Featuring an increased emphasis on the way today's changing science and technology is shaping our culture, this Second Edition of "Teaching Science in Elementary and Middle School" provides pre- and in-service teachers with an introduction to basic science concepts and methods of science instruction, as well as practical strategies for the…

The author has rewritten rules for CIPW norm calculation and has written FORTRAN IV programs to assist the student in this procedure. Includes a set of problems utilizing the CIPW norm to illustrate principles of chemical petrology. (MA)

The material presented in this three-volume manual is a summary of the history and experiences of the Huntington Computer Project, and the purpose of the manual is to assist high school teachers and other educators who wish to explore the uses of computers in high schools. The first volume contains an introductory section which gives the…

Describes a computer simulation of reaction kinetics in atmospheric photochemistry. (SL)

Computer programs which teach concepts and processes related to biology, earth science, and chemistry are presented. The seven biology problems deal with aspects of genetics, evolution and natural selection, gametogenesis, enzymes, photosynthesis, and the transport of material across a membrane. Four earth science problems concern climates, the…

PRESENTED IS AN EXPLANATION OF WHY CURRICULUM REVISION IN THE SCIENCES IS NECESSARY AND CHANGES THAT HAVE RESULTED IN BIOLOGY, CHEMISTRY, PHYSICS, AND EARTH SCIENCE EDUCATION. ALSO DISCUSSED ARE CHANGES IN TEACHER EDUCATION. SEVERAL PERTINENT QUESTIONS ABOUT THE NEW SCIENCE PROGRAMS ARE RAISED. SOME OF THE TOPICS DISCUSSED ARE--(1) THE BASES FOR…

Contains evaluations of two computer software packages, "Simulation Experiments 45-48 in Epstein's Laboratory Manual for Chemistry" and "Maps and Legends--the Cartographer (Ver 3.0)." Includes a brief description, applications, and the perceived strengths and weaknesses for each package. (CW)

Because density is unobservable and must be inferred from knowledge about weight and size, it is a difficult concept to teach and learn. Even after traditional instruction, many students still have an undifferentiated concept that mixes characteristics of both weight and density. In this study, researchers tested the effectiveness of a unit they…

Two classroom studies, one conducted in the spring of 1985 and the second in the spring of 1986, showed that many high school students do not differentiate between heat and temperature; instead, they have a single concept that contains some of the features of heat and some of the features of temperature. Because the distinction between these two…

The concept of the density of a material has an important role in elementary and secondary school science curricula, but it is a difficult concept to grasp. This project explores why this should be and whether there are some simpler, more accessible notions which can serve as the basis for building a concept of density in students' minds during…

Density is the first intensive physical quantity students encounter that can be understood in terms of an underlying model, the particulate theory of matter. Learning about density provides students with explanations for a range of phenomena such as sinking and floating, and changes of state. Teachers report, however, that density is a difficult…

As a result of declining scores, the National Science Foundation has funded numerous materials-development grants. Largest among these is the Interactive Media Science (IMS) Project at Florida State University (FSU) in Tallahassee. This project's mandate is to design, develop, and produce six level III interactive videodisc programs for middle…
