This study examined hands-on experiences in the context of an investigation of viruses and explored how and why hands-on experiences may be effective. We sought to understand whether or not touching and manipulating materials and objects could lead to a deeper, more effective type of knowing than that we obtain from sight or sound alone. Four…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

Nationally many middle-level schools are changing from a traditional junior high school structure (grades 7-9) to middle schools (grades 6-8). A case study examined the impact of middle school organizational changes that occurred as a large North Carolina school system converted from junior high schools to middle schools on science teachers and…

This history of the language laboratory and the factors influencing its growth are briefly traced. Materials and equipment are described, and the problems involved in a laboratory operation are indicated. Also considered is the use of the language laboratory as a teaching machine and as a research device for education in general. A bibliography…

Language laboratory practices, as they have developed during the 1960's, are examined with emphasis on the potential improvement of laboratory software. Convinced that weaknesses in the design of materials have led to the misuse and decline of the language laboratory, as well as to student boredom, the author offers alternative approaches in…

PROJECT DESIGN, funded under ESEA Title III, approached the task of establishing learner needs in foreign languages by determining the differences between present student performance and standard or normal development of skills. Information for the study was based on school visits and personal interviews with school administrators and teachers. In…

An experiment, using College Board Achievement Tests in German Reading and Listening Comprehension, to compare the effectiveness of earphones and loudspeakers in language test presentation is described. Related opinions, implications, and conclusions on the effectiveness of communication media in language teaching and testing are offered. (AF)

Describes a first-year chemistry laboratory experiment which uses a simple computer program written in BASIC, to analyze data collected by students about the density of a set of marbles. A listing of the program is provided, along with a sample printout of the experiment's results. (TW)

Discusses the need for mathematics laboratories to supplement classroom instruction in mathematics for engineering students. Provides a description of such a laboratory, including a listing of equipment and materials that are recommended. Describes the uses for personal computers and suggests various problems that could be explored in the…

Laboratory instruction in engineering disciplines in recent years has been adversely affected by a variety of structural problems making it increasingly difficult to provide students with adequate hands-on lab experience on par with the ever expanding requirements of the technical job market. As a possible approach to deal with some of the…

This book is the sixth in a series of publications on the subject of integrated science teaching and is based on the proceedings of a consultation meeting held on the theme "Recent Developments in Integrated Science Teaching Worldwide". The meeting was organized by the Australian National Commission for Unesco, in cooperation with the…

Science projects which can be used by high school students who have minimal experience with computers or electronics are presented in this book on laboratory interfacing. These laboratory interfacing projects include either the connecting of measuring instruments directly to a computer or using a computer to control external devices. All of the 14…

One of the important aims of good biology teaching should be to encourage some basic understanding and appreciation of ecology. This understanding should include not only the scientific basis of ecology, but also its application for human welfare and, in particular, for rational exploitation and management of the natural environment and resources.…

The needs of research universities are discussed in a statement before Congress, with attention to graduate education, young researchers, research instrumentation, and research facilities. The increasing overhead costs associated with doing research are also addressed, along with the appropriate federal role in fostering university/industry…

Designed for individuals wanting to acquire an introductory knowledge of basic skills necessary to function in a water or wastewater laboratory, this handbook emphasizes current use of routine equipment and proper procedures. Explanations and illustrations focus on underlying techniques and principles rather than processes for conducting specific…
