(CAI) correlate with exam performance?

Objectives: Understanding how student use of CAI affects
learning is essential to making evidence-based decisions about CAI
integration. In this pilot study we evaluated the correlation between
time spent using CLIPP (Computer-assisted Learning In Pediatrics
Project) cases with scores on a final exam based on the content
of the CLIPP cases.
Methods: CLIPP cases were integrated into the clerkship
at 3 institutions, each of which used the CLIPP final exam. The
exam included 4 questions from each of the 20 CLIPP cases studied.
Computer log data was queried to find the time spent on each case.
Pearson's product-moment correlation test with Bonferroni adjustment
was used to assess the correlation between time spent on each case
and the percent of correct answers on that case, as well as comparing
total time spent on all cases to the overall exam score.
Results: Data were collected on sixty-one medical students.
Correlations between the time spent and percent correct answers
for each case showed no practical or statistical significance ®
range -0.071 to 0.32). The same conclusion was obtained for the
correlation between time spent and percent correct answers for the
overall exam scores (r=0.17, p=0.19). These correlations were not
adjusted for other potential confounders.
Conclusions: This pilot study suggests that students
who spend longer times working on CLIPP CAI cases do not score significantly
higher on an exam that tests the content of the cases. Variations
in learning style, clinical exposure and other teaching may affect
these results. This can be tested in the larger dataset that is
accruing.
