The current study investigated the effectiveness of three distinct educational technologies--two game-based applications (From Here to There and DragonBox 12+) and two modes of online problem sets in ASSISTments (an Immediate Feedback condition and an Active Control condition with no immediate feedback) on Grade 7 students' algebraic knowledge.…

Mission HydroSci (MHS) is a 3D game-based learning environment and curriculum that supports middle school student learning of water systems science and scientific argumentation. MHS is a rigorous, coherent and engaging 6 to 8-day curriculum with all learning activities and social interactions taking place in the virtual world and with teachers…

When people make judgments of learning (JOLs) after studying paired associates, the process they engage in to monitor their learning can directly enhance learning for some types of material (Soderstrom et al. 2015). The current experiments investigated whether JOLs directly enhance learning educationally relevant texts. Across 5 experiments (N =…

Scholars and practitioners have called for personalized and widely accessible professional development (PD) for teachers. Yet, a long-standing tension between customizing support and increasing access to such support has hindered the scale-up of high-quality PD for individual teachers. This study addresses this challenge by developing a…

The effectiveness of an experimental middle school fraction intervention was evaluated. The intervention was centered on the number line and incorporated key principles from the science of learning. Sixth graders (N = 51) who struggled with fraction concepts were randomly assigned at the student level to the experimental intervention (n = 28) or…

Although basing instruction on learning trajectories (LTs) is often recommended, there is little direct evidence regarding the premise of a LT approach--that instruction should be presented (only) one LT level beyond a child's present level. We evaluated this hypothesis in the domain of early shape composition. One group of preschoolers, who were…

Schools in the Internationals Network for Public Schools (Internationals) are public middle schools, high schools, and academies (i.e., schools within schools) that serve secondary English language learners (ELLs)--in particular, ELLs who have been enrolled in U.S. schools for fewer than 4 years and who are at the lowest levels of English…

The Science Notebook in a Universal Design for Learning Environment (SNUDLE) is a digital notebook that uses the Universal Design for Learning framework to support active science learning among elementary school students, particularly those who struggle with reading and writing or are unmotivated to learn science. Preliminary findings from the…

The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded prealgebraic reasoning instruction, improved word-problem performance. Students with mathematics difficulty (MD; n = 304) were randomly assigned to a business-as-usual condition or 1 of 2 variants of word-problem intervention. The…

This study investigated: 1) the influence of alphabet instructional content (letter names, letter sounds, or both) on alphabet learning and engagement of English only and dual language learner (DLL) children, and 2) the relation between children's initial status and growth in three underlying cognitive learning processes (paired-associate,…

The aim of this study was to explore how the Coding as Another Language (CAL) curriculum, developed by Boston College's DevTech Research Group and utilizing the ScratchJr app, impacted students' computational thinking, coding skills, and reading comprehension. To accomplish this, the research team randomly assigned thirteen schools in a…

This study examined the initial efficacy of World Generation (WorldGen), a Tier I social studies instructional approach for emergent bilingual (EB) students and their native English-speaking (non-EB) peers in Grades 6 and 7. WorldGen builds on prior research on instructional practices that have been associated with improved content knowledge and…

Preschool teachers from a high-poverty, urban school district were trained to implement Story Talk, a book reading intervention designed to increase children's vocabulary and language development using supportive materials and strategic individualized coaching. Thirty-five teachers were randomly assigned by site to the intervention (20) or the…

An ever-growing call for the use of evidence-based practice has come up against the logistical hurdles of a lack of resources and expertise, particularly in rural schools that work with historically underserved students. Although integrated learning systems (ILSs)--stable and likely requiring fewer resources than personnel--do not offer a complete…

The purpose of this research study was to evaluate iPersonalize, a gamified instructional approach developed by Fullerton School District (FSD) in California to encourage student engagement and promote achievement. An instructional approach is considered gamified when it incorporates computer game elements to augment existing classroom,…
