教学方法( Teaching & Learning Methods )
1 Detailed lecture notes are available on the web (for viewing and/or downloading). You should download a copy of these and bring them with you to lecture.
2 Preparation and participation will be important for learning the material. You will be responsible for studying the notes prior to each lecture. Several reading assignments will be given to help promote this activity (1/3 of participation grade).
3 Several active learning techniques will be applied on a regular basis (turn-to-your-partner exercises, muddiest part of the lecture, and ungraded concept quizzes). We will make extensive use of the PRS system (2/3 of participation grade).
4 Homework problems will be assigned (approximately one hour of homework per lecture hour).
Concept Questions
Multiple choice questions posed to students throughout the lecture session. Students register a response using a Personal Response System ("PRS") transmitter. Questions are typically designed to evaluate conceptual understanding, and to be completed in 1-5 minutes. Faculty can see the class' results immediately.
Muddy Points
Responses to "Muddiest Part of the Lecture" cards. At the end of each lecture, students are asked to spend 5 minutes thinking about which of the topics presented was least clear. They write them on index cards and submit them as they leave. Faculty review and respond to "Muddy Points" in the next lecture and/or online.
Readings
Reading assignments for the lecture. These may be from published textbooks, or linked resources. The instructor's notes are assigned as readings to be completed before the lecture, so they are linked in this column. Optional readings appear in parentheses, e.g., sec. 1.1-1.4, (1.5).

评分方法: (Assessment method)
There will be two quizzes during the term plus a final exam. The homework (including reading assignments) will count 10%, the quizzes will count 5% each, and the final exam will count 70%. The instructor reserves the right to alter the percentages slightly, depending on circumstances.
Homework assignments will be due at the beginning of class a week after they are assigned. Any unexcused late assignments will receive zero credit. The remaining 5% of the grade will be based on student performance in various exercises and experiments (many of which will occur in class, including answering questions verbally in class or taking concept quizzes). In all cases the lowest 5% of the scores can be dropped to provide some flexibility for missed classes, etc. There will be no make-up opportunities granted for missing these activities.
