This paper presents information for educators on delivering an Internet-based course. The paper is divided into three parts. Part 1, "Teaching on the Web, What Is It?," lists advantages and disadvantages of face-to-face classroom instruction, traditional distance education, and Internet-based education which combines features from both these methods. Four proposed models of using the Internet as part of a course (i.e., informational, supplementary, dependent, and fully online) are offered, followed by a discussion of how the Internet can be used to deliver courses, what "added value" means to education via the World Wide Web, accessing course resources on the Web, and forms of interactivity. Part 2, "Training and Skilling Teachers," highlights technology-based skills teachers must develop and lists workshops/tutorials designed to assist teachers with the skills and support needs for developing courses on the Internet. Part 3, "Challenges," proposes several questions that must be addressed when planning/implementing Internet-based instruction. (AEF)
