| Summary: | 碩士 === 國立臺南大學 === 測驗統計研究所 === 94 === The purpose of this study is to develop a Computerized Science Problem Solving Test
(CSPST). Twice pretests of revising the scoring rubrics in the study aimed to build up the automated test scoring. The study object focused on elementary students at 5th and 6 th grade. 602 students among them were the norm samples in CSPST. The major component included in CSPST was problem solving with technology, it comprised science inquiry as well as problem solving with multimedia, Science inquiry contained exploration and integration. CSPST was a performance test of model, containing search module and simulation module. Problem solving with multimedia was more difficult than exploration for norm students in this study. The correlation coefficients between CSPST and concurrent related variables (test of science inquiry ability, science and life technology and math) are around .4 to .5. CSPST was described as two difficulty levels with the preliminarily observatory index of average point of .5. Two difficulty levels were developed to describe students’ performances. Each level contained four or five observatory pointers, and separated norm students into three levels of ability. The result showed that the performance of 6th graders was obviously better than that of 5th graders. There were significant differences in grades on CSPST. Variable of grade on problem solving with technology was 1.4﹪variances accounted. The differences between the gifted students and norm class students were relatively large (12.7﹪variances accounted) on CSPST. CSPST can discriminate the gifted students with the correction of 73﹪. It suggested CSPST can be considered as a potential instrument for screening gifted students. About 80﹪norm students held the positive effects on CSPST, and there were no significant differences
due to affective and ability factors.
