Flex Programming Concept Metaphor

I am currently following the Cairngorm micro-architecture for rich internet application to develop and architecture my latest app (which will be a desktop AIR app for multimedia recordings). I have been following this excellent series of tutorials by David Tucker. On part 3, David goes through the complete architecture. I have been trying to wrap my head around the different components of it and I think this metaphor makes sense:

View = body (waiting to send message based on impulse)
Event = electrical impulse caused by interaction to the body
Controller = brain that understands all events
Commands = messages sent by brain
Model = Memory that stores states of the body from messages sent by brain
View = body (waiting to receive message and state to react to impulse)

That helped me wrap my brain around the concepts

Project & Performance based learning

I’ve subscribed to an excellent podcast series from www.edutopia.org. I’ve found the attached videos particularly interesting – the power of using real-life projects and cases to help the students internalize & gain mastery in the concepts. There is definitely a place for text-based learning from the teacher and actually this should probably constitute a strong part of the foundation of teaching, specially for cognitive knowlegde. However, project based learning combined with performance based assessments really help in deepening the knowledge by having the students use the knowledge in a controlled environment.

“Tell me and I forget. Teach me and I remember. Involve me and I learn.” Benjamin Franklin

Even more powerful is using projects/cases across different subjects in the same curriculum. It can be very effective, specially for tacit knowledge like change of attitude, character building or problem-solving skills.
