As schools are making significant investments in education technologies it is important to assess whether various products are adopted by their end users and whether they are effective as used. This paper studies the adoption and ability to promote usage of one type of technology that is increasingly ubiquitous: school-to-parent communication technologies. Analyzing usage data from a Learning Management System across several hundred schools and then conducting a two-stage experiment across fifty-nine schools to nudge the use of this technology by families, I find that 57 percent of families ever use it, and adoption correlates strongly with measures of income and student achievement. Although a simple nudge increases usage and modestly improves student achievement, without more significant intervention to encourage usage by disadvantaged families, these technologies may exacerbate gaps in information access across income and performance levels.

Nuding技术的使用：来自学校信息系统的描述性和实验性证据

由于学校在教育技术上进行了大量投资，因此重要的是要评估最终用户是否采用了各种产品，以及所使用的产品是否有效。本文研究了一种越来越普遍的技术的采用和促进使用的能力：学校到家长的通信技术。分析来自数百所学校的学习管理系统的使用数据，然后在59所学校中进行为期两个阶段的实验，以推动家庭使用该技术，我发现57％的家庭曾经使用过该技术，并且采用率与该技术有很强的相关性与收入和学生成绩的度量。尽管简单的轻推可以增加使用量，并适度地提高学生的学习成绩，但如果没有更大的干预措施来鼓励弱势家庭使用，
