Documenting the Impact of Resilient Playgrounds Projects
The data-based problem-solving steps described in Chapter 4 are a form of action research-collecting data about students’ recess experiences and using that data to refine and strengthen recess routines and practices. This is an example of a very simple but not very powerful research design called a prepost design. Information is collected before a change is made and collected again after a change is made, and the difference between the two times can be used as a rough estimate of the impact of the change. The shortcoming of a pre-post design is that it never really proves what caused an improvement-it simply establishes that the improvement occurred.
