System-wide educational reforms are difficult to implement in the United States, but despite the difficulties, reforms can be successful, particularly when they are associated with broad public support. This study reports on the nature of the public sentiment expressed about a nationwide science education reform effort, the Next Generation Science Standards (NGSS). Through the use of data science techniques to measure the sentiment of posts on Twitter about the NGSS (N = 565,283), we found that public sentiment about the NGSS is positive, with only 11 negative posts for every 100 positive posts. In contrast to findings from past research and public opinion polling on the Common Core State Standards, sentiment about the NGSS has become more positive over time—and was especially positive for teachers. We discuss what this positive sentiment may indicate about the success of the NGSS in light of opposition to the Common Core State Standards.

全系统的教育改革在美国难以实施，尽管困难重重，但改革可以取得成功，尤其是在获得广泛公众支持的情况下。这项研究报告了公众对全国科学教育改革努力，即下一代科学标准 (NGSS) 表达的情绪的性质。通过使用数据科学技术来衡量 Twitter 上关于 NGSS 的帖子的情绪（N = 565,283），我们发现公众对 NGSS 的情绪是积极的，每 100 个正面帖子只有 11 个负面帖子。与过去关于共同核心州标准的研究和民意调查的结果相比，随着时间的推移，人们对 NGSS 的看法变得更加积极——而且对教师尤其积极。鉴于反对共同核心州标准，我们讨论了这种积极情绪可能表明 NGSS 的成功。
