The paper discusses problems with traditional definitions of dyslexia and reviews research that suggests a more comprehensive definition, viewing dyslexia as a developmental language disorder that involves a deficit in phonological processing. The disorder is seen as manifesting itself in various phonological difficulties as well as in a specific…

The purpose of this paper is to review and synthesize the literature on adult development and to suggest how this information can be applied to the practice of adult education. The first section discusses the nature of adult development, its definition, and key concepts. Sequential patterns of change in adulthood are examined in section 2,…

Reports on a study of young children's abilities to discriminate between two chords played as the accompaniment of a melody and played alone with no melody. Finds that age, type of stimulus, and the interaction of these two variables affected children's performance significantly. (CFR)

This study investigated young children's ability to solve probability problems and studied the cognitive processes proposed by Piaget and Inhelder as necessary to solve probability problems. The effects of tutorial and self-discovery training were measured and discussed. Results from 168 first-graders in five training conditions indicated that:…

Argues that classroom learning inevitably requires adaptive responses by students, and that teachers should deliberately promote the development of students' adaptive learning within a supportive classroom environment by emphasizing the constructive benefits of functional failure and the limited benefits of uninformative success. (SKC)

Twenty-four children (ages 6-9) with mild mental retardation received individualized instruction with either emphasis on Piagetian concepts or emphasis on verbal and number concepts. Although both groups made significant gains over a year, the children receiving the Piagetian emphasis usually gained more and progressed at almost the rate of…

Key developmental tasks of adolescence and the unique problems that face the learning-disabled adolescent are outlined, focusing on the role of social competency and communication effectiveness. Components of a comprehensive social competency training program include the nature of the learning disability, the affective-defensive pattern, adaptive…

Offers a descriptive theory of the nature of classroom tasks. Describes the interplay among (1) the conditions under which tasks are set; (2) the cognitive plans students use to accomplish tasks; and (3) the products students create as a result of their task-related efforts. (SKC)

Reports on a study of the mathematical knowledge, strategies, and representations of 16 socially and ethnically diverse preschool children. Finds that the children bring a wide range of competencies that generally are more advanced than the curriculum content presented at that level. (CFR)

Reports research on teachers' beliefs about children's development. Discusses (1) teachers' estimates of ages at which children succeed on tasks, (2) teachers' ability to engage in task analysis, (3) their view of children's error, and (4) their view of developmental accounts. Concludes that good teachers' beliefs provide an inadequate basis for…

Reviews research about young childrens' focusing on the ability to transform a perceived scene into another representation. Reports on a study of 109 children and 18 college-age students on their ability to mold a lump of clay into a three-dimensional figure. Finds that cognitive maturity alone does not automatically lead to competence. (CFR)

Responds to Claire Golumb's research on the cognitive development of young children's ability to create representations of reality using visual arts. Asserts that young children must find acceptable pictorial substitutes when producing representations. (CFR)
