Several examples are given to show that the calculator can be a tool to enhance mathematical understanding. Expressing rational numbers (fractions) as decimals provides the content focus. (MNS)

To examine the effects of using a microcomputer in mathematics instruction, a nine-month study with 87 fifth-grade students was conducted. The group having drill-and-practice on the microcomputer improved significantly more than a group using an individualized kit, and also gained significantly in computer literacy. (MNS)

The development of a procedure for evaluating student teaching in science is presented. Selecting criteria for criterion referenced evaluation, organizing principles for the evaluation format, and application of the format are each discussed. (MNS)

How the concept of function sheds new light on one of the central tasks of algebra, that of solving equations, is discussed. Many specific examples are presented, and a theoretical basis is included. (MNS)

Because environmental education may be viewed as education in, about, and for the environment, some choices must be made about the emphasis given to each. The predecessors of environmental education are noted, followed by resource materials on out-of-school activities. (MNS)

Using Edwin Abbott's book, "Flatland," is suggested for mathematics and English classes to help students lose their fear of mathematics. Background information and comments on the book are given. (MNS)

Suggests specific topics in inferential logic which might be incorporated into the geometry course and illustrates how the use of inference schemes may help justify the effectiveness of proof techniques. (MNS)

The importance of spatial ability in facilitating curricular goals in science and mathematics is stressed. Suggestions are given about materials and activities to use and an instrument for assessing visual perception is illustrated. (MNS)

Recommendations for successful mainstreaming of mentally retarded students into the science classroom are discussed. Laying the groundwork, social integration, instructional strategies, the curriculum, and evaluation are each considered. (MNS)

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)

Five procedures that science teachers might use with students who have difficulty in reading are outlined. (MK)

This module, designed for use at the high school level as a four- to eight-hour topic, includes: the geometry of a sphere, the coordinate system used to describe points on the earth's surface, parallel and meridian sailing, and the solution of right spherical triangles. (Author/MK)

This paper discusses a technique, challenging students to solve problems published in mathematics periodicals, which has been used successfully with gifted students in a regular high school class. (Author/MK)

Suggestions for outdoor mathematics activities include six each for primary-age and intermediate-age children. (MK)

The need for a mathematics program that "emphasizes the humanness of its young clients" is discussed. Early experiences in mathematics are suggested. (MK)
