In laboratory study environments, dialogue-videos, or videos of a tutor and a tutee solving problems together, have been shown to more effectively improve student learning than monologue-videos, or videos of tutors solving problems alone. Yet, few studies have replicated these findings in the context of authentic university classrooms. Here, we…

We present an inquiry-based, aquatic science professional development (PD) for upper-elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers' characteristics and the grade band of the students. Our study lends support to the assertion that inquiry- and content-focused PD, paired with…

At a research University near the east coast, researchers restructured a College Algebra course by formatting the course into two large lectures a week, an active recitation size laboratory class once a week, and an extra day devoted to active group work called Supplemental Practice (SP). SP was added as an extra day of class where the SP leader…

The purpose of this study was to identify significant differences in academic achievement among virtual students of various backgrounds, demographics, and virtual learning environments. The study also sought to identify factors that may predict the academic achievement, as defined by final course grade, of virtual students. This study examined…
