Aim/Purpose: Although many computer science measures have been proposed, visualizing individual students' capabilities is difficult, as those measures often rely on specific tools and methods or are not graded. To solve these problems, we propose a rubric for measuring and visualizing the effects of learning computer programming for elementary…

There is an emerging consensus that spatial thinking is fundamental to later success in math and science. The goals of this study were to design and evaluate a novel test of three-dimensional (3D) mental rotation for 4- to 8-year-old children (N?=?165) that uses tangible 3D objects. Results revealed that the measure was both valid and reliable and…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

Across many academic disciplines visualisation and notation systems are used for modelling data and developing theory, but in child development visual models are not widely used; yet researchers and students of developmental difficulties may benefit from a visualisation and notation system which can clearly map developmental outcomes and…

The development of mental imagery in relation to the comprehension of concrete proverbs (e.g., "one rotten apple spoils the barrel") was examined in children, adolescents, and adults who were ages 11 to 29 years old (n = 210). The findings indicated that age-related changes occurred in mental imagery and in proverb comprehension during the years…

This study was undertaken to investigate (1) the findings of an exploratory study in which the Luquet-Piaget sequence of drawing was tentatively confirmed in children's drawings of a house with a tree behind it, (2) the relationship of house-tree task with selected Piagetian and two psychometric measures, and (3) synchronous development among…

Demonstrates that a representation of a figure through object reconstruction is prerequisite to recognizing the object figure from a collection of figures, which in turn is prerequisite to representing the object figure using a pencil-and-paper reproduction. (RL)

Changes in manipulative play with objects were examined in a longitudinal sample of 10 boys and 9 girls tested at ages 9, 13, and 18 months. Stability of individual differences in play was also examined. Each child was observed individually for 7 minutes in a room in which a tea set was the only toy present. Seven types of play behavior were…

Second- and fourth-grade children viewed a cylindrical object in nine positions and identified the 90- , 180- , or 270-degree positions from a set of photographs. Perspectives in which the object differed from the child's view in both left-right and near-far dimensions were more difficult than perspectives that only transformed one dimension.…

Previous literature on children's visual pattern perception has suggested that preschool children may process hierarchical forms in a manner different from that of older children and adults. Data from some studies suggested that children are holistic processors of pattern information, while other studies characterized children as piecemeal…

The relation of visual process to Piaget's stages of cognitive development was examined. The study utilized four age groups to correspond roughly to acquisition and consolidation periods of concrete and formal operations: 6 years - acquisition of concrete operations; 9 years - consolidation of concrete operations; 11 years - acquisition of formal…

An overview that gives an introduction to the theories, terms, concepts, and prior research conducted on visualization is presented. This information is to be used as a basis for developing spatial research studies that lend support to the theory that the engineering and technical design graphics curriculum is important in the development of…

The way that children construct the representation they use to solve transitive inference problems was examined. Forty-eight children 4.5 to 5 years old and 48 children 6 to 7 years old were asked to learn either a three-item series or a four-item nonseries. They were asked to learn the relationships between different colors of faces that were all…

Writing is a highly complex process requiring skills that are not possessed by all students. In some cases, students may have been taught writing skills before they were developmentally ready for them, thus diminishing their future ability to learn those skills. Some students may have specific learning disabilities, sometimes affecting only the…

This second article in a series on children's artistic learning reviews the developmental process of symbolization and symbol representation by young children and analyzes the symbolism in works by three boys. Practical teaching considerations are discussed. For part one of this series, see the September, 1980 issue of this journal. (SJL)
