| Abstract | This report summarizes the results of research designed to study the psychometric and technological feasibility of adaptive testing to assess spatial ability. Data was collected from high school students on two types of spatial items: three-dimensional cubes and hidden figure items. The analysis of the three-dimensional cubes focused on the fit of the simplest possible item response model capable of modeling response time; the analysis of the hidden figure item focused on the feasibility of generating items from an algorithm in such a way that the psychometric characteristics of the generated items were predictable. The results for the three-dimensional cube items suggested that angular disparity can be used effectively to control the difficulty of true items, but this was not the case for false items. That is, true and false items appear to measure different aspects of performance, and as a result, a multidimensional item response model may be necessary to fully account for performance. The analysis of the hidden figure item 3 showed that an item generation algorithm can be formulated to produce items of similar psychometric characteristics. The practical and theoretical implication of the results are discussed. (Author/JAZ) |
