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.…

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…

Prior research has shown that game-based learning tools, such as DragonBox 12+, support algebraic understanding and that students' in-game progress positively predicts their later performance. Using data from 253 seventh-graders (12-13 years old) who played DragonBox as a part of technology intervention, we examined (a) the relations between…

School closures because of natural phenomena, such as COVID-19, have emphasized the importance of effective distance learning strategies when there are no in-person alternatives. Although infrequently mentioned in discussions of student performance, social-emotional skill building came to the forefront of conversations due to the isolation and…

COVID-19 contributed to the largest student performance decline in mathematics since 1990. The nation needs cost-effective mathematic interventions to address this drop and improve students' mathematics performance. This study presents a cost-effectiveness analysis (CEA) of three algebraic technological applications, across four conditions:…
