Adaptive expertise is like when you learn how to ride a bike. At first, you need someone to hold you up and help you pedal. But after you practice, you become an expert and can ride your bike by yourself without falling.
But adaptive expertise means that even if you come across a new and different type of bike, like a mountain bike with different gears and brakes, you can still figure out how to ride it well. You use what you already know about bike riding and adapt it to the new bike.
It’s like if you know how to build a sandcastle, but then you go to the beach and the sand is wet and harder to work with. Instead of giving up, you adapt your skills and use a different technique to build the sandcastle.
So adaptive expertise means that you can take what you already know and adjust it to new, unexpected situations. It’s a really great skill to have because you can keep learning and improving even when things change.
