本研究是在一自行建構完成之線上適性測驗系統，進行國民小學線上適性測驗相 關研究，以了解此系統實際運用時，系統之效能與學生們對線上適性評量之接受程度，並探 討做答中給予回饋，對考生由腦態度所造成之影響。本實驗共隨機選取307名五年級學生 （男生162人，女生145人）進行實驗，實驗結果顯示；本系統可同時容納至少40人用，符 合一般學校需求（一間電腦教室容量），受試學童所得能力估計值與其在學自然科成就達顯 著相關（0.625），顯示本系統極具實用性；此外，對於不同回饋方式對電腦態度則無顯著 差異，但不同性別，在實施多媒體線上適性測驗後，則有顯著差異，男生較女生有正向的由 腦態度，整體而言，學生們對線上適性測驗均有高度興趣與接受度，並未產生排斥心態，對 多元評量研究領域而言，為一值得推展之技術。

　　　　　This research, based on the designed on-line adaptive testing system, is to study the performance of the adaptive testing system and the educational research on the primary schools after applying the on-line adaptive testing system. The educational research is to explore the computer attitude of students for the feedback during the testing on computers. Those are 307 elementary school students (162 boys and 145 girls) randomly selected from two schools. The experimental results showed that the proposed system could be operated simultaneously by more than 40 students and it could be satisfied by most elementary schools for using on the class (since, in general, the maximum number of students in the computer classroom was 40). The coefficient of correlation between the ability estimation scores and the achievements of tested students' mature science in schools is 0.625 and it reaches a significant level. The computer attitude is also distinguished for different sex. The computer attitude for boys is better than that on girls. However, it does not reach the significant level between the boys and the girls on computer attitudes for the different ways of feedback. In general, all students had high interest in and high acceptance to the adaptive on-line testing. It will be very useful to apply the adaptive testing as a test style in the primary schools.
