This textbook presents scientific knowledge in a question-and-answer format. It is intended for the use of families and schools, explains about 2000 questions that children commonly ask, and is written in language so plain as to be understood by all. Heat, non-metallic elements, metals, organic chemistry, meteorology, optics, and sound are covered.

To discover if narrative analogies of scientific mechanisms would help readers to comprehend passages describing those mechanisms, four such passages were extracted from an encyclopedia. These original passages were written in expository style and constituted the expository condition. For the narrative condition, simple narrative analogies of…

DESCRIPTIONS WERE GIVEN OF TWO OPERATIONAL FRAMEWORKS FOR THE INSTRUCTION OF EDUCATIONALLY DISADVANTAGED, SPANISH-SPEAKING CHILDREN BETWEEN THE AGES OF 6 AND 9 IN THE FIRST AND SECOND GRADES OF AN ENGLISH-SPEAKING, MIDDLE-CLASS, SCHOOL ENVIRONMENT. THESE FRAMEWORKS, DESIGNATED AS "THE SCIENCE-BASED MODEL" AND "THE SELF-CONCEPT…

An appeal for more research to determine how to educate children as effectively as possible is made. Mathematics teachers can readily examine the educational problems of today in their classrooms since learning progress in mathematics can easily be measured and evaluated. Since mathematics teachers have learned to think in quantitative terms and…

This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It is intended for use by college students at the Junior and Senior levels. There are nine chapters in this monograph. The failure of classical theory in dealing with elementary particles physics is…

This study was designed to identify those science concepts and mathematical skills that may be the source of student difficulty in learning chemistry as developed by the Chemical Education Materials Study (CHEMS). The instruments utilized were four Achievement Tests prepared by CHEMS. Each test item was analyzed to determine the concepts and/or…

The purposes of this study were: (1) to formulate a current list of biological principles to use as a checklist in the study; (2) to utilize the checklist in identifying principles required for reading comprehension of news articles concerning the various areas of biology or biology-related social problems; and (3) to survey the Biological…

Content and task dimensions of science items were studied using factor analytic techniques. These items were developed to measure concept attainment using a completely crossed design with 30 concepts and 12 tasks. Conventional factor analyses were performed, separately for boys and girls, for concept scores and for task scores. Three-mode factor…

A comparison was made between the language of a group of articles taken from the "Scientific American" and the language of articles given as references by them. Distribution and overlap of vocabulary in the two groups of articles were analyzed. Some differences between the writings in two areas of science were found. (Author)

Looks at opportunities and needs within the teaching of physics at the secondary level to develop ideas of chance, and to set these within a discussion of some of the problems of what the subject should be like at this level. (Author/GA)

The purpose of this investigation was to test extensions of a model of concept learning. The investigators examined the applicability of a mathematical model to the learning of selected science concepts. Findings suggest that certain extensions of the model may apply for a complex concept identification task. (Author/MA)
