purpose
Purpose
  • Gather baselineanswer-changing patterns on a computer-based achievement test
  • Add to the knowledge base in this area
methods
Methods
  • Third grade summative test in mathematics, one state testing program
  • One, 2012 form
  • 70 items, no time-limit
  • Students can review and change items as desired
methods1
Methods
  • Assessment System Logs
    • Linear path through the test
    • Time spent viewing an item
    • Number of reviews
    • Number and pattern of changes
  • Unique benefit of CBT

discussion
Discussion
  • Limitations
    • One form, one subject, one grade
    • Nested data
    • Distributions are not normal
discussion1
Discussion
  • Answer patterns and elapsed time add to answer-changing interpretations
future
Future
  • Further exploration of wrong-to-right changes by elapsed screen time and position of change
  • Other sources of variance
    • Item-factors (difficulty, position)
    • Student-factors (demographics)
    • Nesting (buildings, districts, classrooms)
