Ferjan Ramírez, Naja; Lytle, Sarah Roseberry; Fish, Melanie; Kuhl, Patricia K. – Developmental Science, 2019
Previous studies reveal an association between particular features of parental language input and advances in children's language learning. However, it is not known whether parent coaching aimed to enhance specific input components would (a) successfully increase these components in parents' language input and (b) result in concurrent increases in…

Gao, Furong; Li, Jiao; Xu, Jie; Jia, Song; Xu, Lei; Li, Siguang; Xu, Guo-Tong; Lu, Lixia – Biochemistry and Molecular Biology Education, 2019
Recently, Chinese medical education has exhibited a shifting trend from teacher-centered instruction to student-centered learning, which usually includes a self-directed learning process. Providing students with high-quality and appropriate supplemental resources is necessary for their self-directed learning. This study aimed to investigate the…

Freeman, Suzanne C.; Carpenter, James R. – Research Synthesis Methods, 2017
Network meta-analysis (NMA) combines direct and indirect evidence from trials to calculate and rank treatment estimates. While modelling approaches for continuous and binary outcomes are relatively well developed, less work has been done with time-to-event outcomes. Such outcomes are usually analysed using Cox proportional hazard (PH) models.…

Henley, Amy J.; Hirst, Jason M.; DiGennaro Reed, Florence D.; Becirevic, Amel; Reed, Derek D. – Analysis of Verbal Behavior, 2017
This study evaluated the effects of four instructional variants on instruction following under changing reinforcement schedules using an operant task based on Hackenberg and Joker's "Journal of the Experimental Analysis of Behavior," 62, 367-383 (1994) experimental preparation. Sixteen college-aged adults served as participants and were…

Pearl, Judea – Sociological Methods & Research, 2017
We address the task of determining, from statistical averages alone, whether a population under study consists of several subpopulations, unknown to the investigator, each responding to a given treatment markedly differently. We show that such determination is feasible in three cases: (1) randomized trials with binary treatments, (2) models where…

Lohr, Sharon L.; Zhu, Xiaoshu – Sociological Methods & Research, 2017
Many randomized experiments in the social sciences allocate subjects to treatment arms at the time the subjects enroll. Desirable features of the mechanism used to assign subjects to treatment arms are often (1) equal numbers of subjects in intervention and control arms, (2) balanced allocation for population subgroups and across covariates, (3)…

Milburn, Trelani F.; Lonigan, Christopher J.; Phillips, Beth M. – Elementary School Journal, 2017
This response to intervention study examined agreement between classification methods of preschool children's responsiveness to Tier 2 intervention using level of performance (25th percentile), growth (equivalent to small and medium effect sizes), and both level of performance and growth in a dual-discrepancy approach. Overall, 181 children…

Welch, Vicki; Turner-Halliday, Fiona; Watson, Nicholas; Wilson, Philip; Fitzpatrick, Bridie; Cotmore, Richard; Minnis, Helen – International Journal of Social Research Methodology, 2017
Obtaining informed consent can be challenging in stressful and urgent circumstances. One example is when potential participants have recently had their child removed into care; intervention is urgent and mandatory whereas participation in associated research is voluntary. Using a nested qualitative study, we examined experiences of consent…

What Works Clearinghouse, 2017
"Attrition" is the loss of sample during the course of a study. It occurs when individuals initially randomly assigned in a study are not included when researchers examine the outcome of interest. Attrition is a common issue in education research, and it occurs for many reasons. The What Works Clearinghouse (WWC) is an initiative of the…

Chan, Wendy – AERA Online Paper Repository, 2017
Policymakers are increasingly interested in the extent to which experimental results generalize from a sample to a population of inference. When the sample is not randomly selected, propensity score methods are used to reweight the sample. Subclassification by propensity score is commonly used in which the population is partitioned into strata…

Weiss, Michael J.; Scrivener, Susan; Slaughter, Austin; Cohen, Benjamin – Educational Evaluation and Policy Analysis, 2021
Most community college students are referred to developmental education courses to build basic skills. These students often struggle in these courses and college more broadly. CUNY Start is a prematriculation program for students assessed as having significant remedial needs. CUNY Start students delay matriculation for one semester and receive…

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC[subscript 2010] mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy…

The present study examined whether, when, and how motivational messaging can boost the response rate of postal surveys for physicians based on Higgin's regulatory focus theory, accounting for its cost-effectiveness. A three-arm, blinded, randomized controlled design was used. A total of 3,270 doctors were randomly selected from the registration…

Kelley, Elizabeth; Leary, Emily; Goldstein, Howard – Journal of Speech, Language, and Hearing Research, 2018
Purpose: To effectively implement a response to intervention approach, there is a need for timely and specific information about student learning in response to treatment to ensure that treatment decisions are appropriate. This exploratory study examined responsivity to a supplemental, Tier 2 vocabulary intervention delivered to preschool children…
