Grading

The average final grade in this course has historically been a B-. Your grade in this course reflects only on your performance over a short period on limited subject matter. Your grade does not reflect on you as a person, nor on your full range of abilities in communication, writing, enthusiasm, logic, creativity, perserverance, entrepreneurial spririt, and a host of other talents which are crucial for achieving your career and life goals. In short, do not cause yourself (or your instructors) anxiety by making more of your grade than it really is.

Exams

Homeworks will contain mostly quantitative problems, whereas lectures will provide you with largely conceptual, multiple-choice questions to tackle in class. Hence, the exams will contain both quantitative and conceptual problems, and have both multiple-choice and written formats. The exams will be closed book and closed notes. You may use a calculator. No make-up exams will be given without prior arangement. If you have a conflict with an exam time, inform the instructor well in advance.

Partial credit: One negative aspect of the multiple-choice format is its ``all-or-nothing'' nature. For this course's exams, you may alternatively earn partial credit on a multiple-choice problem by opting to select two of the possible answers. For example, if you answer both A and C on a 4 point question that has the possible choices of A,B,C,D, you will earn 2 points if either answer A or C is the correct solution.

All examinations are required and none of the scores will be dropped or replaced. The exams will be held at the following times, and will tentatively cover the following chapters in Young & Freedman:

Exam 1	Thursday, March 3, 5-7pm	Ch 1-5
Exam 2	Thursday, April 7, 5-7pm	Ch 6-10
Exam 3	(Finals Week) Friday, May 13, 10:15am-12:15pm	Ch 12-16

Homework

The assignments will be posted on-line via the MasteringPhysics website below. Students are encouraged to work together, but each student must submit their own work. Homeworks will consist of approximately 10 problems each week. About eight will be answered and graded online, and two will be turned in on paper to be graded. The deadline for each homework will usually be Fridays: the on-line questions would need to answered by 10:00 pm and written problems are due at the start of lecture.

For the written exercises: As in ``real life,'' you should give credit to any sources or people you find helpful. For example, if you work on a problem in a group, the names of all the other members in that group should be given. To receive full credit, your homework must be legible and the logic must be easy to follow. No credit will be given for incomplete work or incorrect units and late homework will not be accepted. Neither faxed nor e-mailed homework will be accepted. Please staple loose sheets together.

Homeworks #0 and #13 will not count toward your final grade. Of the remaining 12, the lowest two scores will be dropped, so that your homework grade will be based on the best 10 scores.

The best way to learn physics is practice, practice, practice. Completing the homework problems is the best way to get this practice. Solutions to assignments may be available online or from your friends, but if you do not do the work yourself, you are only cheating yourself.

MasteringPhysics.com advice and information:

• If you buy a new book, a MasteringPhysics access code kit will come bundled with your book. If you buy a used book, you'll have to purchase MasteringPhysics access seperately, either online at MasteringPhysics.com or at the bookstore desk.
• The procedures for self-registration are explained at www.masteringphysics.com (this is also the login site). Your access code is inside the student access kit that comes with the text (please see me if you do not have the kit). The course ID is ``JANGCONDELL2016''. You may choose your login and password. Be sure to select the option for MP which accompanies the Young & Freedman 13th Edition textbook.
• Never use the browser's ``back'' button. Use the links provided.
• You will be able to submit answers as many times as you wish. Incorrect answers will be given partial credit as follows: for multiple choice answers, you will lose 100%/(number of options-1) per incorrect answer. This means that no credit will be award for an incorrect true/false response. For all other questions, 3% will be deducted per incorrect response. Please hit "submit" after answering each question. Selecting "submit problem" will result in the problem being graded.
• Some problems have multiple components, so be sure to answer each portion.
• Many problems have hints to help you along the way. You will not be penalized for looking at the hints, and sometimes bonus credit will be awarded if you answer correctly without peeking at the hints. Either way, you win. Note that this possible bonus credit will be an extremely tiny fraction of your overall course grade, so please don't agonize over the choice.
• Parameters may be randomized! Your friend's question may have different numbers.
• There is a 2% tolerance for answers; e.g. you can be off by, say, 1.8% and receive full credit.
• Solutions to the homeworks will be posted at the course website.

Entering Formulae in Mastering Physics:

Sometimes Mastering Physics will ask you to enter algebraic formulae as your answers. Here is a chart on how to convert common formula into Mastering Physics symbolic language. Also, be sure to do homework #0 where you also get to practice this.

Formula	Mastering Physics Coding
$\frac{1}{2} a_x t^2$	1/2 a_x t^2      -or-     1/2 * a_x * t^2
$\mu_s/(F_1+F_2)^2$	mu_s/(F_1+F_2)^2
$\sqrt{a^2+b^2}$	sqrt(a^2 + b^2)
$v_0^2+a\Delta t$	v_0^2 + a Delta t
$3\times10^8$	3 * 10^8

Labs

Labs will consist of 3 parts: a pre-lab assignment, lab activities, and a post-lab assignment. The pre-lab assignment is to be completed before you come to lab and must be turned in at the beginning of the lab period. The post-lab assignment must be turned in by the next lab meeting. Points will automatically be deducted from late work. Thus, it is better to do work late rather than not at all, but it will be difficult to do well in this course if you are consistently late.

If you must miss a lab, you may attend another lab the same week to make it up. Makeup labs outside of the regularly scheduled times will not be done. Your lowest lab grade will be dropped in calculating the lab component of your final grade.

Polleverywhere

In each lecture, at least one question will be posed to the class using polleverywhere. You will earn 1 point for each question you respond to, and a 1 point bonus for each question answered correctly. Your polleverywhere grade will be out of 100 points. After 100 points, additional responses will be treated as extra credit, counting for half points. These points will be graded beginning the second week of class.
