Platforms, browser compatibility and resolution

The Visualization Environment and concept models run on PCs and UNIX machines. The website requires a JavaScript-enabled browser. The site functions correctly when viewed with Netscape Navigator version 4.0 or Microsoft Internet Explorer version 4.0 or higher. It will probably work on older browsers; you'll have to check to make sure. The site works best at 1024 x 768 screen resolution or higher and with 24-bit color resolution.

If you want to view your webpages at a later time, click on the Learner Guide menu option and select View Your Submissions. A pop-up window will appear with a list of the activities that you've submitted so far, from which you'll be able to select the ones you want to view.

Note that the online submission system is password protected. You will be asked to select a password when you first access the system. An email will be sent to you with the password; be sure to keep it for future reference. If you ever need to request your password, send us email.
