A note on expectations. I expect you to use the assignments as a way to learn about the material. Finally, homework assignments are meant to be completed by individuals, not groups. This is not to say that you cannot work together on homework. This will appear to be a contradiction to some students, so let me attempt to explain the difference.
Individual work requires independent thought.
Likewise, if two students work alone to derive their answers, compare them and find mistakes, and then correct them together, they have both thought about the problem independently so that is ok. On the other hand, a group of students working together to figure out how to work a problem, one person deriving the answer, and then sharing that answer in the group, is not independent work. There are two principles that you should follow when completing your case reports. The first is that you are completing this work in the capacity of an entry-level engineer or a consultant. Therefore, you are trying to give information in the form of analysis to help solve your supervisor s or client s problem.
