Expertise reversal effect

Okay kiddo, have you ever noticed that when you're learning something new, you might not understand it at first but eventually you get better and better at it? Well, this is called expertise! When someone becomes an expert at something, they know a lot about it and can do it really well.

Now, imagine you are learning something and your teacher is an expert in that topic. They know a lot about it and can do it really well too! But sometimes, experts can forget what it was like to be a beginner and they might start using complicated words and ideas that you don't understand yet. This can actually make it harder for you to learn!

This is what we call the expertise reversal effect. It means that sometimes, when someone who is really good at something tries to teach it to someone who is just starting to learn it, they might accidentally make it more confusing for the learner.

So, it's important for experts to remember what it was like when they were just starting to learn and to try to explain things in a way that is easy for beginners to understand! And if you ever feel confused by something an expert is telling you, it's okay to ask them to explain it in simpler terms so you can understand better.
