Abstract

Introduction: Computer-based assessments are commonly used in the physical therapy education curriculum. Feedback is an essential part of the learning process, but what effective feedback entails in the computer-based assessment environment is unclear. Educators may choose from knowledge of results, knowledge of correct results, and elaborated feedback.

Subjects: Students enrolled in a DPT program; N=49.

Methods: This study was a mixed-methods single-subject quasi-experimental design aimed to establish a cause-and-effect relationship between feedback and computer-based assessment scores. Two forms of feedback were assessed during a semester with repeated testing and alternating feedback forms. Students completed an assessment and were given one of two forms of feedback: secure exam review with note sheet (content) or strength and opportunities report (categorical). Students then repeated assessments on the same content that included a mix of repeat and related exam questions. Exam scores and question performance were analyzed with paired t-tests and logistic regression. Students were surveyed on their feedback preferences.

Results: Change scores were significantly higher on exams that received categorical feedback; however, baseline scores differed significantly between feedback types. After correcting for differences in baseline scores by calculating relative improvement from baseline, no differences were found between feedback types (p=0.7011). When the two forms of feedback were compared between the repeat and related exam questions, content feedback was more effective for repeated questions (RR = 1.53, CI95 = 1.12–2.09, p = 0.0031) but not for related questions (RR = 1.01, CI95 = 0.76–1.33, p = 0.9997). Most students (89.75%) preferred content feedback.

Discussion and Conclusion: Both forms of feedback, content and categorical, provided similar degrees of relative improvement on follow-up exams. However, content feedback seems better when a student encounters repeat questions. Students also highly preferred content feedback over categorical feedback.
