Three-dimensional haptic matrices were pilot-tested as a nonvisual measure of cognitive ability. The results indicated that they correlated with convergent measures, with emphasis on spatial processing and that the participants who described items "visually" completed them more quickly and accurately and tended to have become visually…

Several visuo-motor tasks can be used to demonstrate biases towards left hemispace in schizophrenic patients, suggesting a minor right hemineglect. Recent studies in neglect patients used a new number bisection task to highlight a lateralized defect in their visuo-spatial representation of numbers. To test a possible lateralized representational…

Developing a software environment to enhance 3D geometric proficiency demands the consideration of theoretical views of the learning process. Simultaneously, this effort requires taking into account the range of tools that technology offers, as well as their limitations. In this paper, we report on the design of Virtual Spaces 1.0 software, a…

In the summer of 2009, a professional development partnership was established between the Peoria Public School District (PPSD), a local education agency (LEA), and Illinois State University (ISU) to improve geometric and trigonometric knowledge and skill for high school mathematics teachers as part of the Illinois Mathematics and Science…

This study presents the results of a multi-year mixed-methods study of students' performance (n = 94) and experiences (n = 28) with electromagnetics in an elective Electrical and Computer Engineering Technology RF communications course. Data sources used in this study include academic transcripts, course exams, interviews, a learning styles…

This study examined progress after 1 year of treatment for children with autism who received a mean of 36 hours per week one-to-one University of California at Los Angeles Applied Behavior Analysis (UCLA ABA) treatment. Two types of service provision were compared: an intensive clinic based treatment model with all treatment personnel (N = 23),…

The purpose of this study is to determine if the Sharpening Math Skills Lab technology-mediated mathematics instructional practices for math-delayed middle school students have positive effects on their mathematics achievement and spatial visualization ability and to gauge student engagement in learning, implementation of the principles of…

This article describes how spatial instruction with preservice teachers can be implemented in a middle-grades mathematics methods class. A "Reflect and Discuss" section is included for professional development study. (Contains 4 figures.)

As well as being important for school mathematics, spatial thinking is a big component of advanced mathematical studies too. As Jones (2001:55) points out, "Much of the thinking that is required in higher mathematics is spatial in nature. Einstein's comments on thinking in images are well known. Numerous mathematicians report using spatial…

The present study is designed to cross-validate the findings of an earlier component analysis of orthographic-projection, spatial-ability items. The earlier research identified four design components that contribute to the difficulty of orthographic-projection items. The research found that increasing Rasch item difficulties on component…

A spatial view of technology involves the relationships in space between technologies, placing significance on the actual dispersion of technology and relations of dependence and support between any particular technology and various social, chemical and biological dimensions. This paper seeks to elaborate a view of technology that is primarily…

Junior high school aged academically precocious youths participated in two experiments. In Experiment 1, Ss were required to closely process a spatially organized map or a list map prior to hearing a related prose passage. In Experiment 2, a spatially organized map was presented either before or after Ss listened to prose passages. Results…

The quality of representations of nine spatial arrays varying in transparency and occlusion was observed in order to test the generalization that younger children are concerned about the ambiguity of their representations and to observe the influence of a change in the medium used to create the representations. Children 5, 7, and 9 years old…

The study was designed to evaluate a hypothesis derived from recent trends in cognitive theory. The hypothesis concerned whether spatial environment information stored in memory is primarily analog or propositional. A related question concerned whether differences between analog and propositional processes underlie individual differences in the…

The hypotheses that deaf students would be more field dependent than hearing students and that their competence in communication skills would be related to field dependence were supported for a group of 77 male and 67 female deaf students at the National Technical Institute for the Deaf. Stepwise multiple regression analyses of the data showed…
