Abstract：

The purpose of this study was to use the five spatial ability indicators and twelve spatial ability scales constructed by Fong-Mei Kang et al., in order to set the spatial ability norms for industrial vocational high school students from northern, central and southern Taiwan. First our subjects were given spatial ability tests. Then we used the norms to analyze and develop a Spatial Ability Computerized Adaptive Test System for industrial vocational high school students, using the study results as a reference for teaching spatial ability to students in Taiwan and for developing future spatial ability tests.
This study sampled and tested 6,153 students in 19 public industrial vocational high schools in Taiwan so as to collect the test materials, give the spatial ability test and construct the spatial ability percentile rank norms for the students, including the contrast between primary score and percentile rank of each one taking the test. Meanwhile, expert panel discussions and specialist interviews were held to integrate Items Response Theory (IRT) with our own research, and to set up a website (http://sa.ie.ntnu.edu.tw) focusing on spatial ability and the Computerized Adaptive Tests (CAT) system. On-line tests were conducted to record the scores of website users, so as to build a database for spatial ability norms as well as evaluate the spatial ability of users of this computerized system.
