The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) promotes transparent reporting of data used in both systematic reviews and meta-analysis. Though originally created for the medical research community, it can be used in various forms of research, including educational.

This adapted PRISMA chart shows the number of papers we found in our targeted publication venues. From these, we initially read each abstract, and if necessary, the paper, to understand if it met our criteria for inclusion into our database. A small number of articles have been submitted for review by authors, and we also vet these as well.

This chart reflects data as of August 14, 2020.

Articles identified from the 11 targeted publication venues (n = 7,840) Articles identified through other sources, including submissions by users (n = 0) Articles after duplicates removed (n = 7,840) Articles screened (n = 7,840) Articles excluded (n = 7,184) Full-text articles assessed for eligibility (n = 656) Full text articles excluded, with reasons (n = 0) Articles included in CSEdResearch.org database (n = 656)
