Reaching Beyond the Invisible Barriers: Serving a Community of Users with Multiple Needs

摘要

This paper discusses a four-phase model for evaluating multi-media learning materials that emphasizes the diversity of learners and variations in instructional needs and user characteristics. The authors begin with an overview of the model, supporting evidence for its use, and key characteristics of users supported by each of the phases. They then focus on results of a current use that emphasized stage four, real-time usability, and show how they were able to document that the models under review met the needs of diverse learners and varied instructional strategies.
