Notes: The pre-Covid sample contains search data from March 2019 through May 2019 in the United States. The post-Covid sample contains search data from March 2020 through May 2020 in the United States. Magnitudes are interpreted as search popularity relative to the popularity of “Google Classroom” in the pre-Covid time period. Search terms are not case sensitive, so “Google Classroom” is equivalent to “google classroom.” The focus of this paper is K-12 online learning resources, so we do not include keywords related to professional services (e.g., Webex), textbooks (e.g., Pearson), or postsecondary (e.g., Canvas), or adult learning (e.g., Masterclass).
