Free-Response and Multiple-Choice Items: Measures of the Same Ability?
Bennett, Randy Elliot; And Others
This study examined the relationship of multiple-choice and free-response items contained on the College Board's Advanced Placement Computer Science (APCS) examination. Subjects were two samples of 1,000 randomly drawn from the population of 7,372 high school students taking the 1988 examination of the APCS "AB" form. Most were high school seniors, most were male, and most were white. Confirmatory factor analysis was used to test the fit of a two-factor model where each item format marked its own factor. Results showed a single-factor solution to fit the data best in each of the two random-half samples. This finding might be accounted for by several mechanisms, including overlap in the specific processes assessed by the multiple-choice and free-response items and the limited opportunity for skill differentiation afforded by the year-long APCS course. Appendix A contains an example of the scoring rubric, and Appendix B presents a sample correlation matrix. (Contains 2 figures, 6 tables, and 21 references.) (Author/SLD)
