This curriculum supplement was designed to correlate directly with "A Guide to Curriculum Planning in Technology Education," published by the Wisconsin Department of Public Instruction. It is also a companion book to three other classroom activity compilations, one in each of the other three major systems of technology--construction, manufacturing, and transportation. The entire set--the curriculum guide and the four activity books--follows the content organization given in the "Technology Education Content" fold-out chart in this guide. The activities are organized on the basis of how each supports one of the communications concepts identified on the chart. Materials for this supplement were gathered from throughout Wisconsin and several other states, and most of them were developed by teachers. The eight sections of the guide include 24 activities grouped under the following topics: printing systems and processes, photographic systems and processes, graphic industry products, telecommunications systems and processes, computer systems and processes, electronic communications industry products, interactive light systems and processes, and acoustic storage and retrieval systems and processes. Each activity consists of a description, resources needed, objectives, evaluation focus, procedures, information sheets illustrated with line drawings, and (sometimes) tests and answer sheets. (KC)
