Technology needs to be part of everyday life. I think as educators, we are still struggling with because we are not used to it being an everyday part of our life like the students we teach. We have a lot of things to accomplish with our kids in school and adding that extra technology tool we are not able to do it as quickly as we would like to. Hopefully we will learn how to use this new tool well and faster than we have in the past. Teachers will not be replaces by computers or software.
Students prefer to face to face.
The only place I see the Internet and DDN helping out is where there are holes and needs not being met. That might be a class I can't get and need a higher level of foreign language or mathematics. Just knowing from research that learners want to be with other learners. The closer you are to face to face contact real person contact that's where people want to be. They will tolerate the other things to get what they need.
