This study hypothesized that subjects who display proportional responses on the Pouring Water Task have developed the ability to comprehend logical arguments of the form referred to as "reasoning to a contradiction," while subjects who display additive responses on the same task have not. To test this hypothesis, 100 additive and…

Since a discourse community may have its membership assigned both on the basis of speech or of writing, it follows that the concept of discourse community needs to be both medium-neutral and unconstrained by space and time. The defining characteristics of a discourse community might be (1) communality of interest, (2) mechanisms for…

Research involving cognitive modification and using intervention instruction in general prerequisite cognitive processes has shown that significant and long-term results are possible. Use of intervention instruction involving prerequisite data gathering skills with teachers has been successful in improving ability to use probing questions in…

Comprehension of metaphor was examined in 36 children ranging in age from 55 months to 186 months. The subjects were audiotaped while answering questions about a target sentence that was contextually anomalous. Five pictures were drawn to accompany each story, two relating to the literal meaning of the target sentence, two to the metaphoric…

Civil liberties are rights enjoyed by individuals guaranteeing them protection from the arbitrary or discriminatory acts of government. Kohlberg's cognitive-developmental theory of moral reasoning and studies of behavioral/abstract attitudinal measures provide a rationale for examining moral reasoning processes, intelligence, and selected…

This paper discusses the theoretical problem of matching and abstraction of concepts as the processes occur in human minds, and the structures used to represent these processes for use in automated, knowledge based systems. A basic premise of the paper is that hierarchies play a crucial role in structuring knowledge and in solving problems. Data…

The purpose of this research was to assess the validity of recent claims that experimenter-provided pictures facilitate young children's oral prose learning. The major question of interest was whether the pictures do nothing more than prompt the child to process the just presented information one more time, Three experiments were designed to test…

Investigated, within a Piagetian framework, was the degree of abstract preferences exhibited by five different grade levels of science students as they completed eighteen problem solving tasks. Three hundred twenty-nine randomly selected students from five grade levels, ranging from eighth grade to college seniors, were given the Shipley Test of…

We examine eight cases of argumentation in relation to a proportional reasoning task--the "Paint" task--in which the "constant sum" strategy was a significant factor. Our analysis of argument follows Toulmin's (1958) approach and in the discourse we trace factors which seem to facilitate changes in argument. We find that the arguments of "constant…

This paper reports on methods of students' justifications of their solution to a problem in the area of combinatorics. From the analysis of the problem solving of 150 students in a variety of settings from high-school to graduate study, four major forms of reasoning evolved: (1) Justification by Cases, (2) Inductive Argument, (3) Elimination…

This study explored the moral reasoning and scientific argumentation skills of 31 gifted Finnish adolescents participating in a science program at the University of Helsinki. Students were given the Defining Issues Test (DIT) to determine their level of moral reasoning and the Raven test to evaluate their scientific reasoning. The argumentation…

The purpose of this paper is to review literature on analogical reasoning, to work out the implications of Polya's model of analogical problem solving, and to propose an alternative model of instructional design based on the use of analogical reasoning. Justification of the model is based on research on the nature of analogical thought and an…

A study involving 120 undergraduate students attending the University of St. Thomas in St. Paul (Minnesota) was undertaken to test the interactive effect of instructional strategy (structured versus constructed) with learner's prior domain knowledge in concept acquisition. Previous instructional design research on concept learning has focused on…

A research project explored the idea that reasoning develops in distinct phases of thinking as individuals journey from simplistic learning of facts to highly proficient consequence predicting of integrated relationships. These results were derived from a study that examined the thinking processes and problem-solving actions of 13 students and…

Working on the hypothesis that if readers had several alternative correct meanings of a given text set before them they would select the one in accordance with their abstract abilities and intellectual maturity, a study investigated the measurement of levels of meaning as illustrated in taxonomies and focused on the applicability of the taxonomies…
