Reported is a research project which investigated whether junior high students in the Ithaca, New York, area can acquire and use the "concept mapping" and "Gowin's 'V' mapping" strategies to facilitate meaningful learning. Concept mapping involves the identification, hierarchical organization, and graphic depiction of…

Several practical methods are presented in this handbook designed to aid the science teacher in the incorporation of reading strategies into the science curriculum. Included are suggestions for assessing the reading levels of science students and textbooks students will be using in the classrooms. Examples and illustrations are provided to clarify…

Reported is an investigation of: (1) the effect of teacher wait-time on science achievement; and (2) the difference in the achievement of children at the formal stage and those at the concrete stage of cognitive development. Teacher wait-time was defined as the length of the pause preceding any teacher utterance. The sample consisted of 23 intact…

Computerized instructional television was used to teach undergraduate students about 100,000 or more extant fungi through an interactive, self testing, teaching program. Students did not find this sophisticated hardware an adequate substitute for the lecture experience and ultimately gave their professor a strong vote of confidence. (Author/JEG)

This is the teacher's guide for the required, interdisciplinary, ninth-year environmental science course for the New York City Schools. One hundred twenty lesson plans, divided into nine units, are presented. Areas of study include the living and non-living environment, ecosystems, population, urban ecology, energy and technology, pollution, and…

This report discusses the current problems in teaching physics to teachers and new techniques for teaching vibrations and waves to students with limited mathematical ability. The author summarizes the topics covered at the Conference within the two categories. (SA)

Described is the kindergarten through eighth-grade science program of the Montgomery County Public Schools, Rockville, Maryland. This program places emphasis on biological science and physical science. Involved are activities selected from several sources, which emphasize the processes of science, the nature of science, and the substance of…

GROWING COLLEGE ENROLLMENTS HAVE BEEN ACCOMPANIED BY SIMILAR INCREASES IN DEMAND FOR GENERAL CHEMISTRY, WITH RESULTANT PROBLEMS OF MAINTAINING QUALITY OF INSTRUCTION. THIS PAPER IS A DISCUSSION OF SOME WAYS OF MEETING THE PROBLEMS OF NUMBERS. MULTISECTION COURSES MAY BE ORGANIZED AROUND COMMON GENERAL OBJECTIVES OR AROUND COMMON CONTENT. AN…

UNIT III (SIX WEEKS) CONCERNS PLANT LIFE, AND DEALS WITH THALLUS PLANTS, MOSSES, FERNS, AND SEED PLANTS. UNIT IV (SIX WEEKS) COVERS AIR AND SPACE, WITH SUBTOPICS ON ASTRONOMY AND WEATHER. "THE CHANGING EARTH," DEALING WITH GEOLOGY AND CONSERVATION, COMPRISES UNIT V (6WEEKS). THE LAST, UNIT VI (6 WEEKS), DEALS WITH CONSUMER…

A STUDY WAS INITIATED IN 12 SECONDARY SCHOOLS TO INVESTIGATE THE EFFECTIVENESS OF FILMED CHEMISTRY AND PHYSICS COURSES. CONTROL VARIABLES WERE USED TO INSURE COMPARABILITY OF EXPERIMENTAL AND CONTROL GROUPS. ACHIEVEMENT, INTEREST, AND ATTITUDE SERVED AS THE STANDARDS BY WHICH THE EFFECTIVENESS OF THE FILMED COURSES WERE JUDGED. BOTH GROUPS WERE…

Presented is a review and synthesis of research in science education conducted with students in grades 6 through 12 during the years 1964-78. In the meta-analysis process, eight constructs linked to learning outcomes were used as the theoretical constructs for the literature selection. The constructs include quality and quantity of instruction;…

Presented are the results of an exploratory study in which methods used in research on teaching were adapted to research on elementary school science teaching. An observation system was designed that enabled an observer to record detailed, context-specific information about the behavior of teachers (N=22) and students in grades 2-5 during…

Appropriate technology is an approach to meeting human needs which stresses local solutions using small-scale decentralized technologies that have minimal environmental impact. Presented in this manual are 10 lessons for upper elementary students that consider such topics as recycling, solar energy, transportation, and nutrition. Each lesson…

This learning module is concerned with the temperature field, the heat transfer rates, and the coolant pressure drop in typical high temperature gas-cooled reactor (HTGR) fuel assemblies. As in all of the modules of this series, emphasis is placed on developing the theory and demonstrating its use with a simplified model. The heart of the module…

This module is part of a series on Physical Processes in Terrestrial and Aquatic Ecosystems. The materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process.…
