R Murray Thomas uses inertia theory to describe how educational reform efforts work or don't work in schools.He also uses case studies of reform efforts to illustrate the five themes that emerge from applying inertia to education.The examples are of situations common to most educational settings.The lessons from each example can be applied to a wide range of settings to help educators avoid the pitfalls common to reform efforts.It's a quick and easy read that can be absorbed all at once, or can be used as a reference for specific case studies that apply to each educator's need.
