Use Worked Examples Before Solving Problems Alone

There's a persistent myth that struggling with problems from scratch is the best way to learn. For experts, maybe. For beginners, research consistently shows the opposite. Studying fully worked-out solutions first is significantly more effective than diving straight into problem-solving. Trace each step in the solution. Ask yourself why that step was taken, not just what was done. Understand the logic before you try to replicate it.

This is called the worked-example effect, and it works because beginners don't yet have the mental schemas to approach problems efficiently. Struggling without those schemas just produces confusion and frustration. Once you've studied several worked examples and internalized the patterns, then switch to solving problems on your own. You'll find you can actually do them — because you now have a framework to work within.
