Outline of Final Research Achievements

The research investigated the accuracy rates of inferencing unknown words attained by learners using short narrative passages with controlled vocabulary levels. The accuracy rates were measured on frequency of vocabulary words, grammatical functions, contextual clues, strategies used from the contexts, and reading comprehension of the texts. The accuracy rates of the target words in the form of non-words varied greatly, probably caused by the characteristics of each target word. The over all accuracy rate of all the target words resulted in similar range as obtained by earlier research results although it was not high. The result of the whole research suggests that for learners to acquire vocabulary words, it probably is necessary to repeatedly encounter the vocabulary items in a variety of contexts.

Academic Significance and Societal Importance of the Research Achievements

外国語学習において、教えるのも学ぶのも、最も困難とされている領域の一つである、語彙習得について、未知語の推論という新しい可能性のある観点から取り組み、言語習得への示唆を得ることができた。語彙習得においては、物語文読解の文脈では、使用頻度や学習者の持つ語彙サイズやそれぞれの語の文中における役割や活用できる文脈の意味など、さまざまな要素の活用が考えられる。一方、未知語の推論における達成度は本研究の他に従来ある研究では、そもそもありま高くない数字が示されてきている。この結果が示唆することは、語彙の習得には、多様な文脈における多数の出会いが必須であるという事である。このことは、英語教育への応用が可能。
