5.         ATTENDANCE: Attendance is critical in order to successfully complete this course.

5.1              Much of the material is covered by lecture and demonstration, which makes it difficult to make up.

5.2              The drop and attendance policy described in the Merced College 2007-2008 catalog (page 31) will be used as a basis for this class.

5.3              Obviously, students who do not attend class will not benefit from lectures and demonstrations and will not complete assignments on time, which will affect the final grade.

5.31          After three absences, students’ grade may be lowered by a half a letter grade for each additional class missed.

5.311   Student may be dropped from the class after 3 absences, if in the opinion of the instructor; the student cannot successfully complete the class or will present a safety hazard to him or others because of instruction he has missed.

5.32          It is the student's responsibility to verify that the instructor has accurate attendance information when the student is tardy.

 

6.         LATE WORK: Missed test and late work will only be accepted late on a case-by-case basis, generally requiring advance notice.

 

7.         GRADING SYSTEM: Grading will be on a point system. Points are earned from various class and lab activities.  Points will be awarded both subjectively and objectively. At the end of the semester a “modified” curve will be used to determine the letter grade. Approximately 1/3 of your grade will be based on class assignments, 1/3 from lab exercises, and 1/3 from lab and written finals.

            7.1       Class Work: Written assignments, tests, quizzes, presentations, and reports.

                        7.11     To ensure you receive credit, PRINT the following on all work turned in:

                                                NAME, first and last

                                                CLASS number and time

                                                TITLE of work (i.e. chapter questions)

                                                DATE

            7.2       Lab Work: Required jobs, other lab work, clean up, and practical final.

 

8.         SAFETY: All students must complete S/P2 Training for Mechanical Repair Safety and Mechanical Repair Pollution Prevention within the first two weeks of instruction. To begin, go to www.sp2.org and log in to S/P2. The school User Name is: “67274” and school password is: “short”. Your private password will be your first and last initials and the last four digits of your student ID number. When you have completed the instruction and passed the tests, print the certificates and turn a copy for them into the tool room.

8.1       Safety glasses MUST BE WORN AT ALL TIMES in the lab and any time the student is performing hazardous tasks in the classroom. (i.e. soldering)

            8.2       Exhaust systems must be used whenever an engine is running in the shop.

8.3       Become familiar with the location and operation of safety equipment in the lab.

            8.4       Only students with a valid Drivers License may drive vehicles on campus.

            9.2       Philosophy:

9.21     In order to become proficient at diagnosing and repairing electrical problems, one must understand the basic operation of the system being worked on---must know how it works.

9.22     The most important tool in repair is knowledge.  Knowledge is the understanding of the system, the ability to use and comprehend reference material and the ability to use test equipment and interpret the information obtained.

9.23     The program belongs to you, and its success rests largely with you, the student.  PARTICIPATE!

            9.3       Expectations:

                        9.31     Reading assignments will be completed on schedule.

                        9.32     Students will enter into discussions enthusiastically.

                        9.33     Students will confine discussions to the problem at hand.

9.34     Only one person should speak at a time, with others listening attentively to the discussion.

                        9.35     Students will be prompt and regular in attendance.

                        9.36     Students will take pride in the work they perform for this class.

9.37     School property and equipment will be treated as if it belonged to the individual using it--with care and respect.

                        9.38     Students are enrolled in this class because they have a desire to learn.

 

10.       CLASS REQUIREMENTS:

            10.1     Unit quizzes, mid-term, and final exam.

                        10.11   Note taking is encouraged.

10.2     To gain the most from the lectures and lab exercises, the assigned reading should be completed on schedule.  To encourage this, unannounced quizzes may be given on reading material.

10.3     One, one page technical article reviews or web site reviews.  Articles should be current

 and related to course content. (Do not use an advertisement as a technical article.)

            10.31   Paper is generally, at least 1 page typed double spaced.

10.32   Paper should have an introductory paragraph explaining why you chose or were

interested in the subject.  One or two paragraphs describing the content of the

article or website, and a concluding paragraph explaining what you thought

about the article and why.

10.33    Review must include web site address, or periodical name, date, article

             title, author and page numbers.
