Miller, Trey; Daugherty, Lindsay; Martorell, Paco; Gerber, Russell – Journal of Research on Educational Effectiveness, 2022
This is the first study to provide experimental evidence of the impact of corequisite remediation for students underprepared in reading and writing. We examine the short-term impacts of three different approaches to corequisite remediation that were implemented at five large urban community colleges in Texas, and we explore whether corequisites…

Chan, Wendy – Journal of Research on Educational Effectiveness, 2022
Over the past decade, statisticians have developed methods to improve generalizations from nonrandom samples using propensity score methods. While these methods contribute to generalization research, their effectiveness is limited by small sample sizes. Small area estimation is a class of model-based methods that address the imprecision due to…

Shand, Robert; Bowden, A. Brooks – Journal of Research on Educational Effectiveness, 2022
The economic evaluation of educational policies and programs employing the ingredients method for cost, cost-effectiveness, or benefit-cost analysis is no exception to the critique that economic models require an untenable number of assumptions. Educational economists must make assumptions due to two sources of uncertainty: model uncertainty, as…

Bulus, Metin – Journal of Research on Educational Effectiveness, 2022
Although Cattaneo et al. (2019) provided a data-driven framework for power computations for Regression Discontinuity Designs in line with rdrobust Stata and R commands, which allows higher-order functional forms for the score variable when using the non-parametric local polynomial estimation, analogous advancements in their parametric estimation…

Powell, Sarah R.; Berry, Katherine A.; Fall, Anna-Maria; Roberts, Greg; Barnes, Marcia A.; Fuchs, Lynn S.; Martinez-Lincoln, Amanda; Forsyth, Suzanne R.; Vinsonhaler, Rebecca K.; Benz, Sarah A.; Zaparolli, Brenda L.; Lin, Xin – Journal of Research on Educational Effectiveness, 2022
We conducted a randomized control trial assessing the effects of two variants of word-problem intervention with third graders (n = 304) experiencing mathematics difficulty. Students were assigned to a business-as-usual condition (BaU) or one of two variants of word-problem intervention. One variant included a pre-algebraic reasoning component…

Shen, Zuchao; Kelcey, Benjamin – Journal of Research on Educational Effectiveness, 2022
Optimal sampling frameworks attempt to identify the most efficient sampling plans to achieve an adequate statistical power. Although such calculations are theoretical in nature, they are critical to the judicious and wise use of funding because they serve as important starting points that guide practical discussions around sampling tradeoffs and…

Thai, Khanh-Phuong; Bang, Hee Jin; Li, Linlin – Journal of Research on Educational Effectiveness, 2022
This study examines whether "My Math Academy," a digital game-based learning environment that provides personalized content and adaptive embedded assessments, can improve math knowledge of Transitional Kindergarten and Kindergarten students. A cluster randomized study was conducted with 20 classrooms, 10 of which were randomly assigned…

Gray, Abigail M.; Sirinides, Philip M.; Fink, Ryan E.; Bowden, A. Brooks – Journal of Research on Educational Effectiveness, 2022
This study examines the efficacy, cost, and implementation of an integrated science and literacy curriculum for kindergarten. The study was conducted in a large urban district and included 1,589 students in 71 classrooms in 21 schools. The research includes a multi-site cluster-randomized controlled trial and mixed-methods cost and implementation…

Hao, Tao; Wang, Zhe; Ardasheva, Yuliya – Journal of Research on Educational Effectiveness, 2021
This meta-analysis reviewed research between 2012 and 2018 focused on technology-assisted second language (L2) vocabulary learning for English as a foreign language (EFL) learner. A total of 45 studies of 2,374 preschool-to-college EFL students contributed effect sizes to this meta-analysis. Compared with traditional instructional methods, the…

Feller, Avi; Stuart, Elizabeth A. – Journal of Research on Educational Effectiveness, 2021
Panel data methods, which include difference-in-differences and comparative interrupted time series, have become increasingly common in education policy research. The key idea is to use variation across time and space (e.g., school districts) to estimate the effects of policy or programmatic changes that happen in some localities but not others.…

Gao, Niu; Semykina, Anastasia – Journal of Research on Educational Effectiveness, 2021
Inappropriate treatment of missing data may introduce bias into the value-added estimation. We consider a commonly used value-added model (VAM), which includes the past student test score as a covariate. We formulate a joint model of student achievement and missing data, in which the probability of observing a test score depends on observing the…

Kirksey, J. Jacob; Gottfried, Michael A. – Journal of Research on Educational Effectiveness, 2021
Over the past decade, identifying how schools might reduce student absenteeism has moved to the forefront of education policy. Yet little research has examined whether school type itself is important. We focus on the influence of Catholic schools using data from the past decade--the most relevant policy context for addressing absenteeism. The…

de Amesti, José; Claro, Susana – Journal of Research on Educational Effectiveness, 2021
This study estimates the extent to which apprenticeship affects the academic trajectories of vocational high-school students. Previous research has shown that apprenticeship-based high schools (or dual vocational education) increase employment outcomes compared to school-based-only vocational education. Employing a propensity score matching…

Owen, Kaydee L.; Hunter, Stacey H.; Watkins, Richard C.; Payne, Joshua S.; Bailey, Tom; Gray, Cameron; Hastings, Richard P.; Hughes, J. Carl – Journal of Research on Educational Effectiveness, 2021
The Say-All-Fast-Minute-Every-Day-Shuffled (SAFMEDS) strategy promotes fast and accurate recall. The existing literature suggests that the strategy can help learners improve academic outcomes. Through a cluster randomized controlled trial, we assessed the impact of implementation support on children's mathematics outcomes during a teacher-led…

Keele, Luke; Lenard, Matthew; Page, Lindsay – Journal of Research on Educational Effectiveness, 2021
Many interventions in education occur in settings where treatments are applied to groups. For example, a reading intervention may be implemented for all students in some schools and withheld from students in other schools. When such treatments are nonrandomly allocated, outcomes across the treated and control groups may differ due to the treatment…
