Stepans, Joseph; Olson, Melfried – School Science and Mathematics, 1985

Suggests activities which provide students with opportunities to give meanings to symbols and to find reasons for doing computations. Includes investigations with a pendulum, circular running track, salary increases, and container volume. Indicates that teachers should place less emphasis on drill and manipulation to give meaning to abstract…

James, Robert K.; Crawley, Frank E. – School Science and Mathematics, 1985

Defies the assumption that laboratory teaching skills are gained by preservice secondary science education majors through their undergraduate science programs, and presents expertise areas which every teacher should possess. Outlines activities for each skill which can become part of a methods course under the direction of science educators. (DH)

Lawrenz, Frances – School Science and Mathematics, 1985

Describes changes in teacher attitudes after completion of an inservice energy education workshop. Although there was a decrease in favorable attitudes towards curricular change, there was a modest, positive effect on participants (N=132) which should help to promote energy education. (DH)

Meyer, Ruth A.; Riley, James E. – School Science and Mathematics, 1984

Imaginative ways of using calculators to explore decimal fractions with secondary school and some middle school students are given. Four explorations on terminating and repeating decimals, the length of periods, and relationships are described. An appendix presents mathematical proofs. (MNS)

Kelly, Ivan W.; Bany, Bruce – School Science and Mathematics, 1984

A random arrangement of two contrasting colors in a 20x20 array is used to facilitate students' understanding of the notions of randomness, independence, and long-run frequency. It can also be used to test some prevalent errors in probabilistic reasoning. Three activities are described. (MNS)

Cohen, Herbert; Staley, Frederick – School Science and Mathematics, 1982

The view presented is that many elementary teachers do not understand the nature of science, how the skills are useful in everyday life, and of how science content is involved in many human endeavors. Integrating science with other disciplines is thought to have potential for improving the quality and quantity of science instruction. (MP)

Smart, James R. – School Science and Mathematics, 1982

The focus is on suggestions, with examples, for teaching estimation skills. Estimating can be a very enjoyable as well as a very useful part of mathematics, helping to improve attitudes of pupils toward the subject by providing success. Estimation is shown not to be synonymous with mental arithmetic. (MP)

Pereira-Mendoza, Lionel; May, Sadie – School Science and Mathematics, 1983

Suggestions for activities are organized into categories of the community, sports, the home, travel, and nature. Each has been linked to other curriculum areas such as physical education, science, or social studies, so it is possible to use the activities as a basis for an interdisciplinary approach to the curriculum.

Berman, Barbara; Friederwitzer, Fredda J. – School Science and Mathematics, 1983

It is viewed understandable that many teachers consider fractions one of the most difficult mathematical topics to teach. School experiences need careful planning to include sequential activities which develop accurate concepts, and concepts are thought best developed by activities which move along the concrete-to-abstract continuum.

Wiebe, James H. – School Science and Mathematics, 1983

Several major factors must be considered when developing or assessing tutorial microcomputer software for mathematics instruction. Both learning considerations and curriculum considerations are discussed in some detail. (MNS)

Hennemann, A. Louise; Hennemann, Willard – School Science and Mathematics, 1983

Use of the hand-dialed, transparent, nonelectronic SEE-Calculator is proposed. Pupils can dial numbers into appropriate columns, watching the gears work; place-value concepts are enhanced. Both activities and flowcharting are suggested. (MNS)

Glass, Lynn W. – School Science and Mathematics, 1983

Reasons business and industry participate in educational support are grouped into civic duty, career education, and communication. Support is grouped into five broad categories: employment, equipment and materials, facilities, financial, and personnel. Such sources can help replace the reduced level of funding by government.
