A Multidimensional Scaling Study of College Students' Perception of Test Item Formats |
| |
| Abstract: | College students use information about upcoming tests, including the item formats to be used, to guide their study strategies and allocation of effort, but little is known about how students perceive item formats. In this study, college students rated the dissimilarity of pairs of common item formats (true/false, multiple choice, essay, fill-in-the-blank, matching, short answer, analogy, and arrangement). A multidimensional scaling model with individual differences (INDSCAL) was fit to the data of 11 1 students and suggested that they were using two dimensions to distinguish among these formats. One dimension separated supply from selection items, and the formats' positions on the dimension were related to ratings of difficulty, review time allocated, objectivity, and recognition (as opposed to recall) required. The second dimension ordered item formats from those with few options from which to choose (e.g., true/false) or brief responses (e.g., fill-in-the-blank), to those with many options from which to choose (e.g., matching) or long responses (e.g., essay). These student perceptions are likely to mediate the impact of classroom evaluation on student study strategies and allocation of effort. |
