Tipler and Gene Mosca (W. H. Freeman and company). I-CLICKER Audience response device, ISBN 0-7167-7939-0 Publishers Bedford, Freeman and Worth To active your I-Clicker you will need to place the ID-code from the device into CHIPS the first time you login. You should do this as soon as possible as the I-Clicker will be used during the first week of the class, both in lecture and recitation. COURSE EFFORT Electromagnetism is a beautiful and exciting topic to study. Physics 241 is a 3 credit hour course. You are among an elite group of the best students in the world and have the strong will and intellectual capability to delve deeply into this practical yet aesthetically pleasing topic. You will be working every day for 16 weeks to complete this course. Remember that for every hour in class you can expect to spend an additional 2 hours outside of class in perpetration, contemplation, reflection, debate and study. Therefore in order to take full advantage of this rare opportunity to pursue such an intellectually challenging and rewarding topic you can expect to spend approximately 9 or more hours outside of class each week. This class forms the core intellectual base of engineering and physics. Your hard work and commitment will pay great
dividends as you gain a strong understanding of how the physical world around you works in a fundamental and powerful way. It is important that you place the correct amount of work time into your schedule at the beginning of the semester for this course. Do not fall behind. There are not enough hours in the week to catch up with the course, especially considering the other classes that you are taking. PREREQUISITES PHYS 152/172 and MA 162 are prerequisites for this course. You are expected to have a good understanding of classical mechanics, be able to differentiate and integrate simple functions, and be familiar with vectors, including dot and cross products. COURSE STRUCTURE The course has 4 main components: lecture, homework, recitation and exams. The lectures will introduce the material and concepts, and illustrate these ideas through presentation and demonstrations so that the student develops an understanding of fundamental concepts. Because the fundamental method of discussing and communicating physics ideas is through the language of mathematics, the homework develops the students skill at producing logical mathematical arguments using the physical theories presented in the course. Recitation is the place for the student to interact with an experienced physicist in order to develop better problem-solving skills. In addition the student will through interactions in class see that the mathematical arguments the student is developing are completed and the student will learn to communicate physical concepts correctly. Finally the exams cause the student to completely review the material presented and tests the students ability to communicate physics ideas through the language of mathematics. COURSE WEBPAGE You can find this syllabus, course announcements, learning center hours and other important resources on the PHYS 241 webpage: http://www.physics.purdue.edu/phys241/. The Physics Department webpage: http://www.physics.purdue.edu. We will use the Computerized Homework In Physics (CHIP) system to assign credit for homework completed during the semester. Instructions for CHIP will be provided on a separate handout. The CHIP webpage is: http://chip.physics.purdue.edu/public/241/fall2009/. ASSIGNMENTS The reading and homework assignment schedule is at the end of this syllabus. You should read the assigned sections before coming to each lecture. Students who read the assigned material before class will find the lecture far more meaningful and will do much better during the in class interaction questions. At the start of each lecture you will be asked a question concerning the reading material. The lecture response system using interactive devices will be used to record your response.
LECTURES The lecture will be used to introduce new material and concepts. You will be asked questions during the lecture and your response will be recorded. Typically you will be given about 1 minute to respond. During the response period you are expected to discuss the possible response with other students around you. This discussion is important to the learning process as it helps you to articulate the material that is being introduced. This is a dynamic process and you should not simply take an answer from another student but listen to their arguments and develop your own argument during the answer period. The sum of all your responses will be included into your final grade. There will be no I-clicker questions make-up if class is missed. Your final I- click grade will be adjusted for excused absences. Because the number of questions asked in lecture will vary with the lecture and the class response, you need to attend the lecture you are assigned to. Lecture scores will not transfer across lecture sections. Lecture is also your chance to ask questions and to discuss things that you find interesting or hard to understand. Please ask questions, as they are an important part of the learning process. Demonstrations and discussions will take place during lectures to illustrate the physics concepts. EXAMS There will be two evening exams and a final exam. The evening exams are multiple-choice and written to be completed in an hour. You will be allowed 2 hours to complete the exams. The times and locations of the evening exams are as follows: Exam 1: Wednesday, September 30 from 8 p.m. until 10 p.m., ELLT 116 Exam 2: Tuesday, November 10 from 8 p.m. until 10 p.m., ELLT 116 Your room assignment for the exam will be post in class during the week before the exam. All exams are closed book. For the exams you will need a #2 pencil, a calculator and your student ID. The equation sheet for each exam will be posted on the course website one week before the exam. Suggested additions to the equation sheet should be made to your lecturer. Many, but not all, formulae will be on the equation sheet. Cheating will result in a course grade of F and a reported to the Dean of Students. RECITATIONS Students are expected to do homework problems and study for the Recitation quiz each meeting. Recitation quizzes will require the use of the I-Clicker. You will need to have your I-Clicker operational for each class.
During Recitation, you will have the opportunity to discuss in detail the homework problems that have been assigned. You are expected to attempt all the assigned problems BEFORE attending Recitation, as the deadline for the homework is 11:59 PM on Wednesdays & Fridays (see CHIP Homework below). If you are familiar with the problems then you will benefit more from the discussions in Recitation. Delays due to special events or sickness must be discussed with your TA. Quizzes will be given in Recitation every meeting. There are no make-ups for missed Recitation quizzes; however your three lowest Recitation quiz scores will be dropped. Your total Recitation quiz score will be normalized at the end of the semester to eliminate discrepancies due to differences in the difficulty level and grading of the quizzes given by the various TAs. CHIP HOMEWORK There will be 26 Homework assignments. Each homework problem has randomly generated input values so each student will have a unique answer. Make sure that you use your own input values when solving each problem. To receive credit your answer must be within ± 1% of the correct answer, so you are advised to CARRY AT LEAST 4 SIGNIFICANT FIGURES IN YOUR CALCULATIONS. The CHIP grading policy can be found by clicking on the Grading Policy Details button in any CHIP assignment. A Multiple-choice problems have a limited number of attempts depending on the number of possible answers. If you answer correctly within the specified number of attempts and before the specified deadline, you will get 100% credit. Within one week after the deadline, but still within the allowed number of attempts, you obtain 50% credit. No credit is granted after one week past the deadline or if you used up the maximum number of attempts. B Numerical problems have a maximum of 5 attempts before the deadline to obtain 100% credit. Within one week after the deadline and within 5 first attempts, you will receive 50% credit. No credit is granted after one week past the deadline or after using all 5 attempts. GRADING POLICY: There are two evening exams and a final exam. The components of the letter grade and their maximum values are: Two Evening Exams 200 Final Exam 150 CHIP Homework Assignments 150 Recitation quizzes 100 Lecture quizzes 100 TOTAL 700 Letter grades will be derived using a curve, which has not yet been determined. ABSENCES AND EXCUSED GRADES: There is no way to make up missed evening exams or quizzes. Excused grades will be given only in one of the following circumstances: (1) illness; (2) personal crisis; for example, automobile accidents, required court appearance, incarceration, death of a close
relative, and (3) required attendance at an official Purdue activity. You must contact Professor Koltick by e-mail as soon as possible but BEFORE the exam or quiz. Appropriate documents (e.g., a written note from a doctor, with his/her name and phone number included) may be needed to judge the merit of the excuse. MISSING THE FINAL EXAM CANNOT BE EXCUSED. Exams Unexcused absences from any evening exam or quiz will be assigned a zero grade. At the end of the semester an excused absence for a single exam can be made up by taking a comprehensive exam, similar to a final exam or course test out exam. The grade on this comprehensive exam will replace the missing single excused absence. Exams will be considered open for 30 minutes from the official start of the exam. During this period no student is allowed to leave the exam. 30 minutes after the start of the exam students will be allowed to leave the exam and the exam will be considered closed. No student will be allowed to enter the exam once it is closed. Without exception any student not in the exam room at the close of the exam will be given a zero and will be recorded as having missed the exam. Lecture and Recitation quizzes A similar procedure will be applied to excused quizzes. Excused grades will be given only in one of the following circumstances: (1) illness; (2) personal crisis (e.g., automobile accidents, required court appearance, incarceration, death of a close relative and (3) required attendance at an official Purdue activity. You must contact Professor Koltick as soon as possible but BEFORE the exam or quiz. Appropriate documents (e.g., a written note from a doctor, with his/her name and phone number included) may be needed to judge the merit of the excuse. CHANGING SECTIONS You may change your RECITATION section only with the permission of the new Recitation instructor. You must then get a Recitation section change form from Physics Room 144 and have the new instructor sign it. You must then take the form to the Registrar's office, room 45. You must have a good reason to change recitation sections; recitation instructors are under no obligation to accept additional students. Make sure your grades are transferred to your new instructor. CHEATING Cheating will not be tolerated. If you are willing to put in the effort studying and practicing, you will have no problem earning a respectable grade. Working with other students on your homework is not considered cheating, and, in fact, is encouraged. However, direct copying of another's homework is considered cheating. A student who is caught cheating on an exam will receive an F for the course and be reported to the Dean of Students. In more serious cases the student will be suspended or expelled from the university. The same applies to all other parties involved in cheating.
HELP CENTER Help is available in room PHYS 11, which is the Physics 241 Help Center. Hours when the help room is staffed will be posted on the door soon after the semester starts. It will be open during finals week, but only on a limited basis. PHYSICS LIBRARY The Physics Library is located in room PHYS 290.
