Office Hours: TRF 2:30 - 4:00

 

           

These are times when students can be certain that I will be in my office.

However, students are welcome (and encouraged) to come or call at other times.

If I am in my office and not on the phone or with another student, I will make time for you.  At minimum, we will arrange a time to meet that will accommodate both of our schedules.

 

Objectives:     1. Introduce the fundamentals of the chemistry of engineered materials

2. Expand the understanding of the classes of materials, with an emphasis on                                  polymers and composites.

3. Develop the capacity to make informed, scientific decisions involving materials

    selection and processing

 

Responsibilities: To succeed in this class, you should read the relevant material before coming                                     to class, make a reasonable effort to do the assigned homework, hand in what you

accomplish, and ask questions on points that you do not understand.  I will lecture on points in the book and on supplemental topics, attempt to answer all serious questions, make myself available to anyone needing extra help, administer fair but demanding exams, and grade and return assignments in a reasonable time.  All exams will be graded by the next class period.

 

Grading:                                             2 1-hour exams            44.44%

Oral Presentation          22.22%

Final Exam                   33.33%

 

 

Policies:          1. Homework will be collected and checked.  Team homework assignment will be collected and evaluated by a three-tier system (+, -, o).  The plus represents a solid effort, the minus a partial or sporadic effort, and a o indicates little or no effort.  No student can receive an “A” in the course whose team has more than one o or more than 2 assignments that have received anything other than +.

 

2. Regular attendance is expected.  You are responsible for all assignments and                                         material covered in class whether you are there or not.

 

3. Collaboration on homework assignments is encouraged; however, ALL                        EXAMS MUST BE DONE INDEPENDENTLY.  Academic misconduct will result in a failing grade for the class.


4. Make-up exams will not be given without documentation of illness or                             emergency unless arrangements are made in advance.  A single COMPREHENSIVE makeup exam will be given in early December to any student who misses any exam.

 

5. Class begins promptly at 11:00 A.M. (9:00 A.M. on Fridays) and will end at promptly 12:15 (10:15).  Should the class run later than 12:20 three times during the semester (except for answering questions), I will bring doughnuts for the entire class during the next lecture.

 

6.  If you feel that your exam has been graded improperly, resubmit the exam with a detailed WRITTEN explanation of what you perceive the error to be.  I will REGRADE the problem in question (Note – Your score can move up or down).  All test grade appeals must be received by the next class meeting after going over the test.  The only exception to this policy will occur if I miss-add your total score.
