EGR 221 - Materials Science

Fall 2015

Syllabus

Notebook: You will be required to maintain a course notebook to keep all class related information in: syllabus, list of assignments and due dates, returned course work (assignments and exams) and course notes. You may use any form of "notebook" (spiral, 3-ring, etc.) and may have a separate notebook for taking notes. But all course related work must be well organized.

Textbook: Askeland and Wright, The Science and Engineering of Materials, Cengage Learning, Boston, Massachusetts, 7 th ed., 2016. Note regarding textbook:  The textbook will be useful in future classes, espcially EGR270. I HIGHLY recommend you keep this text at least through next year. To remember this, I'd recommend you put a post-it note inside the front cover of the book right now to remind yourself!

PURPOSE OF HOMEWORK: homework provides students an opportunity to actively learn the specific subject matter. It should be approached as such, and not as merly a bothersome task to be completed. To avoid "busy work" I assign the minimum amount of problems thatI believe necessary for most students. If you do not feel you fully understand the subject matter - which is not unusual, I HIGHLY encourage you to go "above and beyond" and work on problems from the textbook. Almost all students need to do so from time to time in order to get full advantage of their education.
