An integration of "systems" and "synectic" approaches and an unconventional use of role-playing are salient features of the problem solving workshop, looking for fresh approaches to the improvement of undergraduate education. (JH)

Describes two exercises which demonstrate to students the mechanics involved in arriving at logical conclusions. (BR)

Examines the effects of principle of inference, relatedness of content, and mode of test presentation on the development of the conditional reasoning abilities of primary-grade children. (Author/SDH)

This study examines the ability of 20 5- and 6-year-old children to determine whether an inference could reliably be made or whether a problem was undecidable. Children were given a random series of 8 decidable and 16 undecidable problems in which they had to determine in which of 2 houses a target character could be found. There were two…

In their efforts to understand the grammar of English as a second language, students often confuse the two roles that grammatical elements play: form and function. A classroom technique for helping students distinguish between the two is to create playful analogies for specific structures, in which students must use reasoning to determine the form…

In an experiment using a conditional logic task, subjects were given a set of cards defining a particular conditional relationship. The subjects were required to determine the rule and predict the outcomes of the rule. Rule structure was varied by providing subjects with either a suggested rule, a partial rule, or no rule for each set of cards.…

Scholars have long been interested in the relation between rhetoric and dialectic. Recent theorists suggest that one way of viewing argument is through the perspective of argument-as-procedure, in which rules such as those attendant to the conduct of dialectic, debate, or discussion come under the purview of argumentation. This paper is a critical…

This paper contains an elementary and short proof for the case that the underlying distribution function F is discrete, and then extends the result to the general F. In other proofs underlying iid sequences of random variables with continuous distributions are considered to be the "ideal" case. In this paper discretization of the underlying iid…

The purpose of this study was to determine whether relationships occur among spatial skills, logical reasoning, and various genetic concepts. Twenty-one students enrolled in an undergraduate genetics course in a northern New Jersey institution completed a series of tests and tasks designed to measure flexibility of closure, visualization,…

The teaching of critical thinking requires an understanding of the term, defined in this document as the processes of judgement or evaluation. Informal logic teaches students to understand and analyze arguments which are fallacious, to determine what is valid and invalid, and to evaluate non-deductive arguments. John McPeck and Richard Paul…

This technical report has two purposes. One purpose is to present an end product of a multi-year research investigation into the cognitive skills involved in performing intelligence analysis. The product is a "Handbook for Strategic Intelligence Analysis" developed for the United States Army Intelligence and Threat Analysis Center…

The spontaneous use of analogies in problem-solving occurs when a subject first spontaneously shifts his attention to a situation (B) which differs in some significant way from an original problem situation (A), and then tries to apply findings from B to A. This paper describes research on the process with 10 scientifically trained subjects…

This paper describes the development and characteristics of structural interview procedures designed to aid researchers in investigating children's understanding of their logical arguments. The procedures comprise a system which assesses verbal expression, understanding of implication, and ability to reason logically; it also assesses…

This study looked at preschool and first-grade children's ability to draw script-based and text inferences in comprehension of stories they heard. In two experiments, children were asked to recall brief stories and answer two inference questions: one script inference question requiring them to fill in information about the event that was not…

Article considered the CoRT approach toward education, an approach in which thinking is treated as a broad practical skill that is to be used rather than just learned. (Author/RK)
