The debate on the educational value of dissection versus the value of animal life is examined. Interactive videodisc (IVD) technology is described in light of its potential for laboratory simulations. The design of the IVD-based dissection simulation, The Interactive Frog Dissection, is presented. (KR)

An activity that introduces students to the concepts of independent assortment of alleles during meiosis and gametogenesis, the richness of the variation that occurs as a result of allele recombination, and the unique phenotypes of offspring. Reproducible handouts with the directions and model chromosomes are provided. (KR)

The preparation and format of debates that deal with environmental issues are presented. The educational pros and cons of such debates are discussed. A list of 30 suggested environmental debate topics and a reproducible debate evaluation form are provided. (KR)

Describes an activity in which students receive individual questions (i.e., What is a sparkler made of and what makes it sparkle?) to answers from their "Aunt Gladys." Students must research the everyday question, discover the answer, and then translate the answer into the common language of the masses. (PR)

Sections in this article discuss (1) Science Literacy Needs; (2) Science Education Goals; (3) National Science Teachers Association; (4) Science, Sequence, and Coordination of Secondary School Science (SS&C); (5) Philosophy of SS&C; (6) Geosciences and SS&C; and (7) Geoscience Organization Contributions. (PR)

Described is a program in which students learn about spectroscopy and instrumentation to solve a chemical forensic mystery. Infrared and nuclear magnetic resonance (NMR) spectroscopy, refractometry, and chromatographic techniques were used. An example of a mystery case is included. (KR)

A training program that allows scientists and educators to experiment with new ways to improve student performance in science and mathematics is described. Scientists and educators are encouraged to work together to develop projects for in-service education and projects that can be worked on by students in the laboratory. (KR)

The situation regarding each Australian State's secondary physics syllabi are summarized. The planning directions necessary to keep such syllabi relevant to the changing needs of Australian secondary students are discussed. Factors influencing the implementation of these physics courses are described. (KR)

Discussed is how modern physics is usually approached via the photoelectric effect and how this can lead to a physically wrong picture of light. The importance of using the quantum theory developed after 1920 to explain the properties of light is discussed. (KR)

Listed are 75 computer software programs which are available for use in teaching physiology at the high school and college level. Included is a brief description of each and an address for obtaining additional information. (CW)

Presented are the findings of a naturalistic case study of science teacher thinking. The role of personal practical theories and curricular and instructional decisions is discussed. Suggested implications of understanding personal theorizing of science teachers and science teacher educators are included. (KR)

Investigated were the determinants of intentions to enroll in a high school science course by middle school earth science students. The impact on intentions of students' attitudes, social pressures, and specific external variables are discussed. (KR)

Investigated were determinants of teachers' behavioral intentions including attitude toward the behavior, subjective norm, and perceived behavioral control. Intent to perform the behavior appears to be under the control of most teachers, with little need for social support and with ample resources and sufficient opportunities available to perform…

A phenomenological explanation of this effect is provided. Suggestions for the inclusion of pyroelectric effects into a unit on electrostatics are given. (CW)

Detailed are the construction of a demonstration car, apparatus and procedures used in the demonstration, and the analysis of the effects of car braking. The cases of rear-wheel and front-wheel braking are considered. (CW)
