eChalk’s Green Calculator and PolyVision’s eno side by side in TechLearning
TechLearning’s Green (money + conservation) issue in July was kind enough to take notice of both eChalk and PolyVision on the same page, and place eChalk’s phone intro on the cover. If you don’t subscribe to their e-reader (don’t worry, they won’t spam you), you can navigate the issue here. http://www.techlearning.com/section/newsandTrends
