This is your opportunity to dig in deep into a topic you are very interested in. You will then teach your peers what you learned about your selected topic. Your job as the presenter is to convey the key points about the topic, as though you were writing the Cliff’s Notes for the topic. Guidelines: • 15 minutes at beginning of lecture. • Use the textbook; can use other references to help yourself understand, but try to teach only the concepts covered in the relevant sections of the textbook (see previous page of syllabus for list of relevant sections for your topic). • Any format goes! Use words, tables, figures, demos, handouts, Power Point, write on the board, etc. – however you can most clearly get your message across. • Ask questions of your peers! Content of presentation: • Provide a brief and basic description of the material system to ensure your peers are familiarized with the type of material you’re studying (e.g. give examples of that material system, crystal structure, fabrication and processing, etc.) • Describe the general elastic, plastic, or fracture behavior. • Describe the driving mechanism(s), if known, of this behavior. • What factors most significantly influence this behavior? How so? • What are the most important parameters used to describe this behavior (e.g. modulus of elasticity, fracture toughness, etc.)? What are ballpark values for this parameter, and how do they compare to that of other material systems? • Present key equations governing the behavior, as needed. • Place your topic in the context of the course. • Describe the societal impact of your topic. Presentation grading rubric: Content is accurate and technically-sound Key concepts are identified and clearly stated Uses course concepts to help explain the topic Presentation skills (articulate, friendly, eye contact) Clearly organized and concise presentation Relates the topic to society Media used is appropriate and effective TOTAL 40 points 20 10 10 10 5 5 100 points Note: On exams, I expect everyone to be able to compare the elastic, plastic, or fracture behavior across different material systems. But you will only be expected to know fundamental or key concepts – you will not need to have as much in-depth understanding SYLLABUS – MSE 512, Spring 2015 of each topic as the presenter. I will also reinforce key points on each topic following the presentations.
