The article focuses on the effectiveness of selected elementary award-winning materials in the Kazanjian Foundation's Award Program for the Teaching of Economics (KFAP). The mean change Test of Elementary Economics (TEE) scores of the experimental groups using the Kazanjian materials were significantly different from those of the control group. The mean change TEE scores for the classes taught by teachers having in-service training were significantly different from those for the classes taught by teachers without in-service training. The first and most obvious is that it needs to be replicated, in spite of the fact that the study does have important implications both for the organization and teaching of elementary economics. It has shown that the Kazanjian teaching materials can contribute to elementary economics teaching. A major implication is that the Kazanjian Awards Program should continue to encourage the development and use of innovative materials and instructional practices. Finally, the KFAP materials can be adapted and used by other teachers in different school settings.

This article discusses the research on the context of educational media and technology. Instructional design is still an unexplored theoretical and research frontier and at this stage in the history of instructional technology, the function of an educational designer has yet to be clarified, let alone implemented in instructional practice beyond the most rudimentary beginnings. There are no tests or guidelines appropriate for use in designing instructional media-messages nor possess a sufficient body of experimental knowledge which can provide a basis for such design according to the author.

The key to the early warning of a deteriorating clinical situation lies in the change in parameters rather than in their absolute value. This not only colours the choice of sensor, but also affects the design of the discriminators between the sensors and the logic circuits. While the sensors and logic are clearly the most important parts of the equipment, it is probably the presentation of information which will in the end decide the extent to which it is used by nursing staff, and every care must be taken to ensure, not only that false alarms are minimized, but that genuine alarms do not cause unnecessary agitation of the patient.

The article presents information on certain developments related to the field of management science. George Blackett, president of the Institute for Interindustry Data, wrote a special report on the use of input/output models in the United States. The report "Project SOAP: A Systems Approach to Biomedical Research Program Management (A Case Study)" summarizes a case study in the field of management science in which a systems approach resulted in the implementation of a discipline for managing biomedical research programs within a Federal research support agency. The Sixth Annual Simulation Symposium completed three days of proceedings with the presentation of the $500.00 Best Paper Award to Raymond R. McHenry of Calspan Corp. The Ralston Purina Company has recently begun implementation of a new Cathode Ray Tube oriented logistics system at each of its twelve Consumer Products plants. This computer- based operating system was developed by the Operations Research staff of the Company's Consumer Products Division, and is designed to coordinate raw materials.

The article examines the plausible importance of the introduction of moving pictures in city schools in Brooklyn, New York City. The Brooklyn Teachers' Association held an exhibit to test the success of moving pictures in the classrooms. The conclusion of many members of the association was that these pictures could be used with great advantage in the ordinary work of the school. Moving pictures can present instructional materials in geography and other fields of science in a clearer and better way than any other media.
