Online Peer Reviews: Outline

• Pros and cons

• Implementation Considerations

• Students Websites

• Course Website

• Peer Review Process

• Results

Peer Reviews – Pro

• 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 their peers.• Students see the class from teacher’s perspective.• Students get to know each other.• Teacher plays role of supervisor

(A much better use of the teacher’s skills/knowledge).

Peer Reviews – Con

• 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.

Considerations

• What type of assignment?• How many reviews does each student do?• How many reviews does each student get?• Who reviews whom?• Does the reviewer have to be “qualified”?• Will students grade fairly and accurately?• Anonymous reviews?• Grades based on peer reviews?• Grade the peer reviews?• Opportunity to revise based on reviews?• Peer review of the peer reviews?

Peer Review System

Student Website

• Students use their own website.

• Students must have basic web page skills.

• Student must have access to a web server.

• Student cannot (easily) hide their identity.

Peer Review Process

• Student logs on the course website

• Sees list of links to other students pages

• Accesses student assignments

• Enters “score + comment” for each review

Grading Criteria (Rubric)

 ”Looks pretty good”

Sample Peer Review

Perfunctory Reviews

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

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.
