Visuals play an important role in the teaching and learning of science and should be embedded within and supportive of authentic science inquiry. Both researchers and teachers believe that visuals have a great deal of potential to help students understand science, but in practice, these visuals do not always live up to their promise. Teachers need…

Outlining, making data tables, and sequencing events are commonly used for teaching specific topics in science but not as general learning tools. Discusses how the teaching and application of these visual representation techniques helps students realize their usefulness as learning tools and to learn more efficiently. (LZ)

Discusses the use of videodiscs to increase students' comprehension. Benefits of adding visual images to learning activities are discussed, videodiscs as sources of data for students to analyze are considered, and an example is given of using videodiscs to illustrate concepts in a chemistry class.

A study of the ways science students transformed their teacher's description of cells suggests that learning is multimodal, arising from the interaction of visual, verbal, and linguistic communication. It demonstrates that learning is a process of selection, adaptation, and transformation of information across communication systems. (Author/SK)

The Image Processing Technology Project explores the possibility of using digital image processing in mathematics and science education. Describes the origin of the project and reports the results of a 4-week teacher workshop that trained over 80 teachers in the techniques and technology of image processing. (MDH)
