Introduction to Greenfoot System from the creator of BlueJ the simple application to teach Object Oriented Programming.
When I first installed Greenfoot out of curiosity it did not seemed interesting to me. Now after watching this video I can understand the potential of the system for teaching Object oriented programming to students even of age 14.
The concept where a student get to create something and show off the creation is the most motivating concept.
