Novice teachers report feeling unprepared for classroom management following teacher preparation and requested additional support. Evidence-based, preventative, and nonverbal classroom management strategies help teachers develop positive environments and support active learning. This is a study of how novice teachers' feelings of unpreparedness for effective classroom management were shaped. It described ideas of how to best support teachers using interviews and documents from California novice teachers. Findings identified that novice teachers felt unprepared for student behavior issues in the classroom. Inadequate training led to teachers' classroom management deficits including a lack of understanding of preventative, nonverbal, and evidence-based classroom management.
