This article discusses preschool education and the research conducted in that field on various relevant topics in an effort to establish recommendations and programs. Cognitive development is the main issue and is seen as a product of maturation as well as of a broad base of experience which results from interaction between the mind and the…

Differences in levels of subject matter learning at the university level were explored to determine how a learning task is approached between those who are successful and those who are less successful. Students read a selected social science text, (Paul Samuelson's "Economics", for example), related the material learned, answered content…

The review of the empirical literature on simulation gaming categorizes positive, negative, and contradictory aspects of gaming as an educational tool as revealed by the research. The review, which concentrates on simulation games for elementary and secondary school students, is presented in seven sections. Section I presents a brief history of…

Describes two approaches of assuring adequate student laboratory preparation by means of computerized, prelab quizzes. One, designed for the Apple microcomputer for introductory chemistry, is available on diskette from the authors. The other, for organic chemistry, is done on a time-shared system. Additional information on this program is…

Describes activities, demonstrations, and materials suitable for middle school science, including investigations on solar energy, surface tension, exploding cottages, worms and light, airplanes, depolarizing simple cells, and the thermal expansion of metals. (JN)

Describes study conducted at the University Sains Malaysia with pharmacy students that compared a videotaped demonstration with a conventional laboratory experiment in physiology to determine the short-term and long-term effectiveness of the instructional media. Treatment for the experimental and control groups are described, and results are…

Describes a first-year laboratory course designed to fulfill laboratory objectives of reinforcing lecture material, teaching experimental methodology, developing hands-on skills, and imparting a sense of error. The course's six segments examine: digital electronics with students building a photogate timer; error analysis; linear accelerated…

Presents a unit of three lessons to teach Newton's Laws of Motion. After rotating through learning centers, answering questions, and recording observations, students are asked to generate a "class law" that explains the scientific phenomenon they observed. (MDH)

The Don River watershed is located within Canada's most highly urbanized area--metropolitan Toronto. Many residential and commercial uses, including alterations to the river's course with bridges, have had a significant impact on the Don's fauna and flora. Pollutants have degraded the river's water quality, a situation exacerbated by the…

The research reported here focuses on links between teachers' comprehension of the underlying physics and their development of educational strategies for classroom work during in-service training. It deals with the teaching of hydrostatics, a topic considered particularly interesting by teachers. Starting from the analysis of simple experiments…

This book brings together leading experts to offer an in-depth examination of how computer technology can play an invaluable part in educational efforts through its unique capacities to support the development of students' understanding of difficult concepts. Focusing on three broad themes-the nature of understanding, the potential of technology…

For several years at the Rural and Small Schools Conference, a special effort has been made to address the needs that are unique to rural science educators. This publication is a compilation of materials presented at those conferences reflecting the following themes: "In Search of Excellence" (1985); "Rural Education: A Proud…

To provide practice in making design decisions, collecting and analyzing data, and writing and documenting results, a professor of statistics has his graduate students in statistics and research methodology classes design and perform an experiment on the effects of fertilizers on the growth of radishes. This project has been required of students…

This packet contains four science learning activities on the subject of animal science that can be used in agricultural education courses. The activities cover these topics: (1) identifying internal parasites in domestic livestock; (2) the effect of feed preparation on feed palatability and consumption; (3) determining the absorption abilities of…

The curriculum materials contained in this document were developed through a cooperative effort by educators in the state of Maryland. It was a curriculum project aimed at the meaningful integration of mathematics and science. It is suggested that these materials be used in two significant ways. First, this document can serve as an instructional…
