Call for participation in online experiment in educational materials

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?

Many hands make light work. Through numerous contributions from numerous contributors, sites like Wikipedia have developed into valuable resources for educators. I am conducting a study that explores some aspects of offering a similar system for mathematics instruction. Would you like to participate?

This experiment takes place entirely over the web. You will be supported by a software tool to help you create instruction to teach math to struggling students. With your optional consent, the materials you make will be made available to other teachers and their students. You must be 18 or older to participate.
