Reports on a preliminary project that uses a phenomenographic approach to explore the ways in which a small number of fundamental ideas are conceptualized by students who are judged to have mastered quantum mechanics material. (DDR)

Investigates the mental models that people construct about magnetic phenomena. Involves students, physics teachers, engineers, and practitioners. Proposes five models following a progression from simple description to a field model. Contains 28 references. (DDR)

Seeks to identify some of the issues associated with the role of models in scientific explanations. Discusses factors which may influence the way that those explanations are understood and the judgment of their appropriateness by the various audiences involved. Contains 55 references. (DDR)

Examined whether infants believe that size of a moving object striking a stationary object will affect how far the stationary object is displaced. Found that the infants did believe the size of the test cylinder affected the length of the test object's displacement and that they used the initial familiarization event to calibrate their predictions…

Considers individual students' progress as they use tools, discuss data distributions, and interact with teachers and their peers. Suggests that data display tools provide a partial context for discussions but do not constrain the students' interpretations or the way they reason about the data. (Author/MM)

Describes a methodology for analyzing the collective learning of the classroom community in terms of the evolution of classroom mathematical practices. In developing the rationale for this approach, grounds the discussion in work of mathematics educators who conduct classroom-based design research. Frames sample analysis as a paradigm case in…

Examined how student's strategies and associated conceptions emerged and changed over a 6-session tutoring curriculum designed to develop conceptual knowledge of linear functions. Found that the student did not erase his original conception or replace it with a conception supported by instruction, but instead refined his initial strategies and…

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 book discusses the act of understanding in mathematics. The first chapter, "Understanding and Meaning," inquires into the various senses and uses of the word "understanding" in ordinary language and discusses the notion of meaning and relations between understanding and meaning. The second chapter, "Components and…

The role of planning in the design of digital circuits was studied in two experiments. One compared the planning-related activities of expert designers and beginning students of design, and the other looked at the effect on circuit-design processes of forcing students to construct a global plan. In experiment 1, five undergraduate students…

The research described in this paper leads to an instructional design approach which is an alternative to the consideration of such issues as mathematical skills or level of cognitive development. The approach uses an analysis of traditional instructional tasks to specify the underlying cognitive processes and structures necessary for the…

Explores how thinking is organized, drawing upon the development of Darwin's thought from varying time perspectives. The struggle for coherence and identity in theory construction is seen as a dual process: that of an intutitive contact with the material and an abstract purposefulness and perspective. (Author/AM)

This article is a commentary on TM 501 927 by the authors of the study "Classification and Seriation Instruction and Logical Task Performance in Preschool." (DEP)
