Noting that everyday creativity often requires imaginative insight, this book provides opportunities for children and adults to invent and problem solve by confronting puzzling scenarios that invite visual imagination. Each of the 71 activities in the book begins with a scenario that promotes speculative imagination. In the creative- and…

Presents activities which highlight major concepts of linear programming. Demonstrates how technology allows students to solve linear programming problems using exploration prior to learning algorithmic methods. (DDR)

The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

The focus of this article is on how computer graphics can be integrated throughout the engineering graphics curriculum to increase visual perceptual skills. Visual perception is defined, the need to develop it is described, and methods which engineering graphics educators can use to develop it are outlined. (KR)

This study shows how users access relevant information in a visualized document space and determine whether BiblioMapper, a visualization tool, strengthens an information retrieval (IR) system and makes it more usable. BiblioMapper, developed for a CISI collection, was evaluated by accuracy, time, and user satisfaction. Users' navigation…

Contemporary trends in education reflect a shift from traditional teacher-centered approaches to more student-centered approaches to learning. Empowering students in their own learning is facilitated by teaching them effective meaning-making strategies that support active participation in their own learning. Making this happen requires using…

The effect of intervening use of molecular visualization software was tested on 73 first-year general chemistry students. Pretests and posttests included both traditional multiple-choice questions and model-building activities. Overall students improved after working with the software, although students performed less well on the model-building…

As more archival metadata and archival records become available online, providing effective interfaces to those materials is increasingly important to give users access. This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures,…

This study was undertaken to explore the use of a digital camera for mental imagery training of a vocational task with two young adult men with Down syndrome. The results indicate that these particular men benefited from the use of a collaborative training process that involved mental imagery for learning a series of photocopying operations. An…

Teachers tend to design worksheets to assist their students to develop their spatial skills. Many secondary schools students may not have sufficient concrete experiences to tackle abstract reasoning in geometrical concepts competently. In addition, students who are non-visual and spatial learners may have difficulties in learning geometrical…

This two-part article discusses the role of the physical environment in adult learning. In the first part, two activities--environment introduction and visualization--are discussed as ways to develop an awareness for improving the learning environment. In the second part, two planning activities--mapping and geometric coding--are discussed as ways…

This paper presents a historical overview of visualization as a human problem-solving tool. Visualization strategies, such as mental imagery, pervade historical accounts of scientific discovery and invention. A selected number of historical examples are presented and discussed on a wide range of topics such as physics, aviation, and the science of…

Out of the school reform movement of the eighties have come recommendations for professional development schools, site-based management, and teacher empowerment. Such initiatives can be implemented only in environments where continuing pursuit of new knowledge exists at every level. There is a pressing need for educational models that strive to…

To examine the role of phonetic code in memory, a study investigated the use of phonetic recoding strategies in fifth and sixth graders identified as good and poor readers. Subjects--120 students with IQ scores in the average range--were divided evenly between both grades. Thirty subjects from each grade who scored above the 50th percentile on the…
