VIII. Course Practices Required

Course may be taught as face-to-face.

Reading: The student will be responsible to read hand outs and required assignments from the textbook and instructional materials before scheduled class discussion.

Writing: The student should maintain a comprehensive notebook of lecture and lab topics for reference during class and discussions.

Homework: The student will be responsible for the completion and submitting of homework assignments in a timely manner. Homework will be accepted only on the day assigned or by making arrangements with the instructor for students who are absent on that class day.

IX.   Instructional Materials

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

At times the instructor will supply handouts and additional training materials to the students. Manufacture specifications, shop manual references and procedures will be looked up by the students with the use of computer based Mitchell OnDemand, and the use of the internet. The students will supply his/her course textbook, paper, and writing implements.

X.    Methods of Evaluating Student Progress

Students will be evaluated on class participation, tests/quizzes, homework, lab participation (hands on work), lab sheets, and attendance.

FINAL GRADE DETERMINATION:

Homework* 10%
Quizzes 10%
Attendance** 10%
Mid-term Test 20%
Final Test 20%
Lab 30%
100%

* Homework: Late homework will count only 50%.

** Attendance: Student attendance is critical for satisfactory completion of course work. Each unexcused absence will reduce your grade by 2% with a maximum of 5 unexcused absences. Three unexcused tardiness equals one day missed. If needed in certain situations, the student will need to bring in proof of absence.

90 – 100 A
80 – 89 B
70 – 79 C
60 – 69 D
0 – 59 F

Missed lab assignments maybe made up if there is time allotted and with some form of proof why the student was absent.
