The thought that rises to the top is comfort level. If a teacher does not feel comfortable with the technology they are less likely to use it. The largest fear would be the unknown, "What If... it doesn't work, or I don't know" To most teachers it just awkward. Some would like to place blame as being incompetent, I disagree. We need to encourage change in small steps so they feel a sense of accomplishment, just as we encourage our students.'
Business handles technology at a faster pace than education. The business has to keep in tune with the competition. Some small businesses refuse to "change", but that keeps there customer base more intimate.
In the end, there is no right or wrong way to embrace change. It just has to be done.
