Certain misunderstandings in science, mathematics, and computer programing reflect analogous underlying difficulties. These misunderstandings are examined through four knowledge levels: (1) content; (2) problem-solving; (3) epistemic; and (4) inquiry. Analysis of several examples shows that misunderstandings have causes at multiple levels, and…

Related the four scales of the Myers-Briggs Type Indicator, a measure of personality, to learning preferences. The personality types of 491 first- and second-year language students were compared with a sample of 18,592 general college students. Statistically, more thinking and intuitive types were found in the language students. (Author/LMO)

Presents a covariation approach to learning exponential and logarithmic functions based on a primitive multiplicative operation labeled splitting that is not repeated addition. Suggests that students need the opportunity to build a number system from splitting structures and their geometric forms. (30 references) (MKR)

Conceptions of (n=13) grade-11 chemistry students via interviews were grouped into 6 categories related to students' preferred explanations for solubility phenomena. Argues that an understanding of the typical conceptions used by students should form an integral component of chemistry teaching, both as points of origin for lesson planning and for…

Involves secondary students in a study designed to allow investigation into how different levels of information presented by various technologies (chemical indicators, pH meters, and microcomputer-based laboratories-MBLs) affected students' understanding of acid, base, and pH concepts. Results showed that students using MBLs exhibited a greater…

Describes a model-centered, computer-supported semester-long science curriculum (Model-based Analysis and Reasoning in Science) for middle school students designed to encourage conceptual understanding and to foster the development of model-based reasoning skills. (ZWH)

Examined how task design influences the effectiveness of peer collaboration in facilitating students' conceptual change in physics. Subjects were 8- to 12-year olds studying heating and cooling. Results showed the general superiority of collaborative tasks that both facilitate critical testing and require rules; task designs deploying one feature…

Discusses how postmodern theories might contribute to the development of Asian American Studies as an intellectual field of inquiry and a vehicle for political and social change. The author explains how the postmodern direction toward inclusion, multiplicity, and heterogeneity is particularly well suited to an analysis of the contemporary Asian…

Describes the use of a graphic organizer--webs--to help students learn to connect concepts in mathematics. (MKR)

Three experiments used an object-examining task to explore infants' attention to function and form-function correlations. The results suggested a developmental progression from attending only to the form of objects, to attending to form and function as separate properties, and finally to attending to the relationship between form and function.…

Spatial cognition entails the ability to mentally represent spatial relations and to anticipate the course and outcome of transformations applied to those relations. The developmental histories of four tasks used to assess the maturity of spatial cognition in children are described. Significant effects were found for age, gender, task, and for…

Many students can calculate the arithmetic mean but do not understand the concept. The article presents four activities designed to help elementary and middle school students develop this concept. The activities presented assume previous exposure to the computational algorithm for the arithmetic mean. (Author/EK)

Presents correct solutions to an osmosis problem of two high school science students who relied on inaccurate and inappropriate conceptual knowledge. Identifies characteristics of the problem solvers, salient properties of the problem that could contribute to the problem misrepresentation, and spurious correct answers. (27 references) (Author/MKR)

Investigated the acquisition and maturation of the infinity concept in mathematics of students ages 13-15. Found the infinity concept is learned by students only when provided with appropriate guidance. (Author/MKR)

Examined the impact of information activation on individuals in different mood states. Results of two experiments suggest that happy mood supports judgmental inferences based on general knowledge structures, whereas sad mood facilitates the conservation of information. Findings support assertions that affective states influence the style of…
