For any student in VizZle prior to VizZle 4.7 a Student Player folder was automatically created. Putting lessons in the Student Player folder was how you made them available when the student logged into the VizZle Player.
Now it is even better!
Every folder can now be a VizZle Player folder. By default if your student had a Student Player folder before the update, that folder is still accessible to the student after the update. You can also make additional folders accessible simply by first selecting the folder you want accessible to the student and then clicking Allow Student Access.
