A unidimensional latent trait model was used to test a single-factor hypothesis of the Lawson Classroom Test of Formal Reasoning. The test failed to provide a valid measure of formal reasoning. This was a result of test format which neglected aspects of formal reasoning emphasized by Inhelder and Piaget. (Author/DWH)

Investigates several variables' effects on children's inferential processes, including cause of target event, presence and timing of questions prior to recall, and inference type that the questions demanded. Children four and seven differed in logical, constrained, and unconstrained inference production; causal connections between story events…

Ordering theory was used in two studies to empirically determine hierarchies of developmental precedence for Piaget's 16 logical combinations. In study 1, subjects (N=94) responded to statements about odd and even numbers; in study 2, 30 subjects responded to statements about line segments. Results are reported and discussed. (Author/JN)

Because university teachers tend to be intellectually lazy and avoid sound, rigorous thought, it is emphasized that they should weigh evidence, assess arguments fairly, and take a partial stand on values and philosophies they hold. (ND)

Concludes that the role of the teacher as researcher in children's development of thinking and socialization through play is multi-dimensional. The initial function is the internal analysis of children's thinking and interaction within a variety of settings. (Author)

A formal theory of human understanding was developed and embodied in a computer program, UNDERSTAND, which simulates the understanding processes. Due to the number of alternative processing choices, some assumptions were made which are analyzed based on their validity. (Author/DEP)

The authors examine the literature that sets the foundation for a self-actualization model for teacher induction. The model is analyzed in light of data from a successful induction program designed to keep special education teachers in the profession. (Contains 1 table and 1 figure.)

This paper suggests that logic consists of a collection of propositions and operations of negation, conjunction, disjunction, implication, and equivalence. It points out that the operations on dispositions depend upon the truth-value of the propositions involved. This raises the questions, How do we know whether a proposition is true or false? and…

Develops a new version of debate case form. (CH)

Deaf children, seven to thirteen years old, were observed on concrete, transitional and formal operational tasks ranging from dual classification to combinatorial reasoning. Results were related to number of years of schooling. (ST)

Study lends support to the view that the problem with left-right stems from the imperfect mastery of the basic discrimination, not from an inability to deal with the logic of relational concepts. (Author/CB)

An analysis of critical thinking is discussed in terms of conceptual interpretations and through determining the logic of linguistic expressions. (Author/RK)
