Diversity In The Classroom: It is the responsibility of the instructor and the student to foster and maintain a harmonious, nonthreatening and non-discriminating environment in the classroom. Although students are encouraged to express their ideas freely, an instructor must be vigilant against any inflammatory and demeaning statements or arguments (in classrooms) that may promote hate toward people, beliefs, and ideals. Zane State College is committed to follow a non-discriminatory policy and accepts diversity as part of the community environment. Therefore, all individuals regardless of their ethnicity, beliefs, age, gender, and life style, are to be respected as equal and contributing partners of our society. Free Tutoring Services: I am available most mornings before school. Please take advantage of this. Be proactive.

Note that the final exam is comprehensive, i.e., it covers everything since the first day of the course! Makeup exams will only be granted in extreme situations.. Quizzes: There will be short quizzes at least two times a week, except on the first day of class, and the days of the exams.

10 90 % 100% A 80 % 89 % B 70 % 79% C 60 % - 69% D Below 60% F NOTE: If students fail to take the final exam, their final grade for the course will be an F, no matter their final course average. PROCEDURES: Calculators: It is required to have a TI-83 or TI-84 graphing calculator. NOTE: A TI-89 calculator or any other calculators beside the TI-83 or TI-84 are NOT permitted in this course! The use of calculators will be permitted on some quizzes and exams. Please note that there will be non-calculator quizzes and non-calculator portions of exams. Borrowing calculators from fellow students during exams and quizzes is not permitted. Also, the student is responsible to understand his/her own calculator. Refer to the manual. Electronic Devices: Electronic devices including cell phones, computers, tape recorders, IPods, etc. must be turned off and out of sight. They are not to be used in the classroom for any reason, without the permission of the instructor. Deliberate violation of this policy could result in removal from the course. Instructor's Responsibilities: The role of the instructor will be to explain new material and review previous material when questions are raised by students after attempting to do the material as an outside assignment. Student's Responsibilities: The student's responsibilities are a major consideration in this course. After material has been discussed, it is the student's responsibility to complete the outside assignment(s) prior to the next class meeting so that material that remains unclear may be re-explained. In addition, the student is expected to read through the new material that is scheduled to be presented so that the material will be generally familiar and so that preliminary questions may be asked. Attendance Policy: Although there is no official attendance grade for this course, students are expected to be on time for class and to remain for the entire duration of class. Students who miss class are responsible for finding out from a fellow student what was covered in class and what assignments they missed. It is not the instructor s responsibility to students what was covered in class on a day which they missed, or to re-teach the material taught in class that day. If students are late for class and the daily quiz has been given, they must re-take the quiz at another time as one of their Page 10 of 11

11 three makeups. Please keep in mind that there is a direct correlation between class attendance and success in the course. A student s grade tends to suffer significantly when class is missed. Make-up Policy: Make-up exams may or may not be given at the discretion of the instructor. The instructor may allow students to take makeup exams if the following procedures are followed: 1) The instructor has time to administer makeups. 2) The student notifies the instructor prior to the exam, giving a justifiable reason for the absence. 3) The instructor feels that the reason is valid (proof may be requested) 4) Emergencies will be evaluated on an individual basis. NOTE: IT IS THE STUDENT'S RESPONSIBILITY TO PERSONALLY SEE THAT THE INSTRUCTOR IS NOTIFIED PRIOR TO THE EXAM. Major exams missed by the student may be taken within the next three college class days if the student presents an explanation to the instructor in writing. It will be up to the judgment of the instructor if the explanation seems valid. Make-up exams may be given full or partial credit based on the validity of the absence. To take a written make-up, a photo ID must be shown. Students who do not take make-up exams by the deadline forfeit the opportunity. Please note that a makeup final exam must be approved by the dean of Business and Engineering Technologies (see exam section above). Also, students are only allowed three makeup quizzes (see quizzes section above). Academic Dishonesty: Academic dishonesty will not be tolerated. A student, whether a helper or recipient, will receive a ZERO on any assignment for academic dishonesty. Page 11 of 11
