In this paper a class of regular surfaces, generated by rotation and twist of a rigid line segment, is considered. Firstly a complete description of those surfaces by means of local charts is obtained and then its orientability is characterized in terms of the number of half-twists, taking into account their direction (clockwise or…

Technology offers ample opportunities to bring reality into the classroom. Students and teachers nowadays have many tools to work in an authentic way with real data in mathematics and science education. However, much research and development are still needed to create a consistent learning trajectory out of the many exciting single activities.…

This review examines the use of spreadsheets to introduce students to elementary concepts of mathematical dynamical systems. Key definitions from this field as well as specific assignments that were given as part of an elective mathematics course are discussed. (LZ)

Describes the use of computer assisted instruction at North Carolina Agriculture and Technical State University in freshman and remedial mathematics to cut down high attrition rates and weed out quickly the students who can't adapt to the vigors of engineering course work. (Author/DS)

Presents the work of Newton in thermometry and argues that it is a quite distinguished work in this area and exemplifies Newton's brilliance as an experimenter. (PR)

Discusses the dynamics and outcomes of an unplanned classroom activity that developed from the integration of the use of spreadsheets with the study of the characteristics of previously collected seashells, specifically their color, size, shape, texture, and any other obvious differences. (JJK)

Presents a brief overview of the school organization in Sweden and summarizes the results of large-scale computer experiments conducted during the last five years. Focuses on mathematics. (DC)

Provides methods for cooperative, student investigation of weather data similar to methods currently used by atmospheric scientists. Utilizes spreadsheets to focus on the analysis and interpretation of wind frequency data for a small town in Oregon. (JJK)

The primary purpose of the 1994 Mathematics/Science Education and Technology Symposium was to help foster the exchange of information related to the research, development, and applications of learning and teaching using information technology in mathematics and science educations. The theme "Emerging Issues and Trends" was identified to…

This document promotes computer symbolic mathematics and computer algebra as ideal instructional materials for mathematics, science, and engineering students. Further, computer algebra is viewed as appropriate for all students throughout the mathematics curriculum, by serving a vast area of mutual reinforcement and cross-motivation between…

Describes how technology instruction is incorporated in preservice teacher instruction at Georgia State University. Discusses the network technology and computer software and hardware introduced; transferring technology into students' teaching; and assessment via e-mail discussion. (AEF)

This study summarizes data collection activities associated with the first two years of a large scale project involving teachers of science and mathematics with computers. The innovation being implemented in the project is that of using computer based strategies directly in the teaching of science and mathematics in the classroom and laboratory.…

This module is part of a series designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. This module is used to introduce the biology student to differential calculus, a…

Proposes to modify the procedure proposed by Abelson and diSessa to produce a polygonal path with vertices that lie exactly on an ellipse. Provides a detailed proof. Implements a limiting process to produce the best possible approximation to any ellipse for any given screen resolution. (CW)

Computer-assisted-instruction software was developed to supplement the conventional lecture-laboratory mode of instruction with another instructional aid for learning science in an individualized, nonthreatening environment. This development project was designed to teach physical concepts, mathematical techniques, and problem solving strategies.…
