Describes one teacher's reflection concerning the quest to develop an understanding of school mathematics that promotes and sustains students' opportunities for exploration and conjecture. Recounts that a particular student's exploration of the features of parabolas eventually led to an understanding of the quadratic formula precisely because of…

Discusses area models that can be used in grades three through nine, showing how the model generalizes from discrete situations involving the arithmetic of whole numbers to continuous situations involving decimals, fractions, percents, probability, algebra, and more advanced mathematics.

Compared the performance of two groups of subjects on psychoeducational tests taken during adolescence and early adulthood. Adolescents who had received a protein supplement when they were infants scored higher on tests of knowledge, numeracy, reading, and vocabulary and showed faster reaction times in information-processing tasks than adolescents…

Presents computer approach formulated within a framework of versatile thinking designed to overcome obstacles to understanding algebra. Results from related studies comparing the computer and traditional approaches taught to 11, 12, and 13 year olds showed that the computer approach significantly improved the understanding of higher order concepts…

This study compared the effectiveness of teaching multidigit addition of whole numbers without regrouping prior to teaching it with regrouping to teaching multidigit addition with and without regrouping simultaneously. Pretest/posttest-delayed posttest results of second grade students (n=151) from seven randomly assigned classrooms indicated no…

Assessed first and third graders' and undergraduates' knowledge of strategies appropriate to comprehension and memory. Also assessed their knowledge of task variables affecting comprehension and memorization tasks. Only undergraduates showed understanding of comprehension-memory distinction. Third graders showed some understanding of differential…

This article reports on the findings of a study involving intensive interviews with 21 former drug addicts who had successfully maintained abstinence for periods ranging from one-and-a-half to four years. They were among the 74 successful former drug addicts out of a pool of more than 2,000 participating in a major rehabilitation program in Hong…

"Educating the Human Brain" is the product of a quarter century of research. This book provides an empirical account of the early development of attention and self regulation in infants and young children. It examines the brain areas involved in regulatory networks, their connectivity, and how their development is influenced by genes and…

This project sought to focus on elements of critical thinking and reflective judgement specific to the college classroom experience using the Reflective Judgment (RJ) Model developed by P. M. King and K. M. Strohm-Kitchener. The project included an exploration of college instructors' assumptions and beliefs about college students, and an…

To examine the skills and knowledge children use when they develop and tell stories, this study sought to provide an experiential demonstration of how schemata guides comprehension. Subjects were preschool, third-, and fifth-grade children described by their teachers as having average reading comprehension. Each child met with a researcher in an…

Using the tools of systematic grammar, this case study examined 3- and 4-year-old children's experiences with storytelling and the potential effects of those experiences on the children's future success in learning to read. Subjects were students attending one of two nursery school classes held at a large primary school on the south coast of…

One hundred seventy-one middle school students participated in a study to assess cognitive activity during television viewing. Students completed a questionnaire about their favorite programs, viewing habits, and social reality beliefs, then viewed a 17-minute professionally edited episode of a family drama and answered a multiple choice…

Abstracts of 11 mathematics education research studies are provided. Each abstract is accompanied by the abstractor's analysis of or comments about the study. Studies reported include: "The Importance of Spatial Visualization and Cognitive Development for Geometry Learning in Preservice Elementary Teachers"; "Classroom Ratio of High…

This paper examines sixth-grade children's thinking related to solving ratio and proportion problems before these children had received any instruction in the domain. It explores unitizing and norming, one of the processes identified by both content analyses (Behr, Harel, Post, & Lesh, 1990); Harel, Behr, Post & Lesh, 1990) and research in…

Schools tend to have a built-in bias toward left brain activities (tasks that are linear and sequential in nature), so the introduction of right brain activities (functions related to music, rhythm, images, color, imagination, daydreaming, dimensions) brings a balance into the classroom and helps those students who may be right brain oriented. To…
