It depends what level the education is happening at. Think of it like students being taught how to do for loops but are just copying and pasting AI output. That isn't learning. They aren't building the skills needed to debug when the AI gets something wrong with a more complicated loop, or understand the trade offs of loops vs recursion.

Finding the correct balance for a given class it hard. Generally, the lower level the education, the more it should be closed books because the more it is about being able to manually solve the smaller challenges that are already well solved so you build up the skills needed to even tackle the larger challenges. The higher the education level, the more it is about being able to apply those skills to then tackle a problem, and one of those skills is being able to pull relevant formulas and such from the larger body of known formulas.
