Developing English language teacher special field proficiencies through lesson study

This study examines the factors affecting the development of specialized proficiencies among English language teachers via a Lesson Study methodology. This action research involved four secondary school English teachers in Turkey. While many studies have focused on general teaching practices, there is a notable gap in research specifically exploring how LS contributes to the development of specialized proficiencies in English language instruction within the Turkish context. This study addresses that gap by offering context-specific insights. The low distribution of eighty percent of the selected class included both students and language teachers who volunteered. The criterion was a class with students of varying achievement levels. So, the study’s participants included four female English language teachers from a secondary school, whose native language was Turkish, the students in the class where the research was implemented, an administrator, and a researcher. The students are included in 16 male and 18 female students. The research included observational evaluation criteria, researcher journals, audio recordings, and semi-structured interviews with educators and students to gather qualitative data. The research sought to strengthen teaching methods in planning, language skill development, evaluation, and professional growth through five iterative cycles of planning, action, observation, and reflection. Research demonstrates that collaborative lesson planning, varied and student-centered instructional strategies, and the incorporation of real-world applications markedly improved teacher effectiveness and student involvement. Educators gained advantages from self-evaluation, peer critique, and professional collaboration, resulting in enhanced pedagogical tactics and classroom methodologies. Students exhibited increased enthusiasm and engagement, especially in activities customized to their preferences. Notwithstanding these achievements, we recognized limitations like inadequate planning abilities, dependence on conventional teaching techniques, and a restricted emphasis on emotional learning goals. Rectifying these deficiencies is crucial for ongoing professional development. Thus, this research advances the field by demonstrating how LS can serve as a practical and reflective framework for enhancing both teaching quality and student engagement in language learning. This research highlights the effectiveness of LS as a framework that promotes the growth of both educators and learners. It underscores the significance of peer collaboration, reflective practices, and innovative methodologies in tackling educational difficulties and enhancing professional competencies.
