Using cross country skiing and snowmobiling as contrasting examples of leisure activity (amusement or recreation), this article shows how to use the tenth book of Aristotle's NICHOMACHIAN ETHICS to help high school students make intelligent decisions on a variety of activities. (JDH)

States that childrens' spatial conceptualization of maps progresses from topological to projective to Euclidean. Provides guidelines for conducting map activities with young children which take account of these and related factors. Recommends block play with verbalization for very young children, followed by mapping of familiar environments. (JDH)

A theorem is given for a property of right triangles. From it, students can deduce significant relations. (MNS)

To evaluate prevalence of perseveration in early search, nine-month-olds were tested on both two- and three-location version of Piaget's AB task. Three principal findings emerged: (1) infants did not show systematic perservation on either location task; (2) they did demonstrate positive search skills; and (3) they searched using similiar methods…

Examines the relationship between development of logical processes required in deductive reasoning and their use by preschoolers, also considering possible explanations for children's deductive reasoning. The relationship of problem content to real-world knowledge and the sequence of presentation of problem types were found to affect the display…

Liberal education, like a scarab, appears simple but is very complex, linking many fields of learning. It impels students to view the critical relationships in their world and enables them to feel, create, and understand, combining the characteristics of each discipline into an ability to understand the world and shape it.

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)
