A good deal of research shows that most learning happens when you recognize and back off from an incorrect solution on your own, without outside guidance. So, the key to a good learning environment is setting up scenarios where the backround information is present, and answers aren't out of reach, but there's a bit of struggle to find them.

This is also how you learn to learn, and develop grit. Grit is one of the best predictors of success.

Technology that gives answers or guides heavily is harmful to the learning process.
