Discusses the relation of technology to the green revolution, the role of plant breeders in inducing change in stagnant agriculture and the tools required by production scientists to increase yields of basic food crops in developing countries. (BR)

The study was designed to show the important role of communication in learning. It was postulated that a high-kinetic-structured lesson would facilitate a greater amount of affective learning than would a low-kinetic-structured lesson. The results supported the hypothesis. (BR)

Describes a computer program which can be used to explore the effects of various values of r and C on population growth, using electronic calculators. (BR)

Describes the manpower situation in geoscience and the job opportunities that have opened up in response to the shortage of vital materials and energy sources. (BR)

Reports the 1974 survey of both graduate and undergraduate enrollment in geoscience departments; reports the median salaries for graduates and breaks down the enrollment according to sex and minority groups. Also reports that industry is recruiting BA/BS and MA/MS graduates vigorously but employment of Ph.D.'s is declining. (BR)

Describes the study of electronics as a terminal course in electromagnetism. A lecture-laboratory approach is used with a strong emphasis on practical experience. Outlines the major topics of the lecture program and describes the activities used in the laboratory. (GS)

Identifies problems facing the science educator as a result of the activities of professional educationalists and the knowledge explosion. Presents answers to these problems in an enumeration of the basic ingredients of scientific education, a consideration of the overall curriculum, and a discourse on the art of teaching. (GS)

Sets forth laboratory requirements for space, furniture, services, and special needs. Briefly reviews current laboratory conditions and practices and provides references for further research in this area. (GS)

Describes a simple and inexpensive model to demonstrate the pulsed magnetic resonance phenomenon. Gives the details of construction of the device which can provide a direct demonstration of the precessional motion of a magnetic moment in a steady magnetic field. (Author/GS)

Provides an outline of the topics covered in the program. Included are introductions to transactional analysis and Piaget's theory of intellectual development. Explains the evaluation of the program and presents data obtained from past participants. (GS)

Describes a competency-based instruction (CBI) system in which a student must regularly demonstrate satisfactory understanding or performance of specified competencies in order to proceed to new materials. Reports mastery and timing results suggesting more efficient learning in a CBI system. (Author/GS)
