Many generalization studies in education are typically based on a sample of 30-70 schools while the inference population is at least twenty times larger. This small sample to population size ratio limits the precision of design-based estimators of the population average treatment effect. Prior work has shown the potential of small area estimation…

The recent turn toward core practices and practice-based teacher education has been accompanied by a growing literature on the definitions, pedagogies to teach, and assessments of core practices. Despite these developments, the field lacks core practices performance assessments designed to be used across course sections, courses, and subjects.…

Augmented reality continues to be lauded as a disruptive innovation in education. This research examines the perspectives of AR using educators who are Innovators and First Adopters in Roger's Diffusion of Innovation Scale. Attitudes towards AR were examined through a survey that included Likert-scale items and open-ended qualitative items.…

Positioned in the context of experiential learning, this paper reports findings of a virtual reality field trip (VRFT) in conjunction with an in-person field trip involving preservice teachers in an elementary science methods course to a local natural history museum. Findings included that virtual reality (VR) is best used after a field trip to…

Via a multi-domain, multi-response classroom observation instrument, we observed and analyzed treatment and control teachers' pedagogical differences when applying cooperative, collaborative, and peer-tutoring (CCP) strategies in Grade 1 bilingual classrooms with English learners (ELs). We found that with the support of ongoing, structured, and…

In this empirical study we examined the effect of a literacy-infused science intervention on fifth grade economically challenged students' science achievement in the curriculum-based and standardized assessments. A total of 27 treatment students and 20 comparison students from two intermediate schools in a rural district in South Texas in the…

The purpose of this study was to identify science teachers' perceptions concerning the use of technology in science laboratories and identify teachers' concerns and recommendations for improving students' learning. Survey methodology with electronic delivery was used to gather data from 164 science teachers representing Texas public schools. The…
