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…

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…

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)

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.…

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…

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)

In this concluding article of a six-part series on children's art, the author reviews the stages of children's development in relationship to the use of three-dimensional materials and suggests teaching methods which will help children to develop artistically. (Editor/SJL)

Examines the development of young children's analysis of spatial patterns--specifically, hierarchical letter and geometric forms. Suggests that although children as young as four years of age demonstrated substantial analytic competence, their ability to integrate the parts of the spatial array to form a coherent whole was weaker and more easily…

This study of 78 prelingually deaf children (ages 6-13) who were educated orally found that children up to 9 years old seemed to process written words by means of visual codes. Older children tended to differentiate and preferred either a visual or speech-based strategy, with the latter associated with better reading performance. (Author/JDD)

Approximately 100 national spelling bee finalists and their parents were surveyed concerning their early literacy experiences and spelling practices. The fourth-eighth grade spellers showed an early interest in language activities; passed through developmental spelling stages earlier than average; and mastered words via visual memory strategies,…

Describes five skills underpinning the understanding of geometry for primary and lower secondary mathematics students. Skill categories identified include (1) visual; (2) verbal; (3) drawing; (4) logical; and (5) application. Gives examples of skills appropriate for Van Hiele levels 1-3. (MDH)
