I think that technology in the classroom makes classroom interaction better and increases response time, but I do think that if we are not careful it could affect your personal boundaries. For example, I teach in classroom and online classes and I have noticed in both that students will tell me that they expect a teacher to respond to them within an hour via the internet, just this week I had a student in my online class tell me to review his work ASAP (which did not happen by the way). This need for constant communication must be balanced with appropriateness or we lose site of our own personal boundaries, and unfortunately, I have noticed that many Generation Y'ers don't like being told that they can not get their way immediately :)
