The purpose of this study was to identify: (1) the types of accidents and the areas in which they occur in the high school biology, chemistry, and physics laboratory; (2) the contributing factors that cause accidents; and (3) the preventive measures practiced, and the success of the preventive measures. Four hundred and thirty science teachers…

A study was devised to develop a method for describing a continuous, complex perceptual-motor task in descrete categories by which subjects could be pretrained through the use of static, programed, audiovisual techniques; to construct an audiovisual training device to provide realistic, programed practice in the stimulus-response events selected…

Data collection and analysis as a cybernetic aspect of a Learning Assistance Center (LAC) is discussed. Using the LAC at California State University Long Beach (CSULB) as a model, the LAC is defined as a support, delivery, and referral service for the entire campus community. A LAC is held accountable to itself and its users through a cybernetics…

An innovative and effective laboratory experiment of chemical reference literature is reported. The objectives of the experiment are to acquaint the first term student of college chemistry with the vast source of chemical literature that is available to him; to raise the general level of scientific literacy of these first term college students;…

Included are instructional materials designed for use with disadvantaged students who have a limited reading ability and poor command of English. The guide is the first volume of a two volume, one year program in life science and contains these three units and activities: Measurement, 7 activities; Ecology, 12 activities; and Energy Processes, 24…

Included are instructional materials designed for use with disadvantaged students who have a limited reading ability and poor command of English. The guide is the second volume of a two volume, one year program in life science and contains these two units and activities: Reproduction and Development, 21 activities; and Genetics, 10 activities. A…

The Learning Research and Development Center Time-Sharing System (LRDC/TSS) supports numerous non-standard devices and terminals and provides a variety of powerful programing options, enabling the researcher to maintain close control over the experimental environment. To achieve this degree of flexibility, it was necessary to write programs…

The indroduction of on-line data collection and data processing techniques into an intermediate physics laboratory is described. Using a minimum configuration PDP-8L and a Digital Equipment AD01 analog to digital converter, an interface is developed with two existing experiments. These are a microwave apparatus used to simulate Bragg diffraction…

Students in an introductory biology course had laboratory sessions in one of two patterns: as one three-hour session per week, or as two one-and-one-half hour sessions, one after each lecture. Each of the twelve instructors involved taught one section using each pattern. The Nelson Biology Test, the Watson-Glaser Critical Thinking Appraisal, and a…

A group of introductory college biology students using microscopic slides was compared to another group viewing photographic transparencies in addition to the microscopic slides. Students taught without the supplementary aids performed significantly better on examination questions dealing with the laboratory portion of the course. This unexpected…

The Australian Science Education Project is producing materials designed for use in grades 7-10 of Australian schools. This is the first trial version of a unit investigating microbial action. One of the student booklets contains instructions for the activities demonstrating food decay which all students are expected to complete. The other student…

The Australian Science Education Project is producing material designed for use in grades 7-10 of Australian schools. This is the first trial version of a unit providing instruction in microscopy. Illustrations of each step in setting up, focusing, preparation of mounts, microscopic measurement, and cleaning and packing the microscope are included…

This manual was prepared for the purpose of stimulating the development of effective unit operations and unit processes laboratory courses in environmental engineering. Laboratory activities emphasizing physical operations, biological, and chemical processes are designed for various educational and equipment levels. An introductory section reviews…

This competency-based teacher education program is oriented toward preparing teachers for urban schools. Assuming that student teachers must be knowledgeable about current socioeconomic factors in their working environment, this program aims at developing these competencies using learning modules, learning teams, and teacher education centers. The…

The Elementary Teacher Education Project in Compensatory Education was instituted in 1967-68 at San Fernando Valley State College for the purpose of preparing teachers to work effectively with the disadvantaged at the elementary school level. Main features of the program included student teaching and intern teaching in disadvantaged urban areas;…
