Hypothesizes that exploring the mathematical ideas behind mathematical terms enables children to gain insight into the structure of a number system and provides a basis for powerful playing with this structure. Describes visualizing mathematical ideas for exploring aspects of mathematics. Offers rectangular numbers to link and explore structures…

This study, involving 20 normally developing 4-year olds, found no visual sequential recall differences between direct selection and scanning in task performance. However, subjects correctly recalled fewer sequential symbols represented by Blissymbols than by Picsyms, and recalled significantly fewer three-symbol sequences than two-symbol…

Discusses an introductory mathematics course for six year olds which incorporates visual reflection of essential links and relationships, broad and flexible approaches, student actions, and meaningful cooperation of students. The four topics covered are determination of attributes, symbolic representation of relations and transformations, the…

As children begin to grasp the basic functions of literacy, they become engaged in meaning-making that alternates between and/or combines oral language, written and printed symbols, drawings, and other formats. This article examines the benefits to children of an integrated approach to literacy, highlighting the Reggio Emilia approach, and offers…

Recent research demonstrates that many issues related to the structure of natural numbers and the relationship among numbers are not well grasped by students. In this article, we describe a computer-based learning environment called "Number Worlds" that was designed to support the exploration of elementary number theory concepts by…

This study investigates children's spatial cognition in the microcomputer environment created by "HyperGami." Two categories of spatial cognition have been described: spatial visualization, which involves mentally rotating, manipulating and twisting two- and three-dimensional objects; and spatial orientation, which involves the ability…

This paper examines the conceptualization and design of the Pennsylvania Audiographics Distance Education Project's (PADEP) Life Skills and Drug Education Course, and discusses the successes and difficulties of the project based on results from formative evaluation. Educators from Harrisburg, Pennsylvania, developed new courses that could be…

This paper highlights how introductory textbooks on Egyptian art inhibit understanding by reinforcing student preconceptions, and demonstrates another approach to discussing space with a classroom exercise and software. The alternative approach, an active model for spatial representation, introduced here was developed by adapting classroom…

Following an introductory paper on Pittsburgh and the arts, 57 conference papers are presented under the following four major categories: (1) "Imagery, Science and the Arts," including discovery in art and science, technology and art, visual design of newspapers, multimedia science education, science learning and interactive videodisc technology,…

This study was intended to ascertain the effectiveness of videotape recordings on the achievement of ninth grade students in citizenship classes versus achievement of students where that medium was not used. Subjects for the quasi-experimental study were 183 ninth grade students in selected high school citizenship classes in a large suburban…

A project on videodisc technology sponsored by the Illinois State Board of Education has captured classroom teachers teaching in their own classrooms to their own students. By digitizing this video instruction onto videodiscs preservice teachers and instructors have a visual learning tool that provides instant access to a variety of pedagogical…

An exploratory study developed ways to describe systematically a particular graphic organizer, the frame. For the study, 27 middle-grade teachers each constructed 2 frames on sections of fourth-grade science and social studies texts. Teachers also worked collaboratively in pairs and larger groups to produce frames. Collaborative sessions were…

A study tested the effects of between-channel redundancy on television news learning. Redundancy, defined as shared information, was proposed as an explanatory variable that considers the relationship between information in three channels: the audio, the nonverbal pictorial, and visual-verbal print channel. It was hypothesized that pictures would…

One aim of this study was to identify, in a group of unsuccessful college level problem solvers, the status and use of their declarative knowledge as revealed by students' attempts to solve novel problems in a pencil-and-paper setting. It was hypothesized that for some unsuccessful problem solvers, their problem representation could be improved by…

Two studies designed to establish classification procedures and the reliability of a learning strategy screening procedure were conducted, using 184 third and 173 fourth graders from a middle-class suburban school district as subjects. A 10-minute learning strategy screening was administered during which subjects reported which of six generic…
