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:

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.

Methods of Instruction

Course material will be delivered online. Interaction with instructor will be via e-mail  and, if student desires, face to face during office hours.

Course Practices

Students must contact instructor by e-mail once a week or show active pursuit of the class via online activity each week or  risk being dropped from the course.

 

Students are responsible for online homework exercises and online quizzes.

 

There will be three on-campus exams. Although the course is completely online, these on-campus exams will be paper and pencil tests, to allow students to receive partial credit. The material on exams reflects the material from the online homework and online quizzes. Students may bring one page of notes (both sides) to each exam. A corrected copy of each completed exam and original notes will be returned to student after exam is graded.

 

For remote students, testing arrangements can be made at a convenient alternate location.

Methods of Evaluation

Chapter Online quizzes                        10% of grade
Online Tutorial Exercises                    10% of grade
Two on-campus exams              each 25% of grade
Final on-campus                                30% of grade

Grading

90-100	A
80-89	B
70-79	C
60-69	D
Below 60	F
