Abstract
This paper is an action research conducted on the effective use of the author's instructions and self-made visual materials within the Japanese language teaching practices at the Graduate School of Global Communication and Language, Akita International University. During the practicum conducted in the fall of 2023, basic and practical exercises were carried out for beginner Japanese learners. However, the author's intentions implied by her instructions were not fully understood by the learners, so that they were unable to smoothly engage in the practice activities. The analysis revealed that negative factors included ambiguous instructions by the author, a lack of explanations of necessary information and procedures for activities, and insufficient utilization of visual materials. Based on these issues, this paper examines the trends in the author's instructions and self-made visual materials, and proposes improvements for effectively using visual materials and providing instructions that beginner Japanese learners can understand.
