This paper presents a system that makes it a simple task to create Web pages that provide explanations based on images or diagrams. The result approaches the dynamic presentations teachers are used to doing with the help of a blackboard or overhead project system. This naturally leads to the question of what constitutes a good explanation. The…

With the number and types of documents in digital library systems increasing, tools for automatically organizing and presenting the content have to be found. While many approaches focus on topic-based organization and structuring, hardly any system incorporates automatic structural analysis and representation. Yet, genre information…

This paper is focused on a central aspect in the design of a planned digital library for human movement, i.e. on the aspect of representation and recognition of human activity from video data. The method of representation is important since it has a major impact on the design of all the other building blocks of the system such as the user…

The visual instruction section of the division of educational extension of the Bureau of Education has deposited in each of 35 distributing centers throughout the country an average of 113 reels of motion-picture film. In each of these centers these will be at once, or shortly, a part of a motion picture library. The technique of local…

In the career education program of the Oregon State School for the Deaf, students from preschool through grade 12 utilize a variety of media to prepare for real, life goals. (MC)

Describes research into the adaptive function of illustrations in reading development of primary students, indicating that, for good readers, illustrations play a significant role in the early stages. This declines sharply with reading development. For poor readers, there is a progressive dependence on illustrations which appears unlikely to be…

The use of computer graphics techniques in a study of attrition at the University of Akron is outlined to illustrate potential applications. The techniques produce information that is more readily interpreted than the usual data tables. Specific software information and illustrations are included. (MSE)

Explains how Sir Joshua Reynolds' paintings and William Blake's etchings enriched the study of Blake's "The Chimney Sweeper" in a seventh-grade class. (JL)

Dittoed worksheets, posters, and charts are the basis for helping elementary school physical education students understand movement concepts. Written or pictured exercises designed by the teacher reinforce students' learning of physical skills and identify areas of confusion. (PP)

Investigates the role of visuals in the instructional and evaluation phases of a high school biology unit on the human heart. Results indicate that the instructional strategy of implementing visualization in both the presentation and evaluation phases is a viable instructional variable. Forty-four references are listed. (Author/MER)

Presented are two visual aids, the Lesson Plan Tree and the Interdisciplinary Planning Wheel, which can serve as a framework and reference for student and teacher cooperative planning of an interdisciplinary studies unit. Both planning aids are illustrated with sample learning activities on pioneer life in Ohio. (SJL)

Describes construction of two inexpensive three-dimensional models (tetrahedrons) using glass tubing and colored plastic sheeting. Diagrams show how these models are used in explaining how a point is plotted in a four-component system and how the composition of a point is deduced from its position in the model. (CS)

Examines the effectiveness of block-word diagrams in science instruction for ninth graders using directed graphs that express content structure as key concepts joined by arrows. Results include the finding that the effect of text-plus-diagram treatment compared to text-only treatment was different for learners of different ability. (CS)
