Graphs equations in two variables using a BASIC screen-sweep program that generates solutions to equations by applying the intermediate value theorem. Provides suggestions for investigations that result in graphs of a butterfly, the Cheshire cat, the Trisectrix of Catalna, E. T. waving goodbye, a praying mantis, and others. (MDH)

This paper reviews the research literature on relationships between the integration of microcomputers and students' learning of mathematics in secondary schools. Following a brief introduction and statement of the problem, annotations are provided for 31 studies in the following subject categories: (1) the extent of computer use in secondary…

The definition of a microcomputer along with examples and resource information for such systems, the advantages of microcomputer kits, and the value of the microcomputers to the student are discussed. (MN)

The use of microcomputers to aid geometry instruction is emphasized through discussion of a program written in BASIC which provides for experimenting with polynomial curves. The program listing is included. (MP)

Describes a system of computer assisted instruction geared primarily toward high school and university students involved in numerical analysis and optimization. Also describes (in detail) one of its modules to illustrate the general philosophy of the system. This module focuses on the simplex method. (JN)

Relates one secondary geometry teacher's experiences learning and using the computer program "Geometer's Sketchpad." The article describes the program and provides examples of ways this teacher uses it in combination with more traditional teaching tools. (SM)

The purpose of this study was to conduct formative and summative evaluation for Computer Integrated Instruction (CII), an alternative use of computer-assisted instruction (CAI). The non-equivalent control group, pretest-posttest design was implemented with the class as the unit of analysis. Several of the instruments were adopted from existing CAI…

Field tests were conducted to evaluate theory-based computer-video instructional modules designed to teach or review concepts and operations for factors, prime numbers, and fractions. (MNS)

Describes a study at a secondary school in Glasgow (Scotland) in which teacher-pupil and pupil-pupil pairs of users collaboratively used eight commercial educational software programs, four related to mathematics and four to English language teaching, to determine whether software style affects patterns of interactions. (23 references) (LRW)

The concerns of two teachers at a school where computer-integrated instruction was being used in five second-year algebra classes were studied. High levels of personal and management concerns, coupled with low refocusing concerns, were found. Both teachers were judges as mechanical users of computer materials. (MNS)

The history of competency testing and legal issues related to it are reviewed briefly in light of the responsibility of school districts for providing remediation programs for students who have failed the test. The mathematics competencies of the state of Idaho are identified and keyed to four sets of readily available, secondary level Apple…

Using personal-sized microcomputers (8K), students learn to operate equipment and program in BASIC. They complete computer-assisted instruction lessons and select, design, operate, demonstrate, and document their own original programs in this one quarter, high school course. Course objectives, activities, materials, and evaluation are outlined.…

Uses Derive as an instructional tool to investigate asymptotic behavior of rational functions. Activities focus on reducing manipulation and computation and on generating multiple examples to focus on discovery of the concept rather than a summary of rules. (MLN)

Suggestions for using four-function calculators, programmable calculators, and microcomputers are considered in this collection of 36 articles. The first section contains articles considering general implications for mathematics curricula implied by the freedom calculators offer students from routine computation, enabling them to focus on results…

Discussion of the use of electronic networks for learning activities highlights the Noon Observation Project in which students in various locations measured the length of a noontime shadow to determine the earth's circumference. Electronic pen pals are discussed, and the roles of the network and of the class are described. (LRW)
