Describes an experiment which determined the amount of loss in French skills that students suffer during the summer vacation between grade 9 and grade 10; research supported by a grant from the Ontario Ministry of Education. (RL)

Although there was an increase in the proportion of students using the logical principle of exclusion" from grades 7 to 9 to 12, there was little relationship with IQ and socio-economic measures. (AL)

Performance in cognitive tasks involves two distinct processes; acquisition of knowledge and cognitive control over knowledge already acquired. A conceptual and analytic framework is presented which allows for the disentanglement of knowledge and control, and for the quantification of each. (Author)

Describes the intellectual development stages ascribed to children by Jean Piaget. Characteristics and examples are given for sensori-motor, preoperational, concrete operational, and formal operational thinking periods. Implications are given for elementary school science education, including (1) formal instruction does not accelerate acquisition…

Reviews continuities and discontinuities in the field of developmental psychology between 1970 and the early 1980s, limiting discussion to areas of cognition and learning. Three major theoretical trends are identified: Piagetian, behavioristic, and information-processing. The field is perceived as fragmented, and it is expected that such…

Literature indicating a correlation between age/grade of students and spurt and plateau periods of brain growth is reviewed. Suggestions for teachers based on the review are provided. These include indexing learning and behavior events to brain growth spurt/plateau periods, using spurt times to introduce novel intellectual materials, and others.…

A promising line of inquiry concerning the development and use of formal operations strategies is presented and a number of conceptual and empirical questions are raised. (Author/PN)

The development of probability judgment is explained in terms of working memory, composed of four types of storage operations and three types of processing operations. Age changes in probability judgment were related to changes in frequency retrieval, which stem from changes in constraints on work-space capacity. (Author/RD)

The method presented provides a systematic approach for communicating information about interrelationships between concepts taught in a psychology course. Students who did not receive the information through traditional instructional methods received enhanced scores on tests of structural understanding. Five references are listed. (MER)

Jean Piaget's theory of cognitive development described what children are capable of doing at each stage of development; new research focuses on actual use of these capabilities. (Author/MLF)

An outline of a model that provides a new perspective on the conceptual foundations of mathematics and a new approach for the study of children's acquisition of numerical operations is proposed. Attention is viewed as a pulse-like succession of moments and is supported by recent data from neurophysiology. (MP)

Discusses Piaget's theory of constructivism and its practical application in schools. Gives evidence for the value of constructivist teaching and the importance of offering different kinds of education within the same system. (WD)

Suggests that future pedagogy should search for methods to develop conscious thinking and to connect detailed learning with creative, utility-oriented human activities. Different pedagogical forms should be applied to a greater extent in universities and ordinary adult education. (JOW)

In order to determine if there are developmental effects on information integration and dispositional attributions, 145 adolescents at two ages (13 and 18) were presented with information about hypothetical peers. (Author/MP)
