About 100 years ago, steam and water power provided less than one-quarter of the energy needed for all production. Men and animals provided the rest. Today in the United States machines supply 98 percent of all power for industrial work. The technological change that has taken place in this time has been phenomenal and, undoubtedly, will be even more rapid in the future. Industrial arts deals with the technology--its tools, materials, machines, industrial processes, and its related human problems. This study provides a detailed analysis of instructional content in State curriculum guides for selected subject areas of the industrial arts in the United States. The information derived from this study provides persons engaged in the improvement of instruction in the industrial arts at the State and local levels with basic data bearing on the nature, scope, and sequence of the industrial arts curriculum area in the public schools of the United States. A bibliography is included. (Contains 8 figures, 3 tables and 14 footnotes.) [Best copy available has been provided.]
