Reports on the use of a non-traditional approach to constructing a geological timeline that allows students to manipulate data, explore their understanding, and confront misconceptions. Lists possible steps to use in engaging students in this constructivist activity. (DDR)

Presents a part of a larger study attempting to retrieve the versions of the child implicit in the everyday life of a literature classroom. Focuses on a children's novel, "Magpie Island" (Thiele, 1974), and the classroom talk about that novel. Findings reveal that the version of the child implicit in the novel and that enacted in the classroom…

Advocates practitioner-research, by teachers and learners, in their own language classrooms. Points out that teachers who are successful at integrating an investigative element into their teaching may demand collegial support to increase the chance for satisfactory research and that other teachers may develop a new professional concept of what…

Focuses on student modeling within an Intelligent Tutoring System. Describes three domain-independent properties that the formalism representing student knowledge and the processes synthesizing this knowledge must possess to build accurate student models for second-language learning. Notes when, how, and where hypothetical reasoning mechanisms…

College students (N=135) were presented with novel, ill-defined problems and asked to select concepts they thought would help solve the problems. The use of concepts organized around long-term goals was positively related to indices of solution quality and originality. (DB)

Studied the informal knowledge of 36 seven-year-old children of a variety of physical angle situations represented by physical models. Children had an excellent knowledge of all the situations presented, but specific features of each situation strongly hindered recognition of the common features that define the angle concept. (SLD)

Studies whether Piagetian reasoning, general intelligence and achievement motive tap different mental structures, and the relative importance of these measures for concept attainment in physics. Concepts chosen for the study were force, couple, total internal reflection and atom. Results indicate that proportional reasoning, combinatorial…

Discusses the success myth and the American multicultural heritage and education's unintentional perpetuation of this myth. Argues that the roots of this misconception are found in most white educators' failure to understand the differences between the immigration of white Europeans and the forced immigration of Africans. Society's assimilation…

Two experiments examined how 5- and 10-year-olds revised their category representations when exposed to exemplars that were congruent or incongruent with existing knowledge. Findings indicated that judgments about feature co-occurrent within the learned category were influenced by both stereotypical beliefs and exemplar observation. Stereotypical…

Compares concepts defining Kohlbergian stages of moral development with those associated with orders of hierarchical complexity determined with a generalized content-independent stage-scoring system. Finds that Kohlberg's sequence generally matches that identified with the scoring system and that contract and authority concepts match the concepts…

Examines the levels of geometric reasoning commonly exhibited by primary school students, namely visualization, analysis, and informal deduction. Describes open-ended tasks that can be conducted in small groups or in a whole group setting. (KHR)

Describes a number line activity based on students' individual timelines to help students understand the concepts of integers and rational numbers. Middle school students and their parents construct a number line using positive and negative rational numbers to represent dates of events before and after the student's birth. (KHR)

Presents classroom vignettes in which middle grade students with developmentally different views of geometry stimulate each other's reasoning by externalizing mental images through modeling and discourse. (KHR)

Describes how to use common dice numbered 1-6 for simple mathematical situations including probability. Presents a lesson using regular dice and specially marked dice to explore some of the concepts of probability. (KHR)

Suggests that the construction and reconstruction of meanings by learners requires that they actively seek to integrate new knowledge with knowledge already in their cognitive structure. Concept mapping has been used effectively to aid meaningful learning with resulting modification of student's knowledge structures. Asserts that new computer…
