We used a cluster-randomized controlled trial to examine the impacts of a technology- and game-based social-emotional program, the "Adventures Aboard the S.S. GRIN" ("Adventures"), on students' social skills development. Eighty-eight third-grade classrooms (N = 1645 third-grade students) across four California public school…

School closures because of natural phenomena, such as COVID-19, underscore long-standing gaps in access to science education in the United States of America, particularly for young students. When educators have to pivot to deliver virtual instruction, it is important to identify feasible remote learning strategies for science content across formal…

An extensive body of empirical evidence shows that math skills at school entry are the strongest predictor of later academic success and educational attainment, but many children lack the opportunity to build the math skills needed for future success. Children who begin school with relatively low levels of math knowledge are at risk of falling…

Background/Context: Poor social emotional learning (SEL) development places students at heightened risk for bullying, teasing, and social isolation (Asher, et al., 1996; Solberg, et al., 2007). As students experience social failure, school becomes an aversive place which they may actively try to avoid (Gazelle & Druhen, 2009; Ladd, 2006).…

With only 40% of students proficient in math by 4th grade, the U.S. faces an acute need to scale innovative approaches to help close the math achievement gap. Closing this gap is particularly critical in order to support effective Science, Technology, Engineering, and Mathematics (STEM) learning and prepare the future workforce for…

Background/Context: Mathematics education, especially at early grade levels, continues to be an important focus for national education improvement efforts, and more districts are introducing technology as part of their solution. Along with increasing consistent delivery of personalized and individualized learning to students, technology- and…
