There is an increasing number of datasets with many participants, variables, or both, in education and other fields that often deal with large, multilevel data structures. Once initial confirmatory hypotheses are exhausted, it can be difficult to determine how best to explore the dataset to discover hidden relationships that could help to inform…

Across the disciplines of economics, political science, public policy, and now, education, the randomized controlled trial (RCT) is the preferred methodology for establishing causal inference about program impacts. But randomized experiments are not always feasible because of ethical, political, and/or practical considerations, so non-experimental…

This paper describes findings from a blocked randomized design (BRD) field study conducted to examine the "Next Generation Preschool Math" (NGPM) program's implementation in preschool classrooms and promise in improving young children's mathematic learning. NGPM integrates traditional preschool activities with developmentally appropriate…

The current study involved the development, implementation, and evaluation of a universal school-based intervention designed to promote health and wellbeing among educators. This study aims to further investigate the efficacy of contemplative practices as a support for teacher wellbeing. The study contributes a new perspective to the current…

Decades of evidence demonstrates that high-quality, well-implemented early education can positively impact the learning trajectories of vulnerable, high-needs young children. Yet, the majority of publicly-funded programs nationwide struggle to implement to quality standards with fidelity and fail to significantly advance children's early…

Children enter kindergarten with variable levels of mathematics skill and knowledge gained from informal learning opportunities at home, preschool, and daycare. Many perform well once they receive formal mathematics instruction. However, if students do not develop an initial understanding of the most basic aspects of formal mathematics, they are…

Widespread concern has been expressed about the persistent low mathematics achievement of students in the US, particularly for students from low-income and minority backgrounds and students with disabilities. Instructional gaming technology, when designed and fictionalized well, has the potential to improve the motivation and mathematics…

In this paper, the authors describe a case of measuring implementation fidelity within an evaluation of Math Recovery (MR), a pullout tutoring program for low-achieving first-graders. They use this case to address two aspects of implementation fidelity studies: (1) their feasibility with respect to unscripted interventions, and (2) their…

An educational intervention's effectiveness is judged by whether it produces positive outcomes for students, with the randomized controlled trial (CRT) as a valuable tool for determining intervention effects. However, the intervention-as-implemented in an experiment frequently differs from the intervention-as-designed, making it unclear whether…

Given the vital importance of using a scientific approach for curriculum development, the authors employed a design experiment methodology (Brown, 1992; Shavelson et al., 2003) to develop and evaluate, FUSION, a first grade mathematics intervention intended for students with or at-risk for mathematics disabilities. FUSION, funded through IES…
