Guskey (1995) – Teacher change and development is both an individual and organizational process. Teachers are more likely to develop and change in positive ways when the organizational and social contexts are supportive. Focusing on individual change while neglecting organization system level issues can limit success of programs. Organizational changes alone might not result in changes in teachers practices or student learning. [p. 119]
Teacher beliefs are more likely to change after trying out new instructional strategies and experiencing some sort of success.
