- Summary:
-
The relationship between the multiple-choice and free-response sections of the Computer Science and Chemistry tests of the College Board's Advanced Placement program was studied. Confirmatory factor analysis showed that the free-response sections measure the same underlying proficiency as the multiple-choice sections for the most part. However, there was a significant, if relatively small, amount of local dependence among the free-response items that produced a small degree of multidimensionality for each test. Data from the Computer Science test came from 2 random samples of 1,000 students each from a previous study of the 1988 test administration. Data from the Chemistry test came from a sample of 2,000 students choosing one free-response problem and 2,000 choosing another. (Contains 4 tables, 1 figure, and 17 references.) (Author/SLD)
