Hayward, Elizabeth O. – Cultural Studies of Science Education, 2012
In this paper I explore how Margaret Beier, Lesley Miller, and Shu Wang make claims for the validity and reliability of the instrument they developed to explore the construct of "possible selves" as described in their manuscript, "Science Games and the Development of Scientific Possible Selves."
Descriptors: Self Concept Measures, Measurement Techniques, Test Construction, Test Validity

Renner, Michael J. – Journal of Research in Science Teaching, 1979
Explains that Rogers' proposed sequence of development in proportional reasoning is not really a modification of Inhelder and Piaget's task, but could be considered as a new task. Rogers acknowledged the explanation as a valid one. (GA)
Descriptors: Affective Behavior, Cognitive Processes, Instrumentation, Logical Thinking

Lucas, A. M. – Science Education, 1975
Discusses reasons for questioning the underlying assumptions of instruments designed to measure knowledge of the nature of science. Recommends that researchers recognize that conflicting models of science exist, and that each instrument related to these models must specify all philosophic assumptions. (MLH)
Descriptors: Educational Research, Instrumentation, Measurement, Measurement Techniques

Ewing, Galen W., Ed. – Journal of Chemical Education, 1974
Descriptors: Chemistry, College Science, Electronic Equipment, Instrumentation

Blade, Richard A. – American Journal of Physics, 1978
Describes the design of a sequential switcher to be used for multichannel strip-chart recordings of temperatures at different points in a solar heated building. (GA)
Descriptors: Electric Circuits, Electronics, Equipment, Heat

Grauer, Albert D. – American Journal of Physics, 1974
Discusses instrumentation and describes such research areas as the albedos of the brighter planets, rotation rates and atmospheres of the larger and brighter satellites, brightness changes of outer planets, asteroid rotation rates, and variable stars. (GS)
Descriptors: Astronomy, College Science, Electronic Equipment, Instrumentation

Daines, Terri L.; Morse, Karen W. – Journal of Chemical Education, 1974
Descriptors: Chemistry, College Science, Instructional Materials, Instrumentation

Miguel, Antonio H.; Braun, Robert D. – Journal of Chemical Education, 1974
Descriptors: Chemistry, College Science, Environmental Education, Instructional Materials

Ewing, Galen W., Ed. – Journal of Chemical Education, 1975
Identifies a trend in analytical chemistry toward greater use of instruments and a need for an understanding of the basic principles involved in instrumentation. This need can be fulfilled using homebuilt equipment; examples are provided in the areas of electrolytic conductance and electronic coulometry. (GS)
Descriptors: Chemical Analysis, Chemistry, College Science, Electronic Equipment

Jeffreys, J. A. D. – Journal of Chemical Education, 1979
Presented are lists of deshielding constants chosen to be easy to remember and to given estimates close enough to measured shifts to allow interpretation of the spectrum of a compound of known structure. (BT)

Descriptors: Chemistry, College Science, Electronic Equipment, Instructional Materials

Long, Robert, II – American Journal of Physics, 1975
Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)
Descriptors: College Science, Higher Education, Instruction, Instrumentation

Panijpan, Bhinyo – Journal of Chemical Education, 1979
Spectroscopic studies on solutions and x-ray diffraction work on crystals lead to the conclusion that the Metrogen of the pyrimidine ring is preferentially protonated. The correct monoprotonated structures of thiamine and its 4-amino-pyrimidine synthetic precursor are presented. (BT)
Descriptors: Biochemistry, Chemical Analysis, Chemical Nomenclature, Chemistry

Rubba, Peter A.; Andersen, Hans O. – Science Education, 1978
Discusses the development, field testing, and validation of an instrument designed to assess secondary school students' understanding of the nature of scientific knowledge. (GA)
