Do you know what is working in your school relative to the strategies being implemented? Effects (e.g., state and local related data) are often studied, but do you know the causes? Specifically, what strategies are being implemented that work for the population of students in your school? How do you know they are successful? Our approach to evidence-based instruction works to connect both the effects and causes of student learning as a means to determine successful instructional strategies based on the evidence that ties these strategies to student learning results.
