Wang, Mei; Sun, Guangwen; Chang, Yaping; Jin, Yanling; Leenus, Alvin; Maaz, Muhammad; Li, Guowei; Bhatt, Meha; Abbade, Luciana P. F.; Nwosu, Ikunna; Zielinski, Laura; Sanger, Nitika; Bantoto, Bianca; Luo, Candice; Shams, Ieta; Shahid, Hamnah; Adachi, Jonathan; Mbuagbaw, Lawrence; Levine, Mitchell; Samaan, Zainab; Thabane, Lehana – Research on Social Work Practice, 2018
Behavioral and social sciences randomized controlled trials (BSSTs) have a significant role in life sciences. Choosing an appropriate control or comparator group for BSSTs is critical, to provide true intervention effects. The objective of this study was to determine the types of control groups used in BSSTs, and the rationale provided to justify…

Schochet, Peter Z. – Journal of Educational and Behavioral Statistics, 2018
Design-based methods have recently been developed as a way to analyze randomized controlled trial (RCT) data for designs with a single treatment and control group. This article builds on this framework to develop design-based estimators for evaluations with multiple research groups. Results are provided for a wide range of designs used in…

Schochet, Peter – Society for Research on Educational Effectiveness, 2018
Design-based methods have recently been developed as a way to analyze data from impact evaluations of interventions, programs, and policies (Freedman, 2008; Lin, 2013; Imbens and Rubin, 2015; Schochet, 2013, 2016; Yang and Tsiatis, 2001). The non-parametric estimators are derived using the building blocks of experimental designs with minimal…

Fuchs, Lynn S.; Seethaler, Pamela M.; Fuchs, Douglas; Espinas, Daniel – Journal of Learning Disabilities, 2023
Analyses were conducted with second graders, drawn from an ongoing multi-cohort randomized controlled trial (RCT), who had been identified for RCT entry based on comorbid reading comprehension and word-problem solving difficulty. To estimate pandemic learning loss, we contrasted fall performance for 3 cohorts: fall of 2019 (pre-pandemic; n = 47),…

McHugh, Douglas; Feinn, Richard; McIlvenna, Jeff; Trevithick, Matt – Education Sciences, 2021
Learner-centered coaching and feedback are relevant to various educational contexts. Spaced retrieval enhances long-term knowledge retention. We examined the efficacy of Blank Slate, a novel spaced retrieval software application, to promote learning and prevent forgetting, while gathering and analyzing data in the background about learners'…

Isaac M. Opper – Annenberg Institute for School Reform at Brown University, 2021
Researchers often include covariates when they analyze the results of randomized controlled trials (RCTs), valuing the increased precision of the estimates over the potential of inducing small-sample bias when doing so. In this paper, we develop a sufficient condition which ensures that the inclusion of covariates does not cause small-sample bias…

González, Sonia K.; Grov, Christian – Journal of American College Health, 2022
Objective: To evaluate different recruitment methods to enroll participants into a mHealth pilot RCT: banner ads on Facebook and OkCupid, and targeted electronic outreach (e.g., emails to community-based organizations and to professors at local colleges). Participants: Between October 2015 and May 2016, 114 college-aged Black and Latina women 18…

Caroline Botvin; Tyler Watts; Jade Jenkins; Robert Carr; Kenneth Dodge; Douglas Clements; Julie Sarama – Society for Research on Educational Effectiveness, 2022
Background/Context: Early childhood education research has consistently found evidence of immediate, positive effects on developmental outcomes. Despite these strong initial benefits, follow-up analyses often reveal that these effects fadeout in the years following participation (e.g., Bailey et al., 2017, Clements et al., 2013; Lipsey et al.…

Hale, Rebecca – Oxford Review of Education, 2020
It is generally agreed that learning about the Holocaust has some impact on students. However, discussions about the nature and magnitude of impact tend to be intuition-based rather than evidence-based. This is exacerbated by studies giving insight into how Holocaust education is related to salient variables rather than studies which demonstrate…

Norwich, Brahm; Koutsouris, George – International Journal of Research & Method in Education, 2020
This paper describes the context, processes and issues experienced over 5 years in which a RCT was carried out to evaluate a programme for children aged 7-8 who were struggling with their reading. Its specific aim is to illuminate questions about the design of complex teaching approaches and their evaluation using an RCT. This covers the early…

Moustgaard, Helene; Jones, Hayley E.; Savovic, Jelena; Clayton, Gemma L.; Sterne, Jonathan AC; Higgins, Julian PT; Hróbjartsson, Asbjørn – Research Synthesis Methods, 2020
Randomized clinical trials underpin evidence-based clinical practice, but flaws in their conduct may lead to biased estimates of intervention effects and hence invalid treatment recommendations. The main approach to the empirical study of bias is to collate a number of meta-analyses and, within each, compare the results of trials with and without…

Jaylin Lowe; Charlotte Z. Mann; Jiaying Wang; Adam Sales; Johann A. Gagnon-Bartsch – Grantee Submission, 2024
Recent methods have sought to improve precision in randomized controlled trials (RCTs) by utilizing data from large observational datasets for covariate adjustment. For example, consider an RCT aimed at evaluating a new algebra curriculum, in which a few dozen schools are randomly assigned to treatment (new curriculum) or control (standard…

Cartwright, Nancy – Educational Research and Evaluation, 2019
Across the evidence-based policy and practice (EBPP) community, including education, randomised controlled trials (RCTS) rank as the most "rigorous" evidence for causal conclusions. This paper argues that that is misleading. Only narrow conclusions about study populations can be warranted with the kind of "rigour" that RCTs…

Fujiki, Robert Brinton; Oliver, Abby J.; Sivasankar, M. Preeti; Craig, Bruce A.; Malandraki, Georgia A. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The aim of this study was to investigate secondary voice outcomes and detraining effects of 2 head and neck strengthening exercises, which have been used in swallowing rehabilitation, that is, the head-lift exercise (HLE) and the recline exercise (RE), in healthy older adults. Method: Twenty-seven healthy older adults (between 60 and 85…

Gelfand, Scott D. – Research Ethics, 2019
In this essay, I suggest that a slightly modified version of Freedman's formulation of the clinical equipoise requirement is justified. I begin this essay with a brief discussion of the equipoise requirement. In the second and third sections, I discuss several objections to the clinical equipoise requirement as well as two attempts to justify the…
