A systemwide approach offers the best chance of reaching the most students.The US public-education system is struggling to meet the needs of its students.1 Even among those who graduate from high school, only 42 percent are properly prepared for college.2 And success depends on more than just traditional academic performance: more than 60 percent of all positions in the economy involve knowledge work by people who rely heavily on critical thinking, creativity, and interpersonal skills.3One promising way to improve outcomes is to offer personalized learning, a teaching approach aimed at addressing the individual educational needs of students. Research into personalized learning first emerged in 1984 when the educational psychologist Benjamin Bloom challenged the academic community to replicate, at scale, the effectiveness of one-to-one or small-group tutoring. Bloom found that students who received personalized instruction outperformed 98 percent of those who did not.
