Concept Map Overview
Study
Questions
What instructional practices improve students’ electronic portfolio entries?
Does metadata (tags and categories) predict performance?

Writing
“writing ability is a source of construct-irrelevant variance” (Mislevy et la., 2004)

Evidence-Based Learning
• Artifacts
• Program Standards
Method
• Context and Participants
– Convenience Sample
– 11 Undergraduates
• Mostly females
Method
• Repeated measures
– Three portfolio entries
First Entry Second Entry Third Entry
8 months before
intervention
1 week before
intervention During
intervention
Method
• Measure: – Writing Quality Rubric
• Adapted from AACU VALUE rubrics • .82 inter-rater reliability

Method
Method
Writing Quality Score
Number of Tag Cloud Terms
Results
• Statistically significant improvement
M = 5.82 M = 2.36 M = 0.55
t(10) = 4.99, p < .001, d = 3.16, 95% CI = 1.91 to 5.00

Results
• Statistically significant correlation between
– Tag cloud terms –writing quality
– Total portfolio entries – writing quality
Discussion
• Intervention improved writing quality on third entry
• Use of metadata to predict general writing quality
1 Intervention
• Explicit directions on content and format
– Prompt
– Instructions
2 Intervention
• Communication of Assessment Criteria
– Rubric
3 Intervention
• Evaluating evidence
– Questions
4 Intervention
• Instructor and peer feedback
– Strengths and weaknesses
• Submitted to instructor
• Read aloud to peer
5 Intervention
• Revising
– Initial submission
• Instructor feedback
• Peer feedback
– Final submission
