Both the quantity and quality of L2 input play crucial roles in second languag e acquisition (SLA). To ensure L2 learners receive optimal input\, tex t readability must be carefully controlled. CEFR B1-level users typica lly work with a vocabulary level of 5\,000 words\, while A2-level user s command roughly half that amount—between 2\,000 and 3\,000 words. Though most data-driven learning studies have focused on advanced lear ners (beyond the B1 level)\, many Asian EFL learners require more cont rolled texts. This principle applies equally to reading concordance li nes. When reading a long passage\, contextual information helps learne rs predict the meaning of subsequent sentences. However\, concordance lines present a unique challenge—each sentence comes from a differen t text\, forcing users to process meaning with far less context than i n regular reading passages. This limited context\, combined with vocab ulary that may exceed learners’\; levels\, creates a significant challenge for understanding how search words are used in context. In t his talk\, I will demonstrate several ways to control readability: com piling textbook corpora\, adjusting sentence-level difficulties using GDEX and other indices\, and filtering texts using CEFR vocabulary\, g rammar\, and text profile information developed for my CEFR-J project.
