The Public Learning Media Labs,
http://www.plml.org, a 501(c)(3) nonprofit, asks teachers to talk about what is hard to teach in order to meet its goal of producing and releasing free educational technologies that address critical national instructional needs.
For instance, many librarians and media specialists told us that web search is hard difficult to teach; so, we developed
http://www.boolify.org as a helpful tool. Recently, feedback teams identified multi-digit multiplication as a critical skill; as a result, we're developing a web tool this August and September, and educators, we need your input!
Getting involved doesn't mean much - answering a couple quick surveys, and then providing feedback into the designs as they become live.

Cheers, and thanks for your support!
