Graphical representations of geometrical objects from high school textbooks are categorized according to the implicit conventions underlying their display. The fact that specific illustrations can lead to students' misconceptions about geometric objects is analyzed in relationship to the principle of parallel projection with implications for the…

Describes a process approach to teaching and learning in preschool settings. The approach uses child-initiated play in a prepared environment, and encourages children's formation of symbolic mental representations through social interaction and mediation. Offers guidelines for the implementation of the process approach. (MM)

This article, the fourth in a series on work conducted at the Texas Center for Educational Technology and the University of Texas, discusses evaluative measures needed to assess the improvements that educational technology may have on students' problem solving, critical thinking, and content-level abilities. An annotated list of standardized tests…

Reports a study designed to identify 9 and 11 year olds' ways of drawing nets of solids and to provide opportunities for them to reflect on their models in whole class discussions. Results indicated that children's views of solids' nets progressed from more global and holistic to more quantitative and analytic. (MDH)

Reviews the history of the concept of function, looks at its relationship with other sciences, and discusses its use in the study of real world situations. Discusses the process of constructing mathematical models of function and emphasizes the importance of the roles of the numerical, graphical, and algebraic representational forms. (MDH)

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

Discusses the use of feedback from students and the analysis of students' error patterns to understand why students develop misconceptions in mathematics. Looks at learning vis-a-vis the abstract nature of mathematics and the students' cognitive development. (MDH)

To evaluate the part that nascent skeptical doubt plays in shaping adolescent social-cognitive development, 61 high school students clearly classified as in concrete or formal operational stages of cognitive development completed a measure of epistemic stances. A relationship was found between cognitive and epistemic development. (SLD)

Forty children were divided into four groups and administered the Tower of Hanoi puzzle using static and dynamic approaches. The benefits of age and ability were indicated by significant improvement from the general failure of the four- to five-year olds to the success of the majority of the high ability seven- to eight-year olds. (Author/JDD)

The degree to which reading ability and intelligence, as measured by the Raven Progressive Matrices Test, were related was studied for 486 students in grades 2 through 12 in a small town, rural school system. Results indicate the strong and consistent relationship between general intelligence and reading ability. (SLD)

Six case studies were conducted on the use of business games and simulations in higher education. Results showed that cognitive learning was greatly affected by particular approaches of students; competitiveness tends to have a negative effect on cognitive gains; and learning is enhanced by advance briefing and tutor involvement during the game.…

Recall of "to-be-remembered items" benefited from schematically related, superordinate, and slot filler cues, but not coordinate cues. The relative strength of different relationships does not appear to change with age. Findings are consistent with the view that lexical memory is schematically and taxonomically organized from early…

Interviews with 7- to 11-year-old Scottish and French children indicated that formal education provided the context for the development of children's beliefs about, and representations of, institutional authority. The emergence of these representations was influenced by the children's social class and culture. (BC)

Children between the ages of seven and nine years were given metalinguistic tasks and measures of field dependence-independence (FDI). Results showed a common basis for FDI and metalinguistic problems requiring high levels of control of linguistic processing but not for FDI and problems requiring high levels of analysis of linguistic knowledge.…

Using case study data, determines high school pupils' and university students' (n=162) ability to predict possible outcomes of interactions between ecological populations . Results indicate the majority of respondents could predict interactive outcomes within a simple food web but not when the interaction involved multiple routes. (five…
