Course Procedures             

 

A. Materials

  1. Textbook : University Physics(12th edition) by Young and Freedman

  2. Calculator(a simple scientific calculator)

 

B. Special notes: (tentative)

  1. Test 1 covers chapters     1,2,3

      Test 2 covers chapters     4,5, 6,7,8

      Test 3 covers chapters     9,10,11,12,13

      Final exam covers all  Chapters .

   

   2. If the final exam grade is greater than the lowest houry exam ,it will be worth     

      50% and the lowest hourly exam will be dropped.

    (no make up tests will be given)

 

  3. Computer projects must be turned in on time.

 

 

 

 

C  : EXAMINATIONS:

      There will be 3 major exams given  in advance during the semester.  No

       make-up exam will be given .  Absence from these exams will result in a zero grade.  A comprehensive final will be administered during final exam week. This is a requirement of the course. Exam Questions will be asked from deductive reasoning from the material presented in Class, Home Work and Reading assignment.

      Students can bring a simple scientific calculator for the exams.

      Cell Phones/Palm pilot or any other electronic devises of any kind will not be allowed during the exams .

 

HOMEWORK:

 

Homework assignment will consist of:

 

1 .   Reading sections in the text

 

2.   Answering questions

 

3.    Problems

 

           It is essential for students to do assignments on a daily basis.  Selected problems will be discussed in the class as time and demand permits.  The reading assignments are made in advance of the lectures that cover the reading material.  The lectures are designed to reinforce the students reading not for the students to learn the entire course from the lectures. It is extreamly important for the students to carefully and perceptively read the assignments before the lectures. Some elementary material that needs little explanation will be assigned for reading and not covered in the class.

 

COMPUTER PROJECTS:

 

            Report should be done neatly.  Late reports will not be graded.

 

PREPARATION AND PREREQUISITES:

 

           Students are required to have completed the appropriate prerequisits Math/Physics courses or their equivalent to be enrolled in a course.  Students who have not completed the prerequisite courses are ineligible for enrollment in a course and will not be given a final grade if they do not withdraw.  Students should either be concurrently enrolled in the required Math course or have completed it or an equivalent course.  Students are required to have a working knowledge of the topics involved in the prerequisite courses   and all their prerequisites at least at the level of having passed the  courses at the B level.  If the student feels insecure in his/her depth of knowledge in these areas it is recommended that he/she immediately undertake a brief but thorough review of these subjects in lectures, but the student will be responsible for knowing the material. All the exam problems will be similar to the homework assignments, the example problems in the book or example problems worked out in the lectures.

 

 

 

  

C. Tentative test dates: 

        

         Test 1 ( 9 /18/2008)

         Test 2 ( 10 /30/2008)

         Test 3 ( 12/4/2008)

         Final Exam ( 12 /9/2008)  

 

COLLEGE POLICIES FOR COURSE SYLLABI:

 

ESSEX CODE OF ACADEMIC INTEGRITY

 

Academic honesty is expected of all students.  Work submitted by students as their own must be their own and materials taken from any other source must be clearly identified as such.  Falsification of data, plagiarism, copying from others in class, obtaining advance information about exams, and other violations of academic honesty are not acceptable.  The usual penalty for academic dishonesty is failure on the paper or exam or failure in the course, as determined by the instructor.  The instructor may recommend a more severe penalty, such as dismissal from a program or from the College.

 

ESSEX WRITING POLICY

 

The college recognizes that clear, correct and concise use of language is a characteristic of an educated person.  Instructors should consider the quality of writing in determining a grade for a written assignment.  In some instances, poor writing can be a sufficient cause for a failing grade on a paper, and in extreme cases, a failing grade in a course.

 

ESSEX ATTENDANCE POLICY

 

All students are expected to attend class regularly and punctually in order to derive maximum benefit from instruction and to contribute to learning in the classroom.

 

Each faculty member will determine the specific attendance policy for each course and will monitor attendance accordingly.  At the faculty member’s discretion, absence from class may be the basis for academic failure.

 

 

Students are encouraged to seek help from their instructors whenever they encounter academic difficulty (either during scheduled office hours or by appointment).  In addition, the Student Success Center in E312 has information about free tutoring provided.  Stop by or call for more information (410-780-690).

 

 

 

SNOW AND EMERGENCY CLOSING POLICY

 

Should it become necessary for the College to close or alter its times of operations, announcements will be made after 6:30 a.m. on WBAL radio (1090 AM) or you can call 410-682-6000.  Should the College’s opening be delayed, faculty and students are expected to be where they would normally be at the announced opening time.
