Changes in rapid-guessing behavior over a series of assessments
A series of 8 tests was administered to university students over 4 weeks for program assessment purposes. The stakes of these tests were low for students; they received course points based on test completion, not test performance. Tests were administered in a counterbalanced order across 2 administrations. Response time effort, a measure of the proportion of items on which solution behavior rather than rapid-guessing behavior was used, was higher when a test was administered in the 1st week. Test scores were also higher. Differences between Week 1 and Week 4 test scores decreased when the test was scored with an effort-moderated model that took into account whether the student used solution or rapid-guessing behavior. Differences further decreased when students who used rapid-guessing on 5 or more of the 30 items were filtered from the data set.
