This report enumerates the activities of the Educational Technology Center (ETC) during 1987. The guide's theme for the year was Teaching with Technology. The report includes brief descriptions of five different types of research projects by area. In science education, the projects concerned with weight and density, heat and temperature, and the nature of science. Projects in mathematics education included those related to geometry, word problems, and algebra. The research in computing education centered on programming and systems thinking. Research in new technologies centered on computer-based conferencing and videodiscs. And the fifth project area, research in laboratory sites, explored what it takes to carry out ETC-developed innovations in regular schools. Other center activities included agenda building and review, dissemination of the results of center work, and training activities. (PK)
