Spatial reasoning is a valuable cognitive tool which enables navigation of the body in relation to other objects in space, permits deconstruction of dimensional forms, allows reconstruction of two-dimensional representations into three-dimensional objects, and facilitates diagramming of processes or concepts. A considerable body of work has…

This study explored the interest, outcome expectations, choice goals and choice actions in engineering and technology, collaboration value, problem solving attitudes, and spatial reasoning and orientation skills of 63 middle school females in grades six, seven, and eight. The participants were involved in a five full-day coding robotics summer…

This study determined the test-retest reliability of 10 sensorimotor skills assessed by the Senaptec Sensory Station in a population of 100 (80 female, age = 21.6 ± 2.8 years) college-aged individuals (18-30 years). Separate intraclass correlation coefficients (ICCs) with a two-way mixed-effects model, absolute agreement, and 95% confidence…

At the highest level, this dissertation is a case study on how bias can become encoded into the tools used to measure a construct and into the very definition of the construct itself. In this case, the construct is spatial ability. This dissertation focuses on the validity and accuracy of spatial tests and illuminates gender bias that is…

Drawing on a social identity framework of mathematical development, the authors present a model, Improving Girls' Math Identity (IGMI), designed to address two key "leaks" in the female STEM pipeline: undergraduate and middle school. IGMI involves a supportive professional development network for undergraduate women preparing to…

The purpose of this study was to determine the effect of landmarks on learning basketball lay-up in beginners. Twenty-seven females (age = 20.30 ± 0.24 years, height = 164.37 ± 0.53 cm) participated in this study. They were assigned to three groups: no landmark group, colored landmark group, and black and white landmark group. All participants…

This article presents the research findings of a multidisciplinary team's collective research effort at one university over a five-year period as funded by the National Science Foundation's "Improving Undergraduate STEM Education" (IUSE) program. A collaborative learning and retention action research effort at a large Hispanic Serving…

Infants' motor skill development triggers changes in parent-infant interactions, exploration, and play behaviors, particularly during periods of locomotor transitions. We investigated how these transitions reorganized infants' and mothers' explorations of spatial layouts. Thirteen infants and their mothers were followed biweekly from the age of 6…

Histone acetylation is essential for hippocampal memory formation in young adult rodents. Although dysfunctional histone acetylation has been associated with age-related memory decline in male rodents, little is known about whether histone acetylation is altered by aging in female rodents. In young female mice, the ability of 17ß-estradiol…

Studies showed that two-dimensional (2D) and three-dimensional (3D) educational content contributes to learning. Although there were many studies with 3D stereoscopic learning environments, only a few studies reported on the differences between real, 2D, and 3D scenes, as far as cognitive load and attentional demands were concerned. We used…

Although women are underrepresented in the most mathematically intensive fields, the gender gap in these fields has narrowed over the past 2 decades. In my E. L. Thorndike address I summarized the temporal trends in sex differences for 8 fields and considered factors that drive both the underrepresentation of women and its recent narrowing. I…

Background: Developing sufficient mathematical skills is a prerequisite to function adequately in society today. Given this, an important task is to increase our understanding regarding the cognitive mechanisms underlying young people's acquisition of early number skills and formal mathematical knowledge. Aims: The purpose was to examine whether…

Here we apply a method for automated segmentation of the hippocampus in 3D high-resolution structural brain MRI scans. One hundred and four healthy young adults completed twenty one tasks measuring abstract, verbal, and spatial intelligence, along with working memory, executive control, attention, and processing speed. After permutation tests…

In two experiments the neuronal mechanisms of sex differences in mental rotation were investigated. In Experiment 1 cortical activation was studied in women and men with similar levels of mental rotation ability (high, and average to low), who were equalized with respect to general intelligence. Sex difference in neuroelectric patterns of brain…

While current educational standards serve to ensure all students have access to quality education that engages them in learning the skills that STEM teaches, there continues to be a gap in female students taking STEM-related classes in high school and subsequently entering STEM related careers. Gaining female learners' interest in STEM during…
