認字自動化指標之建立與信效度研究

本研究的主要目的為探討以字彙辨認作業中的兩項測量指標做為國小學童中文認字自動化評量指標之可行性。其中一個指標為平均反應時問，另一個指標為以刺激字複雜度為預測變項，以反應時間為效標變項之迴歸線的斜率。研究中以重測信度、複本信度、及效標關連效度對這兩項指標進行考驗。研究結果顯示字彙辨認作業中的平均反應時間具有良好的信度與效度，適合做為認字自動化的評量指標。但字彙辨認作業中的斜率則不具穩定度，也缺乏良好的效度，故不適合做為認字自動化的評量指標。此研究結果可提供認字自動化評量系統之建構的參考。

The purpose of this research was to evaluate two possible indicators of character decoding automaticity for Chinese learners in elementary schools. One of the possible indicators was mean latency of lexical recognition task. The other possible indicator was the slope predicting latency from character complexity on the lexical recognition task. The test-retest method and equivalent-forms method were adopted to evaluate the reliability of the two indicators. The criterion-related coefficient was used to evaluate the validity of the indicators. The results of reliability and validity indicated that the mean latency of lexical recognition task was a good indicator of character decoding automaticity, while the slope relating latency to character complexity on the lexical recognition task was not. This finding should be useful in establishing a computerized assessment system of decoding automaticity for elementary school students in Chinese character recognition.
