Classroom Response System: We will be using a system called "iClickers". Each student must buy an iClicker ( $40 at the bookstore) which can be sold back at the end of the semester or possibly used for other courses. Students are responsible for taking care of it and bringing it to each class.
Each student must download weekly homework problem assignments from the University of Texas homework system and submit the solutions online before each assignment is due. Late work will not be accepted. In general, you will have about a week after homework is assigned to finish and submit it.
University of Texas Homework System: We will be using the improved version of the UT homework system, called Quest. Each student must obtain or can reuse an existing UT EID and password and also sign up for the course itself using the course number provided by his/her instructor. Homework assignments will be posted online in Quest. Students login, download assignments, solve the problems, and submit answers to the automated grading system.
Web Sites: Instructor will use http://web.njit.edu/~cao/106.htm for posting lecture notes, problems, exam results, study materials, etc. So go there often.

A final letter grade could be assigned as follows, but could be adjusted depending on the class average:
Common Exams : Three common exams will be given during the semester. The schedule is:
Common Exam 1 : Friday, February 18, 8:30 - 9:45 am
Common Exam 2 : Friday, March 25, 8:30 - 9:45 am
Common Exam 3 : Friday, April 15, 8:30 - 9:45 am
Final Exam: A comprehensive examination of the entire semester's work will be given during Finals Week at the end of the semester.
Workshop: Workshop instructor will report attendance and grades to the Physics 106 instructor who will include the workshop evaluation in the final grade.
Lecture/Recitation Quizzes: Short quizzes covering the preceding week's work will usually be given during each lecture. The grades count toward your final course grade . There will be no make-up quizzes.
Homework: Homework assignments will be posted on-line at University of Texas Homework System. Each student will need to obtain UT EID to register for the class. Then students will be able to download the assignments, solve the problems and submit answers to automated UTHW system for grading. The unique course numbers are 106008 for section 008 and 106010 for section 010.
The final grades will be based on a composite score that includes each common exam score, the final exam, short quizzes, and the term's homework score. Here are the approximate weights to be used for calculating the composite score:
﹛
|
45% for all three common exams (15% each) |
|
30% for the final exam |
|
10% for the total workshop grade |
|
8% for the total homework grade |
|
7% for the total lecture quiz grade |
Here are the approximate weights to be used for calculating the final grade and the final grade scale:
|
80% and more |
A |
|
75% - 79% |
B+ |
|
70% - 74% |
B |
|
65% - 69% |
C+ |
|
55% - 64% |
C |
|
50% - 54% |
D |
|
49% and less |
F |
The Physics Learning Center, located in 401T, is staffed by faculty and specially trained Teaching Assistants. All Physics students are invited. The time it is open will be announced.
NJIT policy is zero-tolerance for cheating of any kind and for student behavior that disrupts learning by others. Incidents will be immediately reported to the Dean of Students. The penalties for violations range from a minimum of failure in the course plus disciplinary probation up to expulsion from NJIT with notations on a students' permanent record. Avoid situations where your own honorable behavior could be misinterpreted. Students will be required to agree to the NJIT Honor Code on each exam.
The weekly text, practice problem, and homework assignments are listed in the schedule below . It is almost impossible to succeed in this course without working a lot of problems
The weekly text reading are in NJIT PHYS 105/106 (Serway & Jewett). Read each assigned section before the Lecture covering the material in it. We suggest that you download instructor's lecture notes (if available) and bring them to class.
There is a set of "recommended problems" posted for on-line with solutions. These will not be graded, but they are a good way to get up to speed before doing the online homework and they are a favorite source of exam questions.
Each student must download weekly homework problem assignments from the University of Texas homework system and submit the solutions online before each assignment is due. Late work will not be accepted. In general, you will have about a week after homework is assigned to finish and submit it.
Homework scores count cumulatively about as much as one common exam toward your final course grade. Students who do not submit the homework are automatically lowering their class average by up to 8%.
Homework due dates will be announced by each instructor. They depend on the class schedule but will generally allow you at least one week-end to complete the work.
Attendance at lectures, recitation classes, and exams is mandatory. Instructors will take attendance regularly. A total of 3 unexcused absences from lecture, recitation, and workshop in any combination is regarded as excessive: the Dean of First Year Students may be notified and a student may be dropped from the course. Students with several excusable absences should contact the Dean of First Year Students. If you withdraw from the course, do it officially through the Registrar; do not simply stop attending and taking exams. Students who withdraw unofficially force the instructor to assign a course grade of "F".
Please do not eat, drink, or create noise that interferes with the work of students or instructors. Cellular phones, wireless devices, notebook computers, and messaging devices of all kinds must be turned off during class meetings and exams.
If you are having difficulty visit or email your instructor; do not simply hope for a miracle and fall further behind. The Physics Learning Center (401 Tiernan) can provide ongoing help; it is staffed by faculty and trained Teaching Assistants. The Physics Dept. office on the 4th floor of Tiernan has more information. Tutors may also be available through the Residence Halls organization.
