[Maths-Education] research on using Flash-type demos/tutorials to teach about software?

[Kate Mackrell]

Does anybody know about any such research?  Even better if it's about 
learning to use maths software such as dynamic geometry.

I'm aware of the research on learning objects: this may be a subsection of 
this research, but even so I haven't been able to find anything.

Thanks
