Assessement: Examinations requiring students to demonstrate a satisfactory level of achievement of the course objectives will be used to determine if the primary general education goal of this course has been attained. These goals will be assessed by student participation in class discussions and laboratory activities and written laboratory reports. The outcomes for the course will be assessed at intervals by tests and laboratory reports and by a comprehensive final examination.
Policies and Procedures:
A. Grades: The grades in all physics courses will be as follows:
A
90-100
superior
B
80-89
above average
C
70-79
average
D
60-69
below average
F
0-59
failing
Students will not be allowed to register for physics courses on an AUDIT basis. The grades in physics courses will be determined according to the following:
Homework and Participation
10%
Tests (3)
50%
Laboratory
20%
Final Exam
20%
Failure to take the final exam will result in a grade of F for the course. In the case where the final exam is missed and the instructor has been notified in advance, at the discretion of the instructor, a grade of I may be given. However, the make?up final must be taken within two weeks after the regularly scheduled final and may be more difficult than the regular exam.
B. Attendance: Attendance at all lecture and laboratory meetings is expected. Persistent unexcused absences exceeding 20% of the meetings may result in the removal of the student from the course per division policy. (Consult the Division Policies section of the Student Handbook, especially section E.1.)
C. Tests: Test questions will come from the lectures, textbook, homework problems and lab. Make-up exams will not be given; if you know you will miss an exam due to circumstances beyond your control, you can arrange to take the exam early. If you miss an exam with a valid excuse, your grade on the final exam will be substituted for that exam. If you miss more than one exam, or if you miss an exam without a valid excuse, you will receive a zero on that exam. Test scores may (or may not) be scaled up at the instructor's discretion. No test grades will be dropped.
D. Homework: Physics is learned by doing, not watching! You must work problems and read the text consistently to succeed in this class. You will be given homework after virtually every class. Homework will not be turned in, but will be checked daily for completion, and unless you do the homework, you will not pass the course. Time will be taken each day to answer questions from the previous day's homework.
E. Laboratory: There will be no make?up labs except in extreme circumstances. You will receive a zero for any lab you miss, and the lowest lab grade will be dropped.
F. Cheating: Cheating on any assignment will not be tolerated. If you cheat on a test or the final you will earn an F for the course. Other incidents of cheating will be dealt with severely. Understand that cheating is receiving or giving unauthorized aid. Students are expected to abide by the policies for academic integrity contained in the Student Handbook, see especially paragraph C(2) of the Conduct and Discipline section.
ADA Statement
In compliance with the Americans with Disabilities Act, students are encouraged to register with the Office of Student Disability Services for assistance with accommodations. It is the student's responsibility to self identify with the Office of Disability Services in order to receive accommodations. Disability Services is located in the basement of the Wood Campus Center, Room 122. Only those students with official documentation from the Office of Disability Services will receive services.
Equal Opportunity Statement
Volunteer State Community College is an equal opportunity Affirmative Action Educational Institution. No person shall be excluded from participation in, be denied the benefit of, or be subjected to discrimination under any program or activity of the College because of race, color, national origin, age, or handicap. The College also complies with the Age Discrimination in Employment Act of 1967, as amended and with the Vietnam Era Veterans' Readjustment Act of 1974.
