Total                                                                                                               100%

 

Quizzes will be administered as often as needed without any prior notice.

Grading will be done according to the usual A to F scale as following: 

90 to 100% A,    80 to 89% B,  70 to 79% C,    60 to 69% D,     59% and below   F 

No reference materials or books will be allowed in any tests or final exam 

Homework and projects will be due at the beginning of the next class period unless otherwise specified.  Late submission is allowed with the following conditions: 

30% penalty for submitting one day after the due date

60% penalty for submitting two days after the due date

80% penalty for submitting three days after the due date

No credit for submitting more than three days after the due date

No “make-up” or “extra credit” assignments will be given 

Class Cancellation Policy: 

If the class needs to be canceled, the instructor will notify students in advance and will assign numerical problems to be worked on or research reports to be prepared during the class period.  

Attendance Policy:

Regular and punctual attendance in every class is mandatory. Albany State University attendance policy states that: “All students are expected to be in class on time for all class meetings. Attendance begins the first day of the class and all students are expected to remain in class for the entire class period unless prior arrangements have been made with the instructor. Absenteeism cannot exceed the credit hours for the course. This means that, for this class, a student cannot miss class more than three times during the semester.”

The penalty for more than 3 unexcused absences will result in 5 % reduction in the tabulated score for calculation of final grade. More than 4 unexcused absences will lead to dismissal from the course.

Attendance will be taken at the start of each class session. If you are not present when attendance is taken, you will be counted absent for that day.  For an absence or a tardiness to be excused, you must inform the instructor ahead of time. If you indeed have to miss a class due to unavoidable circumstances, you are responsible for all the announcements and materials presented in the class. Do not expect your instructor to repeat the topics that you have missed. All quizzes and tests are to be taken at the scheduled time. No makeup examination will be given unless extenuating circumstances exist. Absence from an examination will result in a grade of ‘0’ for that examination.

Class Disruption Policy:

1.        Cell phones must be turned off or put in the vibration mode during class or tests

2.        You must leave the class room to answer the cell phone calls

3.        Cell phones cannot be used during the class for text messaging

4.        Cell phones cannot be used during the tests or final examination in lieu of calculator

5.        Use of beepers, pagers, radio or earphones are not permitted during the class or tests

6.        Unauthorized use of computers in the lab (such as web surfing, e-mail communication or watching/creating Facebook) will not be permitted

7.        Violation of any of the above will result in a 10 point deduction from the tabulated score for calculation of final grade 

Eating or drinking is strictly not allowed in classroom or laboratory 

Academic Dishonesty Policy:

It is illegal to falsify and/or otherwise misrepresent oral and/or written communications by the instructor. There are many items that fall under this category which may include but not limited to the following:                                       

i) Statements concerning dates assignments are due

ii) Signature requirement

iii) Bonus opportunities

iv) Changes in course assignments

v)  Changes in grading protocol. 

The intentional and/or otherwise misrepresentation(s) or erroneous disclosure(s) of information presented in the classes, lectures, labs and /or other consultations for personal gain represents unethical behavior and/or academic dishonesty in an attempt for personal gain. Such behavior(s) may possibly represent slander, and/or libel, and/or defamation of character which may possibly have legal ramifications. Please refer to the student handbook for guidelines in reference to this issue.

Students are encouraged to ask questions and consult each other while working on their assignments.  However, sharing the work electronically or copying another student’s work by any method is strictly forbidden.  If two or more students are found to share the same copy of a project, each will receive a grade of ‘0’ for that project.  This penalty applies even if other students copied a student’s work without his/her permission.  Therefore, it is very important that you safeguard your work, whether in printed or electronic form.            

Repeat offences will lead to dismissal from the course.

 Anyone caught cheating in a test will receive zero in that test. Second offense will be reported to the authorities and the student will be expelled from the course.

University Writing Requirement:

Writing is integral part of teaching and learning in all disciplines. Writing activities such as class project, lab report, test and quiz in this course may be evaluated for correct grammar and spelling. All handwritten statements have to be legible. Points may be taken off for grammatically incorrect statements or bad handwriting.

  Sexual Harassment, in any form, is not condoned by Albany State University or the University System of Georgia
