Rules of Thumb

I am not sure if I am supposed to post my rules of thumb or not, but I will just to be safe and because I have nothing else to do at the moment. So, if I had to pick two rules, they would be:

1)The students should have an active part in the use of technology, as opposed to them just passively watching their instructor.

2) The technology used should serve a purpose in the learning process instead of being used as a way to occupy the students.
