Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

The 3D cube figures used by Shepard and Metzler [Shepard, R. N., & Metzler, J. (1971). "Mental rotation of three-dimensional objects." "Science," 171, 701-703] have been applied in a broad range of studies on mental rotation. This note provides a brief background on these figures, their general use in cognitive psychology and their role in…

In this case study, we are able to take a close look at a situation not often encountered in the literature on ICTs in emerging economies: a private company from an emerging economy provided much-needed funding for a US NASA higher learning consortium through a contract for training and research and development in 3D visualization. This study…

Investigates the role active, self-produced movement might play in the type of rotation task typically used to assess spatial orientation in children 12 months to 18 months of age. Results indicated that, at least at 12 months, spatial orientation was indeed facilitated by allowing the infants (n = 13) to move through space on their own. (RH)

This study with 16 adolescents with mental retardation compared free-recall rates under two encoding conditions: (1) fade-in, initially presenting pictures out of focus then slowly fading them into focus; and (2) fade-out, slowly blurring originally clear pictures. Results indicated that free-recall rates were greater for the fade-in items for…

Investigated visuo-spatial ability of a control group and an experimental group (receiving 30 minutes of interaction each week) in undergraduate college biology. Results for the subjects (N=84) indicate that visuo-spatial aptitude can be enhanced through teaching. (Descriptions of interaction sessions and explanations of tasks are included.) (DH)

Investigated differences in performance between sexes on a spatial visualization task constructing pentaminos and whether supplying clues to the learner to guide would be a factor in performance. Concluded that males were more adept at identifying the shapes than females. (YP)

The study, with 15 language-learning-disabled and 15 normally achieving children (ages 6-8), found a significant positive correlation between the severity of the language disability and accuracy on 2 of 3 imagery tasks. Performance on one imagery task was significantly related to reading achievement, and imagery ability was related more strongly…

The study with 34 gifted fifth-grade students found that a concrete sequential approach to developing visual literacy was more effective than an abstract visualization approach. Subjects either received guided visualization or direct instruction on such art concepts as shape, form, line, color, perspective, variety, and unity. (DB)

Explores the role of spatial orientation skill in the solution of mathematics problems. Reports the role of estimating the approximate magnitude of a figure; demonstrating the flexibility to change; adding marks to show relationships; moving or assessing the size and shape of figure; and getting the correct answer. (YP)

Six types of remedial projection slide programs were tested on male students (n=120) who showed difficulty in visualizing rotation from molecular diagrams. There were no significant differences in improvement of understanding which were dependent on the number of remedial diagrams. However, when slides contained multicolored diagrams, which 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.…

Focuses on use of computer-drawn faces to explore visualization in learning and for presenting multivariate data. Prior and new research are reviewed and future applications are discussed. "Autocorrelation-face," a graphics representation created from mathematical analysis of voice input, and its potential as a learning aid for the deaf are…

Examined the stability of two aspects of infant visual attention derived from the paired-comparison procedure in infants tested at 6, 7, and 8 months of age. The two aspects were novelty preference and exposure time. Suggests that both novelty and exposure-time scores reflect moderately stable but independent characteristics of infant behavior.…

Examines the effect of verbalization on the formation and retention of mental images in children in kindergarten, first, and fifth grades. Reports no self-generated verbalization effect with gender or ability level and no retention effect. (Author)
