English reading materials are abundant on the Internet.However, it is still difficultto select proper materials to organize courseware that can be used throughout a one-semester English reading course.We proposed a method for constructing coursewarefrom target vocabulary and corpus.This method was designed to extract a mini-mal set of articles (from the corpus) that contained the vocabulary.We applied themethod to TOEIC (Test of English for International Communication) vocabularyand The Daily Yomiuri newspaper articles.The constructed courseware consistedof articles that had dense occurrence of the target TOEIC vocabulary.The degreeof denseness was measured by comparing various statistics of the courseware withthose of the randomly sampled articles.It was found that the courseware was ef-ficient in presenting the vocabulary to students through reading.It is also used inEnglish classes in one university as supplementary material and has been shown tobe promising
