A study assessed the competencies developed for the Teaching of Elementary Science course by observing recent graduates of the college as they taught science and by interviewing them concerning their science teaching. An instrument was developed for rating teacher behavior in each competency area. Observations were made by college and school…

Gal'perin's instructional theory of problem solving is described. This theory of stage-by-stage formation of mental actions was chosen as a theoretical basis for the construction and evaluation of courses in higher education, particularly in science and technology. A Programme of Actions and Methods (PAM) for problem solving in science,…

This paper describes a one-semester remedial biology course for freshmen college students. It includes rationale for such a course at the college level, course content and organization, and instructional strategies associated with specific problem areas such as the inability of students to categorize and distinguish between categories. Appendices…

This booklet was written for anyone interested in growing mosquitoes and experimenting with them. There are three major sections: (1) rationale for studying mosquitoes, (2) raising mosquitoes, and (3) some scientific findings. The first section describes basic information about mosquitoes. The second section includes information about materials,…

This teacher's guide on earthworms includes four major sections: (1) introduction, (2) caring for earthworms in the classroom, (3) classroom activities, and (4) the appendix. The introduction includes information concerning grade level, scheduling, materials, obtaining earthworms, field study, classroom clean-up, and records. Caring for earthworms…

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…
