CONCENTRATED FOREIGN LANGUAGE PROGRAMS HAVE BECOME INSTITUTED IN THE PUBLIC SCHOOLS. REASONS INCLUDE--THE REALIZATION THAT VALUABLE INFORMATION AND KNOWLEDGE HAVE BEEN WRITTEN IN OTHER LANGUAGES, THE U.S.'S PIVOTAL POSITION AS A LEADER IN THE WORLD, AND THE GENUINE INTEREST AND AWARENESS OF THE HIGH SCHOOL STUDENT. THE DEVELOPMENT OF LANGUAGE…

This laboratory unit is designed for a minimum of 15 hours of work. Experiments are designed to fit a complete unit of study on energy, and require only simple, inexpensive, or easily constructed equipment. Motivational questions, objectives, support information, feedback items, and follow-up activities are incorporated into the various…

In selecting clinical facilities for health technology programs, many points must be considered, since competence in this field cannot be achieved without clinical experience. This guide describes (1) the important differences between clinical practice and work-study programs, (2) the selection of off-campus facilities, predicated on a thorough…

An appraisal of the language laboratory attempts to clarify its purpose and its proper use. The first part of the article describes the various advantages of laboratory instruction, stressing the value of individual study and progress and the need for a "live" teacher. Types of equipment in a "Dialog" laboratory are explained and illustrated in…
