An Investigation Of The Usefulness And Predictive Ability Of The College Student Inventory At A Small, Private, Technological Institution In The Southeast, Jessica Paula Ha

Theses and Dissertations

Over the past several decades, retention research has focused on influential factors related to student persistence, specifically first-year persistence. Past research has identified the importance of prior academic achievement and demographic factors and, more recently, non-cognitive, psychosocial factors. In practice, first-year programs and the use of early intervention tools such as the College Student Inventory (CSI) have increased. However, practices still seem to lag behind theory and research, as first-year retention and six-year graduation rates remain stable at 74% and 59%, respectively (Kena et al., 2015; NCHEMS, 2016). We also know that the causes and characteristics of retention tend to …

The Look Of Pedagogical Content Knowledge In Middle School Statistics, Dhimitraq Duni

Theses and Dissertations

In this study, I attempt to examine the nature of pedagogical content knowledge (Shulman, 1986) that teachers exhibit while observing computer-animated animations that bring up pedagogical issues in the classroom. In-service teachers were asked to view different animations and react to different prompts about the animations. Later, teachers were interviewed to prompt more discussion of pedagogical issues with the intention of clarifying their stance and their knowledge of pedagogy. The computer animations were utilized as a surrogate for classroom teaching, highlighting issues that could be otherwise overlooked during live teaching observation.

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 …
