"The Missing Link in Educational Technology"

In doing research for EDUC5625 Technology Plan, I ran across this article which, though published in 2002, has some interesting observations regarding the need for effective teacher-tech training. Of particular interest to me was the discussion of cost-of-training.

The authors suggest "a guideline of professional development financing equivalent to 40% of hardware/software expenditures."  If this number holds across a number of other studies, it can act as a clear guide in the development of technology budgets.
