Recent research suggests that knowledge is stored in the learner's head as a network of concepts or constructs. Children's mathematical problem-solving strategies become increasingly abstract as they are able to engage in more abstract thinking. An experimental study using an alternative Cognitively Guided Instruction approach is described.…

Describes a model for generative teaching of comprehension that focuses on students' knowledge base and preconceptions; motivation; attention; and generation of new models and explanations. Generative teaching procedures for facilitating comprehension in elementary school are reported. (Author/LB)

Describes a science methods course for elementary education majors in which students investigated the phases of the moon. Concludes that students did not make direct connections between their science learning activities and the nature of science. Provides a set of recommendations related to the nature of science and moon study. (Contains 27…

This paper examines research studies that have concluded that elementary school children can learn more difficult and abstract social studies concepts than are taught in the traditional social studies curriculum. Research studies that focus on constraints on cognition, the use of embedded concepts, and understanding knowledge restructuring and…

Presents a study in which the conversations of primary school groups were collected in a botanical garden and analyzed for content. The data were examined for the effects of the presence or absence of an adult in the group, age, and the sex of the pupils. (Contains 27 references.) (Author/DDR)

After a review of the literature on cognitive "cause maps" in organizational decision-making, this study describes a midwestern elementary school from the perspective of individual sensemaking, captured through individual cognitive maps of cause-effect relationships. Data were collected with an adaptation of Bougon's (1983) Self-Q…

Describes the characteristics of progressive schematization with regard to column multiplication and column division. Contrasts this with column arithmetic based on progressive complexity. Presents a summary of research data concerning column arithmetic. (TW)

Discusses theories of how children represent the environment in their memory with reference to recent empirical evidence. States that children are more competent at recalling a route than has been assumed previously and that there are age-related differences in children's ability to select landmarks along a route. (Author/CW)

Conceptual obstacles which inhibit scientific understanding are examined in this monograph. Perspectives are offered on theoretical aspects, research directions, and educational implications on the problem area known as the critical barriers phenomenon. Papers included are: "Nature of the Problem" (by David Hawkins), which describes the…

Describes how an eight year old devised a part-whole schema during a school mathematics process involving the development of a geometric model to conceptualize fractions. Provides examples that utilize this schema in dealing with the relative size of fractions, as well as addition and subtraction, multiplication, and division of fractions.…

This booklet profiles five elementary school teachers who were selected as the 1988-89 Laboratory Fellows by the Regional Laboratory for Educational Improvement of the Northeast and Islands. The Teacher Recognition Program conducted through the Small Schools Network of the Laboratory seeks to recognize outstanding teachers of thinking and…

Focuses on the language used by elementary mathematics teachers and its relationship to students' understanding of mathematical concepts, as well as their misconceptions. Describes eight situations in which the use of precise, formal mathematical terms could be replaced by informal language, particularly when introducing new concepts. (TW)

Traces change in conception of gravity in a boy from kindergarten until second grade, focusing on the process by which persons restructure ideas that differ from accepted scientific understandings, and acquire scientific ideas. Provides criteria for defining an alternative conception; suggests how conditions in the initial interview may have…

This paper describes the BUD project which surveyed childrens' conceptions of division, and of fractions and decimals. The lack of connection between counting skills and conceptual understanding is discussed. The expectations for new algorithms and the basic idea in planning the BUD project are summarized. Some previous studies on counting, the…

Asserts the function of narrative as a method of thinking is important in the lives of children as well as adults. Maintains that, by examining a story or narrative in children's art, it is possible to account for its importance in their lives. Describes three aspects of narrative: (1) invention; (2) description; and (3) negotiation. (CFR)
