To better understand the practices that teachers employ to personalize instruction and the attitudes or experiences that shape those strategies, the EdWeek Research Center surveyed nearly 600 pre-K-12 teachers. The nationally-representative survey, conducted in July and August of 2019, gauges teachers' overall attitudes on the personalized learning movement. It also examines their views and experiences regarding several key factors affecting implementation: technology's role, professional development and support, and day-to-day classroom practices.
