### Technical Mathematics

The mathematics department at Volunteer State Community College now offers a five semester hour course entitled, "Mathematics for Industrial Technology." In the past, the college has offered mathematics courses for general education, engineering, and business majors. The technical mathematics offering is a new direction.

In the fall of 1998 the college and Bosch Braking Systems joined with Nashville State Technical Institute to offer, for the first time, an 80 hour degree program for Bosch employees. Upon successful completion of the program these employees will receive an Associate's Degree in Industrial Technology. The timing of this program and of this Education Edge grant initiative provided an opportunity to develop an excellent technical mathematics course.

An important component of this degree program is the technical mathematics course. The authors built into this grant project the objective of developing an up-to-date mathematics course. The advantage here would be that the authors could develop this course in conjunction with people in business and industry who use mathematics every day.

After interviews and consultation with industry personnel, a new technical mathematics course emerged for the fall semester, 1998. Initially, this course will serve those in the Bosch Associate's Degree Program. However, it has the flexibility to serve the general population of students interested in a career in technology. It can also be used in other specialized programs that the college may design with other companies engaged in technological pursuits.

Appendix A provides a description of the syllabus for the new technical mathematics course.

### Assessment Techniques

Outcome statements will be assessed through in-class quizzes, tests, and problem solving. In addition, take-home assignments will be given. These assignments will involve application of course topics to various problem-solving situations. Homework problems will be assigned at each class meeting and discussed at each subsequent class meeting.

Evaluation and Attendance Policies

Evaluation: There will be 5 major tests (not including the final examination) during the semester. The major tests will be at least one hour in length. Each major test will count 100 points. There will also be several announced quizzes which will be 10-20 minutes in length. Each quiz will count 20 points.

Only the BEST FIVE quizzes will count toward the final grade in the course.

There will also be two special project assignments to be completed outside of class and turned in. These assignments will be worth 25 points each. Homework will be assigned at each class meeting.

It may be done in any format desired (i.e., loose leaf notebook, spiral notebook, folder..). It will be checked at the end of the semester for completeness and effort. Homework will count a maximum of 50 points.

There will be a final examination which will be selectively comprehensive. It will be worth 100 points. There is a total of 800 possible points to obtain.

Final grades will be assigned according to the following totals.

5 major tests = 500 points

5 best quizzes = 100 points

2 projects = 50 points

homework = 50 points

final exam = 100 points

720 - 800 points = A

640 - 719 points = B

560 - 639 points = C

480 - 559 points = D

0 - 479 points = F

Total = 800 points

### Incomplete "I" Grade

A grade of "I" is designed only for severe emergencies such as car failure on the day of the final examination, death in the family, serious illness, or some life changing event. It will not be given in the situation where a student is merely behind in his or her work.

### Inclement Weather Policy

If the College is closed due to extreme weather, this class will not meet and any events planned, i.e. test or quiz, will occur at the next class meeting. If the College is open, class will be held as usual.

Also any work due to be handed in on the date of a canceled class will be due at the next regularly scheduled meeting.

### Attendance

Prompt and regular attendance is expected. Attendance will be recorded at every meeting. The College is required by federal law to keep attendance records for purposes of financial aid. See page 52 of the current catalog (1998-99).

### Honesty Policy

Honorable and ethical behavior is expected regarding all course work. In any case where cheating is suspected, the student will be required to take an alternate test or do an alternate assignment.

In any case where there is absolute proof of cheating on any part of any course work, the student will receive an F in the course. Final decisions in these matters rest solely with the instructor.

### Make-Up Work

Due to the frequency of quizzes, a missed quiz will not be made up and will be counted as a dropped grade. The first missed major test will be replaced by the student's grade on the final exam. If a student misses a second major test, he or she will be allowed to take a make-up test of significantly greater difficulty to replace that grade. This policy is in force regardless of the reasons why a student misses a test or a quiz.

### Final Note

A mathematics class is driven by the question and answer format among all the participants, student and teacher alike. Therefore, everyone in the class is encouraged to ask a question or open discussion of a problem at any time. Some class time will be devoted to group work and group and individual presentations of problems and solutions. Everyone will be expected to be an active member of the class.

### American Disabilities Act

In compliance with the American Disabilities Act, it is the student's responsibility to contact their instructors concerning any special accommodations required for completion of course requirements.

Volunteer State Community College is an equal opportunity Affirmative Action Educational Institution. No person shall be excluded from the participation in, be denied the benefit of, or be subjected to discrimination under any program or activity of the College because of race, color, national origin, age or handicap.
