Children learn arithmetic procedures by rote, rather than by constructing them with an understanding of numbers. Rote learning produces lack of flexibility, nonsensical errors, and other difficulties. Proposed is a theory of conceptual understanding and its role in learning and executing arithmetic procedures. The basic hypothesis is that…

This study used a microcomputer program which diagnosed and remediated an alternative conception of velocity. Results show computer simulations are credible representations of reality and that the remedial part of the program produces significant conceptual changes in students holding the alternative conception.

The Transparent Computer simulation was developed to address the educational system's need to provide the basic skills and knowledge that are required to understand computers and interact with them. Intended to be integrated in the computer literacy program in elementary and junior high schools, the Transparent Computer is an example of an…

The Transparent Computer, a computer simulation designed to teach programming concepts to non-programmers, provides a graphic representation of the computer and illustrates information flow within the units of the computer. The emphasis of the simulation is on the acquisition and application of concepts and comprehension of the structuring of…

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

This study explores a learning model which suggests that a concept is acquired first through manipulation of concrete objects followed by transformation of the concrete objects into semi-concrete representations, followed by internalization of the concept through abstract representations. Microcomputer simulations of manipulative activities were…

This study examined learning by individuals and groups in a computer environment. Individual interactivity as a function of group size was investigated by focusing on various modes of interaction available to students while they completed activities using a computer. The activities, which involved manipulation of pictures of batteries, bulbs, and…

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.

Many feel that an advantage to using computer simulations in science teaching is that they give students the opportunity to witness or perform experiments which might otherwise be too expensive, time consuming, or dangerous for them to do. Simulations attempt to mimic the kind of experience students get in a laboratory and help students learn new…

This publication contains a selection of science education research papers, beginning with an overview of trends in science education cognitive developmental research and theory in the United Kingdom. Papers that follow focus on developments in studies of thinking and reasoning, including work on concept mapping and conceptual change. Closely…
