Integration of the World Wide Web in instruction involves finding and retrieving resources on the Web, communicating, developing teaching and learning activities using the Web, and publishing on it. Related issues and concerns include: (1) finding sufficient time and developing good plans are critical for Web integration; (2) students' involvement is the key to the success of Web implementation; (3) useful Web resources are hard to come by; (4) the Web should not be used solely for disseminating course materials; (5) access to the Web is essential for curriculum integration; (6) schools should create a policy for proper use of the Web; and (7) design a Web page with a good purpose. Suggestions for optimizing the Web for effective instruction include to plan Web-based learning activities ahead of time; relate Web resources with learning contents and develop instructional activities on the Web; watch for proper use of Web resources; conduct formative and summative evaluation on students' performances; encourage communication via collaboration and cooperation; have students keep a log about what they have experienced to increase efficiency and effectiveness for Web exploration; and consider the needs of the audience when organizing and publishing Web pages.
