TBA TBA Desired Learning Outcomes This course is a University level, Calculus-based physics course designed to introduce you to scientific thinking and problem-solving on a level well beyond that covered in a High School science course. Where in High School science, the emphasis is often on introducing a formula and using it to produce a numerical result, in University Physics we are aiming at a deeper conceptual understanding of physical processes and systems. In this course you will need to analyze physical processes, static and dynamic, and correctly predict their outcomes. Students in science and engineering fields need to have an even deeper grasp of Physics and how it applies to the world around them. Mechanics and Thermodynamics, as covered in PHYS21, are directly applied by a Civil Engineer designing a bridge, a Biologist studying processes within a cell, as well as Geologist predicting the likely severity of an earthquake. You likely have heard that "Mathematics is the language of Science". You now have at your disposal a very powerful mathematical tool that was developed for the very purpose of describing physical processes. Calculus. This course will familiarize you with the practical application of Calculus concepts to the analysis of physical systems. At the end of this course, students will be able to: 1. Explain and analyze key concepts related to electricity and magnetism, circuits, optics, and waves. 2. Identify what physical principles are at play and what laws guide the outcomes. 3. Apply basic physical principals to solve practical problems. 4. Set up and carry on a solution to complex, multi-step problems based on the physical principals at play. 5. Apply Calculus concepts to physical systems to analyze change. 6. Develop habits of learning new scientific concepts independently, through reading and practice problems. Course Administration We will use Blackboard which you can access if you are registered for the course. The website contains news and announcements, the course syllabus, lab information, lecture notes, h o m e w o r k , and other useful information. Course Description This course is the 2nd part of the basic physics sequence intended for science and engineering majors and minors. Physics 1021 focuses on Classical Newtonian Mechanics, Fluids, and Thermal Physics; Physics 1 0 22 covers Waves, Electromagnetism, Circuits and Optics. You don't have to be a 'genius' to do well in the course, but you have to have the desire to learn new physics concepts and the commitment to carry out the assigned tasks. You need some basic math skills, including calculus and differential equations. Group Work Almost all of your in-class work will be conducted in groups of 3. There is heavy emphasis on the group dynamics in this course, and therefore it is very important that all groups function well as a team. If for any reason, you are experiencing difficulties in your group, you should bring this to the attention of the instructor. The smooth operation of the group work is central to our collaborative effort. Groups could be reconfigured during the semester as needed to facilitate better learning experiences. Your activity in the group will be evaluated and credit will be given in a manner that will be decided in class. Classroom Activities We will more or less follow the class schedule provided in the course calendar. The nature of the collaborative section is such that it is critically important that you come to class prepared to work on the material each day. Each week, you have to read the corresponding chapter from the textbook before you come to class. At the beginning at each class, we will have a 10 min reading quiz based on the material you‘ve read. We will spend our class time supplementing the ideas in the textbook and applying them to welldefined problems which will help deepen your understanding of the basic underlying physics concepts. Our in-class activities will include conceptual tests, written worksheets, and hands-on lab experiments. Mathematics Background Basic knowledge of simple differential and integral calculus, together with algebra, geometry, and trigonometry, is needed for this course. Therefore, a passing grade in Math 31 and 32 (or the equivalent) is required and a facility with these mathematical techniques is fully expected. If you do not meet these criteria, you will not be allowed to take the course. If you are in doubt about this requirement, please talk with the instructor on the first day of class. Warning: If your grade in Math 31 or 32 was lower than C, you have extra review work to do. See Appendix A of your textbook for a brief outline of such a mathematics review. You should do this review the first week of the semester. PHYS 22 Grading Policy In order to foster cooperation and collaboration among all of you, the course will be graded on an absolute scale (there will be no “curving” of grades). This means that helping your fellow students does not in any way jeopardize your own grade, and in fact, is likely to help you, since explaining things to others will help you understand things better yourself. Moreover, there will be various “group incentives” during the semester, and so it is also in your best interest to maximize the effort and performance of your group. 93.5 89.5 85.5 81.5 77.5 73.5 A AB+ B BC+ 69.5 65.5 61.5 57.5 55.0 below C CD+ D DF There are several components in the course, designed to maximize your learning and to assess that learning. Each component has its own weight in the overall grading scheme. Of the two schemes listed below, I will choose the one that optimizes your grade. Scheme 2 has a slightly higher weighting on the final to compensate for an anomalously low grade on exam 1 or 2. The breakdown of these components is given below: Scheme 1 Scheme 2 Midterm Exam 1 17.5% 15% Midterm Exam 2 17.5% 15% 20% 25% 5% 5% Lab Reports 10% 10% Weekly Quizzes 15% 15% Daily reading quizzes 10% 10% 5% 5% 100% 100% Final Exam Homework Assignments In class activities Total Note that the exams count for 55% of your total grade and the combination of in-class and at-home aspects of the course count for the other 45% of your total grade. This means that you have a great deal of control over your own grade. If you make the effort to earn the non-exam points, you will build a safety net for yourself in the event that you stumble in the exams. Please pay special attention to the homework assignments - if you are conscientious you should be able to score 100% on the homework which will have a significant impact on your grade. Exams There will be 3 exams for this course, two during the semester and one during the finals period. We will try to announce the exam times early in the semester so that you can plan for them in advance, however you should not make sure you are in campus until the last day of the Final Exams Period which is December 18 th . The exams are closed-book, but a formula sheet on standard paper (8.5 by 11 inches) is provided for each exam. The purpose in providing this information during the exams is to emphasize that formula memorization or plug-and-chug is not the main goal in this course. The focus is on understanding and problem-solving skills. Bonus points are built into each exam. If your grade on the first exam is lower than 70% you are required to attend the weekly office hours. Homework We will have weekly homework assignments, handled through the Mastering Physics online system which is tied to the textbook. This system will give you immediate feedback as to whether or not your answer is correct and hints if it is not correct. You will have up to 5 tries for most problems. Most of the homework problems are taken from the end-of-chapter problems. Feel free to discuss the problems with other students; however, you are responsible for submitting your own answers. Since the homework answers can be submitted at any time while the set is active, from any location where you have Internet access, no extensions on homework are granted. The homework is scored out of 140 points. This means that you can get 40 points of extra credit on each assignment that can make up for poor performance on other homework assignments. You can get a maximum of 100% on your homework grade for the course and everyone should be able to do this with the extra credit allowed. Lab Reports There will be labs integrated into the course. There is no lab manual to purchase. Instead, lab instructions are posted on Blackboard. You should read the instructions before going to the lab. Labs will be conducted as a group but each member must submit his/her own lab report. Each member must be physically present and must have participated in the experiment to receive credit. For this purpose, before you leave the lab, please get the initials of your lab instructor on your data sheet. Your instructor may also ask you to do some preliminary calculations to make sure the data make sense before you leave the lab. If necessary, you may be asked to repeat some measurements. No makeups for labs. Quizzes Reading Quizzes – As previously mentioned, at the beginning at each class there will be a reading quiz which will consist of 5 clicker questions. The reading quiz is a closed-books quiz. Students are allowed to bring an annotated formula sheet. Problem Solving Quizzes – At the end of each week, there will be a problem-solving quiz consisting of 1 to 2 problems. These quizzes are generally held on Fridays. The p r o b l e m s o l v i n g quiz will be closed books, but students are allowed to bring an annotated formula sheet. The lowest p r o b l e m - s o l v i n g quiz score will be dropped in the end. No makeups for quizzes. In-Class Activities These are short in class exercises, hands-on activities, or problems designed to help you understand specific physics concepts. Sometimes, a question will be posed related to the material covered, with multiple-choice answers. You will respond to such conceptual questions using your TurningPoint clickers. Sometimes I will ask you to engage in discussions with your peers before submitting your final answers. It is important that you participate actively in the ConcepTests and all the other activities, without hesitation for being right or wrong. Your classroom-related grade is a participation grade and you will not lose points for making a mistake. You may find that you will learn more from your mistakes. There are no makeups for the classroom activities. Peer Evaluations Each of your team members will evaluate your contribution to the team at mid-semester and at the end of the semester. Clearly, it is to your advantage to take your team responsibilities seriously. Gold Stars/ Extra Credit In this course you have several opportunities to obtain Gold Stars which are equivalent to 1 quiz extra credit point (10% of one quiz grade). You can earn Gold Stars by doing the following activities: prepare summaries of textbook chapters asking interesting questions in class present solutions in class with good problem-solving protocol and send the professor your whiteboard work find mistakes in the professor’s work present interesting applications of the concepts learned in your field of interest Other Matters Student’s Responsibility Your attitude toward the course should be one of self-responsibility. You will get out of the course exactly as much as you put in to it. Your responsibilities include: • Come to every class and participate actively in all of the collaborative work. • Consult Appendix A of the textbook to acquire the mathematical skills (algebra, vectors, and calculus) needed for the course. • Read the textbook carefully and gain a reasonable familiarity with the day’s material before you come to class. Come with questions in mind! • Work on the homework problems early and finish them on time. • Check the course website regularly for updates and course information. • Participate fully in all of the classroom activities (we said this already, but it is important enough to mention twice!). If you find that you are struggling with the coursework, seek assistance early so that you won't fall behind for even just one week. Help Resources • Society of Physics Students (SPS) Each semester the SPS offers free Physics tutoring to all students. Tutoring is held in the Gelman building and the hours change from semester to semester. I will announce the tutoring hours for this semester as they are made available. You can also contact sps@gwu.edu for more information. • Disability Support Services (DSS) Any student who may need an accommodation based on the potential impact of a disability should contact the Disability Support Services office at 202-994-8250 in the Marvin Center, Suite 242, to establish eligibility and to coordinate reasonable accommodations. For additional information please refer to http://gwired.gwu.edu/dss. • University Counseling Center (UCC) 202-994-5300 The UCC offers 24/7 assistance and referral to address students' personal, social, career, and study skills problems. Services for students include: crisis andemergency mental health consultations; confidential assessment, counseling services (individual and small group), and referrals. For additional information please refer to http://gwired.gwu.edu/counsel/CounselingServices/AcademicSupportServices. Excused Absences An un-excused absence will result in a grade of zero on that particular missed activity. Any excused absences (illness, religious holidays, athletic meets, etc) must be brought to the instructor's attention as soon as possible (not at the end of the semester). Valid documentation must be shown to support such claims. For more information on university policies on teaching, see http://www.gwu.edu/~academic/Teaching/main.htm. Academic Dishonesty Cheating compromises the integrity of our course and is unfair to those students who earn their grade through honest hard work. We have a zero-tolerance policy regarding cheating. Any dishonest behavior, once discovered, will be penalized fullest according to the GW Code of Academic Integrity. It states: Academic dishonesty is defined as cheating of any kind, including misrepresenting one's own work, taking credit for the work of others without crediting them and without appropriate authorization, and the fabrication of information. For the remainder of the code, see http://www.gwu.edu/~ntegrity/code.html. Security In the case of an emergency, if at all possible, the class should shelter in place. If the building that the class is in is affected, follow the evacuation procedures for the building. After evacuation, seek shelter at a predetermined rendezvous location.

Dear Faculty, Staff and Students: The Department of Physics at George Washington University is dedicated to ensuring that students have the best academic experience and get the most out of their education. In order to accomplish this, it is essential that we adapt teaching and learning styles to the ever-changing world. In the Department of Physics, we do this by analyzing and researching different ways of teaching; what works best, what elicits enthusiasm in students, and how these techniques translate into academic achievement. We conduct ongoing analyses of instructional methods by examining enrollments in physics courses, and by reviewing the grade trends and the valuable survey responses from faculty, staff and students. This research is limited to the review of records, both present and past. We will not request additional effort to be submitted by any member or student of the Department of Physics. You will not be asked to take additional exams, to complete surveys beyond those usually employed or to carry out any supplemental work in order for this research to take place. No analysis is done with any particular single individual in mind. All analyses are done in an aggregate manner and no identifying information will be published or presented. If you do not wish to be included in such research, please contact Prof. Raluca Teodorescu (rteodore@gwu.edu) to express your desire to decline participation in such research. Thank you for your continuing support in our educational growth and development.
