App Inventor is poised to change the mobile development landscape significantly. Not only does it make it much, much easier for beginners to get their hands dirty and start developing with little overhead or formal schooling/training, it stands to turn merely curious parties into more serious developers as well. The whole enterprise carries a strong stance that “programming can be a vehicle for engaging powerful ideas through active learning,” which is just so in line with O’Reilly. The blocks editor uses the Open Blocks Java library for creating visual blocks programming languages. Open Blocks is distributed by the Massachusetts Institute of Technology’s Scheller Teacher Education Program. The compiler that translates the visual blocks language for implementation on Android uses the Kawa Language Framework and Kawa’s dialect of the Scheme programming language, developed by Per Bothner and distributed as part of the Gnu Operating System by the Free Software Foundation.
