| Popis: | 92 Spatial sense forms a part of the visual thinking used in everyday life. Research on spatial aptitude has determined the components that underlie spatial ability. Advances in cognitive psychology deepen our understanding on how students gain and use knowledge. Advances in technology make it possible to capture more realistic performances in assessment settings by including multi-media dynamic presentation. The purposes of this study were developing a computerized authentic spatial sense test (CASST) and proposing a five-component-model to predict the tasks’ difficulty parameters. The components included are degree of transformation, folding /visualization, distance perception, geometric concept, and location/ position. Linear logistic test model was adopted for model usability discussion. A total of 867 4th, 5th, and 6th graders were sampled as the norm for CASST. The average difficulty (p value) is .51 for the norm. The correlation coefficients between CASST and concurrent related variables such as working memory, mathematics ability, school math or science score are around .5 to .6. The proposed 5 components accounted 73% variances of difficulty parameters of CASST. The CASST can also be considered as a supplemental instrument for screening gifted students. Its incremental validity is higher than the Numerical and Spatial Working Memory Test. Three difficulty levels were adopted preliminarily to describe students’ performances. Around 18% 6th graders performed below the basic level. They will need substantial support for visualization and transformation tasks. Generally speaking, more students (65%) preferred CASST better than conventional test. Around 85% students thought the dynamic presentation format is helpful for their spatial thinking. Students with more active learning motivation and less test anxiety performed better on CASST. The five components investigated in this study might serve as the basis for further compensatory intervention of spatial sense. |
