V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Details of the Code of Academic Conduct can be found in the Student Handbook.

VII.  Methods of Instruction

(Methods of instruction include one-on-one and/or small group discussion, and demonstration. Calculators/computers will be used when appropriate.

Course may be taught as face-to-face, media-based, hybrid or online course.

VIII. Course Practices Required

The course is taught utilizing a classroom instructor and an interactive computer website. Course participants must attend scheduled class hours as well as one computer lab hour per week. Each course is divided into five modules. Each module must be completed with a minimal posttest score of 70% to proceed to the next module. Students may complete a course at any time during the semester.  If all modules of a course are not successfully completed within a semester, the student can re-enroll in the same course in the following semester beginning with their first uncompleted module.


Course may be taught as face-to-face, media-based, hybrid or online course.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

Textbook information for each course and section is available on Oakton's Schedule of Classes. Within the Schedule of Classes, textbooks can be found by clicking on an individual course section and looking for the words "View Book Information".

Textbooks can also be found at our Mathematics Textbooks page.

A scientific calculator, notebook, and earphones are required.

X.    Methods of Evaluating Student Progress

Students must complete the following work with the following minimal scores:
Homework, class work, and study plans (unlimited attempts) = 90%
Quizzes (unlimited attempts) = 85%
Module Posttest = 70%
Students receiving 85% on Module pre test may proceed to the next module.

XI.   Other Course Information

Individual instructors will establish and announce specific policies regarding attendance, due dates and make-up work, incomplete grades, etc.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.
