I just stumbled across the Sandbox Browser on Apps gone free. I need to try it out and see how it works. The basic premise is that I can go into settings and have a list of sites they are allowed to be at. For me, it might be Mathisfun.com or Coolmath.com. If a student tries to go anywhere else, they will be told that it is not an authorized website. I am hoping that by using this particular browser, it will cut down on the number of students who surf the web rather than doing the actual lesson. I think I saw where the program can disable Safari so that students cannot use that to go around the restrictions.
I know that students going places they should not is a problem in elementary school here so I am going to recommend it to the tech head and see what he says. As I explore it, I will report back on how its going.
