本研究旨在發展適用數理資優鑑定的實作評量，以提供有效篩選數理學術性向 資賦優異學生之測量工具。研究者邀集數學與自然科學領域專家以及資優班現場教 師共同編製數理領域實作評量，共11 題。首先，以49 位國中一年級學生進行預 試，依各試題內部一致性之結果挑選出六道題目（數學科與自然科各三題）為正式 試題。接著，以150 名學術性向測驗百分等級97 以上的國中一年級學生進行正式 施測及信效度檢驗。結果發現，各試題內部一致性信度介於.46至.96，數學與自然 分測驗分別為.77 與.61，整體實作評量則為.77。數學科與自然科之相關係數為 .40，顯示各科具有良好區別性。研究者採用受測者下一學年之學科成績為效標變 項，分析結果指出：實作評量分數可顯著正向預測數學科（r = .29～.40）與自然科 成績（r = .20～.25），表示本實作評量能有效預測受測者後續在數理科目之學業表 現。本研究亦於文末針對測驗信效度以及未來相關應用提出討論與建議。

The study is aimed to conduct the performance assessment for identifying the mathematically and scientifically giftedness (PAMSG). 11 items of performance assessment was developed by the experts and gifted class teachers in the mathematics and sciences field. 49 junior high students participated the pre-test of PAMSG. Six items was selected as formal test according to the higher internal-consistent coefficients. We recruited 150 junior high students whose score of scholastic aptitude test above 97 percentage rank join the formal test. As for the reliability, the coefficients of internal consistency for mathematical and scientific sub-test were .77 and .61, for integrated test was .77. The correlation coefficients between the two sub-tests was .40, indicating the internal discriminant validity. The score of PAMSG positively predicted the subsequent academic performance of the mathematics and sciences discipline. We have discussed the reliability and validity of the PAMSG, and provided the potential application.
