Good teachers are lifelong learners and want to meet the needs of all of the students in the classroom. Yet, they never have all the answers. Many teachers have found themselves in a predicament of uncertainty and have become apprehensive about their own practices. They can benefit from professional development and supports. Through collaborative learning, they can help each other in learning and implementing new techniques and strategies. Ongoing professional development is mandated in many states and teachers are expected to participate in a variety of forms of professional development. Yet, in a survey of teachers, only 27% of teachers who engaged in professional development in the area of student discipline and management in the classroom found it to be useful. How can teachers ensure that their time is well spent in meaningful training and how can they translate what they have learned into appropriate action within their classroom? It is one thing to participate in professional development; it is another to implement that knowledge within the classroom to make a positive difference in the lives of children. This article addresses the many opportunities from which teachers can choose, and ways to implement meaningful professional development that teachers can use to improve their own classroom environments, as well as those of their colleagues.
