Lecture Instructor's Comments 

Welcome to PHYS 122 — electro-magnetism is one of the most beautiful and useful topics in physics. You are expected to attend all lectures and to come prepared by watching the FlipIt Physics videos and reading the textbook before class. (FlipIt clicker questions will encourage these good habits.) Physics is a lot of work, but it is deeply rewarding to really understand how the world works. We will talk about the best ways to study in class, but in general solving problems is the best way to get a deep understanding of the material. To that end...

Some words on how best to prepare

The best way to deeply understand physics is by solving problems. It is through problems that we move our understanding from general "it kinda works like this…" from the lectures/videos/text to a deep internal understanding of the world works. In addition to the homework assignments you should try to work on as many problems from the end of chapters as you can. In general, be careful of not looking at solutions before REALLY thinking hard about how to solve a particular problem. Spending 30 minutes struggling to solve a problem is much more effective than looking up the answer and following along. Every time somebody solves a problem for you, if you have not really challenged yourself to think hard about this particular problem, you will have missed an opportunity to learn something yourself.

Grading Policy, Exams, etc...

The final course grade is based on contributions from the exams (2 midterms and a final), lab-session grades, tutorial-session grades, lecture-related homework assignments (via WebAssign), FlipIt Physics (pre-lecture questions), clickers in-class questions with relative weights as indicated in the table: Grade weighting:

Midterms & Final (see note) 65%
Lab section 11%
Tutorial section 8%
Lecture HW 8%
FlipItPhysics 4%
Clickers in class 4%

note, the 65% comes from either of the below options, whichever gives you higher grade:

Option 1: count both midterms with each weighing 21.66% and final weighing 21.68% (downweight final)

Option 2: count best of 2 midterm with weight of 21.66% and final weighing 43.34% (drop lowest midterm)


Exams: 

Exam Composition: lecture lab tutorial
Midterms: 68% 12% 20%
Final exam: 60% 20% 20%


There will be Lab-related multiple-choice questions on each midterm exam and on the final exam. There will be one page of hand-graded tutorial questions on each midterm, and multiple-choice questions on the final exam. There will be one page of hand-graded Lecture questions on each midterm exam, plus additional Lecture multiple-choice questions. 55% of each Midterm Exam will consist of multiple-choice questions. The Final Exam is usually entirely multiple-choice. There will be no makeup exams, but the lowest midterm exam score is dropped. You must take both midterms. Each midterm will emphasize recent material, but may include questions dealing with topics from earlier in the course. You are NOT permitted to bring any notes. The exam sheet will contain a page with formulas that I will publish before the exam. Regular calculators are permitted, but graphing calculators are not. Cell phones, radios, etc. are not permitted. Laptop computers are not permitted, and the use of the text-storage capability now available on many calculators is not permitted. Exams are to be your own work; you are not permitted to collaborate with any other person. The Physics department reserves the right to ask for valid identification from any student during examinations. 

Labs: 
The lab section grade is based on scores for all 8 lab activities done in lab section, including pre-lab and post-lab exercises on WebAssign. Students who complete fewer than 6 of the 8 labs, or score less than 60% of the available points for the quarter, will receive a grade of 0.0 for the entire 5-credits! 


Tutorials: 
The tutorial section grade is based on participation in each tutorial session as well as completion of pretests, but the largest portion comes from scores on tutorial homework. 


Note that there will be no make-up exams in PHYS122, and you must take all three exams. Students with outside professional, service, or career commitments (i.e. military service, ROTC, professional conference presentation, NCAA sports, etc.) conflicting exactly with the exam dates must contact the intructor during the first 3 weeks of the quarter to establish alternate examination procedures. Students who miss an exam without making prior arrangements with the lecture instructor will, except for extreme circumstances, receive a final grade of 0.0.
Exam Re-grades: If you believe that the points on the examination were incorrectly totaled or if there is a gross error in the grading, you may return an exam for regrading. To do so, you must resubmit the examination within 2 working days after the exams are returned. You must write a brief note on the front page or attached to the front page of the exam explaining the possible error in the grading. Do not make any changes or marks on the other pages of the examination. Portions of each examination are scanned or photocopied. You should be aware that any request for a regrade may result in a regrading of the entire exam. Therefore your total score may increase or decrease. Your responsibility: Check your grades on the WebAssign system every week or two and report any problems to both, the lecture instructor and the relevant TAs (and/or lab faculty) immediately. Lab and exam grades should be recorded for your review within one week from the date that papers are submitted for grading. Grading problems that are reported in a timely fashion will be investigated and, if action is warranted, corrected. 

Points for FlipItPhysics, clickers and Webassign HW

Clickers: 5 pts for right answer, 4 points wrong (or Qs with all answers equal), truncated at 80% of maximum available score. 
FlipItPhysics: Equal points for prelecture as for checkpoints, zero for HW, truncated at 20/22 in 122. 
WebAssign HW: Roughly 9 assignments with a total of at least 70 problems for the quarter, and NOTHING is forgiven or excused. 48 hour automatic extensions cost 30% of the work done after the original deadline. This penalty may be discarded for medical or other legitimate excuses on a case-by-case basis.

The Physics Study Center 

Students are encouraged to gather and work cooperatively in small groups in the Physics Study Center located in room AM018 of the PAB. (to reach the Physics Study Center, go down the stairs that circle behind the Foucault pendulum and proceed toward the end of the hall). Teaching assistants will be available for consultation during many portions of the day if your study group needs assistance, but staffing levels will not support much individual attention. The Study Center is staffed from approximately 9:30 AM to 4:30 PM on weekdays.
