This document discusses professional development (PD) practices and strategies. It notes that there is no single most effective PD method and that practices are interrelated and must be integrated. It outlines best practices like mentoring, peer coaching, hands-on activities, and setting goals. It also discusses frameworks for evaluating PD, including KASAB, TPACK, and comparing linear vs. cyclical models. Key points are that teachers need time to explore new strategies, PD must be tailored to audience needs, and ongoing evaluation and reflection are important for effective implementation and improvement.
