I am officially OLD. I learned about computers when the computers used punched cards. I don't use the control key for commands. I use the menus.
HOWEVER, I am one of the most technology interested people in my building. I love getting a new gadget and wish my district had access to more! I agree with most of the people here that the main detriment to using more technology is time but also interest. Even when the technology is as simple as a network printer, some people do not want to learn how to control the settings. When you are dealing with a person who is unwilling to try to understand something that will fix a problem they encounter daily, it is unlikely that person will ever embrace the technology challenge voluntarily.
I try to overcome the hurdles by being sneaky. Having those who are reluctant "catch" me doing something they find interesting. Showing by example that slowly we can move forward since even I can do it!
I also think that a big problem is that the technology available keeps changing. A person will learn how to do something with the hardware they were given and now there is new hardware with new ways to control it. After a few cycles of this some just give up and don't want to invest themselves over and over again.
One last thought - Are we sure that using ALL of the technology available will actually advance student learning or is it just more entertaining than filmstrips?
