Describes a satisfactory junction that can be easily fabricated. Discusses the specifications and applications of the junction. States that this junction is especially useful for microcells. (CW)

Presents calculations that suggest stoichiometric, ionic, and noble gas-metal compounds may be stable. Bases calculations on estimated values of electron affinity, anionic radius for the noble gases and for the Born exponents of resulting crystals. Suggests the desirability of experiments designed to prepare compounds containing anionic,…

Provides several reasons for the lack of the classroom teacher's involvement in science education research. Explains the purposes, advantages, involvements, and kinds of research. States that without teachers as researchers, there is an inability to put knowledge to practice. (RT)

The purpose of this experiment was to compare an inquiry-oriented Biological Sciences Curriculum Study (BSCS) style laboratory approach with a more directive traditional approach on student outcomes in the cognitive and affective domains of learning at two private, midwestern liberal arts colleges. Intact laboratory sections of students enrolled…

Follows an experimental program where 30 trained high school science teachers used 6 to 10 students each to produce an original experimental environmental research project. Offers suggestions to improve science in high schools. Lists methodology of several of the projects and describes others. (ML)
