Telehealth training may benefit parents' use of early intervention for children with autism spectrum disorder (ASD). This study is one of the few randomized trials to compare telehealth parent training in the Early Start Denver Model (P-ESDM) with a community treatment-as-usual, early intervention program. Parents were randomized to 12 weekly…

A randomized controlled trial was conducted to evaluate effects of the Joint Attention Mediated Learning (JAML) intervention. Toddlers with autism spectrum disorders (ASD) aged 16-30 months (n = 144) were randomized to intervention and community control conditions. Parents, who participated in 32 weekly home-based sessions, followed a mediated…

Background: Dysphagia is common after stroke, affecting up to 50% of patients initially. It can lead to post-stroke pneumonia, which causes 30% of stroke-related deaths, a longer hospital stay and poorer health outcomes. Dysphagia care post-stroke generally focuses on the management of symptoms, via modified oral intake textures and adapted…

Objective: To determine the feasibility of a mobile health (mHealth), media literacy education program, "Media Aware", for improving sexual health outcomes in older adolescent community college students. Participants: 184 community college students (ages 18-19) participated in the study from April-December 2015. Methods: Eight community…

"U-Pace" instruction, comprised of concept mastery and amplified assistance, has shown promise in increasing undergraduate success. To evaluate the efficacy of "U-Pace" instruction for students at risk for college noncompletion and students not at risk and to determine whether concept mastery, amplified assistance, or both…

The purpose of the study was to conduct a randomized controlled trial (RCT) to demonstrate efficacy of the Class-wide Function-Related Intervention Teams (CW-FIT) program. The study was designed to replicate an initial RCT conducted by the CW-FIT developers in 1 site, with 2 additional research groups not involved in its development. The study was…

This article reports the results of a randomized control trial of a semester-long intervention designed to promote ninth-grade science students' use of text-based investigation to create explanatory models of biological phenomena. The main research question was whether the student participants in the intervention outperformed the students in the…

We report here the type of problems and solutions that 38 school teams reported during a randomized wait-list controlled trial of one problem-solving approach (Team Initiated Problem Solving [TIPS]). The experimental results from that analysis are reported elsewhere. The purpose of this article is to summarize companion descriptive data from this…

Despite research demonstrating the importance of student-teacher relationships for student functioning, little is known about strategies to enhance such relationships, particularly in secondary school. The current study examined effects of a professional development for middle school teachers on the Establish-Maintain-Restore (EMR) approach. EMR…

A common design in education research for interventions operating at a group or cluster level is a cluster randomized trial (CRT) (Bloom, 2005). In CRTs, intact clusters (e.g., schools) are assigned to treatment conditions rather than individuals (e.g., students) and are frequently an effective way to study interventions because they permit…

This case describes a current evaluation of an educational intervention to help disadvantaged children catch up in literacy at around the time they transfer to their senior school. The evaluation is based on a randomised controlled trial design, which the case explains is the most appropriate for testing or establishing a causal claim. The case…

Learning disability (LD) identification has long been controversial and has undergone substantive reform. This study examined the consistency of school psychologists' LD identification decisions across three identification methods and across student evaluation data conclusiveness levels. Data were collected from 376 practicing school psychologists…

This article discusses the nonuse, misuse, and proper use of pilot studies in experimental evaluation research. The authors first show that there is little theoretical, practical, or empirical guidance available to researchers who seek to incorporate pilot studies into experimental evaluation research designs. The authors then discuss how pilot…

Background: Interventions found to be effective in research settings are often not as effective when implemented in community settings. Considering children with autism, studies have rarely examined the efficacy of laboratory-tested interventions on child outcomes in community settings using randomized controlled designs. Methods: One hundred and…

We develop a theoretical and empirical basis for the design of teacher professional development studies. We build on previous work by (a) developing estimates of intraclass correlation coefficients for teacher outcomes using two- and three-level data structures, (b) developing estimates of the variance explained by covariates, and (c) modifying…
