Develops and tests a function-based approach to algebra called the Visual Mathematics curriculum in grades 7-9. Presents a theoretical framework for a systemic investigation of the structures of algebra word problems and their relationship to function-based solutions. Suggests new insights into categorizing word problems. (Contains 19 references.)…

Explored the progress of 15 first-graders as they learned about baling hay via a mnemonic visualization process. Using an integrated picture and a meaningful organized explanation of the hay-baling process produced superior learning, compared with a control group's progress using conventional guided reading techniques. (MLH)

Explores the way children visualize three dimensional shapes. Uses nine assessment tasks involving three dimensional objects to evaluate children's abilities. Indicates that students' visualization ability can be determined and would be an important and essential element in any overall assessment of spatial development. (ASK)

Presents a proposed information environment (PROPIE) for enhanced interaction and value-adding of electronic documents that allows users multiple ways to query intuitively and navigate information in an electronic document. Highlights include user interface technologies; visualization and interactive techniques; query and browsing processes; and…

Describes the two-course engineering design graphics sequence on introductory design and graphics topics. The first course focuses on conceptual design and the development of visualization and sketching skills while the second one concentrates on detail design and parametric modeling. (Contains 28 references.) (Author/ASK)

LYDIAN is an environment to support the teaching and learning of distributed algorithms. It provides a collection of distributed algorithms as well as continuous animations. Users can combine algorithms and animations with arbitrary network structures defining the interconnection and behavior of the distributed algorithm. Further, it facilitates…

With both "Cabri" and "Autograph" now venturing into 3D, the dimension that previously was only demonstrated in the classroom with a lot of arm waving and crude wire cages can now be explored dynamically on screen. "Cabri 3D" concentrates on constructions, using the principles of Euclidian geometry, whereas "Autograph" creates objects using a…

Humans see whole objects from input fragmented in space and time, yet spatiotemporal object perception is poorly understood. The authors propose the theory of spatiotemporal relatability (STR), which describes the visual information and processes that allow visible fragments revealed at different times and places, due to motion and occlusion, to…

In these studies, a vegetable can containing fluid was swung as a pendulum by supporting its end-lips with a pair of knife edges. The motion was measured with a capacitive sensor and the logarithmic decrement in free decay was estimated from computer-collected records. Measurements performed with nine different homogeneous liquids, distributed…

In order to facilitate the selection/prioritization process and bridge the gap of design research to design conceptualization, students need to visualize the big picture that describes how the research categories such as "user," "marketing," "functional/mechanical research" are related. This is achieved through the use of a visual storyboard. The…

This study aims to investigate the effects of virtual reality (VR)-based learning environment on learners of different spatial visualization abilities. The findings of the aptitude-by-treatment interaction study have shown that learners benefit most from the Guided VR mode, irrespective of their spatial visualization abilities. This indicates that…

Memory for the position of a moving target is often displaced in the direction of anticipated motion, and this has been referred to as "representational momentum". Such displacement might aid spatial localization by bridging the gap between perception and action, and might reflect a second-order isomorphism between subjective consequences of…

The author recounts experiences introducing a first grade class to the concept of symmetry. The lesson includes activities for developing recognition of objects that have symmetry as well as visualization of both horizontal and vertical lines of symmetry.

This article uses the story of The Wonderful Wizard of Oz (L. F. Baum, 1900) as a metaphor for exploring career counseling issues related to self-deception, loss, and the search for the "all-knowing" expert. The dynamics of the story can be applied to both counseling practice and counselor training. Cross-cultural issues are also considered.

The theme of the 38th meeting of the International Group for the Psychology of Mathematics Education (PME 38) and the 36th meeting of the North American Chapter of the Psychology of Mathematics Education (PME-NA 36) was "Mathematics Education at the Edge." Academically, the theme provides opportunities to highlight and examine…
