Setting Up a Classroom Network
Please download this technical guide to help you set up a classroom network using SimCalc MathWorlds® for Computers.

The first time you launch the software, you'll be asked to choose a language (a dialog will prompt you). Once you have chosen the language, SimCalc MathWorlds® will re-launch itself. You will not see this dialog on subsequent launches.

User Level
When you install SimCalc MathWorlds® for Computers, the software is set to "full" level, which presents the user with full access to the software. When you purchase a license, you will be provided 2 keys – "full" and "standard". Standard level is a simplified version of the software, which takes away access to classroom management and authoring capabilities; this level should be used for student computers.

Known Issues

  1. Users with MacOS 10.5 Leopard on non-64 bit (non-Intel Core 2 Duo) machines will see choppy animations if any of their graph, world, table or function windows are overlapping. If you see this problem, minimize the views you are not using and arrange the windows so that they do not overlap.
  2. Double-clicking to open a MathWorlds document sometimes opens the default document instead. Use the Open menu in the application to avoid this problem. [857]
  3. When using laptops to do connectivity "Sleep Mode" can sometimes interfere with communications if it cuts power to the network card. For connected classrooms it is best to disable any sleep or low power modes.
  4. Teachers may not be able to edit functions at the same time a student is live-editing them. This minor problem only happens during live editing in a connected classroom. [881]
