학습자의 수준에 맞는 읽기 텍스트는 학습자의 읽기 능력 향상에 도움이 된다. 학습자에게 알맞은 수준의 읽기 텍스트를 제공 하기 위해서는 이독성 연구가 활발히 이루어져야 한다. 하지만 한국어 교육에서의 이독성은 양적인 부분과 질적인 부분 모두에서 연구 성과가 미미하다고 볼 수 있다. 이에 본 고에서는 텍스트의 난이도를 측정할 수 있는 이독성 공식의 개발을 목적으로 공식 개발의 기준이 되는 어휘와 문법 항목을 선정하고 어휘 기대요인을 선정하고자 한다.

This study has selected the expectation factors of the list of lexical and grammatical items with an aim to develop the readability formula, which is the statistical assessment of the effect of vocabularies, grammatical items and the expected factors on the standard paragraph. Creating this readability formula requires the criteria to select lexical and grammatical items, and most preceding researchers selected them under the influence of readability studies on English and Korean. Against this backdrop, this study has selected lexical and grammatical items that serve as the bases of the readability formula as well as the vocabulary expectation factors. This study has examined the vocabularies and grammar items studied by some official institutions on a national level and selected the lexical and grammatical items Han Song-hwa(2015) and Yang Myung-hee (2015) as the most reliable ones as well as the lexical expectation factors. The lexical and grammatical difficulty and the expected factors are critical elements that have a direct effect on analyzing the degree of difficulty for text. Studying the readability of the Korean language without the objective criteria is subject to a risk of bringing the result tailored to the researcher's objective. With this in mind, this study has set the criteria for lexical and grammatical items, and lexical expectation factors. This study will pave the way for more objective and reliable follow-up studies for readability of the Korean language.
