Manufacturing Processes

Jul 2011

Larry Yao is very excited about his subject. He clearly relishes manufacturing processes and enjoys explaining it to his students. In no way does that imply that class is interesting, however. There are no notes to take because everything is projected overhead and the notes are xeroxed for you. Things get a bit monotonous around the 45-minute mark most days. He seems to notice but not object to the fact that his lectures put many students to sleep. He often shows movies in class (ranging from campy but plausible to shockingly bad) and the homework is optional (and not useful at all). The book is completely superfluous. The tests and quizzes are multiple choice and are all recycled from previous years' exams, with a few short-answer questions at the end. These short answer questions have only a single correct answer - demonstrating your mastery of the material is rewarded with no points unless you write the exact, verbatim words that the TA's are looking for. There is a cool field trip and a pair of essays. The essays are literally graded on the frequency with which you include the words "Section XXX.YYY of the engineering ethics code says ZZZ" where section XXX.YYY pertains roughly to ZZZ. Coherence of argument and intelligibility are irrelevant. If you study all the practice tests and quizzes he gives you and memorize every slide of the notes, you will have met nearly every question on the final. By midterms, more than half the class was never showing up. The TA's take roll after the halftime break with a yearbook-style sheet of students' photos. Oddly, after memorizing all the old test questions, you will be able to sound medium-knowledgable about most common manufacturing processes. In my class there was a bloc of loudly-whispering cheaters on all the tests and quizzes. Everyone present, TA's included, was quite aware of this, but no one stopped them. Before the final exam Yao gave a speech about the importance of academic integrity which seemed to surpress them somewhat.

May 2011

Very boring, 3 hour long power point lectures. On a good day, I would stay awake during the entire lecture. On a very good day, I would even be able to focus for an hour. Virtually no work for the class other than keeping up with the lectures (<1 hr a week outside of class), but if you can avoid this class - do it. Chances are if you are reading this you are a junior MechE and this course is required, but if not then make the smart choice and drop this class. Tests are 70% multiple choice/true-false, and 30% short answer.You have 300 pages on notes by the end of the class, and you have to know every word of those 300 pages (including side notes, figures, etc) if you are to even pass. To get an A, you have to read the book (60+ pages of extremely dry reading per lecture) and take some serious notes. But, for minimum effort, find older students and memorize their old tests, since he recycles a lot of questions. Over 30-40% of the midterm and final were recycled questions. I did all the work, knew all the lectures and old tests (except that I didn't read the book) and I still found myself clueless on a large portion of the exam.
