Entry 1D Portifilos

I feel this standard will be a hard one for me for pre-k. I know that I can facilitate knowledge construction and foster creative thinking in a face-to-face enviroment but I am not sure how to do that in a virtual environment yet. It is hard for them to just let them go on the internet all by themselves right now. It will be very time consuming on my part going from computer to computer when they get stuck somewhere and not know what to do. It will not be very productive for their learning. They need an area where they can go section to section like starfall.com. I would just love to find something else at this point though. We always use it because it is free and creates a very productive learning environment. There is no where really to get lost because it sparkles where they need to click to go to the next section. Again, I am still researching and looking continually for another site that will be a great virtual environment for my students.
