My current position in education is a TIS (technology integration specialist). I am to assist teachers with learning how to integrate technology into their curriculum. But my #1 enemy is "age" or technology frustration.
First, most of the teachers I work with are 40 or older. With these teachers I have to battle against the idea of "well I've done it for years this way...why should I change?" For instance, our county recently adopted a new program that is an online gradebook. It allows the teacher to keep a traditionally type of record keeping while allowing the program to automatically sync itself with the state grading system and allow parents to access their child's grades at any time. Many of the teachers I have tried to help with this refuse to do it or are doing it plus the old way.
2nd, many teachers, no matter the age, become apathetic to the use of technology because of the many glitches you can encounter. My teachers will experience maybe a frozen program or a printer that needs reset, and that will turn them off to all technology forever.
