Noting that formative research on educational computer software has traditionally focused on comprehensibility, appeal, and usefulness, this report argues that these three elements tell us very little about the actual role that the formative researcher plays in the instructional design process. This paper outlines the complexity of the tasks and…

Presents author's view of how computer graphics produced in the classroom enhance mathematical concepts teaching. Specific concepts and related graphics presented include the convergence of power series and the Central Limit Theorem. Formal versus informal instruction, computer assisted instruction versus teaching, and requirements for future…

Reviews research describing computer functions of construction-oriented computer environments and evaluates their contributions to students' learning of geometry. Topics discussed include constructing geometric concepts; the use of LOGO in elementary school mathematics; software that focuses on geometric construction; and implications for the…

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)

Describes experiences in mathematics with the Renaissance Project, a project designed in the United Kingdom to demonstrate the potential for interactive multimedia in higher education. Highlights include using HyperCard for mathematics software; courseware advantages; copyright; and courseware design issues, including navigation, examples, and…

Contends that, though much attention is given in mathematics to the problem of sensitizing people to the need for identifying elements of a situation and representing them symbolically, little or no effort is devoted to the problem of helping them express the relationships among these elements.

Discusses the use of educational technology for science and math instruction in elementary and secondary schools through conversations with six curriculum specialists and administrators. Highlights include the use of IBM and Macintosh hardware and software; hand-held computers; integrated learning systems; math workstations; computer simulations;…

Argues that students should have dynamic perceptual experience with the concepts central to circular functions. Includes a computer program, designed for Apple II, to provide such experience. (PK)

Describes and analyzes a study of the influence of computers on pupils ages 12-14 in Spain. Four fields of action are defined: (1) research; (2) teacher training; (3) student and teacher activities; and (4) the development of teaching materials. An example of the curricular development of units for mathematics is included. (Contains 21…

Discusses computer methods for finding roots of polynomials. The program provided finds rational roots and prints the roots as rational numbers. (PK)

Describes the use of a working conference to train teachers and education students to use the computer in mathematics education. Group work is discussed that focuses on two main components of the conference--software evaluation and lesson creation; and adaptations for Eastern European schools with few computer resources are described. (Contains…

Description of a validated computer assisted instruction (CAI) program (The Addition Tutorial) illustrates how four critical components for instruction--learning principles application to instructional design; sufficient database; adequate motivational system; and delivery system which provides teacher learning environment control--might be…

Reviews of the courseware "Discovery! Experiences with Scientific Reasoning" and "Guess My Rule" are given. Discusses the accompanying manuals, the relative ease of use, and content of the programs. (PK)

Criticizes the statistical methods used in a previously published article that compared a commercially produced computer program with traditional teaching methods. Measures of instructional effectiveness are described, the assignment of student pairs is examined, and the use of blocking variables with analysis of variance is discussed. (LRW)
