FAQs
What is Physics 220?
Physics 220 is electricity and magnetism.

It's been a long time since I took calculus. Do I need to be concerned?
Compared to Physics 121 and Physics 123, we do use a lot of calculus. However, I don't expect you to remember all of the details from your math classes. You do need to understand what derivatives and integrals are and to be able to do integrals and derivatives of simple functions. You should be thoroughly familiar with the product rule and the chain rule for differentiation. You should also be familiar with techniques of integrating over surfaces and volumes.

I've heard this course is hard. How much time will I need to spend for this class?
You should plan to spend at least six hours per week outside of class. Some students find they need to spend considerably more time. Some can get by with less.

How easy is it to get a good grade?
That's a hard question because some "good students" find physics difficult and some "not-so-good students" find it fairly easy. My best answer is that about 1/3 of the class get an A− grade or better. The department requires me to have an avarage GPA no greater than about 3.2. There are more details on grading below. Students who are willing to work hard seldom receive grades lower than C.

Can I attend the other section of Physics 220?
Yes. We will cover essentially the same things in Section 1 (10:00 am) and Section 2 (11:00 am). I will count your clicker score from either section.

Official Learning Outcomes

The learning outcomes established by the department for Physics 220 are:
• Solve problems and answer conceptual questions involving electromagnetic energy (potential), forces, and the motion of charged particles and dipoles.
• Use Maxwell's equations to find electric and magnetic fields in symmetric arrangements of static charges and steady currents. Also find electric and magnetic fields by integrating over charge and current densities.
• Analyze simple direct current and alternating current circuits of resistors, inductors, capacitors and power supplies.
• Use Maxwell's equations to solve problems and answer conceptual questions with changing electric and magnetic fields, including induction and electromagnetic radiation.

Getting Started

Course Website
Most everything you need for the course can be found on the course website.

Learning Suite
One important thing I have put on Learning Suite is the class schedule. It lists assigned reading, due dates, etc.

Text and clickers
The text for this course is Principles of Electricity and Magnetism, which is available online. You will find that the text is the most important learning tool in the course. On the Class Schedule is a list of the sections which we will be covering each day. Please read the sections from Principles of Electricity and Magnetism before the listed class period.
You also need to buy a standard BYU classroom transmitter (iClicker) or you may alternatively use any device that connects you to the internet so you can take quizzes in class through Piazza.com online.

CID Numbers
If you were on the rolls a couple of weeks before class started, you should receive an email with your class identification (CID) number. You should register your CID and your clicker number on the course website. Your clicker is NOT automatically registered in this class if you registered it with the university. You will find a photograph showing the location of the iClicker identification number on the registration web page. You may change your password when you register  your clicker. Passwords are case sensitive.
If you do not receive a CID number by the first day of class, please send me an email at Lawrence_Rees@byu.edu.

Coursework

Lectures and Classroom Exercises
The lectures are an important part of class. Although I provide a copy of Power Point slides, this is not an independent study course.
Each day we will have at least one Classroom Exercise, a short question or problem to work in class. You will use your clicker to answer the question. Each question will be worth three points. You will receive two points for completing the question and one point for a correct answer. If your total score is 75% or better, you will receive full credit, so most students receive full or nearly full credit for Classroom Exercises.
If your clicker batteries are dead, please check with me before class as I often will have some spares I can loan you. If you forget your transmitter you will lose the points for that day. Making adjustments for these occurrences require a considerable amount of work and are not significant enough to change your final grade. If you are ill, have an excused absence, or lose your transmitter, send me an email and I will give you credit for the missed quizzes. Note that you are responsible to replace lost transmitters as soon as possible, however.

Walk-in Labs
Several short laboratory experiments will be set up in S-415 ESC. Please carefully check the Class Schedule to find the dates when which each lab will be available. Labs are changed each week on Monday mornings. I would recommend that you do the labs early in the week as the labs are less crowded and you have some flexibility to come back in case there are problems beyond your or our control. You will submit your labs online. A hard copy of the online lab will be available in S-415, so you won't need to print a copy to take to the lab with you. Completed forms are due on the Monday after you have done the lab. You will receive full credit for the labs if your score is 80% of the total possible score.
If you miss a lab because of extended illness or for university excused absences, please let me know and I will give you credit for it.

Homework
Homework, Mastery Checks, Quizzes, and Basic Tests are administered on online. The online program grades each problem as soon as you submit it, gives some hints and helps, and provides you with a range of correct answers. Note the following:
• Homework is due at 11:55 p.m. every Thursday.
• Each assignment covers one lesson in the text, but note that some assignments are longer than others, so you may need to get started on some assignments early.
• You have three tries to get each problem correct. Except for multiple choice questions, you receive full credit if the answer is correct on any of the three tries. You are also allowed three tries on multiple choice questions, but they are worth less after each try.
• If you score 85% or better on homework, you receive full credit for homework.
• Homework problems submitted late are penalized 20% per day late; however, the maximum late penalty is 90%

Mastery Checks
The course is divided into 13 lessons. At the end of each lesson, you will take a Mastery Check and a Quiz online. The purpose of the Mastery Check is to help you assess how well you learned the lesson material. These consist of a combination of multiple choice questions and problems. The Mastery Checks have a few hints and possibly some feedback that may be of help. Please carefully note the following rules for the mastery checks:
• You may use any written materials (notes, books, web pages, etc.) while you are taking the mastery check.
• As with homework problems, you are allowed three attempts on each question. There is no penalty for wrong answers except on multiple choice problems.
• Mastery Checks and Quizzes are both due on Saturday at 11:55 p.m.
• I expect you to turn in Mastery Checks on time. There is a 12.5% penalty per hour late.
• If there are extenuating circumstances that prevent you from submitting a Mastery Check on time, complete it as soon as possible, then afterward send me an email explaining your circumstances.
• I would like these checks to provide everyone with a valid assessment of their understanding, but this cannot be done if students who have not finished the Checks hear discussions about the problems in the Tutorial Labs. Therefore, please do not ask TAs questions about the Mastery Checks until after the due date has passed.

Quizzes
At the end of each lesson, you will also take a Quiz. Whereas Homework and Mastery Checks are primarily learning exercises, Quizzes are to provide me information about how well you have learned the material. They can also help you identify areas of weakness before you take the midterm exams. These Quizzes will be very similar to the Mastery Checks, except that they are closed book, and they will have neither hints nor feedback.

Please carefully note the following rules for Quizzes:
• You may not look at any written materials (notes, books, web pages, etc.) while you are taking the quiz.
• You may not discuss these Quizzes with anyone before or after the test, with the exception of Dr. Rees.
• You may not use equations stored in your calculator. (You may use stored constants, however.)
• You must take the test in "one sitting." What I mean by that is that you must take the Quiz essentially as if you were in a classroom and I were monitoring an exam. I would let you get a drink or go to the restroom, but I wouldn't let you chat with your friends in the hallway or take half the test in the morning and half in the afternoon.
• Due dates, rules for multiple attempts on problems, and the late policy are the same for Quizzes and Mastery Checks.

Basic Tests

Each exam (midterms and final) will have one section of basic questions that I expect you to asnwer correctly.
• The questions will be conceptual questions or simple, one-concept applications of the most important ideas.
• A set of all basic questions for each test will be available online so you can study them in advance.
• I will give you ten of these problems (with different input values) on the Basic Test.
• The Basic Test will be available online. You may NOT use any books, notes, written materials, or online materials of any kind. You may not use equations stored in your calculator.
• There will be a time limit imposed.
• You may retake the test without penalty as many times as you wish.
• If you miss no more than one problem, you will automatically recieve 30 points on your regular exam in the Testing Center and will skip the basic question section of that exam. (The midterm exams are worth 100 points and the final exam is worth 150 points.)
• If you do not pass the Basic Test with 9 or 10 problems correct before taking the Midterm Exam, you will need to complete the basic section of the exam in the Testing Center. This section will be worth a maximum of 30 points.

Midterm Exams

There will be two midterm exams given during the semester. Please note the following:
• These exams will be administered in the Testing Center.
• The exams will include multiple choice questions much as the quizzes and mastery checks.
• The exams are machine scored by the Testing Center with answers entered on bubble sheets.
• No books (except foreign language dictionaries) will be allowed. Calculators are permitted, but you are not permitted to use information stored on your calculator.
• There are no time limits.
• All exams in the Testing Center end at 4:00 p.m.! Please note this carefully! This means that tests will not be given to you after 4:00 p.m. without special permission.
• You may not take a test late unless you have a valid reason for doing so. Please contact me as soon as possible if you need to take a test late.
• Because of my alternative methods of grading, I need to have about the same distribution of scores for each test. To do this, I will adjust the exam scores (the final, too) so that 80 points will be the average and 100 points will be two standard deviations above the average.

Final Exam
The final exam will consist of two parts: The first part will cover the last section of the course and will be very similar to the midterm exams. The last part will be comprehensive and will consist of multiple choice problems based on the Basic Tests. There is no time limit; most students will finish within two hours. The final exam will be given through the Testing Center and will be available throughout the final exam period.

Helps

Tutorial Lab
The Physics Tutorial Lab is available in N-304  ESC. All TAs in the lab should be able to help with Physics 220 question; however, some of the TAs are specially prepared to work with Physics 220 questions. These TAs are identified with Physics 220 badges.

Weighting
The various components of the course will be weighted as follows:  Item Full Credit at Weight Classroom Exercises 75% 5% Walk-in Labs 80% 5% Homework 85% 10% Mastery Checks 5% Quizzes 15% Midterm Tests 40% Final Exam 20%

The "Full Credit at" column indicates the percentage required to receive full points for that item. Thus, if a student gets 87% of her homework correct, she receives full credit for homework. If she gets 42.5% of her homework correct, she receives half of the total possible points.

At the end of the semester, your grades will be adjusted to help compensate for anomalously low test scores and low incentive grades. In determining letter grades from adjusted scores, note that only percentile breakpoints apply, not the percentage breakpoints. Your scores will be adjusted in three steps:

1) Straight percentages. Your class rank will be determined by the straight, unadjusted method described above.

2) Adjusting test weights. I will lower the weight on you lowest exam (midterm or final) by 10% and increase the weight on the other two exams by 5% each. For example: the basic weights for the midterm and final exams are 20% each. (That is, the first midterm counts for 20% of your final grade, etc.) If your score is lower on the first exam than the other two, your weight on the first midterm will be 10%, your weight on the second midterm will be 25%, and your weight on the final exam will also be 25%. Your class ranking will then be calculated using these modified scores. Because of this, if you do poorly on one exam, it will affect your final grade less.

3) Your class ranking will be calculated based on a) adjusted tests only, b) adjusted tests, quizzes and mastery checks only, c) adjusted tests, quizzes, mastery checks, and homework only, d) adjusted tests with all other components. Your final class rank will then be the highest of the five ranks calculated above.

Letter grades are based on your class ranking. Below is a list of the letter grades that correspond to your percentile ranking among students passing the course. Since the class is quite large, the distribution of scores is fairly predictable; however, I may adjust the breakpoints in your favor if I feel that it is warranted.

 Percentiles Letter Grade 85 – 100 A 67 – 85 A– 50 – 67 B+ 36 – 50 B 22 – 36 B– 14 – 22 C+ 10 – 14 C

I will individually review and assign all grades of C− or lower.

Legal Notices

The College of Physical and Mathematical Sciences suggests that the following statements be included in all course outlines. Please note that I fully endorse these policies.

Harassment
Harassment of any kind is inappropriate at BYU. Specifically, BYU's policy against sexual harassment extends not only to employees of the university but to students as well. If you encounter sexual harassment, gender-based discrimination, or other inappropriate behavior, please talk to your professor, contact the Equal Employment Office at 422-5895 or 367-5689, or contact the Honor Code Office at 422-2847.

Disabilities
BYU is committed to providing reasonable accommodation to qualified persons with disabilities. If you have any disability that may adversely affect your success in this course, please contact the University Accessibility Center at 422-2767. Services deemed appropriate will be coordinated with the student and instructor by that office.

Children in the Classroom
The serious study of the physical and mathematical sciences requires uninterrupted concentration and focus in the classroom. Having small children in class is often a distraction that degrades the educational experience for the entire class. Please make other arrangements for child care rather than bringing children to class with you. If there are extenuating circumstances, please talk with your instructor in advance.
