To start with, the thesis mainly discusses the reading comprehension, from the definition of reading and reading comprehension to three different reading models, which shows that the most efficient reading model is interactive reading model, in which schemata knowledge is not only necessary but also important ; after the documentation, the thesis lays its foundation on schemata theory, which involves the different definitions of " schema ", the classification of schemata knowledge and its function in reading comprehension, from which the conclusion is drawn that during the reading, students can use different types of schemata knowledge according to the their language proficiency and different reading materials ; in the following part, the thesis briefly states the relationship between the reading comprehension teaching and the schemata theory, from which i gain inspiration and find out the applications of schemata theory in english reading comprehension teaching in senior high schools ; and at the same time, i offer a reading teaching model of a text, which shows how to use schemata theory in reading comprehension teaching ; in the last part of the thesis, an experiment is done between two classes using two different teaching methods, one is traditional, the other is new, that is, the teaching method that uses schemata theory, which is proved to be far better
論文首先探討了閱讀理解，從閱讀及閱讀理解的定義到三種不同閱讀模式等方面的探討，得出有效的閱讀模式是「相互作用模式」 ，該模式的運行離不開圖式知識的運用；然後，本文介紹了圖式理論，從圖式的不同界定到圖式的分類以及不同圖式知識在閱讀理解中的不同作用，得出：在閱讀中，讀者根據自己的語言水平和文章的難易程度的不同，調用不同的圖式。在介紹完了圖式理論之後，本文還簡述了圖式理論與閱讀教學的關系，探討了圖式理論對高中英語閱讀教學的幾點啟示及其啟示下的具體運用方法，並提供了一篇課文的閱讀教學模式，具體展示了在圖式理論的指導下，如何上一堂閱讀課；在文章的最後部分，筆者在自己所帶的班級中利用將近一年的時間作了一個實驗：在兩個班分別使用不同的教學模式，一個是傳統的教學模式，另一個是圖式理論指導下的新的教學模式。實驗結果證明，新教法的教學效果要好的多。 -
