Engineering drawing is valuable in capturing geometric features, conveying engineering ideas, and creating a blueprint of the intended product. Engineering students usually perform orthographic projections, imagining a 3D situation and sketching its 2D representation. That requires imagination and mental visualization, determined by the learner's…

This study explores the dynamic, interactive nature of digital drawings and writing in a knowledge building community in which students used a multimedia online environment--Knowledge Forum--to represent and advance ideas in the field of optics. The research employs a mixed-methods case study to collect and analyze multimedia notes created by 22…

This paper explains the design of a graphics-based virtual environment for instructing computer hardware concepts to students, especially those at the beginner level. Photorealistic visualizations and simulations are designed and programmed with interactive features allowing students to practice, explore, and test themselves on computer hardware…

We developed and tested a lesson plan for active teaching of diffusion in secondary schools (grades 10-13), which stimulates understanding of the thermal (Brownian) motion of particles as the principle underlying diffusion. During the lesson, students actively explore the Brownian motion through microscope observations of irregularly moving small…

Changing practices in schools is a very complex endeavor. This paper is about new practices we prompted to foster collaboration and critical reasoning in science classrooms: the presentation of pictures representing different perspectives, small group synchronous argumentation, and moderation of synchronous argumentation. A CSCL tool helped in…

To study the effects of learner generated imagery on the learning of science material a series of three experiments were conducted. Interactive graphics using the plasma panel, a touch panel interface of the PLATO system, were used to simulate the topography and functions of a battery to teach elementary concepts in electrochemistry. Following a…

During the first 12 weeks of an applied calculus course, two classes of college students studied calculus concepts using graphical and symbol-manipulation computer programs to perform routine manipulations. Three weeks were spent on skill development. Students showed better understanding of concepts and performed almost as well on routine skills.…

The effects of the integration of art and science through instruction in computer art graphics on learning geology were studied with 53 college students and 189 comparisons in the same geology class. Results indicate that building representations of scientific concepts through computer art may improve students' achievement. (SLD)

Two computer assisted instruction programs tested the effects of plain and enhanced screen designs with or without information about those designs and task-type on time and learning. Subjects were 140 fourth grade students in Lincoln, Nebraska who had extensive prior experience with computers. The enhanced versions used headings, directive cues,…

This volume contains 53 articles grouped under five headings: (1) Research (14 papers on such topics as cognitive style and cognitive strategies, visual literacy training, and the impact of diagrams, type styles, and computer graphics on learning); (2) Theory (nine papers on such topics as the development of visual literacy concepts, cognition and…

This study explored computer-based image processing as a study strategy for middle school students' science concept learning. Specifically, the research examined the effects of computer graphics generation on science concept learning and the impact of using computer graphics to show interrelationships among concepts during study time. The 87…

Describes a study that investigated the effects of visual display within a college computer-based learning program that taught computer programming language through analogies. Three types of visual displays (text, static graphics, and animation) are compared, and assessment measures that included posttests and attitude questionnaires are…

Provides an interim report on a project whose goal is to provide subject access to the knowledge of mankind at least as well as the skilled reference librarian. Classification and concept formation are discussed in terms of four modules: diagnostics of information-seeking behavior, network interface, subject access, and graphic interface. (EM)

This study explores the instructional impact of using computer multimedia to integrate metaphorical verbal information into graphical representations of biotechnology concepts. The combination of text and graphics into a single metaphor makes concepts dual-coded, and therefore more comprehensible and memorable for the student. Visual stimuli help…
