Course Logistics:

READING and HOMEWORK assignments will be provided “on-line” using the TYCHO homework system. You will be provided a username and a temporary password to access your assignments. All of the homework for the entire term has been generated. Check the online page regularly for assignment updates.

It is assumed that you have read the assigned material by the due date. The reading assignments (Pre-Chapter Homework) consist of about 10 multiple-choice questions based upon the reading from the assigned chapter. Each assignment must be submitted at 11:30 AM on the due date unless otherwise announced. Once the cut-off time has elapsed, you will not be able to submit that Pre-Chapter Homework assignment or any changes to that assignment.

In addition to the Pre-Chapter Homework described above, short in-class exercises are used to monitor conceptual understanding. (See CLICKERS.) These can typically be answered by keeping up with the reading assignments and class discussions. These are designed to surface possible misconceptions and uncover some of the common pitfalls that confuse many students.

Problem-solving assignments (Post-Chapter Homework) will be due according to the dates listed on the assignment web page. These assignments typically consist of about 10 (including 2-4 self-tutoring) online exercises/problems and are due at 11:30 PM of the date shown. Check the web page for the exact due dates. In general, these assignments involve a numerical answer and may be printed for off-line completion if you desire. You may return to the computer to enter your answers or ask for additional assistance. Up to 10% extra credit is given for all exercises/problems completed before the 48 hours prior to the cut-off time on the due date. Those exercises/problems submitted within 48 hours after the cut-off time of the due date receive 50% credit. After 48 hours beyond the cut-off, you can no longer submit answers to exercises/problems for credit.

Be aware that it is very important that you make an honest attempt to work the problems since doing the homework is a primary technique for learning the material. It is also very important that you be able to understand the solutions conceptually rather than just memorizing formulas since the exam problems generally require you to demonstrate applications of the concepts being assessed.

EXAMS will consist of three “1-hour” exams and a “2-hour” comprehensive final exam. The 1-hour exams typically consist of 5 problems and are worth 100 points. The problems are related to homework sets, sample problems from the text and examples worked in class or the laboratory. The 2-hour final exam will be multiple-choice standardized test. All exams are closed book and closed note. However, you will be provided with a sheet of “possibly useful information” with formulas, universal constants, conversions, etc. for all exams.

QUIZZES consisting a few short questions based upon material covered in the previous chapter may be administered on occasion with warning or without warning. These short exercises/problems are used to monitor conceptual understanding. Quiz questions are typically in a multiple–choice format and answered with a few short lines of algebra or explanation.

CLICKERS need to be purchased by each student. The system will allow you to further interact with the instructor during the lecture. You will be able to respond to questions and give feedback as the course progresses. Responses are recorded and scored. The scoring is used to measure class participation and can be used to determine grades in borderline situations. As stated above, these are designed to surface possible misconceptions and uncover some of the common pitfalls that confuse many students.

PARTICIPATION in the course can have a reflection in the overall final grade. Items such as attendance, attitude, sincerity, changes in performance, etc. will be considered in borderline situations.

LABORATORY sessions meet once per week and are required for this course. The laboratory section is designed to provide you with hands-on experiences related to the topics that are discussed during the lectures. Most of the laboratory handouts come from the laboratory manual that you need to purchase. Handouts are provided for the other sessions. During the lab, you will make predictions, answer questions, and record observations. Laboratory homework assignments are to be completed during the session and submitted by the end of that laboratory session. Only officially stamped work will be accepted for credit. Each lab is graded in two parts: 1) completion of the requirement measurements and “in-lab” questions and 2) completion of the laboratory homework. Each piece is worth 50% of the total grade for that lab.

WEB-PAGE:

http://www.cod.edu/people/faculty/fazzinid/PHY2112/PHYS2112.html

Monitor this site for important announcements and course updates such as reading and written homework assignments. This site is updated on a regular basis.

GRADING is tentatively based on the following breakdown:

Pre-Homework:	10%	A:	> 90%
Post-Homework:	10%	B:	> 80%
Laboratory:	15%	C:	> 70%
Quizzes/Clickers	5%	D:	> 60%
3 Hourly Exams:	12% each	F:	< 60%
Final Exam:	24%

Depending on other factors involved with the course, it is possible for

the grade cut-offs to be lowered by up to 5%, but do not count on it.

_______________________________________________________________________

Miscellaneous:

LATE MATERIAL & MAKE-UPS:

All quizzes, labs, and exams must be completed on the scheduled date at the time they are scheduled. There are no make-ups for any reason. If absent for a “one-hour” exam, then the score of the final exam will be applied to one (and only one) missing exam. All laboratory homework must be submitted at the beginning (1:00 PM) of the due date to receive credit. Any lab submitted late can still receive up to 50% credit from the completion of the data acquisition and “in-lab” questions as long as it was officially stamped by the instructor and submitted before that particular lab is returned to the class.

CALCULATORS:

Students may use their own calculator during exams. There is no sharing of calculators during exams and NO CELL PHONES CALCULATORS may be used during exams.

WITHDRAWAL POLICY:

Students may withdraw from the class without instructor permission anytime through Monday, October 17, 2011. Students who have missed 5 or more classes or labs AND are not passing with a grade of “C” or better by Monday, October 17^th, 2011 will be considered in “non- pursuit” and dropped from the course by the instructor (NO REFUND!). The last day to drop from the class with instructor permission is 48 hours after the return of the second exam.

INCOMPLETE POLICY:

Under extraordinary circumstances (such as an extended medical emergency or family tragedy) a student currently earning “C” or better may not be able to complete all of the course requirements. In such instances, the student may petition the instructor for an “incomplete” grade. Only if the instructor deems the request as warranted will a contract agreement be made between the student and instructor as to how the course will be completed. After the contract is signed by both the students and the instructor, the student will receive a grade of “I”. Note: The course must be completed with the same instructor and within one calendar year of the end of the term for which the student was enrolled.

If the student does not complete the requirements for the course as prescribed in the agreement, the “I” grade will automatically revert to a grade of “F.” It is advised that the students be fully aware of the consequences of receiving an incomplete grade and understand the terms described in the COD Catalog, p. 91: Grade of Incomplete.

CONDUCT:

Anyone caught cheating or plagiarizing will receive an automatic failure for the course. You will not be allowed to drop the class if you are found in violation of this section. It is expected that you are aware of and follow the guidelines for conduct as described in the COD Catalog, page 98-99: Student Code of Conduct (Board Policy 20-35).

DISRUPTIONS:

The proprietor of any cell phone or pager that is heard to go off in class or the laboratory ensure themselves a "0" on the next homework assignment. Disruption during an exam will result in a 5-point deduction off that exam score (10 points during the final exam).

Individuals that exhibit disruptive behaviors that interfere with the lectures and/or laboratory sessions will be removed from the class so that those individuals who wish to learn physics can do so. Those individuals removed must then conference with either the Dean or an Associate Dean in Natural & Applies Sciences Division. Those individuals may then rejoin the class pending the outcome of the conference.
