Young children tend to judge improbable events to be impossible, yet there is variability across age and across individuals. Our study examined parent-child conversations about impossible and improbable events and links between parents' explanations about those events and children's possibility judgments in a reasoning task. Regression analyses…

As discipline-based astronomy education researchers become more interested in experimentally testing innovative teaching strategies to enhance learning in undergraduate introductory astronomy survey courses ("ASTRO 101"), scholars are placing increased attention toward better understanding factors impacting student gain scores on the…

Maternal immune activity has been linked to children with autism spectrum disorder (ASD). We examined maternal occupational exposure to asthma-causing agents during pregnancy in relation to ASD risk. Our sample included 463 ASD cases and 710 general population controls from the Study to Explore Early Development whose mothers reported at least one…

School principals' education and professional experience shape their approach to school leadership and how successful their students will be.

This dissertation explores aspects of…

This qualitative, phenomenological case study was designed to illuminate the perceptions and experiences of eight undocumented community college students navigating the California public higher education systems with the aim of identifying factors associated with college persistence. These factors fall into three categories: financial, academic,…

The link between emotion regulation and academic achievement is well documented. Less is known about specific emotion regulation strategies that promote learning. Six- to 13-year-olds ("N" = 126) viewed a sad film and were instructed to reappraise the importance, reappraise the outcome, or ruminate about the sad events; another group…

Field instruction is a critical piece of undergraduate geoscience majors' education, and fieldwork remains a major part of the work of professional geologists. Despite the central importance of field education, there exists relatively little educational research exploring how students learn to solve problems in geological fieldwork. This study…

Social psychologists have shown experimentally that implicit race bias can influence an individual's behavior. Implicit bias has been suggested to be more subtle and less subject to cognitive control than more explicit forms of racial prejudice. Little is known about how implicit bias is manifest in naturally occurring social interaction. This…
