In the context of the sociocultural approach, the authors studied the problem of the development of the students' conceptual mental structures in the process of geometry teaching. An educational activity for the development of a generalized ability to solve geometry construction problems in electronic educational environment served as a…

The present study examined the moderating effects of intellectual functioning and ASD symptom severity on the relation between age and adaptive functioning in 220 youth with autism spectrum disorder (ASD). Regression analysis indicated that intellectual functioning and ASD symptom severity moderated the relation between age and adaptive…

One of the overarching goals of education is the development of intellectual abilities (IA). Yet, there are not enough tools to identify pedagogies that maximize students' IA. In this research, we consider the way teachers' reinforcing of versatility of opinions (pluralism) vs. teachers encouraging community views (communalism) has on developing…

This article reports on our work of developing a learning progression focusing on K-12 students' performances of using energy concept in their accounts of carbon-transforming processes in socio-ecological systems. Carbon-transforming processes--the ecological carbon cycle and the combustion of biomass and fossil fuels--provide all of the energy…

Ability and non-ability traits were examined as predictors of learning, operationalized as the development of knowledge structure accuracy, and exam performance in a semester-long course. As predicted by investment theories of intellectual development, both cognitive ability and non-ability traits were important determinants of learning and exam…

Describes the initial validation of a new instrument and comprehensive rating manual designed to enhance the accuracy of measurement of the Perry scheme. (Author)

Compared standardized versus semi-structured approach to measuring intellectual development to identify accurate methods to assess gender differences and similarities. Intellectual development was measured for 101 college freshmen using the Measure of Epistemological Reflection and a semi-structured interview. Results provide strong evidence that…

The relationship between higher order reasoning and sex bias was investigated among children 7, 9 and 11 years old. Children read arguments enhancing their own or other gender, then rated argument intelligence, judged other children based on observations, and justified their arguments. Findings showed that own-gender reasoning biases declined with…

Outlines a model of mathematical understanding as a whole, dynamic, nonlinear, recursive growing process, entailing "folding back" for the reconstruction of inner level knowing. Presents examples from seventh graders' work. Discusses teacher awareness of student level of understanding, and implications for development of mathematics…

Examined children's ability to settle causal relations and their capacity to make conclusions based on certain experiences and representations. Found that preschool children have a solid explanatory basis for their everyday life, within which facts are not generally accepted but are interpreted through a certain "logic," and the motives…

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

Reconstructs the process through which a student becomes familiar with new subject matters and unfamiliar rhetorical and linguistic conventions. Describes one writer's attempt to achieve "specialized disciplinary literacy." Suggests the writer must be able to integrate his/her knowledge of appropriate discourse conventions with a…

Examines whether participation in physical experiments together with social interaction with adults and school-mates favor the development of causal knowledge and the understanding of a complex physical subject. Concludes that the treatments can lead students to give up pre-causal explanations and to resort to physical ones. (Author/YP)

Many current studies have discovered that students tend to use either an Aristotelian or the Medieval impetus model rather than the Newtonian view in order to explain their experience. This preconceived knowledge may be important for students in learning mechanics. The purpose of this study was to identify and confirm the existence of a…

A study of the intellectual talents involved in learning a foreign language compared the composite predicted score of high school students on the Pimsleur Language Aptitude Battery with selected factor scores on the Structure of Intellect-Learning Abilities Test to determine whether any of the factors correlate highly with foreign language…
