Such practices can be paired with other opportunities for deepening practice, including observing fellow teachers and working one-on-one with classroom-based "coaches," or content experts (Keller, 2007).

The lesson is observed and sometimes videotaped so that colleagues can analyze the lesson's strengths and weaknesses and determine how to strengthen the lesson (Viadero, 2004).

Unsurprisingly, the complex nature of those transactions renders the field of professional development a challenging one to study. Much of the research conducted on professional development continues to be descriptive rather than quantitative (Sawchuk, Nov. 10, 2010c). "
