Description

This study analyzes 24 series of MEXT-approved high school English textbooks (70 books) under the latest Course of Study (2021). Vocabulary coverage was examined using NGSL, NAWL, UWL, TSL, and JACET 8000, Word List. Results show that while NGSL is largely covered, academic and technical lists are less represented. Considerable variation exists among textbook series, suggesting that the choice of textbook may significantly influence students’ vocabulary acquisition.
