These are the appendices for the report "Study of Teacher Coaching Based on Classroom Videos: Impacts on Student Achievement and Teachers' Practices. Evaluation Report." This report examined a promising strategy for individualized coaching: professional coaches--rather than district or school staff--providing feedback to teachers based on videos of their instruction. Feedback based on videos gives teachers the opportunity to observe and reflect on their own teaching and allows coaches to show teachers specific moments from their teaching when providing feedback. For this study, 107 elementary schools were randomly divided into three groups: one that received fewer highly structured cycles of focused professional coaching during a single school year (five cycles), one that received more (eight cycles), and one that continued with its usual strategies for supporting teachers. The study compared teachers' experiences and student achievement across the three groups to determine the effectiveness of the two versions of the coaching. This document provides additional details on the coaching provided for the study, the approach to carrying out the study, and the findings presented in the report. The following three appendices are included: (1) The Study's Video-Base Coaching for Teachers; (2) Study Design, Data Collection, and Analytic Methods; and (3) Supplemental Exhibits and Information on Study Findings.
