In less than two decades the electronic digital computer has evolved from a high-speed replacement for the abacus to a full-fledged partner in dialogue with humans. By its very nature, on-line computing thrusts the user into an entirely different environment than does conventional batch processing. The problems inherent in a person's being made a system(More)
This study measured collaborative problem-solving processes and outcomes in a computerbased knowledge mapping environment. One hundred and twenty Asian American high school students were randomly assigned to be either a group leader, whose responsibility was to construct the map, or a group searcher, whose responsibility was to seek information and access(More)

The purpose of this study was to determine the effect of practice in manipulating 2- and 3-dimensional (D) wireframe images on a learner's ability to visualize 3-D objects. Practice, either rotational or not, consisted of visualizing 2- and 3-D objects generated by personal computer (PC)-based computer-assisted design software. Results indicated that(More)
The first part of this article will review the status of technology and educational reform; the second will treat traditional approaches to problem-solving measurement common today in technological settings; and the third will propose how problem-solving assessment may change and, in particular, the role that authoring strategies may play in measuring(More)
