Government initiatives for incorporating microcomputers in the schools in England, Wales, and Northern Ireland as well as the availability of and attitudes toward computer assisted learning (CAL) in secondary school geography, economics, and history are discussed. In 1980, the government launched the Microelectronics Education Programme to support curriculum development, teacher training, and resource organization. The program has set up 14 regional information centers where inservice training is conducted and has financially supported various agencies to engage in software development. By the end of 1983, every secondary school in England will have a microcomputer. In history, economics, and geography instruction, CAL consists of information handling; statistical analysis; simulation; reinforcement of knowledge, skills, and ideas; production of teaching materials; and management of resources and learning. Of the three subjects, geography has sustained CAL developments on the widest scale. Many history teachers regard CAL as no more than a gimmick. In economics, much software has been promised, but little produced. Most teachers have decided against using CAL since there is not enough hardware or software available. Teacher awareness and knowledge is limited, and sparse research suggests that less able students may have negative attitudes toward CAL. Thus, inservice training is critical to the success of CAL.
