Make educational materials better & win some money

Do you have an interest in mathematics education?

Do you support open access and reuse of educational materials?

Would you like a gift certificate to Amazon?

Volunteers have made Wikipedia a great encyclopedia by creating and improving articles. Our goal is to apply the same model to educational materials. This research is to figure out how the Wikipedia model could work for educational materials.

You will try to improve worked examples that other volunteers have written to provide instruction in understanding and applying the Pythagorean Theorem. A worked example poses a math problem and then shows detailed steps of how to solve it. You will take worked example problems people like you have already contributed and try to make them better. This takes about 10 minutes each.

In addition to helping create better educational materials, you can also win up to $100 in gift certificates to Amazon.com. For each worked example you evaluate and improve, you will be entered into a lottery to win an Amazon gift certificate. High quality contributions triple your odds of winning.
