Notes:

Lectures: Due to the large amount of material covered in this course, it will not be possible to cover everything in the lecture. The purpose of thelectures will be to illustrate and explain the important and difficult concepts and their application to the solution of problems. In order for the

lectures to have maximum effectiveness, you need to come prepared. The textbook is a valuable resource with examples and concept questions

designed to help you. Therefore, it is essentialthat you read the material in the textand the lecture notes before the lecture.

The lecture will be conducted in the following manner: I will give 10-15 minute mini-lecture on a topic or major concept. I will then work example

problems in which I will discuss problem-solving strategies (15-20 minutes). At the end of each lecture, I will pose a question related to the materialpresented during the lecture in the activity (15-20 minutes).

Lecture Notes: All PowerPoint notes will be posted on the SIUE Blackboard (http://bb.siue.edu). The course ID is PHYS152001-University

Physics-Spring 2010. It is the students responsibility to print out the notes. Always bring the notes with you.

Homework: Homework will be assigned for each chapter. Assigned problems will be posted on SIUE Blackboard. On each assignment, twoproblems (the same for everyone) will be chosen fordetailed grading. All homework assignments must adhere to the following:

1) Your homework must be organized and neat (you may need to use pencil).

2) Write yourname at top of first page.3) Problems should be assembled in sequence and stapled.

4) Indicate your reasoning clearly.

Make-Ups: There will be no make-ups for missed activities, homework, or exams (including the final exam). In case of illness or family crises,

you must provide documentation to support your claim.

Cheating: SIU policies on Academic Dishonesty and Academic Misconduct will be strictly followed.http://www.siue.edu/policies/3c2.shtml

Withdrawals: The University Withdrawal Policy will be strictly followed. http://www.siue.edu/policies/2c1.shtml

Extra Help: You are encouraged to visit the TAs or myself during office hours. TAs office hours will be held in room SL 2328.

Special Accommodations: Students with special needs are encouraged to contact the instructor and/ or Disability Support Services (SSC 1270,

3726) prior to the third week of the course. If official university business requires you to miss a class, please contact the instructor in a timely

fashion. http://www.siue.edu/dss/

Advice:

Physics is hard! This is why I have assigned a lot of homework, activities, and exams. I believe that the best way to learn is to do, and that's why we will do a

lot. All I ask from you is that you give me the best that you can do, and I will do my best to help you along the way.

1. Come to class! I expect regular attendance. If anyone leaves after an activity is given, that person will be given a zero for that activity. If you are toosick to attend class or have to be out of town, just let me know beforehand and I will give you an excused absence; otherwise you will get a zero (0) onany work done on that day. Call the number above and leave a message oremail me.

2. Read the assigned chapters before the first class meeting that week. Read your book carefully! Science is not like history. You cannot read it once andexpect to retain everything that you read. Physics is more than reading a book. Physics is concepts. Concepts allow you to reason logically and that's

what science is -- logic. So read the chapter once (quickly) and then read it again (slowly). Take time to understand the concepts of the chapter.

3. Keep up. Do not cram all the information all at once (the homework and the activities will not allow you to get behind). I have no sympathy for peoplewho fall behind!

4. Come see me if you need help! Either after class, during office hours, or by appointment.

Rules:

1. No cell phones in class (especially picture phones)! TURN THEM OFF!2. Maintain quiet during class. Some students in class are here for a reason. They want to learn! It is extremely rude and disrespectful when people

talk during class.

3. Show up on time.4. Show up on time for exams! If you are late for an exam by a considerable amount of time, you may not get to take the exam. If you arrive before

anyone finishes the exam, you may take the exam. If you arrive after the first person turns in his or hers exam, you will receive a zero on your

exam!

5. If you have any problems with the class, how it is being run, other students bothering you for answers, cheating, problems on grading homework orexams etc.... Come see me immediately. In these matters, come to my office hours or set up an appointment.

6. I reserve the right to add to this list verbally in class.
