technology for classroom

With no actual teaching experience, I am finding it challenging to evaluate different technologies for my classroom. I can see limited pieces of the puzzle. I was shocked thismorning by a simple process called portfolio assessment. I would have skipped over it as boring. After watching a short video and seeing the process in action in an actual classroom, I have a whole new perspective. I am wondering about my ability to assess anything at all. Even if I had a classroom, I feel like there are so many worthwhile tools and processes, how can I ever master them all. I bookmark everything that I think might someday be helpful, because I do not know how I am ever going to remember all of this.
