This paper focuses specifically on the reasoning skill called proportional reasoning. Areas addressed include: (1) a definition (providing examples of direct and indirect proportional reasoning); (2) the development of proportional reasoning (discussing survey results of students logical reasoning abilities); (3) planning for the future (proposing…

Noting that a distinction can be made between the different types of problems faced by managers in today's organizations, and that managers increasingly face problems of a more complex nature, this paper suggests that an interactive management approach is best for solving complicated problems. Following an introduction that distinguishes between…

Noting that the media can be powerful instruments in the hands of creative teachers, this paper explores the use of media as instructional tools to promote growth in thinking and language processes (primarily reading and writing). The paper views media form and applies it to the interrelationship of experience, thought, and language. It proposes…

Prompted by current theories in reading suggesting that variation in word knowledge affects the processing of not only individual words but also clauses and sentences, this report explores some different ways in which children's comprehension processes may be affected by variation in word knowledge. The report first examines whether the effects of…

Models of well being and human functioning have traditionally been based on empirical studies done with children and young adults. As part of an ongoing research program to develop and test a model of effective functioning and positive health in older adults, 31 elderly individuals (7 males, 24 females), with a mean age of 73.58 years, completed…

Some central issues in discussions of creative processes in science are: (1) the mechanism(s) by which hypothesis formation takes place; (2) the sources of new knowledge during hypothesis formation; and (3) the "Eureka" versus steady accumulation (accretion) issue concerning the pace of change during hypothesis formation. This paper…

The heuristic model and measurement models guiding a proposed seven-year investigation of how children learn to comprehend what they read--and in particular how they comprehend science text--are described in this report. The report first offers a brief description of the heuristic model, which is based upon and extended from studies of effective…

After students recommended books by M. E. Kerr, such as "Is That You, Miss Blue?" and "Dinky Hocker Shoots Smack," a college teacher realized that Kerr's books contained memorable characters and were suitable for classroom use. Particularly useful was Kerr's 1983 nonfiction book, "Me, Me, Me, Me, Me," which recounts…

Within the framework of a general model of communication, a model of language communication has been developed and applied to the perception of cohesion. To measure students' perception of textual cohesion, a pilot study in the United Kingdom built "noise" into texts by deleting parts of each texts. Subjects, 59 nonremedial students whose first…

Previous studies were conducted with 14- to 15-year-old students on the nature of the processes they used to solve tasks given the incorrect/buggy/mal-rules. The computer-based Leeds Modelling System (LMS) was implemented and a database of examples, correct and incorrect, or mal-rules had been established which was sufficient to diagnose the…

Although the listening construct has been defined more widely in order to deal with the issue of lecture retention, these wider definitions suffer from serious conceptual and methodological problems, such as the assumption that receiving behavior is the same regardless of differing situations and messages. However, the literature would indicate…

Noting that the problem of writer's block is often rooted in such cognitive difficulties as rigid or inappropriate composing rules and planning strategies, this study approaches writer's block as a measurable problem that can be analyzed and remedied. The introductory chapter defines writer's block and pertinent terms, discusses a cognitive model…

Recent research on solving addition and subtraction word problems has resulted in the construction of theoretical models of children's problem-solving processes. Some of these models have been translated into computer programs. Characteristics and predictions of the theoretical analysis developed by Riley, Greeno, and Heller (1983) are discussed…

Discourse comprehension involves readers or listeners in constructing mental models using local text information, global text structures, and their general knowledge of the world. An analysis of the literature on children's understanding of spoken discourse reveals that young children are capable of forming mental models from texts, but that their…

A framework for a comprehensive theory of reading is presented in this paper. The framework consists of perceptual, semantic, and control systems. The perceptual and semantic spaces of the theory should not be confused with the terms "decoding" and "comprehension"; decoding and comprehension refer to ways in which those spaces…
