In this article, the author describes collaborative work with four teachers through the Lansing School District's participation in a multiyear project to implement and study the effects of the My Teaching Partner-Secondary 1:1 Video Coaching model. The model is a collaborative, individualized coaching program that focuses on effective teacher-student interactions that contribute to students' social and academic gains. Based on research and shown to be effective in two randomized control studies (Allen et al., 2015; Allen et al., 2011), My Teaching Partner-Secondary uses a standardized process that is strengths-based, interactions-focused, collaborative, and rooted in a teacher's actual practice. The coaching model is content-adaptable and can be applied to any subject area. The primary goal for participating teachers is to improve their teaching through becoming a better observer of their own practice, specifically understanding and describing interactions, intentionally planning greater learning opportunities for students, and improving curriculum implementation (Pianta et. al, 2010).
