Students' academic achievement scores have been found to improve with the use of graphic organizers. Unfortunately, most previous research on graphic organizers has been constrained to English speakers in secondary and higher education. This study examines the effectiveness of graphic organizers when used by fourth grade students engaged in…

Cognitive flexibility is indispensable for applying knowledge to new situations. The development of this ability depends on certain conditions such as the attainment of a deep comprehension of the subject matter and the exposure to different knowledge representations. This paper focuses on these conditions and describes a study designed to foster…

Multidimensional knowledge structures, described from a constructivist perspective and aligned with the "Mind as Rhizome" metaphor, provide support for constructivist learning strategies. This qualitative study was conducted to seek empirical support for a description of multidimensional knowledge structures, focusing on the…

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…

Explores the promises that von Glasersfeld's constructivism holds for the reform of science and mathematics education. Argues that a powerful social epistemology is needed to serve as a referent for regenerating the culture of science education. Contains 48 references. (DDR)

Examines some of the misconceptions about the nature of critical thinking. Focuses on the characterization of critical thinking in terms of processes or skills and the separation of critical thinking and knowledge. Offers a different conception of critical thinking. (Contains 46 references.) (DDR)

Describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations. Argues that a task-oriented interaction between propositional structures and mental models can help learners evaluate the consistency of their…

Describes a study that explores the instructional influence of presenting pictures at the molecular level when introducing chemistry concepts and solving chemistry problems. Explores the effect of the pictures on students' conceptions and problem-solving abilities. Contains 59 references. (DDR)

Lends support to the idea that the quality of the cases used in problem-based learning affects the nature of student learning in this context. Outlines seven principles adapted from research on learning and cognition that can help guide case design. Contains 22 references. (DDR)

Speculates about reasons for the lack of use of concept mapping as an instructional strategy. Concludes that the two main barriers to its extensive adoption are the epistemological beliefs of classroom teachers and the underlying philosophy of the curriculum. (Contains 45 references.) (DDR)

This paper focuses on the cultural aspects of research in mathematics learning. The shift to a more socio-cultural emphasis in mathematics education research is valid. The paper explores this point by examining challenges to the former research paradigm. These challenges include culturally-based mathematical knowledge and hidden values in…

Focuses on student and in-service primary teachers' learning about balanced and unbalanced forces in a range of contexts and identifies significant features of the learning process from the learners' perspectives. (Contains 33 references.) (DDR)

This paper presents findings from a study that investigated students' understanding of quantum phenomena and focused on how students incorporate the ideas of quantum physics into their overall cognitive framework. The heuristic metaphor of the map is used to construct graphic representations of students' understanding of quantum physics. The…

Maintains that region familiarity is an important prerequisite in the instructional use of cartograms. Cartograms are value-by-area maps that increase or decrease areas in order to illustrate various data (e.g. book reading in the western United States). Discusses necessary cognitive processes for the visualization of data. (MJP)

An administrator's daily life is full of decisions that often involve an "on the spot" solution. This paper discusses some of the principles involved in drawing inferences in research and decision making, and describes how a knowledge of decision-making errors can help administrators. The paper also describes a case study that…
