One result of the TDC project was a model for effective and ongoing professional development. This model can be easily replicated or modified to meet the unique needs of individual schools or districts Professional development that leads to significant and lasting educational change can be difficult. It can be frustrating to invest what seems like a lot of time and money in a change effort, only to find a small incremental change in behaviors. Change is multidimensional. We are dealing with change in a school system, and a school system is a very complex entity.
Professional development is an important factor in producing change.
However, by itself, its value as a change agent is limited. Many other aspects of a school system need to be addressed simultaneously to produce significant and lasting change. Change is a slow process. It is the nature of a stable and functioning system to resist change. Many school systems are quite resistant to change, and others will only change slowly.
