided by the instructor as the best aspect of the course. The instructor paused during lectures to give students time to complete notes. However, the homework was difficult and often time grades were not returned until much later, leaving many students unsure about their progress. More feedback on homework, clearer expectations regarding exams, and shorter homework assignments were some suggestions for improvement. Prospective students should know that details are more important than large concepts in this class and working together in a group on homework is useful.

Students enjoyed the interesting readings and intimate class size which facilitated relevant group discussion. Students appreciated gaining perspective from other students from diverse majors. Students felt that the readings were difficult and time consuming. Suggestions for improvement included having shorter class periods, assigned readings with a clearer perspective, and writing assignments due the day before so students are able to read classmates’ perspectives. Prospective students are encouraged to prepare for class discussion by thoroughly reading the assigned articles and taking notes on questions and ideas surrounding course topics.
