V. Evaluation:
A. Testing Procedures:
Four one-hour (50-minute) written tests will be given during the semester.  A written, one-hour comprehensive final examination will be given after the end of regular classes.  Each test has equal weight in calculating the lecture course grade.  The final examination has the weight of a single test in calculating the lecture course grade. 
B. Laboratory Expectations:
The laboratory course grade is assigned separately from the lecture course grade and is based on report writing, keeping of a laboratory notebook, and experimental competence. Each laboratory session has equal weight in determining the laboratory course grade.  The materials of construction report has the weight of two laboratory sessions, for lab sessions 1 and 2.  The report on the metallography, hardness, and microstructure of steel (lab session 13) has the weight of two lab sessions. 

The schedule of laboratory assignments for each week of the semester is: 
1 Laboratory orientation and safety, and library research
2 Library research and report on materials of construction
3 Tensile strength testing of fibers, data collection
4 Tensile strength testing of fibers, computations and statistics
5 Freezing-melting points of ice-salt, data collection
6 Freezing-melting points of ice-sale, phase diagram construction
7 Corrosion of plastics by solvents, sampler preparation
8 Corrosion of plastics by solvents, data collection and statistics

12 Etching and photography of metallogrpahic specimen
13 Library research and report on microstructure of steels
14 Corrosion of metals, sample preparation
15 Corrosion of metals, data collection
 
C. Field Work:
The two required reports which involve library research are treated as field work. A research report covering a new material of construction will be assigned. Each student will make a short oral presentation of his or her report. The written and oral reports will be graded and will together have the weight of a one hour exam.

VI. Policies:
A. Attendance Policy:
Pellissippi State Technical Community College expects students to attend all scheduled instructional activities.  As a minimum, students in all courses must be present for at least 75 percent of their scheduled class and laboratory meetings in order to receive credit for the course (Pellissippi State Catalog).  Individual departments/programs/disciplines, with the approval of the vice president of Academic and Student Affairs, may have requirements that are more stringent. 
Chemical/Environmental Engineering Technology Program: 
Regular attendance in this course is required.  Students who miss the equivalent of 10% of either classroom hours or laboratory may, at the discretion of the instructor, have their course grade dropped by one letter.  Students who arrive late for a class after the roll as been called have the responsibility of seeing the instructor after class the change their status from A (absent) to T (tardy).
B. Academic Dishonesty:
In keeping with college-wide policies, the student is expected to adhere to the general rules and regulations relevant to academic and classroom misconduct as outline in the catalog.
