臺灣審定版國民小學英語教科書適讀性研究與應用

Research on and Application of Readability of Approved Elementary School English Textbooks in Taiwan

教科書開放使用審定本後，在出版業者製作教科書或學校選用教科書方面，皆需要一個較客觀、簡便的評估工具。國外廣泛採用適讀性作為評估教材之工具，但是臺灣鮮少針對國民小學教科書做適讀性評估。本研究欲探究目前通過審定之各版本國民小學英語教科書的適讀性，針對公式評估之結果，找出可直接適用於臺灣之國民小學英語教科書的適讀性公式。藉助Fryinator 適讀性軟體分析變數值，並套用Flesch 公式、Fog 指數、Flesch-Kincaid 公式、MOG 公式4 個有效公式及Fry 適讀性曲線圖來檢測臺灣審定版國民小學英語教科書的適讀性級別程度。以各版本教科書設定之難易度為標準，找出評估結果完全符合該難易度之公式。研究結果顯示，國外常用之公式無法正確評估臺灣國民小學英語教科書之難易度，臺灣並無符合審定標準之適讀性公式，故建置一套適用之公式有其必要性。

Since it became possible for textbooks to be published by private-sectorpublishers and be approved by the government, it has become obvious that weneed more objective and simple evaluation methods not only for publishers,but also for schools. In many countries, readability is widely adopted as anevaluation criterion; however in Taiwan, the elementary school English textbooksare rarely evaluated according to readability. The present research examinesthe readability of different versions of elementary school English textbooks.The main purpose is to find a readability formula that can be used toevaluate elementary school English textbooks in Taiwan. In doing so, Fryinatorreadability software was employed to analyze variables, and four effective formulas(Flesch Reading Ease, Fog index , Flesch-Kincaid readability formula,and SMOG formula) were used to test grade level readability. By comparingthe difficulty scale proclaimed by each textbook, it's expected that a formulacan be used to account for evaluation results. The results show that the formulasfrequently used to test readability are unable to correctly evaluate the difficultyscale of the textbooks. There is no readability formula which correspondsto the textbook evaluation criterion in Taiwan, therefore, a suitable formulaneeds to be established to evaluate elementary school English textbooks inTaiwan.
