Meet Sean, a creator of AP Physics on Khan Academy | AP Physics 1 | Khan Academy

I have taught AP Physics classes for the last seven years: AP Physics 1, AP Physics B back in the day, and AP Physics C now. I try to make my lessons personable, relate to the student, and offer them real-life examples where things happen. But I also focus on, instead of a bunch of little memorization facts, like what's the big idea that helps you figure out all these different situations.

This approach allows you to be more of a robust problem solver. So, we're focusing on the big core ideas of our subject—being physics. I think you'll find that across all the different AP content subjects, we are finely tuned to what the AP exam is going to be like directly. We are building in videos for instructions specific to that, and we also have practice exercises that I'm really excited about.

You can assign these to students, and there are hints and feedback: why a certain problem is wrong and why a certain problem is right. Then, it shows you the solution path of how you would get to the solution. So when you assign a student a problem, they don't have to wait a whole 24 hours until they get back to class. They can get it wrong, fail early, try another one, fail often, and do it a couple of times on that.

I actually think my students might do more homework because they're getting instant feedback on the process. Rather than just trying a couple and getting stuck, feeling frustrated and saying, "I'm out of here,” they can really get in the seat and stay in there because they're getting instant feedback and help as they're working through problems. I think that's going to be really powerful.
