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…

This paper begins with a description of the context and background of cognitive research into knowledge acquisition and representation for computer based training. The nature of concept maps is alluded to and examples are given of the ways that maps can facilitate knowledge elicitation. It is noted that: (1) the concept knowledge in this research…

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.…

Described are examples of classroom exercises that use interactive graphics software for personal computers to enhance the teaching of statistical concepts by allowing students to generate multiple examples, make conjectures, and verify their findings about the concept. The transfer of this interactive tool to other subject areas is suggested.…

Research employed two types of redundancy, each having two levels, at each stage of a programed sequence of non-verbal concept learning tasks. One type involved amount of variation and repetition of exemplars; the other, strength of feedback. A researcher presented tasks to 4th, 5th, and 6th graders, simulating a computer graphic display. The…

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 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…

Describes and illustrates the Monomial Sums Approach, a graphical learning strategy, facilitated by microcomputer capabilities that allow easy manipulation and exploration of graphical representations of polynomial functions. Reduces emphasis on memorized rules in favor of qualitative understanding of functional behavior, visualization of…

Describes the use of a microcomputer-based laboratory (MBL) in teaching the concepts of heat and temperature to eighth grade students. Discusses the advantages of being able to instantly display the results of their experimentation with the use of temperature and light probes, and heat pulsors. (TW)

Contains abstracts of presented papers which deal with teaching materials and methods in physiology. Includes papers on preconceptual notions in physiology, somatosensory activity recorded in the dorsal root ganglion of the bull frog, and the use of the Apple Macintosh microcomputer in teaching human anatomy and physiology.

A study was made of the learning effects of information mapping; i.e., the technique of organizing materials on the printed page in a format which clearly illustrates the order and organization of the materials. The investigation of the effects of information mapping and information-mapped feedback on achievement, time variables, and attitude…
