Cimarron Middle School, United States

Used CK-12 Foundation for 7–12 months

Dec 2020

With CK-12 being FREE and readily available, I am telling many about the resource.

Casey Hackman found CK-12 Foundation:
  • Moderately improves attainment
  • Significantly builds student knowledge
  • Significantly improves teaching efficiency and productivity
    When I want students to grapple with a concept, CK-12 has already done the research for a particular topic.
  • Significantly reduces teacher workload
    I can easily pull up a chapter and it supplements what I am currently teaching.
  • Significantly saves school money
