This report is part of a long-term research on the construction of mathematical meanings through the interaction with various technologies. The research involved a set of teaching experiments based on body motion with sensors and calculators at different school levels, from kindergarten to secondary school. Here I refer to the one developed in a…

This paper focuses on the cognitive processes that occur while students are exploring motion graphs. In a classroom experiment, we examine how high-school students (aged 17), with backgrounds in calculus and physics, interpret the graphs they create through drawing the path of the movement of their hand with a computer mouse. Based on recent, and…

Research has begun to address the question of transfer of language usage patterns beyond the idea that people's native language (L1) can influence the way they produce a second language (L2). This study investigated bidirectional transfer, of both lexical and grammatical features, in adult speakers of English and Spanish who varied in age of L2…

This paper examines the idea that particular representations differentially support and enhance different cognitive processes, in particular different types of reasoning. Five case studies were conducted consisting of detailed observations of pairs of middle-school students interacting with a computer-based learning environment. The software…

A musical ear is widely accepted as an essential ingredient in the education of successful music students. Most music educators believe that without a well-developed ear, it's impossible for a musician to function on a professional level as a teacher, conductor, performer, or composer. The purpose of this article is to introduce the concept of…

The aim of this paper was to describe the changes in one student's ideas about force and one-dimensional motion concepts and portray the relevant metaconceptual processes that she engaged in during the implementation of metaconceptual teaching interventions. Metaconceptual processes involves metacognitive processes that are directly acting on or…

A gender gap between boys and girls has been reported in computer usage. Graphics may play a role in bridging that gap because of their motivational value. The literature reports gender differences regarding graphic content, color, detail, size, and movement. Based on these findings, preliminary design guidelines for graphics in computer-based…

This practicum addresses the problem of limited interaction between physical therapists and families of developmentally delayed/physically impaired preschool-age children. A program was developed in which the physical therapist was videotaped handling and exercising a child, while explaining the purpose of the movements and instructing the parent…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on students' thinking regarding their views on friction. Students (N=47) were…

This teaching guide for motor development in the primary grades describes various areas of concern in motor development and suggests activities for the development of young children in each area. Section I discusses the importance of motor development. The next six sections define and describe particular areas of motor development and suggest…

The papers in this document represent preliminary results of a study which is part of a 3-year project being conducted by the Educational Testing Service in cooperation with the New York City Board of Education, with support from the Carnegie Corporation of New York. This document is divided into seven sections: (1) Introduction, (2)…

Why and how architecture and interior design can stimulate exploratory locomotion is discussed in terms of research and testing into human response. Two kinds of locomotion are defined, exploratory and habitual, with regard to locomotion and behavior responses to the architectural environment. Measuring responses with a hodometer is outlined with…

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Describes the implementation of a trajectory-plotting program for a microcomputer; shows how it may be used to demonstrate the focusing effect of a simple electrostatic lens. The computer program is listed and diagrams are included that show comparisons of trajectories of negative charges in the vicinity of positive charges. (TW)
