This paper was prepared in response to the Conference Board of Mathematical Sciences recommendations for the preparation of secondary teachers. It shows how using trigonometry as a conceptual tool in spreadsheet-based applications enables one to develop mathematical understanding in the context of constructing geometric representations of unit…

Inequalities are considered among the most useful tools of investigation in pure and applied mathematics; yet their didactical aspects have not received much attention in mathematics education research until recently. An important aspect of teaching problem solving at the secondary level deals with the notion of equivalence of algebraic…

Computer Science formal education brings together old-timers from two computer-literate cultures. The curriculum is oriented toward the academic community, whose interest is in the abstraction, solution, and proofs of algorithmic problems, whereas many students are technology users, whose main interest is the manipulation of the products of…

Investigates the extent to which computers were being used by middle and high school mathematics teachers in Missouri. Develops an understanding of the basis for teachers' decisions regarding the use of computers--or lack of--in instruction. Reports that the teachers did not use computers for purposes other than drill and practice. Contains 44…

Reports on implementation of a World Wide Web site for teacher professional development. Presents results of pilot project involving four high school and middle school mathematics teachers. Highlights three specific ways in which teachers can benefit from Web: (1) consistent opportunities for reflection and sharing; (2) shortened cycle for…

Spreadsheets have become popular tools for exploring mathematical patterns and building conceptual understanding of variables and functional relationships. Presents examples of students' work to illustrate multiple paths of inquiry, generalization, and mathematical reasoning. Supports effective investigation of patterns and functions for students…

Examines the relationship of microcomputer simulation graphics and alphanumeric modes of data presentation to ninth-grade biology students' science process skills and conceptual understanding of selected science topics (N=64). Concludes that use of microcomputers and appropriate software can result in significant learning and understanding of…

Describes several exemplars of software that emulate and incorporate machine-supported aspects of cognitive apprenticeships in science and mathematics. Concludes with an evaluation of software against cognitively guided principles and with a summary of the difficulties associated with creating and implementing machine-supported apprenticeships.…

Reports on a pilot program studying the use of computer software to enhance spatial skills presumed to be related to success in calculus. Addresses the effects of such a program on female and minority students. Results indicated that the combined effects of the computer, drawing and drafting, and gender variables explained 31% of the variance in…

Presents a study that introduces data logging using portable computers as part of an investigative approach to science. Working with control and experimental classes of 14- and 16-year-olds, results suggest that data logging can have an impact on graphing skills at age 14 which is not necessarily repeatable at age 16. (Author/AIM)

Discusses the potential of computers in teaching laboratories to spare the lives of animals; however, it is felt that in areas of physiology education, virtual labs are not as desirable a learning experience for advanced students as live animal labs. (Author/AIM)

Presents a comparative study of the effects of feedback on students who learned to solve algebraic factorization problems in an intelligent learning environment. Concludes that when the same error comments were used in both experiments, similarities were observed in the learning paths of the respective student groups. Contains 41 references.…

Covers research conducted within the past 10 years on the topic of using computer models and simulations to aid science instruction at the precollege level. The research is categorized into three main areas: (1) students running preprogrammed simulations; (2) students creating dynamic models using modeling environments; and (3) students using…

Studies the effect of V-Scope activities on the performance of 11th-grade students in analyzing kinematics graphs. Students were challenged to construct different kinds of graphs using their own movements as well as the motion of a dynamics cart. Results indicate that the V-Scope kinematics laboratory activities can promote kinematics concepts and…

Describes the development of a model for delivering the first course in computer programming to large and diverse classes. Presents an integrated approach that emphasizes program-design skills and problem-solving skills, and motivates students to learn by active processes. Team teachers, tutors, and lab demonstrators integrate lectures, tutorials,…
