Expected Student Behavior

 

\
Notebook & Class Equipment
\
Students are required to take notes during lectures, and to turn in a notebook for grading prior to the final exam. Articles, accumulated information, and useful reference material that pertain to relative course topics will be counted toward the notebook grade. Notebook should contain handouts, formula sheets, test, assignments, and task list. All items will be graded from the notebook. Student shall furnish a scientific calculator and personal protective equipment to include safety glasses. Student shall have their own personal hand tools similar to those on the department service tool list. Student shall furnish necessary computer media for information transfer. Student shall furnish required text and Handyman Pocket Handbook.
\
 
\
Shop Policy
\
Read safety handouts provided, use common sense, maintain safe shop practices, keep your Lab clean, and orderly. Keep all safety shields/guards, and equipment in place at all times. Notify your Instructor of faulty wiring/equipment, worn or damaged tools, or missing parts. No horseplay is allowed whatsoever. Academic disciplinary measures will be promptly administered to offending person(s). Please help the Instructor to maintain order so that he can be free to use your time for more effective teaching, and less time housekeeping. We all can enjoy the benefits of an effective and conducive learning environment. Remember to use your safety glasses when entering the shop area. Always perform proper Lock-out / Tag-out.
\
 
\
Tools, Equipment, and Clothing
\
Students shall wear appropriate clothing to perform any work task assigned. Tools and equipment specified for this class and any recommended preliminary class in the Nondestructive Testing and Evaluation curriculum are to be furnished by the student. Failure to dress for work or bring needed equipment may count as an absence. All tools should be properly used and cared for, thus allowing for longevity and safety of both the user and the tool.
\
 
\
Stealing, vandalism, or pilferage will be dealt with severely!! No drugs, tobacco, drinks, or food allowed!

Grading Criteria

 

\
 \
Course Evaluations:
\
Students should complete all performance tasks on time at REQUIRED MASTERY LEVEL. Tasks, projects, and various assignments will be scored based on time; accuracy; neatness; completeness; procedure; skill; detail; motivation and attitude; safety practices; clean up; care of manuals, logbooks, and references; and other grading criteria. No task shall be rated until assignment is complete. Complete shall include condition and cleanliness of equipment; clean up of work areas; tool condition and return; all projects, supplies and materials being stored properly. Failure to bring books, notes, notebook, and equipment for a given class may result in a failing grade for that class period. Unless the instructor specifies otherwise, all homework is due at the beginnig of the next class.
\
 
\
\
Final (Overall) Grade Policy:
\
The final overall grade will be computed by adding the points earned as follows:

\
800 -   899 pts = B
\
700 -   799 pts = C
\
600 -   699 pts = D
\
    0 -   599 pts = F

 

\
Students are responsible for getting notes from other students when absent. Lab activities will continue on schedule. Individuals will not receive credit for making up activities and there will not be special lab sessions. Some work can be caught up during regular lab times. Missing lab activities may prevent individuals from performing advanced lab exercises for safety and expense reasons.
\
 

Attendance

 

\
Attendance in class and lab participation is regarded as a requirement and an obligation for learning. Student is responsible for clocking-in and clocking-out with the provided system, just as they would at work. Failure to clock-in or clock-out will result in loss of points for that session. Showing up late or leaving before instructor dismisses class will result in points reduction for that session. There are generally 16 sessions per semester. Instructor will only grade on 14 sessions. (That means two excused or unexcused absences without penalty; however, mid-term and final exam dates are absolutely attendance mandatory.) If a student must miss because of some other obligation, then the student needs to call the instructor's office at 335-4263 or 335-4390 and leave a message before class starts. Partial credit may be applied to the attendance for that session. Lab and class room participation is rolled into the attendance grade (10 pts./session). Showing up without texts, supplies, equipment and proper dress will result in grade reduction.
