This analysis of the relationship between science education and technology over the past 15 years focuses on lessons learned from research on learning and instruction, the relationship between the teacher and technology, and the influence of technological advances on educational practice. Five conclusions are drawn: (1) courseware authoring…

Most children become excited about science because they can do something and because they can watch the results. These are some of the answers most elementary school students tell you when they are asked about science class. It has been substantiated by decades of research that experiential experiences are exciting and remembered, visual and…

In evaluating whether the laboratory guides for Project Physics and for PSSC are consistent with the goals of their designers in demonstrating the interplay between experiment and theory in the development of physics, a system was developed for analyzing physics laboratory investigations, and the laboratory activities in the "PSSC Physics…

THE INFLUENTIAL RELATIONSHIPS BETWEEN THE STUDENT AND HIS TEACHERS AND PEERS WERE INVESTIGATED TO DETERMINE HOW AND WHY THEY MIGHT AFFECT STUDENT DESIRES AND OBJECTIVES. THREE SEPARATE STUDIES WERE CONDUCTED, INVOLVING APPROXIMATELY 740 JUNIOR AND SENIOR HIGH SCHOOL STUDENTS. THE FIRST, A QUESTIONNAIRE STUDY, EXAMINED THE EFFECTIVENESS OF SOCIAL…

THIS STUDY WAS DESIGNED TO TEST THE THEORY THAT LABORATORY GROUPS MAKING COMPLEX DECISIONS WILL DISTORT THEIR PERCEPTIONS OF EACH OTHER IN WAYS PREDICTABLE FROM NEWCOMB'S A-B-X MODEL OF PERCEPTUAL DISTORTION IN WHICH "A" REPRESENTS THE PERCEIVING INDIVIDUAL, "B" REPRESENTS ANOTHER MEMBER OF THE GROUP, AND "X" THE…

Approved by the American Psychological Association (APA), these guidelines are designed to help high school psychology teachers make decisions relating to ethical problems in their classrooms. The guidelines cover three areas: the use of animals in school science behavior projects, the use of human participants in research or demonstrations…

Designed to accompany the student text on respiration, this manual presents instructions on the use of laboratory equipment and presents various experiments dealing with the concepts presented in the text. Thirty-nine laboratory activities are described. Laboratory activities are divided into several parts, each part covering a specific experiment…

The performance of instructor pilots and student pilots was compared in two visual scanning tasks. In the first task both groups were shown slides of T-37 instrument displays in which errors were to be detected. Instructor pilots detected errors faster and with greater accuracy than student pilots, thus providing evidence for the validity of the…

A computer-assisted instruction (CAI) physics lesson on magnetism was supplemented with slides and film loops to provide a simulated encounter with simple magnetism experiments. Two groups of students took the CAI lesson, but one group viewed the simulated experiments, while the other group performed the actual laboratory experiments. Since…

This vocational physics individualized instructional student module on the alternator consists of the four units: Current electricity, magnets from electricity, electricity from magnets, and energy conversion. Designed with a laboratory orientation, the units present explanations of the concepts and experiments. Laboratory data sheets,…

Reviews Apple computer science programs that are useful in a laboratory setting. Includes laboratory simulations, uses of Apple as a functioning lab instrument, and dissection programs. (ML)

Argues that field research can provide evidence about the long-term socialization and developmental effects of media violence on viewer's behavior. Summarizes findings from a number of quasi-experimental studies about the effects of naturally occurring media violence. Concludes that these findings are often consistent with the hypothesis that…

Describes two experiments for demonstrating the properties of osmosis and semipermeable membranes. Gaseous and liquid osmosis are studied through the use of common laboratory chemicals and equipment. Offers explanations for the phenomena with diagrams. (ML)

Reports two methods for interesting children in chemistry. Describes a method for producing large soap bubbles and films for study. Examines the use of simple stories to explain common chemical concepts with example given. Lists titles of available stories. (ML)

Explains that triglycerides consist of a mixture of different compounds, depending on the total number of fatty acid constituents. Details the method and instrumentation necessary for students to analyze a vegetable oil for its triglyceride content. Describes sample results. (CW)
