Encouraging Teachers, Engaging Students

To see The Source for Learning in action, don’t stop by our offices. Instead, look over the shoulder of a preschool teacher in rural Texas as she confidently assesses the kindergarten-readiness of a dozen five-year-olds. Or watch a third-grade teacher in Pennsylvania navigate a wilderness of online learning tools, in minutes, to discover just the right approach for a lesson on human anatomy. Or shadow a middle-schooler in Atlanta as he pecks out a midnight research paper at his family’s kitchen table. (Last semester, without our backup, he spent his evenings scavenging wi-fi signals at a coffee house miles from home.) 

Exceptional teaching, learning, and professional growth, made possible at little or no cost. That’s what we do.

The Source for Learning:

  • Rich, reliable content—created, curated, and aggregated by professional educators
  • The web’s foremost collection of K-12 learning resources
  • User-centered professional learning, with topics for early childhood through high school.
