COSP Classroom Approach:
Research Foundations and Emerging Evidence

Research Foundations for Student-Teacher Relationships

Children who have strong relationships with adults do better in learning environments. Interactions between children and adults are the primary mechanism for development and learning. We know this to be true for a child’s attachment to their parents, but, we also have a solid research base on the influence of a child’s attachment with their teachers. In over 25 years of research, close and secure attachment in the classroom is associated with higher grades, greater emotional regulation, social competence, and willingness to take on challenges. There is evidence that these positive effects are stronger for students who are struggling. Below you can find foundational research and studies supporting the importance of student-teacher relationships in learning.

Research Foundations for Practice-based Coaching

Practice-based coaching (PBC) is an evidence-based approach with early care professionals designed to support teachers’ use of effective teaching practices that lead to positive outcomes for children. PBC includes shared goal setting and action-planning; regular, focused observations; and reflection and feedback sessions. COSP Classroom Coaching supports teachers’ implementation of COSP Classroom concepts and practices in the classroom within the PBC cycle as a way to organize the coaching experience.
