Check out I Education Apps Review Ning to talk with app developers and teachers.  TJ has a great example here of the power of bringing these two categories of people together... Check out his post at: Looking for some Feedback.

Hi folks,

Just looking for some educator feedback to assist in updates and revisions to current apps.

Stoichiometry Simulator
Calorimetry Simulator

Feel free to contact me for promo codes to download the app for free. All I ask for in return is some useful feedback to help shape the apps and continue to make them more useful in the different environments (middle school, high school, college). Also, feel free to pass the request onto colleagues in science departments.

T. J.

Thanks T.J. Let us know if you get some great feedback and help!
