(1990). The relationship of expert-system scored constrained free-response items to multiple-choice and open-ended items. Applied Psychological Measurement, 14, 151-162. doi:10.1177/014662169001400204doi:10.1177/014662169001400204https://hdl.handle.net/11299/113256This study examined the relationship of an expert-system scored constrained free-response item (requiring the student to debug a faulty computer program) to two other item types: (1) multiple-choice and (2) free-response (requiring production of a program). Confirmatory factor analysis was used to test the fit of a three-factor model to these data and to compare the fit of the model to three alternatives. These models were fit using two random-half samples, one given a faulty program containing one bug and the other a program with three bugs. A single-factor model best fit the data for the sample taking the one-bug constrained free response and a two-factor model fit the data somewhat better for the second sample. In addition, the factor intercorrelations showed this item type to be highly related to both the free-response and multiple-choice measures.
