Lesson Planning with Unpredictable Learner Profiles in Japanese Senior High Schools: A Reflexive Autoethnographic Application of SLA Frameworks

This article explores the challenges of lesson planning for English as a Foreign Language (EFL) in Japanese senior high schools (SHS), where Assistant Language Teachers (ALTs) must adapt to unpredictable learner profiles shaped by test-driven pedagogy, variable proficiency levels, and diverse classroom assignments. Drawing on the author’s four years of experience as a JET ALT trained in Communicative Language Teaching (CLT), a reflexive autoethnographic approach is used to develop a streamlined lesson planning template grounded in Paul Nation’s Four Strands framework and informed by work on Multiple Intelligences, social constructivism, Content-Based Instruction, Task-Based Language Teaching, and Presentation–Practice–Production. The template structures lessons into three adaptable stages, featuring activities such as word searches, dictations, and scrambled lyrics to foster engagement, balance skill development, and accommodate classroom variability while prioritizing real-world relevance. Implementation results indicate reduced learner disengagement and enhanced communicative participation across proficiency levels, offering a practical tool for EFL instructors in similar contexts. Reflections highlight the template’s role in reconciling communicative goals with exam pressures and suggest implications for broader SLA-oriented practice.
