CollegePathway and Academic Express 3 are LMS platforms built on supereigo.com that support multiple English learning goals including TOEIC, EIKEN and university entrance exams. They are used by over 100 institutions across Japan and serve hundreds of thousands of students and teachers. In April 2025, we added Pearson Bank, a repository of 30 graded short stories ranging from abridged classics to original Pearson titles. Each story is accompanied by in platform vocabulary, grammar and comprehension exercises so that extensive reading becomes part of both the student learning experience and the teacher toolkit. This presentation describes the integration process including curriculum alignment and workflow embedding. We examine three months of log data to understand how teachers and students incorporate story reading and how story use aligns with overall platform engagement. This case offers a scalable model for embedding graded extensive reading as a central measurable component of language learning on large scale digital platforms.
