Almost every one of us had that one classmate back in school that preferred the images and the illustrations in the textbooks to the text itself. Mainly because they, could easily understand the main idea in this manner, perhaps even without realizing it. And there were some others that may not take notes in class but would pay rapt attention while the teacher explained because it was all they needed.

The 21st century digital classroom on the other hand should be designed and equipped in a way that these individuals that learn differently are not left out. The use of such technology media is what transforms an ordinary team into a smart digital classroom; hence DigiSmart. When a child simply hears the lesson in the voice of his/her teacher, he/she will never be able to visualize and learn as effectively as when he/she does when shown visual clips with interesting voice-overs. Whereas, the effectiveness of live experiments cannot be compared to better than reading about them.
