A 10-point grading scale will be used:  A = 90-100, B = 80-89, etc

 

EXAMS:

 

THERE ARE NO MAKE UP EXAMS OR HOMEWORK. IF YOU MISS AN EXAM DUE TO REASONS BEYOND YOUR, CONTROL, IF THE REASONS ARE FOUND LEGITIMATE THEN MISSED EXAM GRADE WILL BE REPLACED BY YOUR FINAL EXAM GRADE. THIS APPLICATION CAN BE DONE ONLY ONCE. IF YOU HAVE TO MISS AN EXAM BECAUSE OF ILLNESS OR OTHER CIRCUMSTANCES BEYOUD YOUR CONTROL, NOTIFY THE INSTRUCTOR BEFORE THE EXAM.

 

WEBASSIGN (ONLINE HOMEWORK SYSTEM):

You are encouraged to work together on homeworks. You must acquire a WebAssign access code. You will be doing your homework online and it counts 20% towards your grade. The access code can be purchased at the bookstore or online. You can use a computer in the library to do your homework, if necessary.

 

To register you will need the following information:

  • Your username is the same as your 49er Express username: 8000…
  • Your full name is your family name
  • Your institution is: UNCC
  • Your initial password is your first name (Capital first letter)
  • Then go to: https://www.webassign.net/student.html

and follow the instructions on the screen.

 

Additional information can be found at

 

EXTRACREDIT FOR ANSWERING QUESTIONS DURING THE LECTURE

You are encouraged to answer questions during the lecture. You will receive 3 points for a correct response, 2 points for partly correct answer, 1 point for participation. Your points will be added to your weekly WebAssign grades by the instructor. Each week you are encouraged to answer no more than 2 such questions in class.

 

DAILY QUIZZES:

You will receive 3 points for a correct response, 1 point for an incorrect response, 0 points for no response. Total quiz points will be scaled to a 100 point scale. You will use your PRS clicker to participate in daily quizzes.

PRS Personal Response System (Your Clicker)

All students in the course must have their own clicker. You must register your clicker online. You must use an ON-CAMPUS computer to access the registration website (You will not be able to register using an off-campus computer).

To Register:

Enter the required information.  Your clicker ID number is inside your clicker in the battery compartment.  Please enter the Id numbers only (not the letters).

 

SUPPLEMENTARY INSTRUCTIONAL SESSIONS

The Supplementary Instructional (SI) sessions are highly recommended. The SI sessions will be conducted by Sean Hicks. Here is the schedule of SI sessions for this semester:

Monday: 12:30 – 1:45, Smith 228A

Wednesday: 11:00 – 12:15, Smith 267

Thursday: 3:30 – 4:45, Smith 269

 

CALCULATORS:  

Students will need to use a scientific calculator for homework, tests, and the exam.  Graphing calculators and calculators with memory that have the capability of storing information and PDA’s will not be permitted for use during the quizzes and the exams.

 

STUDYING THE TEXT:

For most of you PHYS 2102 will be the first course that you will apply calculus rigorously.   I strongly advise to review your calculus, trigonometry, vector algebra and basic plane geometry. The course requires at least three hours of studying for each lecture.  Keeping up with the contents covered during the semester is crucial.  If you fall behind in contents as the semester proceeds then it will be very hard to catch later on.  The key to the success is studying in an organized way and asking questions when you do not understand.  I strongly recommend group study.

 

CLASSROOM RULES:

The following  are a set of rules governing student conduct in the classroom. They represent little more than common courtesy. The continued violation of these rules after an appropriate warning can result in the student being disenrolled from the course.

1. DO NOT HOLD PERSONAL CONVERSATIONS DURING THE CLASS.

2. ALL CELL PHONES AND PAGERS MUST BE TURNED OFF DURING THE CLASS.

3. Arrive for class on time. If you arrive a few minutes late, quietly take a seat in the back of the classroom.

4. If it is necessary to leave before the class is over, inform the instructor before the class begins.

 

ACADEMIC INTEGRITY: 

You must completely do your own work on the in-class exams, and the final.  Failure to do so will be a violation of academic integrity. Academic honesty and integrity are essential to the existence and growth of an academic community. Without maintenance of high standards of honesty, members of the instructional faculty are defrauded, students are unfairly treated, and society itself is poorly served. Maintaining the academic standards of honesty and integrity is ultimately the formal responsibility of the instructional faculty; and this responsibility is shared by all members of the academic community. UNC Charlotte strives to create an academic climate in which the dignity of all individuals is respected and maintained. Therefore, we celebrate diversity that includes, but is not limited to ability/disability, age, culture, ethnicity, gender, language, race, religion, sexual orientation, and socio-economic status.

Students have the responsibility to know and observe the requirements of The UNCC Code of Student Academic Integrity (Catalog p. 275).  This code forbids cheating, fabrication or falsification of information, multiple submissions of academic work, plagiarism, abuse of academic materials, and complicity in academic dishonesty.  Any special requirements or permission regarding academic integrity in this course will be stated by the instructor, and are binding on the students.  Academic evaluations in this course include a judgment that the student’s work is free from academic dishonesty of any type; and grades in this course therefore should be and will be adversely affected for academic dishonesty.  Students who violate the code can be expelled from UNCC.  The normal penalty for first offense is zero credit on the work involving dishonesty and further substantial reduction of the course grade.  In almost all cases the course grade is reduced to F.  Students are expected to report cases of academic dishonesty to the course instructor.

•         No cell phones or other electronics at all during exams. 

•         Students with cell phones, or other wireless communication devices during an exam will have the exam taken up and receive no credit for the exam. 

•         Students will be required to show their university ID upon turning in exams.
