This article examines kindergarten children's experience of the COVID-19 pandemic. It aims to understand the children's thoughts, emotions, and coping strategies regarding the presence of the COVID-19 virus in their daily lives, using the salutogenic approach to study their sense of coherence and promote relevant professional instruction.…

Growing from the commognitive framework, this study is concerned with objectification -- a special way of talking about mathematical objects, which is key to one's concept formation. The study explores how objectification can be manifested in the discourse on square roots that unfolds in writing. The data comes from a class in a foundation…

Functions are all around us, disguised as actions on concrete objects. Composition of functions, too, is all around us, because these actions can be performed in succession, the output of one serving as the input for the next. In terms of Gray and Tall's (2001) "embodied objects" or Lakoff and Nunez's (2000) "mathematical idea…

Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

Four- and five-year-old children were asked to compare the burning times of pairs of partially synchronous lights differing in intensity, bulb size, or both. (Author/MP)

This study examines the effectiveness exercises based on the cognitive conflict, existing within the child, between two representational systems related to temperature: the qualitative-verbal one and the quantitative-numerical one as these relate to the advancement of children's understanding of the concept of temperature.

Opens with the theoretical construct of figural concepts. Argues that geometrical figures are characterized by both conceptual and sensorial properties. Investigates the effects of interaction between conceptual and figural components. Contains 19 references. (DDR)

Reports on research designed to discover whether certain conceptual difficulties experienced by present day students in the realm of action at a distance are parallel to the experiences of scientists in previous generations. Contains 60 references. (DDR)

A total of 84 Israeli middle- and upper-middle-class nursery school, second and fifth grade children were subjects for a study investigating parallel shifts in dimensional salience and the dominance of these dimensions as organizing principles in memory. (MS)

Identifies the conceptions of energy of preservice high school biology teachers. Findings indicate that this group of preservice teachers holds alternate conceptual frameworks when describing physical situations. Contains 35 references. (DDR)

Analyzed the Weigl-Goldstein-Scheerer Color-Form Test using a sample of Danish children. Distinguished three dimensions: configuration of sorting, verbalization of the sorting principle, and the flexibility of switching sorting principle. The three dimensions proved themselves to constitute the a-priori-defined gradients. Results indicated a…

The consistency, if any, with which force concepts are used by individual students in different, but closely related, contexts was investigated. A total of 534 university and high school students were tested to elicit their beliefs about the forces acting on various objects. Students' beliefs about the forces acting on objects at rest and in…

Three experiments using university students explored what constitutes an event and what determines its boundaries. Results supported the hypothesis that sequences of stimuli repeating in different contexts are cut out to become cognitive entities ("things" with a beginning and an end) in their own right. Results suggest that the…

School students' conceptual frameworks in astronomy and students' levels of knowledge and conceptualization were examined for 130 students in grades 2 through 12. Knowledge and conceptualization increased with school age. A test administered to 892 students in 7 schools demonstrated that schools contributed little to education in astronomy. (SLD)

This document reports on a study of 48 kindergarten children in Israel regarding their concepts of "solid" and "liquid." Children were asked to classify a set of 30 materials into two groups (a group of 9 liquids and a group of 21 solids). About 65% could classify liquids correctly, 50% could classify rigid materials correctly,…
