The concept of statistical significance is explained, with specific numerical illustrations. (MNS)

This paper reviews meta-analysis procedures and several meta-analysis findings related to science teachings. Several generalizations are offered, one which indicates that instructional techniques which help students focus on learning (preinstructional strategies, increased structure in verbal content of materials, use of concrete objects) are…

This review discusses instructional materials as the physical media through which the intents of the curriculum are experienced. Studies of innovative science curricula are considered, as well as the role of textbooks. (MNS)

The retooling of elementary school teachers in science may provide some relief for the shortage of science teachers. An innovative program is described, with data presented to depict teachers' concerns, state anxiety, and attitudes. (MNS)

Data were collected from 293 fifth-grade students. Significant positive relationships were found between science achievement and all of the attitudinal tendencies tested. (MNS)

Research on the usefulness of calculators in mathematics instruction is cited, and some activities using calculators to develop skills with reading numbers, counting, basic facts, multiplication and division, problem solving, estimation, percentages, decimals, patterns, probability, and games are described. (MNS)

Data were collected by pencil-and-paper instruments from 33 students in grade 10 in Perth, Western Australia. Data indicated that students were only slightly knowledgeable about energy and energy conservation; they had slightly positive attitudes toward energy conservation. (MNS)

Surveyed were 220 teachers in grades one-three in 11 states on their use of 11 devices for teaching mathematics. The percent of teachers who never or seldom used the listed manipulatives ranged from 40.8 to 74.7. (MNS)

Examined is the effectiveness of a computer software package designed to be consistent with a fraction strip chart model. The materials are described; they were used with three fourth-grade classes, while two other classes acted as controls. (MNS)

This study was designed to determine the effectiveness of two microcomputer instructional games in teaching probability and measurement estimation to 78 preservice elementary school teachers. The probability game did not seem effective, and the estimation game was only marginally effective. Patterns of change are discussed. (MNS)

Fourteen suggestions for improving mathematics instruction for bilingual students are discussed. The role of language in learning mathematics and in solving problems is the focus of a number of suggestions. (MNS)

Investigated was a sequence of computer-based activities on estimation with 108 students in grades 9, 10, and 12. The activities were appropriate for students at each grade level; each class improved their estimation scores significantly. (MNS)

Reports the proceedings of the Wingspread conference on integrating science and mathematics teaching and learning. Discusses (1) a literature review on integration of science and mathematics education; (2) development of definitions of integration; (3) specification of guidelines for infusing integrated teaching and learning into science and…

The study sought to determine how integrating science and mathematics in a seventh-grade physics unit affected attitudes and achievement in science. Two above-average and two average classes were involved. Scientific attitudes of the average integrated group improved, as did achievement of the above-average integrated group. (MNS)

This study demonstrated that abstracts composed with the aid of a computer were rated higher than those without a computer. Categories assessed included spelling/punctuation, organization/design, sentence structure, clarity, and overall quality. Subjects were 68 students participating in the 1984 Secondary Student Training (SST) Research Program…
