School reform is an international phenomenon.
The United States , Canada, Australia, New Zealand, Japan, and Britain have introduced a variety of changes to improve education. The most common concern is teacher development , in recognition of the fact that teachers determine school quality. From the perspective of the school administrator it seems reasonable to implement a formal training program, but some research has shown that large-scale change is unsettling to the entire organization and narrow projects rarely result in significant improvement. In the American research literature it has been found that successful professional development results from teamwork, either teachers in the same schools working or teachers working closely with peers in other schools to accomplish professional development goals. However, teamwork can be counterproductive if some members of the group are negative about the training, a condition that can be created by too much planning, study, and committee assignments rather than actual development activities.
