Enter the class key: wsu 7036 9503 After you create an account, you will be able to log in. Homework is due by 11 am of the following class period: Problem Set #1 is due by 11 am Wednesday Problem Set #2 is due by 11 am Friday Problem Set #3 is due by 11 am Monday etc. Learning outcomes: Familiarization with physics and ability to solve problems. 1
How to be successful in this course: (1) Attend lecture. (2) Get hard copies of the lecture slides and write on them during lecture. (3) Do homework problems (using pencil and paper) with a goal toward understanding, not getting a high score. (4) Do additional problems provided in Physics: A Problem Solving Approach. (5) Do the practice problems (provided before each exam). Grading: Laboratory work 25% Homework 5% One-hour exams (best 3 of 4) 50% Final exam 20% Letter grades: 90-100 A-/A 78-89 B-/B/B+ 60-77 C-/C/C+ <60 D/F Usually, the median is at the B-/C+ border. There is no curve, but I reserve the right to change the letter grade scale. If you believe a grader made a mistake, then put a statement in writing and give it to me. We may deduct points if the grader made a mistake in your favor. Midterm grades are advisory and do not appear on the student s permanent record, the WSU transcript. For this class, the midterm grade will simply be based your score on the first one-hour exam. Exam seating chart: Everyone will have an assigned seat for the exams. It is your responsibility to sit in the correct seat. Let me know if you would like a different seat, or if you will be taking tests at the Access Center. One-hour exams: The four 50-minute exams, in class, will start at 11:10 and will end at noon. Bring your own pencils, calculators, and brain. No notes, books, accessing the internet, or any other source of information, during any exam. Your lowest exam score will be dropped. There are no make-up or early exams, even in cases of illness, disability, or emergencies. This is not intended to punish students we just do not have enough personnel to proctor four make-up exams. If you miss one exam, it will simply count as the score that is dropped. In the past, I have allowed students on an official WSU trip to take a test during their trip. The test must be proctored by an official WSU person. Students must arrange for this well ahead of time. There is no guarantee that I will be able to accommodate such a request. Exam reviews: I will discuss the solutions to practice problems, which are posted on the web. You should try to do these practice problems yourself, prior to the review. Final exam: Comprehensive three-hour exam, in classroom. No early exams. The final exam will be from 3:10 to 6:10 PM, Thursday, Dec. 17, in Webster 16. Laboratory: Attendance in the laboratory is mandatory. Deficient performance (defined as less than 50%) in the laboratory will result in a failing grade for the entire course. For details on laboratory grading refer to the Physics Lab Syllabus in the lab manual. The Physics 101, 201, and 202 laboratories will begin meeting the first week of classes, the week of August 24. Lab 2
manuals will be distributed during the first lab session. The last regular laboratory exercises will be performed the week of November 30, the week before Closed Week. All laboratory work must be completed and submitted before 5 PM the Monday of Closed Week, December 7. The lab exam will be administered during Closed Week, during your regular lab session. I am not involved in the lab portion of this course. Questions about labs or enrollment? Contact Dr. Steve Langford, physlabs@wsu.edu. Conduct: Academic dishonesty, including all forms of cheating, plagiarism, and fabrication, is prohibited [WAC 504-26-010(3)]. The instructor reserves the right to take appropriate action. A failing grade in the class may result. Incidents of academic dishonesty will be referred to the Office of Student Standards and Accountability. Disruptions such as lateness, reading newspapers, talking, texting, cell phones ringing, sighing, belching, rolling your eyes, etc., will not be tolerated. If I can hear you talking to someone, you re too loud. No laptops or other devices. Students are responsible for all information given in lectures. Disability Accommodations: Reasonable accommodations are available for students with documented disabilities. If you have a disability and need accommodations to fully participate in the lecture or lab, call or visit the Access Center in the Washington Building, Room 217 (Phone: 335-3417, E-mail: Access.Center@wsu.edu, URL: accesscenter.wsu.edu) to schedule an appointment with an Access Advisor. All accommodations must be approved through the Access Center. Notify both your lecture instructor and the lab director during the first week of lecture concerning any approved accommodations. Late notification may cause the requested accommodations to be unavailable. About the instructor: Professor McCluskey is Chair of the Department of Physics and Astronomy and has been at WSU since the (Bill) Clinton administration. This is his fifth time teaching Physics 101. Prof. McCluskey s research interests include semiconductor physics, highpressure physics, and optics. He has authored two textbooks (Dopants and Defects in Semiconductors, with Eugene Haller, and Physics: A Problem Solving Approach) and one novel (The Last Weapon). Hobbies include skiing, running, and cat training. 3
Frequently asked questions (FAQs): Q: What is the best way to study for exams? A: Do lots of problems and understand how to solve them on your own. Review problems sets, do problems in the text, solve problems presented in lectures, and do the exam review problems posted on the physics web site. Q: Will this be on the test? A: Well now it will be! Seriously, the syllabus tells you which lectures will be covered on the exams. Note that the problem set numbers approximately correspond to the lecture numbers. For example, Problem Set #4 is on material covered in Lecture 4. Q: Do you grade on a curve? A: No. But ususally, the median grade is at the B-/C+ borderline. Q: Is the final exam comprehensive? A: Yes. C mon, I already told you that on the previous page. Q: Does 101 mean easy? A: In some departments, yes. In physics, no. Q: I have a question about labs. A: I know nothing! Please contact the lab director at physlabs@wsu.edu. Q: I am having trouble enrolling for this course. A: I know nothing! Please contact the lab director at physlabs@wsu.edu 4
