Allow plenty of lead-time for planning the course and designing course web pages.
Be sure that the course web pages are functional.
Have a back-up plan for lectures (e.g., print or save the web pages on your local hard drive).
Be well-prepared for your presentation, for example:
check the classroom set up (e.g., browser, software, computer memory, monitor, and audio).
verify links, especially the external links.
check the room lighting to see if it is suitable for both viewing the projected screen and taking notes.
arrange for a technical support staff to be in your classroom at the start of class to help with the setup if necessary.
always know whom to call for help if technical problems occur.
Emphasize the need for filtering and interpreting information on the Web when encouraging students to use online resources.
Remind students that only a smaller fraction of the whole archive of knowledge is available on the Web.
