Today, millions of teachers search online to locate ideas and activities for classroom use.

Leanna Archambault, Catharyn Shelton, and Lauren McArthur Harris highlight concerns surrounding the limited perspectives present in online educational marketplaces and provide research-driven guidelines for educators evaluating resources from such sites.
