The influence of prior knowledge and cognitive development on the effectiveness of iconic representations in science visualizations was examined. Middle and high school students (N = 186) were given narrated visualizations of two chemistry topics: Kinetic Molecular Theory (Day 1) and Ideal Gas Laws (Day 2).

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…

Described is an investigation that determined whether young children have schemas for environmental information. The results are discussed with reference to the importance of memory schemas for learning about the environment. (KR)

Investigated was the relationship between spatial visualization and cognitive development in a sample of 88 Australian freshman teacher education students. Results support the hypothesis that enhanced capacity to visualize is an outcome of overall cognitive development. (HM)

Proposed is a hierarchy of visual learning giving three primary stages of visual learning as well as seven hierarchical stages. A clarification of terms associated with visual learning is presented. (KR)
