Yes, doing things by hand is another thing to prioritize.

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.

Totally agree! I think the risk within the context of the task is important, if you can work within an environment where you can make mistakes but not cause catastrophic consequences, its a good environment. I think its also great to get to a solution and realize it wasn't the right way to do something, and then iterate, there is not always a need to back off, although intuition over time will be great to notify someone that maybe they are on the wrong track.
