7. Evaluation Notes:

 

(a) Homework: Homework is assigned on a biweekly basis and is meant to review/emphasize important key learning concepts and calculations.

 

(b) Quizzes: Short in-class or take-home quizzes will be assigned 3 times per semester to consolidate knowledge learned in class.

 

(c) Exams: 3 x in-class exams: mid-term exam 1, mid-term exam 2, and final exam. Final exam is not comprehensive, but covers topics the instructor deems important.

 

(d) **Laboratory: (Administered by Lab Instructor, Dr. Sinha)

- Students work in teams during lab sessions, but each person is responsible for his/her own report.

- Electronic copies of lab reports & assignments are to be turned in via iLearn on designated dates.

- Attendance and on-time assignments/reports each contributes 50% of lab grade.

 

(e) **Project: (Administered by Lab Instructors, Dr. Sinha)

- Teams of 3 persons will work on a “materials-related project”.

- A final oral presentation and a final written report are required.

- Electronic copies of presentation file (.ppt) and final report are to be submitted via iLearn.

- Grade is assigned on a team basis, with consideration given to individual performance.

 

(f) Special Note: Late work is not accepted. Incomplete grade will not be assigned in this class. Cheating and/or plagiarism result in a letter grade F with immediate effect.
