Most teachers only experience traditional, workshop-based professional development, even though research shows it is ineffective.
The reason traditional professional development is ineffective is that it doesn’t support teachers during the stage of learning with the steepest learning curve: implementation.
employing a teaching strategy in the classroom is more difficult than learning the strategy itself
studies have shown it takes, on average, 20 separate instances of practice before a teacher has mastered a new skill, with that number increasing along with the complexity of the skill (Joyce and Showers, 2002).
