This book offers a broad view for a varied audience of what the vision expressed in all three National Council of Teachers of Mathematics' Standards documents will look like when aligned with practice and outlines ways in which desired changes can be realized. Six sections and 21 chapters in the book are: Section I--History: (1) "Paths to the…

Various aspects of the cognitive model of physics problem solving are discussed in detail including relevant cues, encoding, memory, and input stimuli. The learning process involved in the recognition of familiar and non-familiar sensory stimuli is highlighted. Its four components include selection, acquisition, construction, and integration. The…

This study examined the relationship between knowledge of sequence relations and the process of mental rotation in four-year-olds. Subjects were 12 preschool children who were tested individually. They were given a State Comparison Task (SCT) in which they were shown pairs of animal pictures, half identical and half mirror images of one another,…

Some experts were asked to summarize what they knew about career development in five short messages. What resulted is the "High Five" of career development: 1) Change is constant; 2) Follow your heart; 3) Focus on the journey; 4) Stay learning; and 5) Be an ally. Each of these messages is briefly described in this digest. Change, in the…

The persistence of the constructivist agenda within learning and developmental theory suggests that underneath the seemingly disparate views of Piagetian, socioculturalist, and ecological perspectives lie some unifying concepts that find their mutual expression in constructivism. The paper contends that semiotics provides the conceptual means to…

This study examines the earliest jokes produced by three children and investigates how these jokes contribute to a model of humor development. Subjects were three male infants, and data was collected through a diary record procedure kept by the children's parents. Data was collected on one child at age 13 months; data collection for the other two…

This study suggests a fifth Piagetian stage and offers empirical evidence in its support. Piaget's traditional fourth stage (formal operations) is operationally defined as the problem-solving stage and the suggested fifth stage as the problem-finding stage. The commonly accepted criteria for a stage model are applied. (JMB)

This article presents an argument, based on psychological research and inferences about human evolution, for the plausibility of an intrinsic altruistic motive. A theoretical model for the development of such a motive is outlined. (JMB)

Children from grades 1, 3 and 5 classified and later recalled 24 pictorial items. It was found that classification, recall and clustering scores increase with age and vary as a function of item category. (GO)

The possible effect of experimenter expectancy in number conservation task experiments was explored. (JMB)

Examined how college-age adults and 8-, 11-, and 13-year-olds retrieve semantic information from long-term memory. Closely comparable results were obtained across ages. This developmental similarity is discussed in relation to developmental differences in the use of semantic information in other cognitive tasks. (JMB)

Boys, ages 6, 8, and 10, were classified with regard to conceptual tempo and were presented with cartoon stimuli varying in cognitive complexity and level of affectivity. The results indicate that reflective subjects generally displayed the highest comprehension scores while impulsive subjects displayed the greatest spontaneous mirth. (JMB)

Two experiments investigated the role of kindergarten and elementary school children's spontaneous cognitive sets in pictorial discrimination learning. Data indicated that, in comparison to the behavior of older children, the behavior of kindergarteners is governed more by the perceptible than by the conceptual attributes of stimuli. (GO)

The present study investigated egocentricity in children and youth. Exner's Self-Focus Sentence Completion (SFSC) was used to measure egocentricity. (Author/RK)

Examined the effects of varying degrees of teacher support on middle-class preschoolers' success in cognitive and motor learning tasks. Support was defined in terms of physical proximity, physical contact, and facial and verbal behaviors. (JMB)
