The first few years of teaching are rough. Struggling with how to teach, what to teach, how to communicate with parents, and how to navigate the pressures from school administration are common. Many teachers feel isolated, unable to improve, and—perhaps worst of all—unsure of how to improve. Professional development is always a powerful option to help improve teaching proficiency, but only when used judiciously. You have to attend (and participate) in professional development that targets your weaknesses rather than reinforcing your strengths. What options do teachers have when such professional development programs are not readily available, or when they don't know where to begin? The answer: fellow teachers.
