Evaluation of a Computer-Based Feedback System.
Kaufman, David; Conry, Robert
This paper evaluates the effects of two distinct modes of feedback to students. These two modes comprise: (1) predicted final course grade, and (2) current standing in class. The experiment was conducted with a final year class of 56 students attending a required half-year course in Educational Measurement. The class was divided into four treatment groups (2 x 2 factorial design) and different feedback of results was mailed to each group for the four objective class tests written before final exam. Two FORTRAN computer programs were used to determine class standing, current grades and predicted final course grades. The predicted final exam and course grades were obtained by applying a linear least-squares line of best fit to the test data and extrapolating to future tests and to the final exam. The class standing was obtained by using a FORTRAN sorting program. Analysis of variance was performed on the final exam grades, and no significant differences were found in final exam performance or in satisfaction with feedback received (Chi-squared test), although results slightly favored the feedback groups. The computer program was found to adequately predict the final exam grades, i.e., the linear regression was significant. (Author/DB)
