Exam/Quiz Dates
There will be 6 quizzes, 4 exams, and a final exam. The quizzes will be 10 minutes each, given at the end of the scheduled class. Quizzes will tend to be 48 questions styled after the two minute questions and the end of the chapters. Rarely will you be asked to perform a detailed calculation on a quiz. Exams will be 50 minutes, but I will always allow you to stay the extra 10 minutes until noon. Exams will typically contain 23 challenging problems similar to the "S" problems at the end of the chapters. You may also be asked to explain your reasoning or the relevant concepts. The final exam will cover all of the material from the semester. It will consist entirely of conceptual or short calculation questions and will be primarily multiple choice. Exam 4 and the final exam will be given together during the final exam period. While both exam 4 and the final will be designed as one hour tests, you will have the entire three hours to work on them.
NOTE: The final exam schedule has not yet been posted by the registrar.

Homework
You should visit Useful Computer Programs and install the ProbViewer 1.4 program. This program will allow you to view problem solutions as they become available. You will also be able to see the answers to the two minute problems, which will be posted the class before each exam.
The password for the ProbViewer software will be emailed to you separately.
Daily Homework
At the beginning of each class, you will hand in solutions to two homework problems associated with the reading assignment for that day. You must be present for class to earn credit for these problems. These problems will be graded on a 5point scale using the following general guidelines:
 5: good effort with correct results and reasoning
 4: good effort with minor errors or a fair effort with no conceptual or math errors
 3: good effort with modest conceptual errors and/or math errors or a fair effort with minor errors
 2: fair effort involving modest conceptual errors or a good effort involving serious conceptual errors
 1: poor effort
 0: no initial effort
A good effort involves at least some English explanation and/or use of appropriate diagrams along with calculations and/or some recognition of an implausible result. If you cannot solve a problem after a reasonable effort you should at least indicate in words what information appears to be missing, and/or where and why you are stumped. Be sure to write something for every part of a problem. You will earn a maximum of 2 points if you do the wrong problem.
Graded problems will be returned by the next class session and solutions will be posted to be visible in the ProbViewer program. You must download and install the Probviewer program immediately (scroll down to "For All Units"). You may use the solutions and a colored pen/pencil to correct any problem that you wish (even if you did not submit an initial effort). Be sure to correct effort deficiencies as well as math errors. Submit corrected work to the box on my office door or bring them to class no later than one week after the problem was initially due. Your correction will be evaluated on a 2point scale:
 2: everything is suitably corrected
 1: some items uncorrected
 0: major issues uncorrected
The correction points will be added to your initial score (up to a maximum of 5) to yield your final problem score.
Since part of the goal of the homework is to make sure that you are prepared for class, late homework (either corrections or initial efforts) cannot be accepted. However, I will drop the lowest 3 homework grades. AND, if at least 90% of the class completes the SPTQ at the end of the semester, I will drop the next 4 lowest homework grades (a total of the 7 lowest homework grades). This will give you the flexibility to deal with alarmclock failures, minor illnesses, field trips, family emergencies, big papers, unexpected romances, etc.
Weekly Homework
In addition to the daily problems, two or three weekly problems will be due each Wednesday at the beginning of class. These problems will help you to review the previous week's material, and typically will be more challenging than the daily problems. You do not need to be present for class to earn credit for these problems.
I expect the daily problem solutions to be somewhat sketchy, but on the weekly problems I would like you to make an effort to write a solution that is coherent and clear as well as correct. I will therefore grade these problems on an 8point scale, with the extra three points devoted to quality of presentation issues such as the following: Does the solution provide adequate diagrams and/or explanations of the model? Does the solution use units and vector notation correctly? Does the solution avoid doing algebra with numbers? The grading rubric for these points looks like this:
 3: great presentation
 2: minor presentation problems
 1: major presentation problems
 0: extremely poor presentation
Use the posted solutions as examples of excellent style ( though in many cases, you can write an excellent solution with far fewer words).
Just as with the daily homework, you may correct weekly homework problems: simply submit them within a week of the date they were originally due. You can earn up to 3 points back on an 8point problem (the 1 extra point is for correcting presentation issues).
Reading Assignments
It is essential that you complete the reading assignments before every class. The homework that is due that day is based on the reading for that day. Since class time is limited and Physics is an expansive subject, we will not cover everything in the text in class. However, you are responsible for everything in the text. All class activities will assume that you have read the text.
Exams and Quizzes
There will be 6 quizzes, 3 exams, and 1 final exam.
 Quizzes will be closedbook and closednote. They will be administered at the end of selected classes and will consist of conceptual problems similar to the 2minute problems in the text.
 Exams will consist of 2 or 3 short essay problems and will also be closedbook and closednotes. They will consume an entire 50minute class period, though I will always allow you to stay for an additional 8 minutes.
 The final exam will be comprehensive but will consist primarily of conceptual questions.
Labs
Lab will meet (nearly) every week in Pfahler 108. Please review the lab manual appendices:
Lab Turnin/Grading
For most of the labs, there is nothing to turn in. When your group feels that it is finished with the lab, you may request to "check out" with either the lab instructor (me) or the lab assistant. The check out procedure is as follows:
 Show and explain final data and graphs. Note: This should happen throughout the lab period as well.
 Answer questions posed by instructor/assistant.
 Some questions will be group questions to be answered by all.
 Other questions will be directed to individuals.
 All questions must be answered satisfactorily to check out. If that is the case, your group earns a 10/10 on the lab and may leave.
 If the questions are not answered satisfactorily, your group must return to your table and figure it out. You may then attempt to check out again.
Grading
You will be graded based on 5 components:
 Exams: 36%
 Quizzes: 9%
 Final Exam: 10%
 Homework: 30%
 Lab: 15%
You can determine your grade on any assignment (or overall) by dividing the points you earned by the points you could have earned, multiplying the result by 20, rounding to the nearest integer, and consulting the following chart:
20  19  18  17  16  15  14  13  12  11  10  9  8 
A+  A  A  B+  B  B  C+  C  C  D+  D  D  F 
Grading is on a fixed scale, so you will never be competing with each other. If class performance on any particular item is particularly low (indicating that the item was unusually difficult) I may adjust grades to be higher that this scale would indicate, but I will never adjust your grade to be lower.
