The development of the MEL-VIS application involves the design of the Visual Learning Application Iteration-Evolution Development Model, MEL-VIS (PIEMEL-VIS), the MEL-VIS ID Model, and the MEL-VIS Application Module. The development methodology and ID model are built based on the application of various components such as learning theory, a visualization approach, a play-while-learning approach based on scaffolding techniques, as well as interaction and interface based on various touch technologies using tablet computers.
