2. Homework Grading Bottleneck

3. Students/Graders Teacher/Supervisor But: 1.N x N-1 copies! 2.Students can’t grade accurately. 3.Too much work for the students. 4.Cheating?

4. Peer Reviews – Why? Students learn from each other. Students get lots of feedback. Students develop skills as evaluators. Students learn to appreciate evaluation criteria. Students see how they compare to peers. Students see class from the teacher’s perspective. Students get to know each other. Teacher plays role of supervisor (A much better use of the teacher’s skills/knowledge).

5. Peer Reviews – Why Not? Students don’t know the subject. Students are not skilled evaluators. Students can not, or will not, do that much work. Students will copy (cheat)! Keeping track of the reviews is very difficult. Student privacy.

6. Peer Reviews – How? Student Web Pages: –Students post homework solutions on their own web page. Course Web Site: –Set up course web site to manage all the peer review activity. Keep track of: Links to student web pages, Peer Reviews: –Scores, –Comments. Anonymous reviews.

11. Entering a Peer Review

12. Peer Reviews Received

13. ” Looks pretty good” perfunctory \pur-FUNGK-tuh-ree\ -- adjective : Done merely to carry out a duty; performed mechanically; done in a careless and superficial manner; characterized by indifference Sample Peer Review

14. You should have requirements that detail the concepts in section 4.2. Although you had some very good points (i.e. the database should look up student's degree requirements; view should list courses, etc...) almost all your requirements can be more detailed. Go through section 4.2 (each of the sections) and think of what the program would need to do to effective run. Some good examples of what requirements are necessary are on others' websites, however I'll give some to you now: 1.Is there a timeline requirement? 2.Is there a requirement on how much(or how little) this will cost? 3.Is there security requirements? 4.Is there user view requirements? These(and many other questions) are what you should answer in your requirements definition document. Good luck on Assignment #3. Sample Peer Review
