Describes laboratory activities which relate the mass, volume, density, and radii of atoms through the assumption that the smallest unit of matter is a cubic box containing one atom. From calculations based on macroscopic materials, the author feels that the concept of an atom may be better developed. (CP)

Identifies practices being incorporated in schools under the guise of increasing accountability. (CP)

Many fundamental geometric figures can not be constructed on the familiar square geoboard (e.g., equilateral triangle, regular hexagon). Activities which can be used with an isometric geoboard for study of these figures are catalogued. (SD)

Enrichment topics dealing with solutions of polynomials over modular systems are described. (SD)

Reports on conference of public school and university personnel in which the improvement of preparation of prospective science teachers was the topic. Lists of suggestions are divided into the categories (1) secondary science methods courses, (2) student teaching, and (3) university-public school relationships. (CP)

At the Ohio State University a precalculus course with a very large enrollment was individualized by using a combination of televised lectures, small recitation sections, flexible testing procedures, variable course credit, and other innovative procedures. (SD)

Construction of a laboratory area suitable for laser experiments and the creation of holograms is described. (CP)

After arguing that secondary students are often inept at solving word problems, and that this may be caused by their disinterest in the problems typically presented, the author presents eleven problems she considers to be more relevant to student interests. (SD)

Five puzzles in which mathematical terms must be found in arrays of letters are presented. (SD)

Presents results of a survey given to college students concerning the use of a planetarium in courses and their decisions to take the courses. (CP)

The results of a survey of ten groups of individuals concerned about education are discussed. (SD)

Reports on survey given to 505 elementary students concerning concepts and causes of pollution. Data are reported for each of the eight elementary grades and responses are categorized as being concrete simple, concrete complex, abstract simple or abstract complex. (CP)

Presents a series of activities intended to enable teachers to determine if children are ready to be introduced to the concept of speed. Reviews Piaget's theories and the empirical evidence on which the sequence is based. (Author/CP)
