This document presents a model for a simple transmission electron microscope for educational purposes. This microscope could demonstrate thermonic emission, particle acceleration, electron deflection, and flourescence. It is designed to be used in high school science courses, particularly physics, taking into account the size, weight, complexity…

Based on experiences gained through involvement with three curriculum development projects, one relating to an elementary science curriculum and the other two relating to junior high school mathematics, the following recommendations are presented: (1) financial support from an outside agency, public or private, makes boldness more probable in…

This address presents the results of a nationwide survey of science educators throughout Australia, including teachers, curriculum workers, and teacher educators. These educators were asked to comment on three categories related to science education: (1) past trends, (2) aims, and (3) future trends. Results of the past trends questions indicate a…

This syllabus presents material to be covered in chemistry for pupils of varying skills and abilities in New York public high schools. An outline of topics provides an overview of the principles, concepts, and applications included within the course and tested in the New York State Regents Examination. Twelve units of study are described. Material…

Described is the ninth- through twelfth-grade science program of the Montgomery County Public Schools, Rockville, Maryland. This program provides opportunities for students to experience individual interests and career choices. Two credits in science are taken in grades nine through twelve and generally include laboratory science and biology. Most…

A YEAR COURSE IN NINTH-GRADE SCIENCE WAS IMPROVED BY THE EVALUATION OF EACH LESSON USING A LEARNING PROFILE STUDENT RATING TECHNIQUE.THE PURPOSES OF THE STUDY WERE TO MAXIMIZE EFFICIENCY OF SCIENCE INSTRUCTION, TO MEASURE IMPROVEMENTS, TO TEST EFFECTIVENESS OF NEW MATERIALS, TO SUGGEST WAYS OF IMPROVING INSTRUCTION, TO EVALUATE ACTIVITIES ON A…

THE PURPOSE OF THE STUDY WAS TO DETERMINE THE RELATIONSHIP BETWEEN STUDENTS' ACHIEVEMENT ON BEGINNING CHEMISTRY AND THEIR BACKGROUND PRIOR TO ENROLLMENT IN THE COURSE. OF THE 609 STUDENTS ENROLLED IN BEGINNING CHEMISTRY IN THE 1964-65 ACADEMIC YEAR, 45 PERCENT RECEIVED GRADES OF A, B, OR C. OF THE GROUP STUDIED, 23 PERCENT WERE REPEATING THE…

This teacher's guide suggests a number of ways to use a spinning table to explore circular motion. Activities are described which are appropriate for children in kindergarten through third grade. Suggestions are made for exploratory activities using the equipment rather than supplying detailed instructions for formal activities. Equipment and…

Presented are building activities, for elementary school children, using a variety of different materials. Weak materials, such as clay, straws and pins, paper tubes and index cards, are used as examples; structures built with these materials are displayed in photographs and discussed. Problems are suggested from which additional activities can be…

Presented is a two-year associate degree curriculum for Engineering Technology. Specializations are provided in civil, electronics, and mechanical technology. The civil engineering technology specialization facilitates three major areas of study, and mechanical technology includes design and production options. Each curriculum was designed to…

This guide provides the assessment procedures for use with the seven science units of the grade 6 Conceptually Oriented Program in Elementary Science (COPES) science curriculum program. Included are individual screening assessments for each of the seven grade 6 science units, instructions for using the guide, instructions for scoring the…

The resource guide integrates learning activities in biological science with an exploration of careers in biology or related fields. The materials are divided into seven units: tools of the scientist, basis for life, diversity (protists, plants, animals), structure and function, continuity (reproduction, development, and genetics), evolution, and…

This study, conducted at Northeast Catholic High School for Boys in Philadelphia, was designed to determine if a significant difference existed between ninth-grade students experienced in Introductory Physical Science and ninth-grade students experienced in conventional General Science in ability to manipulate basic physics laboratory equipment,…

Two problems were considered in this study: (1) to determine if there were combinations of variables in the population studied that were predictive of science-teaching practices and/or teacher satisfaction with teaching science; and (2) to determine if models could be developed to explain possible directional effects of selected teacher variables…

The effects of a series of science lessons on reading readiness were investigated. Kindergarten children from three schools in central-city Milwaukee were the subjects. Twenty children from the University of Wisconsin-Milwaukee Laboratory School were used to try out the procedures and materials used in the prepared science lessons. Twenty children…
