Ask the instructor to write key information on the board, on an overhead or to post it on their home pages. Suggest that your instructor establish an email class list to discuss class information if they have not already done this. This lets you communicate with your classmates on a regular basis and provides you another channel to ask questions. Form a study group to discuss class material. You need to do something quickly to avoid forgetting important information.
Students helping other students learn is a very effective study technique.
Don't tolerate an unsatisfactory learning situation. The first step is to go to your instructor and describe the difficulties you are having. Most instructors care about their students and want them to learn. MU undergraduates are strong students, but a subject can be difficult because of unfamiliar ideas, vocabulary or teaching styles. Take a proactive stance if you experience a challenging subject.
