Turning Technologies, a leader in audience-response services, announced a service at Macworld last week that brings interactive mobile phone use to the classroom.

Using the company's ResponseWare Web polling application, students can respond to questions from their teachers using the Internet on the iPhone or iPod Touch.

You can download the free ResponseWare software for these devices from the Apple App Store. When students enter the answers on their mobile device, the ResponseWare generates polling slides so the classes can see the results.

The solution is also compatible with RIM BlackBerry and Windows Mobile smartphones and laptops.
