It is suggested that historical material concerning the model of the earth be utilised in the science classroom to construct narrative explanations. The article includes the various ancient models of the earth, the discovery of the spherical earth model, and the arguments and experiments coupled with it. Its instructional gain may lie in the…

Derives a systematic structure contributing to the solution of the quantum riddle in Einstein's sense by deducing quantum mechanics from the postulates of symmetry, correspondence, and covariance. Indicates that the systematic presentation is in agreement with quantum mechanics established by Schroedinger, Born, and Heisenberg. (CC)

Discusses the impact of science on society from three interpretive bases; the practical applications of science; scientific knowledge and information; and the scientific attitude and approach to phenomena. Suggests that all three bases must be considered or the distortion resulting can have far-reaching effects on man's selection of future…

Investigated was the relationship between proportional thinking and students' ability to demonstrate knowledge and understanding of concepts related to simple machines, structure of matter, and equivalent fractions. The study involved a random sample of 136 ninth-grade physical science students. Each student's proportional reasoning skills were…

THE AREAS OF STUDY ARE--LIVING THINGS, OUR GROWING BODIES, AIR, WATER, AND WEATHER, THE EARTH AND ITS COMPOSITION, THE SOLAR SYSTEM AND BEYOND, AND MATTER AND ENERGY. THOUGH THESE ARE DIVISIONS FOR PURPOSES OF CLARITY, THE TEACHER SHOULD CONTINUALLY POINT OUT HOW THEY OVERLAP. EACH SECTION HAS A SIMILAR FORMAT CONSISTING OF--AN EXPLANATION OF THE…

This language arts learning module offers a structure to teachers for leading junior high school class activities to investigate solar energy, its origin, and effect. The module furnishes a pre-post test, a schedule for library and research work, a basic vocabulary list, and a bibliography. (CP)

This English-French dictionary on solar energy is intended for translators and purports to contain all the elements necessary for doing quality translations. Each entry contains the following elements: (1) the basic English word with its synonyms and equivalents; (2) the definition in English and reference to its source; and (3) sentences or…

THIS STUDY SEEKS TO DISCOVER WHAT CONCEPTIONS OF THE WORLD THE CHILD NATURALLY FORMS AT THE DIFFERENT STAGES OF HIS DEVELOPMENT. TWO DISTINCT STANDPOINTS ARE IDENTIFIED--(1) MODALITY OF CHILD THOUGHT, OR SCHEME OF REALITY, AND (2) THE SIGNIFICANCE OF EXPLANATIONS GIVEN BY THE CHILD. SCHEME OF REALITY REFERS TO THE EXTENT TO WHICH THE CHILD…

The purpose of this study was to investigate the effects of systematic instruction in the concept of speed and simple proportions on the performance of concrete operational children in the third grade. A screening test was administered to select a population of children who could perform simple division and who were concrete operational in the…

This volume provides documentation and selected data for the exercises used by the National Assessment of Educational Progress (NAEP) in nationwide surveys to measure changes in science achievement of young Americans at four age levels: 9-year-olds, 13-year-olds, 17-year-olds, and adults ages 26-35. The exercise documentation includes a copy of…

This report presents data and analyses concerning black participants in two nationwide surveys of science achievement conducted by the National Assessment of Educational Progress (NAEP) during 1969-70 and 1972-73. In both assessments, NAEP selected respondents aged 9, 13, and 17 using a deeply-stratified, multi-stage probability sample. In…

This study is based upon an interpretation of Ausubel's subsumption learning theory. The primary characteristic of this theory is that it views a learner's specific content knowledge as a crucial factor in learning. Two types of assessment instruments were used with first-grade students to determine concept attainment based on specific models…

Reported is a study to evaluate the Science Curriculum Improvement Study (SCIS) program at the fourth-grade level, in particular the unit, "Relativity." To avoid the problems of a written test, an alternative test involving examples of relative position and motion was developed. This 30-item planetarium test was used as a pretest and…
