摘要

本研究在發展數學領域電腦化準備度測驗，並應用此測驗來了解嘉義縣市國小三升四年級學生數學先備知識準備度情形。本研究透過分層叢集立意抽樣的方法，選取588位嘉義縣市地區國小四年級學生為對象，進行電腦線上測驗，一方面評估本測驗之信效度，另一方面瞭解嘉義縣市三升四年級學生之數學先備知識之準備情形，以及城鄉地區學生數學準備度之差異。資料經過統計處理與分析，獲得以下的發現：一、本研究所發展的數學準備度測驗具有良好的信效度，其內部一致性係數（Cronbach α）為0.84，平均難易度為0.64，平均鑑別度為0.44。二、嘉義縣市四年級學生在數學先備知識準備度上，有25%的學生未達中準備度。三、嘉義縣市四年級學生在數學先備知識準備度上，有城鄉差異的情況，嘉義市區學生的整體測驗表現顯著優於嘉義縣學生，而嘉義縣一般地區與偏遠地區學生則無顯著差異。

The purpose of this study was to develop a ＂Mathematical Computerized Readiness Pretest System＂ (MCRPS) in order to understand the mathematical prior knowledge of fourth grade students in Chia-Yi area, and compared the students' performance difference between the urban-rural school district. By hierarchy cluster sampling method, this study selected 588 fourth grade students who finished third-grade courses from urban, rural and remote areas for computerized online test to construct the reliability and the validity of MCRPS, and to understand more about the development of the fourth grade students in third grade students' mathematical prior knowledge. Data collections and statistical analyses of this study were concluded as the followings: 1. The MCRPS was reliable and validity. The Cronbach α coefficient of the total scale was 0.84, its average difficulty coefficient was 0.64, and its average discrimination coefficient was 0.44. 2. There were 25% of the fourth grade students in Chia-Yi area didn't get half score in MCRPS. 3. Fourth grade students in various areas of Chia-Yi were significant difference in mathematical prior knowledge, and the students of city area had better performance than the students of county and remote area in MCRPS.
