Hierarchical Analysis of the Randomized Multiple Choice Format.
Harke, Douglas J.
This paper describes two quantitative methods of hierarchical analysis used to measure the similarity of sequences or hierarchies of steps on two test formats, the Randomized Multiple Choice (RMS) format, and the free-response problem test format. The investigator first used the Consistency Ratio method to quantitatively assess the transfer relationships for each set of dependency relationships in the hierarchy of RMS items. Consistency ratios for six test problems were calculated. The results indicated that the responses of the subjects as a whole validated most of the dependency relationships within the hierarchies and that in most segments of the hierarchies the students probably were required to use the same problem solving skills and procedures on the RMC and free-response problems. The pattern analysis technique was also used to analyze the responses for the complete hierarchy on a subject by subject basis. Indices of agreement for the six RMC problems were calculated. They revealed the amount of similarity between sequences of physical and mathematical concepts used in solving a problem in the RMC and free-response formats. Bibliography. (LC)
