Article focused on childhood experiences for building concepts which promote the growth of logical thinking and learning about the natural world. (Author/RK)

Games of analysis or logical thinking are important reinforcers of various mathematics topics with children, and here the author suggests some games you might use. (Editor/RK)

This study examines 4-year-olds' ability to search and find a missing object, a complex problem-solving task dependent on remembering events, logically deducing the possible subset of hiding places, and implementing situation-dependent search strategies. Sixty-four children recruited from two day care centers in a small midwestern city searched…

Piagetian research provides the focus of this article in which Professor Thomas C. O'Brien interviews Professor Hermina Sinclair. Aspects of children's thinking that prefigure scientific theory construction are described and the influence of schooling in inhibiting or suppressing a theory-building human tendency is briefly discussed. The…

Two studies designed to analyze the role of reflection in logical deductive reasoning were conducted. (Editor)

This study of the understanding of the words "and" and "or" in children, ages 2-7 1/2, indicates that "and" is used to express enumeration, and "or" to express alternatives, and that most children's responses are correct at age 4 and beyond. Differences between the linguistic and logical meaning of connection are discussed. (Author/LLK)

The ability to make relational discriminations, i.e., to solve problems by responding to the relationships between cues rather than to the absolute properties of individual cues, is examined. The laboratory analogy of this type of problem is referred to as a conditional discrimination problem. Mr. Grogg empirically demonstrates the difference…

The purpose of the study was to determine whether kindergarten children could perform successfully on Piagetian class inclusion tasks and whether their performance was a function of the types of conditions under which the task was presented. Children were asked to classify items based on a physical attribute not visually perceptible (painted…

The primary aim of these five technical papers is to indicate aspects of proof theory which may be of use in the study of non-numerical computing. The three main papers are entitled: "Checking of Computer Programs;""Consistency Proofs and Programs for Translators;" and "Experiments with Computers on the Complexity of Non-numerical computations."…

This study was designed to serve several purposes: (1) to determine the level of logical thinking in first term college freshmen of both sexes; (2) to find if their level rose during the first year and especially if it increased as a result of brief intervention aimed at raising the level; and (3) to examine the relationship between logical…

When H. M. Johnson argued that all inductive reasoning is based on the fallacy of affirming the consequent and cannot therefore establish the 'truth' of scientific hypotheses, he posed a paradox for strict empiricists. Author examined Johnson's argument. (Editor/RK)

Five experiments were performed in the area of children's causal reasoning to validate a previously reported developmental difference, to examine the role of a possible mediating mechanism, and to test a number of competing theoretical interpretations. (GO)

This study attempted to clarify the developmental progression in the understanding of conditional sentences by evaluating the capacity of 71 third, 70 sixth, and 64 ninth graders to learn three interpretations of abstract conditional sentences. (JMB)

Describes ten types of analogies and the role they play in thinking and learning. Devotes specific attention to the use of analogies in geography instruction. Claims that the use of analogies in teaching physical, cultural, and regional geography helps students absorb knowledge quickly and integrate it into their existing frameworks. (JDH)
