Bootstrapping Forth

I am getting ready to author a series of tutorials on bootstrapping Forth starting with a "blank" microprocessor.

I am doing this as a microprocessor and programming fundamentals mini-course for my son's FRC [0] (FIRST Robotics Competition) club.

The intent is to teach basic digital logic and programming at the lowest possible level as a solid foundation for development at higher levels. Almost any modern language becomes easier to understand once armed with an understanding of low level concepts.

I am looking for input on how to approach it. I've done seminars for working engineers in the past. In this case I have to assume no prior knowledge of any of the material to be presented. At a basic level three approaches come to mind:

    - Text based.  You have to read it.  Slides.
    - Video lectures.  I present on video while showing relevant slides.
    - Interactive.  Like video lectures.  Uses a real-time recording of
      terminal window much more so than pure text slides.

Of course, I'll design and build a little microprocessor board the students will use during the course. Not decided on architecture/processor yet. On simple 8 bit embedded projects I've tended to use various 8051 derivatives. This is one option. I've also used parts from Microchip, TI, Freescale, Cypress and others.

Thanks!
