Introduces a computer solution of the oscillation of a mass suspended by a spring in a viscous liquid. Describes the equations of motion, spreadsheet solution, copying the formulas, plotting the results, and extending the applications. Presents spreadsheet and physics formulas for the step-by-step solution and spreadsheet solution. (YP)

Introduces one professor's endeavor, "Insect Fear Film Festival," to educate the public about entomology. Discusses some related topics and misconceptions. (YP)

Notes that energy is a difficult concept to learn and provides problems for many students. Stresses that if the science education community were to develop a standard nomenclature of energy-related terms, it would be possible to eliminate some of the difficulties without reducing depth of treatment. (Author/MVL)

Investigates factors associated with endeavors to improve science teaching. Two coaching models used by science educators and by peer teachers were used over a period of six months. Neither program was successful. Five assertions emerged from interviews and observation data. Major impediments were beliefs about teaching and poor science knowledge.…

Assesses the role of science topic instruction combined with logical reasoning strategy instruction in teaching high school students about blood pressure problems. Reports positive effects of the combined instruction compared to science topic instruction. (Author/YP)

Describes a way to help students grasp intermediate steps in the movement and relationships of the various components involved in the addition of an amino acid to a nascent peptide chain. Includes drawings of the model in operation, construction details, and suggested shapes and labeling of components. (RT)

Examines five basic reactions which describe the biochemical pathways for living things obtaining energy. Shows the reactions that occur in respiration after glycolysis, the dehydrogenation reaction, decarboxylation, and two kinds of make-ready reactions which prepare molecules for further dehydrogenation and decarboxylation. Diagrams are…

Discusses the orbit, motion, and phases of the moon. Describes three activities on the moon: "How Soon Can You See a Crescent Moon?"; "When is the Moon Visible?"; and "Lunar Eclipses." (YP)

Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)

Reviews a model used in the teaching of plate tectonics which includes processes and concepts related to: terranes and the amalgamation of terranes, relative plate motion and oblique subduction, the effects of continent-continent collision, changes in plate motion, plate configuration, and the type of plate boundary. Diagrams are included.…

Describes a diagnostic evaluation to measure the idea of the living cell as the basic unit of life. Describes the classification of student knowledge as common knowledge, wide-spread lack of knowledge, inadequate alternatives, and contradictions. (YP)

Answers a student's question about the emission of a positron from a nucleus. Discusses the problem from the aspects of the uncertainty principle, beta decay, the Fermi Theory, and modern physics. (YP)

Describes classroom activities and models for migration, mutation, and isolation; a diffusion model; Bernoulli's principle; sound in a vacuum; time regression mystery of DNA; seating chart lesson plan; algae mystery laboratory; water as mass; science fair; flipped book; making a cloud; wet mount slide; timer adaptation; thread slide model; and…

This article aims to present the results obtained from science teachers about their attitudes toward students' conceptions and the use of teaching strategies based on these conceptions. The results may contribute to the planning of inservice courses. (Author)

Describes how the science fiction novel "Jurassic Park" has been used to provide the focus for summate discussions among gifted high school students participating in a state-sponsored, science-intensive summer program. Discusses adaptations of this approach for use in chemistry classes from the high school to intermediate college level. (JRH)
