Flipping a classroom allows the students to spend their classroom time with the professor, TA and their peers asking questions to better learn the material in a scaffolded environment. Traditional lectures have them passively listening and doing the learning assignments at home often alone.

These Applets were initially developed at Johns Hopkins University. I think they are wonderful and have been using them in my class. Because most browsers no longer allow Java to be run (for security reasons) the needed to be converted to JavaScript. Students at JHU started the project and I finished it. Here are the results.

I believe that students can learn the material if the practice it. I make my past exams available to students and clearly let them know what is expected of them. Tests should not be tricks. If they can do all these problems, and then ones similar to it on a test, then they have met my learning objectives for the course.
