Cross-grade studies are valuable for the development of sequential curriculum. However such studies are time and resource intensive and fail to provide a clear representation to integrate different levels of representational complexity. Lin (Lin, 2006; Lin & Chiu, 2006; Lin, Chiu, & Hsu, 2006) proposed a cladistics approach in conceptual…

Explores the extent to which student questions are indicative of understanding as well as strategies for encouraging questioning. Student questions are categorized as consolidation questions, exploratory questions, and elaboration questions. (DDR)

Examines the validity of claims that concept maps measure an important aspect of students' knowledge structures. Provides a working definition of concept mapping and a brief theoretical background, characterizes concept maps as a potential assessment in science, reviews empirical evidence on the reliability and validity of various concept mapping…

The challenge to the dominance of rationality in educational philosophy presented by John Dewey and Donald Schon is examined in this paper. The paper identifies basic assumptions of their perspective and explains concepts of reflective thinking, which include biography, context of uncertainty, and "not-yet." A model of reflective thought…

This paper theoretically characterizes number sense as a set of cognitive capabilities for constructing and reasoning within mental models. This perspective provides support for viewing various aspects of number sense as features of students' general condition of knowing about numbers and magnitude, rather than as skills needing specific…

Assesses the understanding that a sample of Oregon public school students (n=159) had of geology, physical and chemical characteristics, ecology, and natural resources as related to a marine environment. Results indicate that student understanding in some areas does not progress beyond the early grades and that the interdisciplinary approach of…

Considers effective dialogue between teacher and student essential for promoting meaningful learning in the classroom. Effective dialogue enables teachers and students to be active in the construction of shared understanding by making explicit the overlap between the perspectives held by students and teachers. Suggests that concept maps provide a…

An alternative is suggested to conventional and propositional ways of thinking about curriculum matters. Curriculum theory is conventionally presented as statements of propositional knowledge even though the significance of tacit, non-propositional knowledge has been recognized in philosophy. It is suggested that attention be paid to how teachers…

This paper presents a critique of current research on functional understanding of thinking and teaching. Three trends in cognitive research are examined. The "reification of mind" (the assumption that "mind" is an entity just as is body) is examined as a research trend that accepts knowledge as existing independent of the biographies, the…

Describes a study that investigated probabilistic intuitions held by students (N=98) from grade 7 through college through the use of a questionnaire. Of the misconceptions that were investigated, availability was the only one that was stable across age groups. Contains 20 references. (DDR)

Presented is an alternative method for analyzing the van Hiele level of students' geometrical reasoning. The accuracy of students' answers may afford a description of acquisition and/or expertise for each of the van Hiele levels simultaneously rather than the traditional assignment and evaluation of one level at a time. (JJK)

Explores the knowledge development of Taiwanese 5th grade students (N=28) of biological reproduction. Proposes three stages of knowledge acquisition based on the results of the study. (Contains 17 references.) (DDR)

This conceptual framework is grounded in the data analysis of transcribed interviews with 50 Ontario teachers and the text of a 7-month online discussion group among 25 principals from England, Ireland, Canada, United States, Australia, and New Zealand. Both methods were employed with the stated purpose of understanding emotional experiences of…

Aims to quantify the models that 13- and 14 year-old students hold about the causes of the greenhouse effect and ozone layer depletion. Assesses the prevalence of those ideas that link the two phenomena. Twice as many students think that holes in the ozone layer cause the greenhouse effect than think the greenhouse effect causes ozone depletion.…

Reports research that examines children's models of seed. Explores the conceptions held by children (N=75) of germination and seed formation. Concludes that children hold a restricted meaning for the term 'seed'. (DDR)
