Mission Statement: This volume will highlight papers presented at the second Nebraska Symposium on Information Technology in Education. With chapters focusing on the latest research findings and theoretical principles for using technology in education, the volume will extend findings from current research on technology-mediated instruction into a set of practical principles for designers, teachers, and managers of educational technology. Contributors will identify technical and design features required for sharing of content and assessment tools and will target promising areas for future research and development in technology-based learning, instruction and assessment.
