Most of my courses were very "Point A" to "Point B". You're given a set of formulae, then a problem, then you use some combinations of those formulae to solve the problem. Most labs were the same way: you're given an exact script to follow without any explanation of the experiment design. It felt like both were optimized for easy instruction / grading and not for learning new skills or concepts.

Only two of the courses I took were substantially different. One was an upper division lab that actually was more open-ended, where we were given a goal and some equipment and had to figure out how to use the equipment to meet the goal. Another was a more conceptual course where we explored how to approach broad problems to come up with rough estimates for a wide variety of questions. Both were much more engaging, but I saw many students good at the typical course type struggle with how open ended these courses were.

Well, a lot of places would penalize you if your data is incorrect, so most of the focus ends up on execution rather than the why. If you were angling for a high GPA for whatever reason, you cannot afford to experiment too much during lab work. It's another case entirely of course if you are conducting research.
