The researchers used the findings, which have now been published in Review of Educational Research, to develop a series of free, online and asynchronous professional development courses for teachers. The courses were provided online to more than 1,000 teachers during the early years of the pandemic.

"We've learned a lot about what works for online instruction in U.S. higher education, but we wanted to see what works for K-12," said the study's lead author Carla C. Johnson, professor of science education at NC State. "We noticed that many teachers hadn't had any training for online instruction; we have been preparing them to teach face-to-face. Ultimately, we found that some of the strategies that worked well in-person also worked online, with some modifications."
