The document outlines a study that examines the use of graphic organisers to improve L2 reading comprehension among Japanese undergraduate students. A mixed methods approach is used, including quantitative and qualitative data collection. Students are assigned to either a treatment group that uses graphic organisers during reading or a control group. Both groups complete pre- and post-tests and a survey. The treatment group's use of graphic organisers, students' attitudes, behaviors, and perceived comprehension are observed and assessed. The goal is to determine if graphic organiser use improves actual and perceived reading comprehension, and to gain insights from qualitative data. Materials developed include reading texts, mapping templates, tests, and observation protocols.
