This term focuses on electromagnetism and light. Specific topics include: the Electric Field, Electric Potential, circuits, Magnetic forces and Fields, Electromagnetic Induction, Electromagnetic Waves, Wave Optics and Ray Optics. Math Prerequisites: MTH111 (College Algebra), and MTH112 (Trigonometry) – preferred You’ll have a brief math refresher assignment the first week of class to make sure you can solve basic algebraic problems like two equations and two unknowns, the quadratic formula, etc., but beyond that it is expected that you can use math to solve problems. Lecture: MWF 9:00 – 9:50 am in NS 101 Lab & Recitation: Lab section 1: Thursday 10 - 12, Lab section 2: Thursday 1-3 in NS 217 Class Materials: PDF’s of all course materials can be found at www.wou.edu/~schoenfw/PH203 Course Materials Textbook: College Physics, by Knight, Jones & Field, Prentice Hall Online Homework System: Mastering Physics There are two options you'll have for textbooks this year for physics 201/202/203. The class will require the purchase of two things: a textbook (technically this is optional, but highly recommended), and access to the online homework system called Mastering Physics. Available at the bookstore is a bundled package from the publisher that contains the brand new second edition of the textbook, along with an access code for Mastering Physics. It will cost around $240, but will be used for all three terms. Since the second edition is brand new, you will be able to sell your textbook at the end of the year if you so desire. The second option (cheaper initially) would be to buy the older 1st edition of the textbook. The bookstore cannot get old editions from the publisher, and is unlikely to hold onto copies that have limited worth. The first edition is virtually identical to the second edition, and is a perfectly acceptable substitute. You'll save some money, but will have to get them own your own. (Used copies should be available on campus.) Note however, if you buy the first edition you most likely be unable to sell it at the end of the year. In addition you will need to purchase Mastering Physics directly at the publisher’s website www.prenhall.com, it will cost around $60 for the year. The information for the first edition of the textbook is: College Physics: A Strategic Approach, 1st Edition Knight, Jones, & Field, Prentiss Hall, ISBN-10 080530634X The second edition is: College Physics: A Strategic Approach, 2nd Edition Knight, Jones, & Field, Prentiss Hall, ISBN-10 0321595491 There will be at least two copies of the textbook available for your use in the physics lab; make sure they stay there for everyone’s use. Calculator: You will need a calculator for lecture, lab and exams. Any scientific calculator with trig, log, and exponential functions should be adequate; you do not need a graphing calculator. Devices with Internet access may not be used for exams. Grading Information Exam I Exam II Final Exam Online Homework Lab Score Total points available 100 points 100 points 200 points 250 points 100 points 750 points Exams Exams will consist of material covered in the textbook. The material will be mostly discussed in either lecture or lab, but given the pace of the course, some material will not get full coverage in either. It is the students’ responsibility to ensure that they have comprehended all the assigned material. Exams will have both conceptual and computational components. Exams will be closed book exams, but students will be allowed to bring one page of notes. Each exam (throughout the academic year) will focus mostly on the material covered since the last exam, but will be somewhat comprehensive in the fact that material covered on previous exams will be needed for subsequent chapters. Computational questions will require multiple steps to be performed for the student to earn both full credit, and partial credit, in the event of incorrect answers. A complete orderly solution should include: diagrams & figures, identifying the known’s and the unknowns, stating any assumptions you make, identifying valid equations and conserved quantities, displaying all significant mathematical steps, underlined final answer with appropriate units. Online Homework – Mastering Physics Weekly homework will be assigned on the website www.masteringphysics.com, and will give you the practice you need to learn physics. If you purchase the text new (2nd edition) it will come with a valid student access code to the website. Otherwise you have to purchase an access code directly from the publisher (www.masteringphysics.com). Your access will remain valid for one year. Mastering Physics is both homework and grading system, as well as an online interactive tutor. It has the ability to give hints (when requested) and provide specific wrong answer feedback to help you arrive at the correct answer. As the instructor, I have the ability to set the number of hints, and the number of attempts you will be afforded for each problem. The online homework is meant to help you develop problem-solving skills in physics. The course ID is: MPSCHOENFELD23874, you should enroll in this online course as soon as possible as there are two tutorial assignments already posted. Lab Each week we will meet for a 2-hour combined lab & recitation session. Our work will include: physics review sheets, solving group problems, investigating various physical phenomena by experimentation, and having interactive demonstrations. Sometimes there will be pre-lab activities due upon arrival; sometimes there will be post session activities to be turned in the following week. The physics lab is our opportunity to explore concepts in depth and to develop a sound foundation for physical reasoning. In an attempt to mix things up, I will routinely partner break up established groups, so that you have the chance to work with as diverse group of classmates as possible. Since the lab sections are full, please report only to the section in which you are registered. During the course of the year we will work with a multitude of electronic sensors, which will allow us to make measurements and interpret data in a fraction of the time it might have taken in years past. It is imperative that everyone learns how to use the computer interface and accompanying software. The end of term lab final will assess whether or not you became proficient in using this important laboratory tool. Each student is expected to keep a 3 ring binder in which they will keep all their lab work. Periodically throughout the term, and during the last week of classes, I will collect the binders to make sure you have completed your work. I won’t have the time to thoroughly grade every section of every activity, so you should check my solutions. Lecture Format Physics education research suggests that the standard mode of professors lecturing and students acting as scribes recording the information presented is perhaps the least effective way to learn physics. Whether you’ve studied physics before or not, you enter the classroom with a lifetime’s worth of ideas about the laws that the universe obeys. Research has shown that most of you come here with long held misconceptions that need to be changed in order for you to fully succeed in this course. (Don’t feel embarrassed, Newtonian Mechanics as it is known, is very counter intuitive, it wasn’t understood until Newton in the 17th Century, and his work was based on the work of Galileo & Descartes.) So, rather than me telling you the rules, I’ll ask you to predict what will happen if we perform a specific experiment, and observe the results. After the class has chimed in, we’ll see what nature does, and you’ll construct the rules for yourself. I’ll be the guide to shepherd along the journey. For this to be both successful, and fun, I’ll need two things from you. You come to class ready to challenge yourself (and others) by actively participating, and that you keep up with your reading in the textbook. Time Commitments Unlike most other university science classes, this is not a knowledge-based course (although there is some knowledge to be acquired). You will not have to memorize many facts. (In fact everything you learn in all three terms can easily fit on one sheet of paper.) Physics is a skilled-based course. The amazing thing about physics is that one can reduce most physical phenomena to a relatively small number of fundamental interactions. Our goal is show how objects that are orders of magnitude different in size, are in fact governed by the same basic laws. Thus we’ll be looking for similar patterns in how things behave. Accordingly, we’ll strive to fully understand just a limited number of concepts, but this will require a good bit of practice on your part. The general rule of thumb for a university science course is to spend 2 to 3 hours of time outside of class for every hour you spend in class. You will need to read the text, participate in lectures, prepare for lab sessions, do online homework, do practice study sheets, write up lab activities, and take exams. To do well, you should expect to spend at least 10 to 15 hours per week on this class. There simply is no shortcut in physics! Academic Honesty As your instructor I’ll strive to employ any method that helps increase student learning. The student – teacher relationship is based on honesty, fairness, respect, and trust. I hope that everyone will succeed by engaging in hard work. Violations of academic honesty will not be tolerated. Infractions in this class include: cheating on exams, inappropriate assistance, and turning work that you did not do yourself. Penalties for violations of academic honesty include, but are not limited to oral or written warning, a grade of zero for the assignment, a failing grade for the course. Much of the work you will do in this course will be done in groups. In fact, students are encouraged to find partners with whom to collaborate. I expect you to work together on lab worksheets, classroom clicker work, and online homework. However all partnerships are expected to be two way, all participants are expected to participate and contribute. Identical or extremely similar homework on turned in assignments is unacceptable. Discussing concepts and problems is encouraged, but you may not copy papers verbatim. Attendance Policy There is a direct correlation between attendance and student performance. Attendance in lecture is not required to pass the course, but experience has shown that in most cases it is necessary to do well in the course. The lecture component is designed to complement both the textbook readings and the lab activities. Attendance in lab is required in order to pass the course. Absences with written excuses for medical reasons or university-related functions may be used to arrange make-up the missed work. Feedback and Communication I generally check my email a few times per day and will almost always respond by the next day. I will grade work within one week of the due date. Religious Holidays Western Oregon University strives to respect all religious practices. If you have religious holidays that are in conflict with any of the requirements of this class, please contact the instructor as early as possible to make alternative arrangements. Students with Disabilities Students who have documented disabilities and would benefit from special accommodations during examinations should make an appointment with the instructor as early possible. Syllabus Amendment Policy This syllabus may be modified by the instructor as needed, to meet the learning objectives of the course. Students will be notified of any changes, and the reasons for the changes in a timely manner. Additional assessment activities may be added if the instructor deems it necessary in order to increase learning. “Dead” Week & Finals Weeks The 10th week of the term is regarded as a normal week of class. Expect to cover new material in lecture, and to have a normal lab session. This term our final exam is scheduled for the last day of finals week; expect to take that exam during its scheduled time. Do not make travel plans and expect to take the exam early. During finals week I will schedule multiple opportunities for students to take a short “lab final”. Missed Work Under NO circumstances will make-up exams be administered without prior arrangement (at least three days) and good reason, with a signed administrative or medical excuse. Lab exercises and demonstrations are set up on a weekly basis. Please show up during your assigned lab period. Switching weekly lab periods must be approved by the instructor, prior to attending lab. Incompletes A grade of incomplete (I) may be negotiated when a student with passing work needs additional time to complete the course. An incomplete will not be granted as a substitute for a failing grade (F), nor will a grade of "incomplete" be issued in the last week of class. If you find yourself in a situation where you can't complete the required course work, please make arrangements with the instructor prior to the last week of class.
