The lowest quiz score will be dropped. 2% each, 10% total. Homework (selected homework problems will be graded). 10% total. Class participation 5%. Students will be required to ask a question, answer a question or present a homework solution at each class meeting. Final grades will be assigned as follows: 90 – 100% A 80 – 89% B 70 – 79% C 60 – 69% D Below 60% F HOMEWORK: Homework will be assigned in class. Successful independent completion of the homework assignment serves as an invaluable aid in understanding the concepts presented in the course. Students should be prepared to present homework solutions in class on the due date. Selected problems will be graded by the instructor. See course outline. ATTENDANCE POLICY: Attendance will be taken at each class session. Each student is responsible for any and all announcements, assignments, lectures, materials, handouts, and scheduled exams presented during the class session. Poor attendance will adversely affect the class participation grade. AUDIT AND WITHDRAWAL POLICY: Students are reminded to consult the College Catalog for dates, procedures, responsibilities and impacts of changing registration status. November 5 is the last day to withdraw from a course or change from AUDIT status to CREDIT status or from CREDIT to AUDIT. Change from credit to audit status requires a written contract between the student and instructor. The contract must be in place prior to November 5. Students who fail to adhere to the terms of the contract will receive a grade of WD. MAKEUP EXAM POLICY: Makeup exams will be allowed without penalty for legitimate reasons if the instructor is notified in advance or if an emergency occurs. Quizzes will be available online at the course WEB-CT site as scheduled by the instructor. All quizzes must be completed within the time allocated. All makeup exams will be administered in the instructor’s office or in the Testing Center and will be scheduled by the instructor. STUDENT INTEGRITY POLICY: Students are expected to perform independently on exams and quizzes without the use of unauthorized materials (unauthorized notes, etc.). Any violations of the Student Code of Conduct as outlined in the Student Handbook result in a score of zero for the exam or quiz. The violation will be reported to the Director of Student Affairs and to the College Judicial Committee for review and possible disciplinary action. DISABILITIES AND SPECIAL NEEDS: Students with disabilities who believe they may need accommodations in this class are encouraged to contact Disabled Student Services in the Learning Assistance Department at 301.934.7614 as soon as possible to better ensure that such accommodations are implemented in a timely fashion. UNAUTHORIZED PERSONS: Unauthorized persons (children, friends, family members, and any other persons not registered for the course) are not allowed in the classroom. Details of this college policy can be found in the Student Handbook. DEPARTMENT EXPECTATIONS: In order for you to be successful in your physics courses, the mathematics, physics, and engineering faculty has developed the following common expectations of all students in physics courses. 1. As a student, you need to take responsibility for your own learning. This includes, but is not limited to: Arriving on time for each class Staying for the entire class and not leaving class early Actively participating in class and not sleeping or putting your head down Not engaging in other activities that detract from the classroom learning experience Bringing the required materials to class. These might include textbooks, notebooks, binders, pencils, pens, and calculators. Taking care of all business (phone calls, bathroom breaks, getting food, drinks, things from cars, etc.) before class starts. 2. You are expected to be an active learner in the classroom as well as out: to participate in group discussion, ask and answer questions, and work problems at the board. 3. You are expected to study your textbook, not merely work problems from it. The best way to do this is to read the section to be covered before the lecture is given, listen to the lecture and take notes, and then study the text again before tackling the practice problems. If this seems like a lot of work, remember that you need to allot 2 hours outside of class for each hour in class. This time commitment increases for online, web-hybrid, and computer-assisted classes. 4. There is no substitute for continued and ongoing studying and doing homework problems. The best way to learn physics is to do physics. 5. It is your responsibility to keep your homework up-to-date. If you are having difficulty with the course material, then you need to take action right away – do not wait until you have lost all hope! There are several options to get assistance: Talk to your instructor during office hours. Visit the student success center on campus. Tutors and hours are available at www.csmd.edu/StudentSuccess/Tutoring/ Use online tutoring available at www.smarthinking.com 6. Realize that college level physics can be hard and is not always fun. 7. You are given the means to keep track of your grade and are expected to take responsibility for knowing your grade status throughout the semester. 8. Learning physics is different from learning some other subjects. In a physics course, you must be able to do four things: a. b. c. d. Understand the material. Process the material. Apply what you have learned to solve a problem correctly, and Remember what you have learned in order to learn new material. 9. Another reason that learning physics is different from learning other subjects is that it follows a sequential learning pattern, which simply means that the material learned on one day is used the next day and the next day, and so forth. This building block approach to learning physics is the reason it is difficult to catch up when you fall behind. 10. College physics courses cover twice the material in the same time frame as do high school physics courses. Faculty members have a certain amount of material to be covered each semester. They have to finish certain chapters because the next course is based on the information taught in this course. Improve your study skills so you can keep up! 11. Most of the exams and quizzes are timed and many students think that they will run out of time. Most physics problems involve the application of the laws of physics and the expression of these laws in mathematical terms. Students not only must understand how to apply the physical laws but also must use mathematical principles well enough to complete the problems with enough speed to finish the test. 12. During the first few days of class, do not take the attitude that “I already know this material” and start to slack off by not taking notes or not completing homework assignments. Good study habits start from the first day of class. Start practicing good study habits now while the material is familiar to you. In that way, those habits will already be a part of your routine when the material becomes more challenging. 13. Take pride in your work and never let yourself fall into the trap of believing that you cannot do physics. Virtually everybody can, if he or she is willing to work hard enough. Be persistent and determined in your work.
