Intelligent Tutoring System (ITS 2010) CSPR Conference
Morrison, J. A Research Framework to Examine the Impact of Online Peer Review on Learning Outcomes in Computer Science Courses Background: 10,000 students, mostly undergraduate students. Peer Review System - did not have until now as more research models are available. Most systems looked at the acceptance of the system as the measure for evaluation. Previous experiments done - Correlations between instruction and peer assessments - student attitudes towards peer review - impacts on higher learning processes - descriptions of online peer review systems - description of online peer review configurations and processes. Findings on Improving Learning Outcomes - Addressed in general education literature but limited in CS Education literature. Exceptions - Liu et. al. (2001) : improved motivation - Turner et. al (2010) : improved understanding of specific subjects. Existing foundations: - Social Constructivisim - Learning takes place due to interactions within a group Proposed Research Framework: Variables
  • Reviewer/Reviewee (Age, Gender, Grade Level, Personality Type, Ability)
  • Assignment: Domain, Complexity, Creativity, Configuration , Time Frame
  • Review process: Configuration, Number of review Cycles, Reward, Time Frame, Privacy, Assessment Scoring Criteria, Assessment criteria source, Instructor Role.
Outcomes Student(Formative) - Still in writing critique - Domain knowledge about a specific task or process - Knowledge beyond the current task - Meta cognition - Motivation - Confidence - Sense of Community Instructor(Summative) - Assessment Convergence - Revelation of additional errors/issues Ideas for Future OPR Studies - Reviewer/reviewee demographics Gender - Confidence, motivation personality types - improvement in writing reviews - Existing Domain Knowledge manipulate all combinations (High-high, High - low, low - high, low - low) - Assignment Domain planning/design Review Configuration in programming assignments - Self, peer and instructor summative convergence Instructor Role - Facilitator role - perceptions of instructor Future Directions/Discussions Refine the model - Widen the literature scope - Perform empirical studies Discussion
