1) The dynamic model of educational effectiveness provides a framework for conducting theory-driven evaluations of educational reforms and policies. It considers factors at the classroom, school, and system levels and how they influence student achievement.
2) Evaluations using this model examine the direct and indirect impact of reforms on student outcomes and the functioning of effectiveness factors. They also take into account the multilevel nature of education.
3) The dynamic model's measurement framework dimensions of frequency, focus, stage, quality, and differentiation can be used to analyze reform characteristics and implementation across different levels. This provides a comprehensive approach for understanding how and why reforms are more or less effective.
