Supporting teachers’ professional development in the social classroom dynamics domain with lesson study

Purpose: Despite their pivotal role in classroom social dynamics, teachers are not always aware of, and/or do not know how to respond to, bottlenecks in these dynamics. This study investigated the effectiveness of the Social Classroom Dynamics Intervention with Lesson Study (SKILS, acronym of the Dutch program name) in supporting teachers with regards to improving their classrooms' social dynamics. Design/methodology/approach: A sample of Dutch secondary school classrooms was divided into five SKILS classrooms (n = 86; 53.5% boys; M_age-T0 = 13.62 years and SD = 1.02 years) and nine control classrooms (n = 156; 50.6% boys; M_age-T0 = 13.55 years and SD = 0.89 years). Involvement in bullying and social cohesion was assessed pre- and post-intervention using student peer reports. Teachers of SKILS classrooms formed SKILS teams of five teachers (N = 25; 60% male; M_age-T0 = 42.45 years and SD = 12.81 years; teacher's experience: M_T0 = 11.35 years and SD = 8.36 years). Teachers were interviewed post-intervention. Findings: While SKILS had little effect on classroom bullying dynamics, it had a positive effect on student social cohesion. Teachers indicated a learning effect with regard to identifying bottlenecks within classroom dynamics and felt more competent to intervene in response to bottlenecks due to SKILS. Originality/value: The findings suggest that teachers can successfully impact classroom social cohesion by increasing their knowledge of classroom dynamics and working in Lesson Study (LS) teams with colleagues to develop tailored interventions for these dynamics.
