One approach to the study of cognitive processes highlights the distinctions between expert and novice problem solvers. This approach attempts to discover how experts and novices differ in the way they organize, retain and use domain related knowledge. It appears to some that what is learned from expert-novice research can help teachers to teach…

This investigation examined the relationship between problem solving ability and the criteria used to decide whether two classical mechanics problems could be solved similarly. The investigators began by comparing experts and novices on a similarity judgment task and found that experts predominantly relied on the problems' deep structure in…

Most of the "talk" about the role of mass media in the Third World is generated by politicians rather than by professional communicators. The "Developmental Play Model" treats media experience as an encounter with the "self" and considers the "self" as an integral part of the mass communication process. The…

To examine the effectiveness of various writing devices, a study used Richard Carter's Signalled Stopping Technique (SST) to compare these devices as used in two student-authored science stories. The SST indicates how messages are mentally processed, and uses the following seven stops: (1) C (confusion); (2) R (reread); (3) Q (question); (4) T…

Systematic observations of thousands of high school students in the California Mentally Gifted Minors/Gifted and Talented Education programs identified five principles underlying the development of high level thinking skills in this population: (1) Exceptional performance on any criterion requires mutually reinforcing antecedents, the effects of…

Responding to recent advances in developmental and cognitive science research on knowledge acquisition, this report presents a theoretical framework for analyzing cognitive development as a process of learning. The first section summarizes three developmental characteristics recognized in both the Piagetian and the quantita experimental tradition:…

Meaningful use of language involves intending to have an effect and intending the audience to recognize that aim. In a Freudian modification of this premise, allowing for different levels of intentional awareness, writing can be discussed in terms of how writers intend to affect readers, as well as how aware they are themselves of their intentions…

This paper discusses the creation of analytic categories that were applied to behavior in quite different, contrasting settings and that at the same time retained their ecological validity. In Project Follow Through, behavior stream observations were conducted on 20 second-grade children for an entire school day. To study the structure of behavior…

Research on text organization has demonstrated that reading is responsive to the number and complexity of idea units or propositions in a text, and that the capacity of children to recall information is responsive to the relative importance of the idea units. A study was undertaken to examine an extension of these propositions: namely, that…

Because it provides students with a strategy for the transfer of attributes from a familiar to an unfamiliar topic, the use of analogies can improve memory, increase specific knowledge, and encourage more critical evaluation of information. Analogies have been used to help students understand health and science materials, improve their vocabulary,…

The product of researchers' efforts to develop a computer processor which distinguishes between relevant and irrelevant information in the database, Spreading Activation Processor for Information Encoded in Network Structures (SAPIENS) exhibits (1) context sensitivity, (2) efficiency, (3) decreasing activation over time, (4) summation of…

Decimal numbers have become an increasingly important topic of the elementary and junior high school mathematics curriculum. However, national and state education assessments indicate that students have incomplete and distorted conceptions of decimal numbers. This paper reports initial data from a two-year project designed to elicit and describe…

Research efforts to model speech perception in terms of a processing system in which knowledge and processing are distributed over large numbers of highly interactive--but computationally primative--elements are described in this report. After discussing the properties of speech that demand a parallel interactive processing system, the report…

This study attempted to explain the findings of classical studies about young children's classification ability, namely that young children: (1) categorize on the basis of perceptual or concrete properties, (2) classify in a linear, nonhierarchical manner, and (3) use inconsistent criteria for classification. The study further proposed that…

Two experiments were conducted (1) to identify the component processes of language comprehension that draw upon cognitive capacity for their execution, and (2) to determine differences in patterns of resource allocation during integrative processing for good and poor readers. In the first experiment, nine good and nine poor college-age readers…
