Distance learning spans U.S. K–12, postsecondary study, and workforce training, shaping learning at home and on the go. Here we break down participation and growth: 24.0 million Americans took an online course in 2021, while 1.9 million K–12 students were enrolled in full-time virtual schools in 2020–21. We also cover what organizations changed and what research shows about outcomes, engagement, devices, and support as global e-learning and virtual classroom markets expand.
Key Takeaways
- 24.0 million Americans took at least one online course in 2021 (number of people).
- 1.9 million K-12 students were enrolled in full-time virtual schools in the U.S. in 2020-21 (enrollment count).
- 19.0% of U.S. postsecondary students took at least one distance education course in 2020 (percentage).
- $240.0 billion was the global e-learning market size in 2022 (market size).
- $399.0 billion is projected for the global e-learning market by 2026 (forecast market size).
- $56.7 billion was the global virtual classroom market size in 2023 (market size).
- 90.0% of surveyed educators said their students had difficulties with online learning during the pandemic (share reporting difficulty).
- In a randomized controlled trial, using an adaptive online math platform improved learning by 0.19 standard deviations compared with control (standard deviation effect).
- A meta-analysis found that blended learning improved learning outcomes by 0.47 standard deviations on average compared with traditional instruction (effect size).
- A 2021 global survey found that 53% of students used a mobile phone as their main device for online learning (share).
- 76% of enterprise organizations adopted some form of remote work enabling tools during COVID-19, supporting distance-learning operations (share).
Online learning expanded fast in 2020 and 2021, with clear performance gains from adaptive and blended approaches.
