Although many studies have described adolescents' sexual behavior and attitudes, there are little data available on the nature of the questions that occur to adolescents as they move toward maturity. A study was conducted to determine whether the questions children and adolescents ask reflect developmental differences in cognitive abilities and…

The central aim of this monograph is to stimulate discussion, both of the assumptions that are made about what makes one teacher more effective than another, and of the actions and decisions that are taken as a result of these assumptions. Organizationally, the monograph: (1) presents a brief overview of research on teacher effectiveness; (2)…

Recently, young children have been allowed to testify as competent witnesses in courts of law and the testimony of a single child can be very important in sexual abuse cases. A study was conducted to examine the accuracy of nursery school children's eyewitness accounts in a naturalistic setting. Nursery school students (N=31) viewed two women, one…

A study examined the developmental nature of early literacy in relation to variations in task demands, general cognitive development, and socioeconomic background. Subjects (N=32) were placed in two groups of 16 suburban Chicago kindergarten students that were designated either low income group (LIG) or high income group (HIG). The subjects,…

Writing across the curriculum, or "writing-as-learning" (WAL), represents one of the most successful developments in writing instruction. WAL is an efficient teaching method for achieving educational goals in today's society because it effectively engages students in both the means and the ends of their education. Research has shown that…

The processes of photosynthesis and respiration are basic to the understanding of many other aspects and functions of biological systems. Because of their curricular significance, these processes served as the focal point in an investigation of student conceptions and instructional effectiveness. In this study, students in a college nonscience…

This paper presents research on a theoretical approach to Logo as a programming language that creates a context for learning in which the process by which children learn and develop, using computers, is of greater interest than the products, or outcomes, of learning. Concerned with the cultural context of Logo learning and principles upon which it…

Developmental changes leading to mature judgments of the relative effectiveness of verbal memory strategies were examined in 60 subjects (20 each from second-, fourth-, and sixth-grade classrooms). Subjects viewed videotapes of a female child who was given the task of remembering a set of categorizable pictures. Demonstrations of four memory…

Theory and research on bilingualism and its relationship to cognitive development have provided mixed results, especially in relation to the value of United States bilingual education programs. Little of the existing research on bilingualism is generalizable to U.S. minority language groups. However, one study of children in a bilingual program…

Misconceptions associated with the origins of force and the effectiveness of a bridging strategy for developing correct conceptual models in mechanics are identified for high school physics teachers in this paper. The situation investigated was whether a table exerts an upward force on a book. Student misconceptions related to this phenomenon as…

The cognitive learning processes of assimilation and accommodation are critically examined in this paper. A special focus is given to an analysis of the process of assimilation as it is proposed in Hugh Petrie's book, "The Dilemma of Enquiry and Learning." Initially, Piaget's biological metaphor of assimilation-accommodation is reviewed…
