Over the years, instruction has shifted from the traditional face-to-face delivery to instruction that is done from a distance. Distance education is instruction that occurs when the instructor and student are separated by distance, time, or both (WCET 2004). Some common technologies used in distance education are videotape, broadcast television, ITFS (instructional television fixed service), satellite, interactive video, audio tapes, audio conferencing, CD-ROM, and computer (WCET 2004). More recently, the computer and Internet have played a large role in distance education through computer-based instruction (CBI) and Web-based (online) courses. These innovations have changed the face of distance education and revolutionized the concepts of teaching and training. In CBI, the computer is the primary medium for instruction and learning; in online instruction, the learning is delivered via the Web and often through a Learning Management System (LMS; Wise 2004). This article looks at particular formats of distance education in high schools and the benefits and challenges of each. It also provides suggestions for teaching online courses.
