This paper provides an instrumental account of precalculus students' graphical process for solving polynomial inequalities. It is carried out in terms of the students' instrumental schemes as mediated by handheld graphing calculators and in cooperation with their classmates in a classroom setting. The ethnographic narrative relays an instrumental…

Moral sensitivity is the first component of the 4-component moral action process (J. R. Rest, 1986). The author reviews moral sensitivity operationalization and measurement across multiple samples and domains. She reviews 3 definitions of the construct (i.e., "recognition and affective response, recognition, and recognition and ascription of…

This paper considers mathematical abstraction as arising through a natural mechanism of the biological brain in which complicated phenomena are compressed into thinkable concepts. The neurons in the brain continually fire in parallel and the brain copes with the saturation of information by the simple expedient of suppressing irrelevant data and…

In this article, the author describes her attempt to develop more interactive mental mathematics sessions. She observed that her students perceive the multiplication tables as a series of facts which are either known or not known, not as tools which could be used to derive other facts in a flexible manner. She therefore undertook the task of…

Research both in cognitive psychology and psychobiology suggests that political behavior is often less rational than individuals believe it to be. Information processing, memory, and decision making are interlinked processes. Studies in cognitive psychology reveal that even though decision making requires rationality, individuals often adopt…

Discusses the impact of role playing on the change of moral judgment maturity in 96 college students. Subjects showed both immediate and delayed increases in moral judgment maturity when role playing a moral dilemma against an opponent who employed reasoning above the subject's initially assessed state.

The course of study described in this book aims to enlarge the normal purview of literary study to include the subjective cases and purposes for reading and coming to literary judgments. Although the sequence of the four phases in this study should be maintained, the time spent on each phase may last a semester, a year, or longer. The four phases…

Reading is defined operationally as the cognitive process of perceiving and ordering our environment. As such it is a psychomotor process involving the reorganization of experiences evoked by some stimulus. Thus defined, reading is equated with perception and has several primary functions, including concept building, which begins with perception…

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…

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 compared the behaviors of children who had been in a toddler day care program at least 13 months with children who had been there less than 6 months. The children who had been in the program longer were rated significantly higher in ability to get along with peers, problem solving, ability to abstract, and ability to plan. (JMB)

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)

The study with 30 five-year-olds and 30 seven-year-olds demonstrated that children as young as five have an emerging ability to solve both verbal and perceptual proportional analogy problems and to detect the meaning of proportional metaphoric sentences. (Author/DB)
