Intended Audience for This Course: This is a two-semester, non-calculus based physics course intended for majors in biology and other sciences, excluding math, physics, or engineering. Generally it is not taken by liberal arts students to satisfy the natural science requirement.

 

Prerequisites: A college-level math course, and a working knowledge of algebra and trigonometry.   If you are uncertain if you are properly prepared for this course, please discuss it with me.

 

Required Texts and Equipment:

 

Physics – Principles With Applications (6th ed.) by Giancoli is the required text. We will cover chapters 1à15 in PHYS 243. You are also required to have a scientific calculator without wireless connections or physics formulas included, which should be brought to all recitations, especially to exams. Programmable calculators or those with wireless capabilities are not permitted in the Testing and Tutoring Center, which will be used for multiple-choice tests.

 

Mastering Physics:  (http://www.masteringphysics.com/)  All recitation assignments will require access to the Mastering Physics problem solving system.  You may purchase access with the text or separately.  The Mastering Physics registration cost covers PHYS 243 and 245 for two years.  Problems worked on MasteringPhysics are preparation for the recitation sections.  MasteringPhysics counts 9% and the recitation grade counts 9%. There are three different sections depending on the day your recitation meets. The class codes is

PHYS243S2012

 

Each week’s recitation assignment must be completed by 9:30am on the day your recitation meets.  If you miss the deadline a penalty assessed on solutions based on the number of days late. The maximum penalty is 50%.  You may work with other students on the problems but it would be cheating if another student actually entered answers for you. MasteringPhysics is also used for quizzes after most of the 34 units. These quizzes are worth a total of 6% and you may not get help from other students on the quizzes.

 

Computer Equipment:  The hardware and software requirements for using Blackboard are available on the course site. The course notes are in powerpoint so if you don’t have that software you will need to download a free reader. There is also a version of the notes in PDF format with a script if you can’t use powerpoint.  Contact me immediately so we can work out any problems.

 

Grade Calculation:There will be three in-class tests and 3 multiple choice tests during the semester and a comprehensive final. Except for the final, multiple choice testing will be done in the Testing and Tutoring Center (Room 2 of Science and Technology 1).

Final Exam: The final exam is scheduled for May 5. The final exam will be comprehensive covering all chapters. There will be extra emphasis on chapters not covered on any of the tests. The final will include worked-out problems and multiple

choice.

Tests: During the semester, there will be three in-class tests and three multiple-choice tests for a total of 6 tests. The lowest two test grades will be dropped..

 

Comprehensive Final 24%
Tests (best 4 out of 6 counted, 13% each) 52%
Recitation 9%
MasteringPhysics 9%
Unit Quizzes 6%

 

Since the lowest two test grades (out of six) will be dropped, no rescheduled in-class tests will be allowed for any reason.  Consideration will be given for missed multiple choice tests for well- documented excuses. Since the multiple choice test will be available for about a week, there are likely to be some penalties attached to most late tests even with an excuse. It is important that you be on time for in-class tests since it will be difficult to give extra time if you are late. You must take tests and the final exam in the class you are registered in.

 

The lowest recitation grade will be dropped as well as the lowest MasteringPhysics recitation assignment grade. The lowest three of the Unit Quiz grades will be dropped

 

In the event of an unforeseen school closing on a test day, the test will be given at the very next lecture session after the university reopens. If the weather forecast indicates a strong possibility of heavy snow, hurricane etc., I might decide to postpone the test until the next class day. The course Blackboard page will have any announcements posted as soon as possible.

 

Tests and Exams:The tests in this course will be multiple choice and free-form problems. Equation lists will be provided for the final exam and all tests.

 

In-class Tests:  The in-class tests will be given during the recitation periods. Will consist of about three free-form problems with multiple parts.  Each problem requires a complete solution starting from basic formulas and with all steps shown.  Free-form problems will be similar to recitation problems, examples worked in class, problems from old tests and examples from the book. The exams will test both your understanding of concepts as well as your ability to solve problems. Time is likely to be a factor for many students, so you must budget your time carefully on tests.

 

In-class tests will be shown to students at the start of the next recitation or during regular office hours.  I will collect the tests after you have reviewed them.  You are encouraged to review each test when you receive and request a re-grade of the specific problem if you think that a grading mistake has been made. This request must be made in writing on a separate sheet of paper and include a signed pledge that you have not written anywhere on the test.  Also, since memories fade as to how much credit was taken off for a particular mistake, any request for re-grades must be made within three weeks of the first day the test was returned.  It should be remembered that a re-grade could result in a lowered score, especially in the case of frivolous requests.

 

Multiple Choice Tests in the Testing and Tutoring Center: Because the class is only 50 minutes, I plan to give the multiple choice tests in the Testing and Tutoring Center.  To take at test you must have access to the Blackboard 9.1

Learning System.

The username and password is the same as your GMU mail account.  A schedule of times when each multiple choice may be taken will be posted on the website.  You will have about a week to visit the center and take the test.  Each lecture class

will have a different deadline.  Students who miss the deadline will usually not be able to take the test.  If you are permitted, there will likely be a penalty.

 

The questions will be randomized to make cheating difficult.   Paper is limited in the center and only non-programmable calculators without wireless capabilities may be used.  If technical problems occur at the testing center, I reserve the right to make adjustments to the way I handle the multiple choice part of the tests.

 

Students are expected to bring a Scantron Form 882E (green) to the final exam.  Please put your name as it appears on the roll (first name followed by last).  The time for taking a test is limited, so you must stop writing when told to do so. The scantron must be finished by this time or you will be penalized 2%.

 

Academic Integrity:  . You are expected to observe the GMU Honor Code on tests and exams. Cheating on exams will be dealt with very severely. It can even result in your dismissal from the University.  There should be no communication of any kind between students during tests and exams.  If you don’t understand a question, please ask the instructor.

 

While taking the multiple choice test in the Testing and Tutoring Center you may not view any web page other than the test.  You may not talk to anyone or look at any materials on the computer, in your calculator or on paper.  Anyone doing this will be turned into the Honor Council for cheating.  It is important that you know that the center uses software that allows the monitor to view and save the screen of any computer in the center.  It is cheating to pass any information about the test given in the Testing and Tutoring Center to anyone else in any form.

 

Recitation:   ALL STUDENTS REGISTERED FOR THE LECTURE MUST ALSO BE REGISTERED FOR ONE OF THE RECITATION CLASSES. RECITATION IS MANDATORY. Students must attend recitation sections for which they are registered unless they have permission. Your recitation instructor will discuss the grade components (quizzes, class participation), which will make up your recitation grade.
