Describing LiveCode

Richmond:
I have had pretty much the same history as you,  but started with punch cards on a mainframe less powerful than my thermostat. But, perhaps if you break it down like the kinds of knowledge that a programmer needs:

1. the flow and logic of a program (which applies to all platforms)
2. object oriented programming.
3. strategy and organization of code
4. a need to get kids interested with immediate rewards.
5. the evolving nature of authoring platforms

Once you make these items clear, you might ask whether it is the language syntax that is important, or the organization of that syntax to create an outcome. The syntax is much more straightforward to learn than the organization.

Will livecode help students learn to code in other languages? Of course it will. Only the syntax is different. Piece of cake!

Good luck!
Bill
