Describes how to use homemade tiles, sketches, and the box method to reach a broader group of students for successful algebra learning. Provides a list of concepts appropriate for such an approach. (KHR)

Summarizes findings from research related to spatial abilities. Provided are suggestions for developing spatial abilities. Lists nine references. (YP)

Two authors introduce the topic of visualization in mathematics education. Fourteen articles are briefly described. (YP)

Examines the relationship between visualization and the middle school mathematics curriculum. Gives an overview of where and how visualization interacts with the curriculum. Investigates the role of visualization in developing inductive/deductive and proportional reasoning. (YP)

Describes an activity in which students write guided-imagery scripts that are related to works of literature. (MM)

Protocols of people attempting to solve syllogistic problems and explaining how they reached their conclusions were examined. Two main groups of subjects were identified. One group represented the relationship between classes in a spatial manner supplemented by verbal representation. The other group used a primarily verbal representation. A…

Four groups of 12 young adult deaf subjects evaluated 2 aspects of lipreading training: source of video feedback (self or trainer) and timing of feedback (during or after speech production). Results substantiate the beneficial effects of multisensory feedback by practicing lipreading of one's own speech production. (Author/JDD)

Describes two thought experiments, involving visualizing the behavior of functions, that can be turned into computer experiments. (MKR)

New developments for solving the validation problem are applied to measuring and validating spatial modifiability. Results from 582 Air Force recruits support construct and criterion-related validities for the cognitive modifiability of spatial visualization items. Results also support modifiability as a direct measurement of learning ability.…

Comparison of the mental rotation skill of mathematically talented male (n=152) and female (n=143) high school juniors under both timed and extended time conditions showed higher performance by males under both conditions, but the male advantage decreased substantially when the effect of time was minimized. (Author/DB)

Presents concepts from von Wodtke's book, "Mind over Media," to suggest ways to teach thinking skills important for the electronic information age. Topics covered include how to use media interactively, navigating information environments, developing cognitive maps of media space, visualization, creative thinking, and collaboration. (KRN)

Examined the use of the TREC Information Retrieval Test Collection for evaluating visual information retrieval interfaces (VIRI). Found that TREC data sets were suitable as development tools for VIRIs and traditional information retrieval systems and that the computational cost of organizing data into useful visual fields were high and related to…

Presents interesting activities to develop mental imagery and the ability to transform these images. Concludes that using images facilitates mathematical thought in numerical and geometric settings. (ASK)

Describes visualization methods used to design projects intended to improve the quality of life in developing countries, but which are also applicable to group problem-solving situations. Details main stages of a case study. Demonstrates that the techniques improve the efficiency and effectiveness of the problem-solving process and the quality of…

Three teaching strategies for problem solving proved to be successful with undergraduates with deafness enrolled in mathematics courses. Strategies included giving an explanation to a peer observer in sign language, visualizing the problem-solving process prior to starting to solve a problem, and observing the teacher modeling the analytical…
