The blog post announcing this new free e-book was published and is hosted on the MIND Research Institute blog.

This e-book is a resource for edtech purchasers. It is all about validity: what are the considerations that should lead into your judgment to trust that a study’s results are externally valid for your situation?

“Every edtech product has a study that says it’s effective. But what are the impact results of that study really saying? How meaningful is the difference between outcomes? And how do we know that difference is not due to chance?”
