What students need to know in a world where most computations are done by machine is discussed. Needed changes in the mathematics curriculum are then detailed in relation to mental arithmetic, numeration, decimals and fractions, paper-and-pencil computation, order of operations, problem solving, and instruction on calculator use. (MNS)

Suggested are investigations of rational numbers and their decimal representations where a computer generates the data for explorations. Conjectures and two program listings are included. (MNS)

The purposes, materials, and roles of teachers and students in developmental and practice lessons are contrasted. Two lessons designed to help students acquire understanding of geometric figures and of place value and two games for each are included. (MNS)

Provided are follow-up activities for having students explore the concept of line symmetry. Using a mirror to move a pattern; finding patterns with one, two, or four lines of symmetry; finding asymmetrical patterns; deciding if patterns are different; and solving the problem of finding all patterns possible are discussed. (MNS)

Reviews research on effects of teacher expectations on student achievement; suggests faulty teacher expectations could affect mathematics achievement when certain conditions are present; and presents recommendations which address teacher expectation behaviors to serve as guidelines for improving classroom environment. (MBR)

Findings are reported from an intensive study of 10 students over three school years spanning the transition from primary to secondary school. Detailed test, interview, and observational data were analyzed to examine the impact of secondary school and secondary school mathematics on the mathematical behavior of the 10 students. (JN)

A week-long build-a-city project is described which lets students become familiar with the history of the five Platonic solids (tetrahedron, octahedron, hexahedron, isosahedron, dodecahedron) and then use these solids to create a city using posterboard and construction paper. (MNS)

Principles on which the teaching of mathematics is based are discussed. Sections concern the skill principle, the curriculum principle, and learning strategy, with many classroom illustrations. (MNS)

An advanced placement calculus program is described that incorporates IBM personal computers, conference telephone connections, modems that transmit computer signals over the phone lines, OPTEL graphics that allow the users to "write" on their computer screens, and a sophisticated package of calculus software used for homework…

Describes a field test and results of a new didactic teaching method involving resource-based learning to teach various aspects of mathematics and science (fractions, magnetism, planets) to elementary aged hearing impaired student in Iraq. The dramatic improvements in language for learners is described and implications of the methods are…

Presents reviews of the following mathematics software designed to teach young children counting, number recognition, visual discrimination, matching, addition, and subtraction skills; Stickybear Numbers, Learning with Leeper, Getting Ready to Read and Add, Counting Parade, Early Games for Young Children, Charlie Brown's 1,2,3's, Let's Go Fishing,…

Describes a special application of the microcomputer for small and large group instruction called Computer-Guided-Teaching (CGT). Effective teaching strategies incorporated in CGT lessons are discussed, and a description of a formal geometry course illustrates their use in CGT lessons. (MBR)

To help students develop measurement skills using metric units, an activity on making a box is described, with a worksheet for students. A second article discusses graphing elementary functions with a real domain, while a third article describes computer-assisted practice in graphing sine and cosine functions. (MNS)

Reviews the Curriculum Referenced Tests of Mastery that are intended to measure achievement, with the emphasis on measuring what a student has learned rather than predicting future success in school, concluding that the tests are worthy of consideration by any district. (HOD)

Discusses the nature and importance of iconic learning (image-related) and a medium to facilitate assessment at the iconic level of knowing. The medium consists of a series of self-inking rubber stamps made with iconic representations of numeration blocks and sticks in denominations of 1, 10, and 100. (JN)
