Teachers' capacity to create inclusive learning environments

Purpose The purpose of this paper is to explore effects of an intervention designed for teachers' learning. This study investigates the effectiveness of a three-session professional development (PD) program based on the lesson study methodology. Lesson study was chosen as an intervention, attempting to strengthen teachers' awareness of and readiness to teach for student diversity. Design/methodology/approach This study included 26 participants. The teachers took part in lesson study cycles during a period of four months. Effectiveness was measured using a pre-test/post-test within-subject design. The broad concept of inclusion and the characteristics of the research questions in this study demanded a mix of methods, a design in which qualitative and quantitative data are collected in parallel, analyzed separately and then merged. Findings Results show an increase of teachers' readiness from baseline to post measurement to adjust the learning environment for increased inclusivity. The largest increase (88%) was seen in the themes in teachers' responses regarding accommodations for a student with special needs. Regarding self-perceived ability, the average increase was 50%. Results show significant changes in teachers' adjustment awareness ability. Originality/value This study contributes to educational research, as the focus is PD for general teachers. PD opportunities with teaching strategies related to special needs (e.g. neurodevelopmental conditions, NDCs) are seldom offered to general education teachers. Support from teachers is a key strategy for accommodating students with special needs in mainstream classrooms. Furthermore, there is a lack of literature of interventions aiming to improve teachers' readiness and preparedness for students with NDCs in mainstream settings.
