Differences In Spatial Visualization Ability And Vividness Of Spatial Imagery Between People With And Without Aphantasia, Anita Crowder

Theses and Dissertations

Mathematics education researchers have examined the relationship between visualization and mathematics for decades (e.g., Arcavi, 2003; Bishop, 1991; Duval, 1999; Fennema & Tartre, 1985; Presmeg, 1986). Studies have linked spatial visualization ability, such as measured in mental rotation tasks, directly to mathematics self-efficacy (Pajares & Kranzler, 1995; Weckbacher & Okamoto, 2014), which in turn influences mathematics achievement (Casey, Nuttall, & Pezaris, 1997). With the important role that spatial visualization plays in learning mathematics, the recent identification of congenital aphantasia (Zeman, Dewar, & Della Sala, 2015), which is the lack of mental imagery ability, has raised new questions for mathematics education …

Virginia Commonwealth University, 2018

Director: Charol Shakeshaft, Ph.D., Professor, Department of Educational Leadership

Policy goals may be impossible to achieve at the classroom level (Ravitch, 2014), as policy depends on those who implement it (Lipsky, 1980). The purpose of this research was to investigate how the voluntary environmental educational executive order, EO42, was implemented and executed in a Central Virginia …
