Vygotsky's Zone of Proximal Development ZPD is “the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult guidance, or in collaboration with more capable peers.”
Ref: Peer Instruction: A User's Manual. Eric Mazur, Prentice Hall, 1997.
"The jury didn't consist of my peers ... This jury believed citizens have a civic duty to obey the laws".
Online Peer Reviews: Outline • Pros and cons • Implementation Considerations • Student Websites • Course Website • Peer Review Process • Results
Peer Reviews – Advantages • 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 one another. • Teacher plays role of supervisor.
Example: ("do the math") 30 students Peer review of 1 assignment: 30 x 30 = 900 copies of the homeworks 5 pages/homework: 5 x 900 = 4500 pages.
Number of Reviews • Software Engineering (CSC 4508): • 34 students • Theory: • 1 Assignment: 1,122 reviews. • 15 Assignments: 16,830 reviews. • Fact: • 1 Assignment: 300 – 400 reviews. • 15 Assignments: 5,212 reviews.
Peer Reviews – Concerns • Students don’t know the subject. • Students are not skilled evaluators. • Students might send inappropriate messages. • Students will not do that much work. • Students will copy (cheat)! • Keeping track of the reviews is very difficult. • Student privacy.
Implementation Details • 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?
Course Website • Instructor sets up a course website • Web pages • Database • Scripts • Keeps track of all the activity/data
Peer Review Process • Student: • Logs onto the course website • Unique password for each student. • Sees list of URLs • List of links to the student web sites • Picks one from the list • Accesses a student web site • Finds the assignment • Reviews the assignment. • Submits an anonymous review: • score (1 – 10) • comment • Goes back to the list of URLs and picks another.
Student Website • Students use their own website. • Students must have basic web skills. • Students must have access to a web service. • Students cannot (easily) hide their identity.
Sample Peer Review ”Looks pretty good”
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
Detailed Peer Review 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.
