Teacher-child interaction quality was measured using the "Classroom Assessment Scoring System" (CLASS) on five observational cycles within a school day. Several different metrics of stability…

Research Findings: Given the variable nature of early childhood settings, practitioners and researchers need better guidance on what conditions influence observations conducted within early childhood settings (National Research Council, 2008). Using 230 observations from 23 three- and four-year-old children, we conducted a Generalizability study…

This research investigated how freshman students' epistemological beliefs in physics are impacted by gender and academic performance in a general physics course.

In response to growing interest in mindfulness as a support for educators, the current study sought to create and test a new multidimensional and multi-informant measure of teacher mindfulness in the classroom. To counter some of the limitations of context-general self-reports, we designed two theoretically based classroom-specific measures that…

Leaders, policymakers, and systems developers seek to improve early childhood programs through data driven decision-making. Data can be useful for informing continuous quality improvement efforts at the classroom and program level and for creating support for workforce development at the system level. Early childhood program leaders use…
