This presentation examined whether beginner-level students’ difficulties in English performance were solely due to low proficiency or also linked to limited experience in organising ideas. Sachi introduced a structured idea-organisation training approach implemented through a Japanese presentation project with first-year students. By completing multiple presentations and engaging in peer feedback, students improved their ability to organize ideas and increased their self-efficacy in presenting. The session highlighted how these gains in L1 Japanese were expected to transfer to L2 English performance and discussed how the approach could be adapted to different teaching contexts.
