Human cognitive architecture is a constant in a continually advancing educational technology environment. That architecture should be central in determining which technologies should be adopted and how they should be used. In this article, cognitive load theory is used to indicate aspects of human cognition relevant to instructional design, with…

The authors hypothesize that a means-end strategy places a load on cognitive processing capacity which retards knowledge acquisition. Three experiments using trigonometry problems with high school students were conducted in which the problem goal was modified to disrupt strategy used by novices. Results supported the authors' hypothesis.…

The expertise reversal effect occurs when a learning procedure that is effective for novices becomes ineffective for more knowledgeable learners. The authors consider how to match instructional presentations to levels of learner knowledge. Experiments 1-2 were designed to develop a schema-based rapid method of measuring learners' knowledge in a…

Four experiments supported the hypothesis that, when learning to use equipment such as computers, if the material to be learned has an intrinsically high degree of interaction between elements, then learning might be facilitated by not having the equipment present. Thus, an analysis of intrinsic and extraneous cognitive load can lead to…

Research of expert-novice differences is reviewed seeking to show experts possess a large body of domain specific knowledge. It was postulated that experts possess schemas enabling them to classify problems, call up the appropriate automated rules, then apply these to obtain the solution. (DC)

Reviews research on (1) schemata acquisition while learning mathematics and techniques for detecting schema in mathematics learners; and (2) assessment of the distribution of cognitive resources while learning mathematics that lead to the design of instructional techniques to facilitate schema acquisition.
