Meeting global demand for growing the science, technology, engineering, and mathematics (STEM) workforce requires solutions for the shortage of qualified instructors. We propose and evaluate a model for scaling up affordable access to effective STEM education through national online education platforms. These platforms allow resource-constrained higher education institutions to adopt online courses produced by the country's top universities and departments. A multisite randomized controlled trial tested this model with fully online and blended instruction modalities in Russia's online education platform. We find that online and blended instruction produce similar student learning outcomes as traditional in-person instruction at substantially lower costs. Adopting this model at scale reduces faculty compensation costs that can fund increases in STEM enrollment.

在线教育平台扩大了大学 STEM 教学规模，以更低的成本提供同等的学习成果。


为了满足全球对科学、技术、工程和数学 (STEM) 劳动力不断增长的需求，需要解决合格教师短缺问题。我们提出并评估了一种模型，通过国家在线教育平台扩大经济实惠的有效 STEM 教育机会。这些平台允许资源有限的高等教育机构采用国内顶尖大学和院系制作的在线课程。一项多站点随机对照试验通过俄罗斯在线教育平台上的完全在线和混合教学模式测试了该模型。我们发现，在线和混合教学以低得多的成本产生与传统面对面教学相似的学生学习成果。大规模采用这种模式可以降低教师薪酬成本，从而为 STEM 入学人数的增加提供资金。
