Describes the process of acquiring a computer-assisted instruction system by the Linton-Stockton School Corporation (LSSC). Discusses problems that made the acquisition difficult. Presents the results of a standardized achievement test given to students before and after experience with the system. Emphasizes gains in reading comprehension. (CW)

Lists five experiments or demonstrations involving hypodermic syringes. The titles of experiments are Boyle's Law, Charles' Law, Atmospheric Pressure, Expansion of Gases, and Boiling at Reduced Pressure. Provides a list of materials, the typical data, and graphs where appropriate. (YP)

Argues that the recent "crisis" in science education was unfounded. Claims that the reduction in federal funding through the National Science Foundation in 1981 was the real problem that precipitated the concerns about scientific literacy. (TW)

Discusses some of the improvements made recently in computerized speech and some questions about using such technology in classrooms. Describes the hardware needed for speech software. Provides a directory of what is currently available in speech-based products. (TW)

Suggests that elementary school students should be introduced to science research by involving them in group projects. Argues that this type of collaborative approach is more motivating for the students, and produces less anxiety and a better understanding of the steps involved in scientific methodology. (TW)

Reports on a study designed to examine selected units of commonly used elementary science texts, using the Project Synthesis goal clusters as a framework for part of the examination. The discussion of the finding focuses on the comparison of the results to recommendations of the National Science Teachers Association (NSTA). (TW)

Reports on a study intended to determine the science education research interests of elementary teachers and to examine the data according to certain demographic variables. Results indicate that hands-on experience, science content, cognitive development and learning styles, problem solving, and teaching strategies were the top five research…

Reports on a study conducted in the Richardson Independent School District (Texas) which was designed to assess the attitudes toward science of students and teachers who have been involved with the Science Curriculum Improvement Study (SCIS) compared to non-SCIS students and teachers. (TW)

Uses a demonstration done by John Tyndall in 1856 to show that geological processes can produce striking changes, such as slate formation, by slow and incremental means. Explains how Tyndall's demonstration can be replicated in the classroom using paraffin or beeswax to produce the layering change similar to slate. (CW)

Describes the flour beetle, "Tribolium confusum," and its life cycle, habitat, culturing requirements, and some possible uses of this beetle as a classroom animal. Discusses what children could learn from flour beetles. Explains how to get rid of beetles found in foods at home. (CW)

Discusses the causes, sources, and problems associated with acid deposition in the Pacific Northwest. Includes a learning activity about acid rain, "Deadly Skies," which was adapted from the Project WILD Aquatic Supplement. (TW)

Provides information about saltwater wetlands. Contains seven learning activities which deal with "making" a mud snail, plants and animals of mangroves, and the effects of tides on salt marshes. Included are reproducible handouts and worksheets for several of the activities. (TW)

Suggests practical activities which can be introduced into the training of Swedish nursery school and compulsory school teachers for the purpose of improving the organization of technology classes. Explains how simple inexpensive materials can be used in imaginative ways to intrigue and involve children, especially girls, in technical activities.…

Concept maps and structured/clinical interviews were completed by 25 fourth graders and 25 college freshmen to determine knowledge of the human circulatory system. Students (N=945) at various levels were then measured for misconception frequencies. Student preconceptions appear to be tenacious, but confrontation strategies may assist fundamental…

Develops and explains a format for a workshop which focuses on soap films and bubbles. The plan consists of: a discussion to uncover what children know about bubbles; explanations of the demonstration equipment; the presentation itself; the assembly of the workshop kit; and time to play with the bubbles.
