We tested whether mental rotation training improved math performance in 6- to 8-year-olds. Children were pretested on a range of number and math skills. Then one group received a single session of mental rotation training using an object completion task that had previously improved spatial ability in children this age (Ehrlich, Levine, &…

Community colleges increase college access--extending postsecondary educational opportunities to students who otherwise may not have access, but they also exhibit low rates of program completion and transfer to four-year colleges. Sociological research on community colleges focuses on the tension between increasing educational opportunity and…

This study tested the acceptability and efficacy of an innovative intelligent tutoring system (ITS), "Adventures Aboard the S.S. GRIN," that translates the evidence-based in-person Social Skills Group Intervention (SSGRIN), into an interactive game-based social tutorial. This randomized controlled pilot trial tested the first half of the…

This study investigates variations in how users exert agency and control over their choice patterns within the game-based ITS, iSTART-2, and how these individual differences relate to performance. Seventy-six college students interacted freely with iSTART-2 for approximately 2 hours. The current work captures and classifies variations in students'…

Metacognitive awareness has been shown to be a critical skill for academic success. However, students often struggle to regulate this ability during learning tasks. The current study investigates how features designed to promote metacognitive awareness can be built into the game-based intelligent tutoring system (ITS) iSTART-2. College students…

Online professional development (OPD) for teachers is an increasingly popular and viable alternative to face-to-face professional development. While OPD can be effective, little is known about OPD's design and implementation features that maximize its impact. Using data from a large-scale OPD initiative, this correlational study (N = 1231)…

The purposes of this study were to investigate the effects of an intervention designed to improve at-risk 4th graders' understanding of fractions and to examine the processes by which effects occurred. The intervention focused more on the measurement interpretation of fractions; the control condition focused more on the part-whole interpretation…

If the true efficacy of preservice programs in the overall development of science teachers is to be accurately assessed, researchers and practitioners must work toward establishing a solid research base that critically examines the linkages between teacher preparation, classroom instruction, and pupil learning, to act as a lens to guide practice…

This large-scale effectiveness trial found a significant positive effect for high schools using Cognitive Tutor Algebra I (CTAI) in their second year of implementation, relative to similar schools that continued to use existing textbook-based algebra curricula. This positive result is important for educators and policymakers seeking ways to…

The Project on Incentives in Teaching (POINT) was a three-year study conducted in the Metropolitan Nashville School System from 2006-07 through 2008-09, in which middle school mathematics teachers voluntarily participated in a controlled experiment to assess the effect of financial rewards for teachers whose students showed unusually large gains…

Alum Rock Elementary Union School District had an interest in a middle school program being introduced by Teachers' Curriculum Institute (TCI) called "History Alive!" Supplementary materials from TCI were already in use in many of the classrooms and several of the district administrators were interested in whether the full middle school…
