Districts are struggling to accelerate students’ learning, support their health and wellness, and close the achievement gap. Labeled “worst” in 1987, by 2017 Chicago Public Schools was among the nation’s most improved school systems. Chicago’s story embeds many lessons about system change. Sharon Greenberg and Anthony S. Bryk illustrate how local research evidence helped leaders target a few high-leverage processes and informed their ongoing efforts to improve outcomes. Achieving quality enactment of these processes at scale depended on building capacity, which, in turn, took time.

改变学校系统改进叙述

各学区正在努力加速学生的学习，支持他们的健康和保健，并缩小成绩差距。1987 年，芝加哥公立学校被贴上“最差”的标签，到 2017 年，芝加哥公立学校已成为全美改善最好的学校系统之一。芝加哥的故事包含了许多有关制度变革的教训。莎朗·格林伯格 (Sharon Greenberg) 和安东尼·S·布赖克 (Anthony S. Bryk) 阐释了当地研究证据如何帮助领导者瞄准一些高杠杆流程，并为他们持续努力改善结果提供信息。大规模实现这些流程的高质量实施取决于能力建设，而能力建设又需要时间。
