Reeves . The University of Georgia February 12 1998 Executive Summary Introduction There are two major approaches to using media and technology in schools. First students can learn from media and technology and second they can learn with media and technology. Learning from media and technology is often referred to in terms such as instructional television computer-based instruction or integrated learning systems. Learning with technology is referred to in terms such as cognitive tools and constructivist learning environments. Regardless of the approach media and technology have been introduced into schools because it is believed that they can have positive effects on teaching and learning. The purpose of this report is to summarize the evidence for the effectiveness and impact of media and technology in K-12 schools around the world. A limitation of this report is that the vast majority of the published research on the effectiveness of media and technology in schools was conducted in English-speaking countries such as Australia Canada the United Kingdom and the United States of America. For the purposes of this report media is defined as all means of communication whatever its format. In this sense media include symbol systems as diverse as print graphics animation audio and motion pictures.
