The CLASS (Communication, Learning, and Assessment in a Student-centered System) Project is creating a complete, accredited, high school sequence for delivery on the World Wide Web. The Department of Distance Education of the University of Nebraska-Lincoln (UNL) is a recipient of $18 million in federal funding to develop the sequence. When completed in 2001, CLASS will offer students 54 courses from which to choose to complete these requirements. The CLASS instructional design model enables input from a variety of sources and empowers the designers with constant feedback. The model includes the following steps: identify the need; assemble the content development team; research; brainstorm; assign personnel; ascertain resources; create a proposal; create the course; and test the course. CLASS instructional features give distance education students the opportunity to learn using a myriad of learning tools that are unique to Web-based distance education, including student-to-student communication, dynamic learning activities, student-selected learning paths, multimedia-reinforced learning, self-monitoring of progress, and the ability to create multimedia portfolios, all in a seamless learning environment not bound by time or space.
