In contrast to many hypermediated texts that are poorly designed and are not geared to specific instructional needs, this paper describes the use of “Plato’s Apology: A Hypermediated Learning Environment” (HMLE), an instructional tool capable of meeting the challenge of building an instructionally sound environment for philosophy courses. In addition to providing a description of the interface, the underlying theory-based design principles used to create this HMLE are described, feedback concerning its first two implementations is discussed, and further implications for (...) its use in learning, assessment, and teaching are considered.
