Explains why the isolated sphere models are physically unsound. Describes an improved model for attempting a qualitative explanation of charge concentration. (YP)

Analyzed are the deficiencies of a traditional freshman course in chemistry, including (1) chemistry model usage, (2) inadequate discrimination between related but different basic concepts, and (3) methods for teaching elementary ideas. Described is an approach used to resolve these problems. (CS)

Presents three reports: a description for an upper-level course in protein chemistry; a technique for generating many unique unknowns for the determination of molecular weight by viscosity; and an analogy for quantization of energy levels in which molecules are considered as books in a library. (CS)

Presents two separate models for implementing a hands-on calculus-based introductory physics course. Included in the discussion are context; purpose; topics; implementation of model one and two; and conclusion. (ZWH)

Describes the Capacitor-Aided System for Teaching and Learning Electricity (CASTLE) project which is a high school electricity curriculum developed by high school and college physics teachers. The project is motivated by research on students' conceptual difficulties in electricity. The instructional materials developed allow students to challenge…

Critiques the Capacitor-Aided System for Teaching and Learning Electricity (CASTLE) curriculum. Criticism is made of the model's use of a compressible-fluid model to demonstrate charge conduction. An alternative model is proposed. (ZWH)

Presents a student centered science curriculum model utilizing inquiry strategy and language rich experiences to develop student skills of questioning, thinking, speaking, listening, and reading. (SL)

Describes a concrete model for teaching the concepts of reflection and refraction without the use of formal mathematics. The model has been tested in five sections of a physics course for nonscience majors at Towson State University, Baltimore, Maryland. (HM)

Investigates the effect of modeling analogy on learning of the concepts of electricity in grade 6, 8, and 10. Describes 2 analogies (train analogy and thermal analogy) with diagrams and examples. Discusses the accessibility, transferability, and difficulty of each analogy. Reports treatment effect and some further implications. (YP)

This article reviews common curricular alternatives for addressing the science education needs of secondary students with learning disabilities. A curriculum revision method emphasizing models and context-rich problem solving is proposed as an alternative to the traditional uses of direct instruction, mnemonics, graphic organizers, and study…

The approach taken to chemical engineering education at New Mexico State University is described in this report. The curriculum model for its undergraduate and graduate program emphasizes both content and skill development. Involvement in tasks related to ongoing research projects is stressed and serves as the basis for course assignments at the…

Suggesting that learning be considered as a generative process, attempts to: (1) place generative learning ideas in the context of other viewpoints of learning; (2) explicate key postulates of the generative learning model; and (3) examine implications of these theoretical ideas for teaching, learning, curriculum development, and research. (JN)

This booklet contains information and activities on the life cycle of stars. Materials can be adapted for grade 9 through grade 12 classrooms. Background information about star birth and life, black dwarfs, supernovae, white dwarfs, neutron stars, black holes, and the electromagnetic spectrum is included. The seven activities focus on star mass,…

This paper introduces a series on the topic and presents a science education framework for teaching students with disabilities. Curriculum and instructional perspectives are reviewed, and the "guided meaning" approach is recommended as an inquiry-based strategy. A thematic scheme for organizing and developing science programs is proposed.…

Uses examples related to a head of cabbage to discuss: (1) sensory development in children; (2) the integration of sensory and cognitive involvement; and (3) a child's mode of exploring and discovering. Also discusses why science curricula need to be organized around a paradigm that is holistic. (JN)
