日本語読解力と英語運用能力に通底するアカデミックスキル（グローバル時代を生きる教科横断型の総合力としての言語運用能力の検証）

抄録

In the global era, language skills are considered a fundamental competency underlying all areas of learning. This study investigates the relationship between Japanese language literacy and academic English proficiency by utilizing the Reading Skill Test (RST) and the TOEFL Junior (TJ). The analysis reveals a strong correlation between TJ scores and performance across five core subjects (Japanese, Mathematics, Social Studies, Science, and English), as well as with specific ability scores measured by RST. These findings suggest that language skills are not confined to language subjects but function as a common foundation required for learning across all academic disciplines.
