Comments from Educators

I'm a first year teacher in an impoverished school district. Having virtual tools is the best way to close the achievement gap between my district and well-funded schools. Thank you!

I am an italian teacher of chemistry. I like my work and new teaching strategies. Often some of my students can speak English better than italian and as I know how much important english is, I invite them to keep an english lecture on a particular topic for the whole class, including me. Your videos, tests and documents are really helpfull in this! Thank you very much

Ck-12 has always been my study buddy. I like the fact that there is more than one way to learn about something rather than sticking to a typical lecture or textbook. It lets me explore new concepts.
