Schools today are not very different from 50 years ago. Instructors still teach to the average, rather than provide students personalized instruction, because it is expedient, not because it is effective. Most educators still rely on tradition and rules of thumb, rather than use evidenced-based tools and methods to advance student achievement. And most administrators still make decisions, often inaccurately, based on assumptions and intuition, rather than use detailed metrics and analytics to manage schools efficiently and fairly. In short, while most Americans are empowered by data and technology in many aspects of their lives, U.S. schools are largely failing to use data to transform and improve education, even though better use of data has the potential to significantly improve how educators teach children and how administrators manage schools.
