An engineering case study is used as the focal point of a communications course. Communications theory and practical exercises are structured around the case study described, an adaptation and extension of the power station game developed in the early 1970s. Includes outline of and sample student activities. (JN)

To provide an activity illustrating why they encounter conceptual difficulties in physics, students constructed a "world map" of physics which defines various "seas" and illustrates relationships between them. Salient features of this approach and physics concepts fostered are included. (JN)

Procedures for constructing an inexpensive, hands-on working model of DNA are provided, as well as suggestions for using the model in a high school or college biology class. (DC)

Some contentions of scientific creationism that conflict with accepted principles of geology (catastrophism, fossil records, earth's age, rock formation, second law of thermodynamics) are reviewed, demonstrating that these claims are based not on scientific research or reasonable conjecture but on Biblical references. (Author/DC)

It is suggested that gifted children need opportunities to interact with each other, opportunities for discovery learning, programs which will foster independence, and programs which will include activities in all three learning domains. The teacher's role is defined, and examples of activities suitable for gifted instruction are provided. (MP)

Procedures used by a primary science class to build five different working solar furnaces are summarized. Diagrams, illustrations, and graphs of children's results are included. (DC)

Laboratory procedures, equipment, teaching ideas, and resource materials related to physics are discussed. Topics include the construction of a liquid-metal pump, a hydraulic jack, and an apparatus which helps teach time/velocity graphs; current/voltage characteristics of a tungsten filament lamp; and an electric circuit game. (DC)

Introduces a teaching method called guided design which involves a series of problems and solutions with feedback that leads students in a logical sequence through material being taught. Presents 15 worksheets to demonstrate the use of this technique in an introductory ornithology course. (Author/DC)

Nine computer programs (available from the authors) are described including graphic display of molecular structures from crystallographic data, computer assisted instruction (CAI) with MATH subroutine, CAI preparation-for-chemistry course, calculation of statistical thermodynamic properties, qualitative analysis program, automated conductimetric…

Descriptions of high school chemistry courses are provided, including organic chemistry, introductory chemistry for mathematics-shy students, and a course for eighth-graders taught by high school seniors. (SK)

Presents comments from a symposium at which scientists and science educators agreed that science education should focus more on problem solving and less on mastery of content. Also suggests ways to select textbooks that support a problem-solving approach. (DC)

Presents chemistry activities suitable for elementary students. Lists chemicals commonly used in elementary science, their common names, and where they may be obtained. (DS)

Describes a preschool science-based curriculum which encompasses four broad topics: water, small creatures, gadgetry, and environmental terraria. Includes a description and list of activities for each topic. Presents research suggesting that children participating in this curriculum increased their self-directed discovery and verbalized curiosity.…

Describes a study which explored some difficulties related to technical and nontechnical vocabulary and the structure of the examination questions in electrochemistry. Includes results from a sample of 1,500 students in the fourth forms. (DS)

Draws on literature from the fields of science education, anthropology, and other areas. Proposes a viewpoint that science and science education are cultural enterprises which form a part of the wider cultural matrix of society and that educational considerations concerning science must be made in light of this wider perspective.
