Today it is possible to link web pages to large databases and manipulate them. The latest browsers from Netscape and Microsoft are capable of placing layers of pages on computer screens with any layer visible according to user input. Codes may be written using languages like JavaScript or VBScript to manipulate these layers for animation and simulation. A very important feature of the Web is its ability to provide access to information that can greatly enhance classroom teaching. Generally, all instructors need a desktop computer with web server software as well as a computer with an Internet browser.
Browsers are either free to download or available at a nominal cost.
The goal is not to replace traditional classroom teaching with instructional material gathered from the Web, but to develop material that can be placed on the Web or departmental network to supplement classroom teaching. First, the Web is available outside the classroom or department even from dormitories or homes. Secondly, Web pages may be linked to other resources on the Internet with the click of a mouse. Finally, Web pages are platform-independent and can be used with any computer with an Internet browser and access to the Internet. With a local network in the department, an Intranet can be set up and instructional materials can be installed on a computer that will serve as a Web server.
