The Development and Testing of a Working Memory Performance Task in Mathematical Problem Solving for First Graders

本研究旨在參照解題運作記憶功能（訊息保留及即時處理）分析，爾後搭配學習內容分析，編製解題運作記憶表現作業。採合目標與叢集取樣，抽取嘉義縣市一年級學生施測後進行各統計分析。在效度分析方面，試探性及驗證性因素分析均發現作業的二因子結構（訊息保留及即時處理），且共同向度性、因素萃取、抽取變異比及模式適配度均屬良好，並具良好之效標關聯及預測效度。在信度分析方面，內部一致性係數及組合信度亦屬良好。在區別力分析方面，極端組t考驗結果良好。對不同性別及數學學業成就學生之實測結果發現，二者在兩項能力上均具真正差異。

This study used functional and learning content analysis to develop and test a working memory performance task (WMPT) in mathematical problem solving. The subjects were first graders from Chiayi who were chosen by purposeful and cluster sampling. All subjects were tested with the WMPT， then analyzed by statistical methods. First， the adequate internal consistency coefficient and composite reliability were verified. Second， the results of exploratory and confirmatory factor analysis (EFA and CFA) yielded two factors: information preservation and simultaneous processing. Third， the adequate critical ratios were found for single item tasks， sub-tasks and whole tasks. Finally， performances on the WMPT in mathematical problem solving showed significant differences， especially as a function of students’ gender and level of academic achievement in mathematics.
