This research focused on preservice elementary teachers' understanding and reconstruction of understanding about multiplication in the domain of fractions. At the start of the study, 44% of the 50 preservice teachers studied reported that they had a method for reasoning about multiplication with fractions, and 28% were able to describe a situation…

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…

One principal's criterion for proper decision-making information may be much different from that of another. Information providers need to decide what constitutes relevant information when communicating to decision-makers. Fifty-three principals and 11 assistant principals were administered two indicator tests to investigate the relationship…

This paper describes the Structure-Mapping Engine (SME), a cognitive simulation program for studying human analogical processing. SME is based on Gentner's Structure-Mapping theory of analogy, and provides a "tool kit" for constructing matching algorithms consistent with this theory. This flexibility enhances cognitive simulation studies by…

Examines the development of metaphor by using structure-mapping theory to make distinctions among kinds of metaphors. Proposes that children can understand metaphors based on shared object attributes before those based on shared relational structure. Results indicate a developmental shift toward focus on relational structure in metaphor…

Suggests that using Bloom's taxonomy of the six levels of cognitive operations--knowledge, comprehension, application, analysis, synthesis, and evaluation--can help instructors formulate challenging questions which guide students' critical thinking skills. (MM)

Argues that reasoning is not governed by mental logic or models. Proposes new operational semantic theory, in which reasoning is based on children's operational understanding of key terms in a given problem. Reports results of a study of class inclusion in which dramatic differences in performance were found as the result of linguistic context.…

An overarching learning theory is presented, based on assumptions that all learning includes (1) external learner-environment interaction and internal acquisition and elaboration and (2) cognitive, emotional, and social dimensions. The framework depicts four types of learning: cumulative, assimilative, accommodative, and transformative. (Contains…

Argues that teaching writing conventions in a basic writing class is not a sufficient preparation either for the traditional freshman writing course or for the courses in the students' majors that will follow. Argues that students should be provided with appropriate reading and writing activities of real complexity at every level. (RS)

Two experiments examined whether 40 infants would reenact what an adult did or intended to do: (1) infants observed an adult unsuccessfully attempt to complete 4 target acts; and (2) children observed a mechanical device tracing the adults' actions. Infants could infer adults' intentions and imitate target acts, suggesting that children can…

Researchers collected cognitive structure and reflection data from prospective teachers to test whether schemata and reflection, structure, and process were linked. Results indicated a positive correlation between complexity of knowledge structure and reflective ability. The way teachers organized their knowledge of classroom management affected…

Proposes a model for the growth of mathematical understanding based on the consideration of understanding as a whole, dynamic, leveled but nonlinear process. Illustrates the model using the concept of fractions. How to map the growth of understanding is explained in detail. (Contains 26 references.) (MKR)

Presents evidence indicating that spontaneously generated analogies can play a significant role in expert problem solving. Focuses on an evaluation strategy known as bridging that has been observed in solutions to both science and mathematics problems. Contains 23 references. (DDR)

Reports on a study of the relationship between written content and its illustration. Also explores the problem of image comprehension. The study involved students (n=78) in a teacher training course. Concludes that very strong inducements to attract attention to illustration must be included in the text. (Contains 35 references.) (DDR)

Examines third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. Concludes that few students use a single model consistently. (Contains 27 references.) (DDR)
