This document reports on a study into the relationships between cognitive preferences, achievement, and ethnicity of first year algebra students. The sample consisted of 175 students from two high schools in the Denver (Colorado) metropolitan area. The two schools were chosen because of the diversity of ethnic groups in the student populations.…

An analysis of children's narrative composition and art revealed concurrent development at both a general structural level and at a fine-grained detail level. A three-part study investigated whether this general cognitive pattern would be maintained across a different range of tasks: literary composition, scientific reasoning, and working memory.…

The problem beginning secondary school teachers face in bridging the knowledge gap between the subject discipline studied in college and the content that must be taught to high school students is analyzed in this study. To demonstrate this problem and follow the progressive steps taken to partially solve it, case studies are presented of two…

This paper contends that efforts at educational reform must focus, above all, on the instructional encounter between teachers and students. The argument is presented in triadic sequence: three basic assumptions about learning, three interrelated models of the instructional process, and three practical approaches to promoting cognitive achievement.…

Explores three aspects of temporally displaced talk between mothers and children: (1) the role of the knowledge base in such talk; (2) the effect of mother talk on child talk; and (3) the impact of such talk on the child's knowledge base. Indicates that maternal speech can mediate information and experience and contribute to the child's world…

Proposes a framework for interpreting current research in science education. Presents four prototypes for describing research which are derived from comparisons and combinations of "spontaneous" and "formal" knowledge. Discusses possible applications of the use of the framework in science education. (TW)

Provides information about the curriculum characteristics of first- and third-year high school Spanish textbooks and determines what differences exist among the texts involved. Study results indicate that these textbooks are consistently "deficient" on nearly all of the dimensions examined. (Author/SED)

This study addresses questions about particle physics that focus on the nature of electrons. Speculations as to whether they are more like particles or waves or like neither illustrate the difficulties with which students are confronted when trying to incorporate the concepts of quantum physics into their overall conceptual framework. Such…

This paper discusses the establishment of a connection between cognitive concepts and knowledge acquired through English-as-a-Second-Language teaching and learning. Modern thinking focuses on effective application of common global knowledge and language skills appropriate for culturally diverse students. The article suggests that a cognitive…

Discusses politeness strategies used by native and Dutch speakers of Spanish, contrasting the act of making requests by these two groups of speakers. One of the article's conclusions states that native speakers of Spanish are more direct in their requests, and that nonnative speakers attempt to sound less face-threatening and less offensive. (23…

Introduces recent trends in international development cooperation. Argues that applying these trends to information and communications technologies (ICTs) would make them more effective, empowering, and efficient. Presents current strategies of the International Institute for Communication and Development to illustrate applications of these…

Investigates commonsense knowledge schemes connecting the elements weight, air, and gravity to the phenomena of free fall of a range of students from primary school children to adults. Finds that majority of people from the secondary education level onwards held alternative schemes. Discusses educational impacts of mass media. (Author/YP)

Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…

Maintains that children's ability to understand and use narrative precedes their ability to understand and use other genres. Asserts that the link between history and narrative is overlooked in discussions about children's historical understanding. Argues that children should use narrative. (CFR)

Reports the rationale, design, validation, and uses of the "Force Concept Inventory," an instrument to assess the students' beliefs on force. Includes results and implications of two studies that compared the inventory with the "Mechanics Baseline." Includes a copy of the instrument. (MDH)
