Extra Help

Extra help is always available for any concern, small or large. All you have to do is arrange a time, before or after school or during periods 1, 6 or 8.

 

Homework / Graded Assignments

All homework is due on time. Make it meaningful and do it well.  Homework will be checked off and counted as complete, or it will be collected and graded. If you are absent (and not truant) from class, any missed assignments, tests, and quizzes must be made up within 5 days of the day you return.

 

Grading: will be based on percentages.

1. Lab activities/assignments 80%
2. Test and Quizzes 10%
3. Safe and proper care of tools, equipment, and lab space 10%

 

Grade book (POWER SCHOOL) policy for updating student grades

In order to provide students with timely and effective feedback every effort will be made to grade and update student work as quickly as possible. Tests and homework will be entered within 3 days. Other grades are detailed below.

The Technology Education classes engage students in long term projects and activities.  Some of these projects can take up to a full semester.  Large projects will be broken into three or more separate grades. These component grades will be given approximately every two weeks. This will provide students with ongoing feedback throughout the assignment.  In addition to homework, test and assignment grades, throughout most of the year, a weekly lab grade will be provided. The lab grade will reflect student’s laboratory safety, laboratory project management and laboratory professionalism.  The score will be based on a rubric.

Attendance-due to the laboratory nature of the course students must make up missed lab days or lose 3 points from their marking period grade for each day absent.  Student may make up labs before and after school or during a study hall.  They must schedule these lab make ups in advance with the instructor.  Student will be allowed 2 missed classes per marking period without affecting their grade. With the third missed class students must make up missed lab days.

 

Working in the lab:  Diagnosing and repairing vehicles requires the highest level of care for both the vehicle and the occupants who will be operating it.  Double and triple checking your work is a necessity along with having the instructor check all repairs before leaving the lab.  Great responsibility goes along with auto repair.
