Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

Several types of physics activities that use real-world problems to motivate learners, use computers to assist in developing conceptual understandings, connect problem situations to mathematical models, and use the models to analyze other real-world problems are presented. The topics of racing sports, sailing, and damped harmonic oscillations are…

Described is a interdisciplinary unit on space. During the planning of their projects, students become immersed in talking about ideas, writing, designing, and illustrating a space colony. The unit relates science to language arts, social studies, mathematics, art, and music. (KR)

Interdisciplinary learning modules called "Maude Visits..." are described. The modules apply basic scientific concepts to current and future problems facing people in various countries such as the Soviet Union. Activities using maps, money, and convection currents are included. (KR)

Presented are 27 science activities for secondary school science instruction. Topic areas include microbiology, botany, biochemistry, genetics, safety, earthquakes, problem solving, electricity, heat, solutions, mechanics, quantum mechanics, flame tests, and molecular structure. (CW)

Presented is a teaching progression that enhances learning through low-cost, manipulative transparencies. Discussed is instruction about restriction enzymes, plasmids, cutting plasmids, plasmid maps, recording data, and mapping restriction sites. Mapping wheels for student use is included. (CW)

Described is Creative Problem Solving (CPS), a model which may be employed to help integrate higher-order thinking skills into elementary science instruction. An example of the use of this model is presented. (CW)

Explained is the effect produced by an optics toy which uses two concave mirrors to produce an illusion. Formulas and calculations used in the explanation are detailed. (CW)

Presents a classroom activity where students vote on topics of interest and then discuss the top ideas through the use of science roundtable discussions. (PR)

Presents a laboratory activity for use during the first or second week of school that engages students in the basic principles of the scientific method. (PR)

Explains how Darwin's observations and experiments can be used to show the true nature of science and good scientific methods. (PR)

Describes experiments by Thomas A. Knight on geotropism. These experiments took place about 200 years ago and used a centrifuge. (PR)

Describes an interview-a-scientist assignment for preservice elementary teachers. Preservice teachers realized that scientists frequently repeat experimental work, that science is not neat and tidy, and that science requires patience and perseverance. (PR)

Presents activities and learning outcomes that came from a project studying the agricultural and architectural technologies of the Hupobi Pueblo who lived in New Mexico some 500 years ago. A large poster with the activities is presented. (PR)

Describes using the aquatic plant, duckweed, for open-ended investigations and learning about factors important in photosynthesis. (PR)
