Evidence-based medicine (EBM) is helpful for laypersons' decision-making. This study aimed to evaluate the effectiveness of e-learning materials on the essential components of EBM for laypersons. We conducted a web-based, open-label, randomized controlled trial with laypersons in Japan aged [greater than or equal to]20 years who used the internet.…

Tender Shoots is a randomized controlled trial (RCT) for parents aimed at improving preschool children's oral language skills relevant for later reading. Parents of 72 preschool children (M = 50 months) were randomly assigned to either a Rich Reading and Reminiscing (RRR) condition, a Strengthening Sound Sensitivity (SSS) condition, or an…

The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

The chest X-ray is the most commonly performed medical imaging study; however, the lateral chest film intimidates many physicians and medical students. The lateral view is more difficult to interpret than the frontal view but provides important information that is either not visible or not as evident on frontal view, and inability to read it may…

An impediment to conducting high-quality quantitative research studies in education is the paucity of valid measures of learning gains. Studies often seek to investigate students' deep, conceptual understanding yet many measures assess only surface, procedural understanding. One reason is that the development of validated measures of conceptual…

A randomized controlled trial was conducted to determine the efficacy of "U-Pace" instruction for older undergraduates, ages 25 and older, and younger undergraduates, ages 18 to 24. Additionally, change in learner perceptions across the semester, an outcome not reported in the literature on "U-Pace" instruction, was…

Many instructors in science, technology, engineering, and mathematics fields are striving to create active learning environments in their classrooms and in doing so are frequently moving the lecture portion of their course into online video format. In this classroom-based study, we used a two group randomized experimental design to examine the…

Simulation technology in healthcare education is continuously evolving but little is known about the effects of high fidelity simulation on student knowledge and skill retention or motivation. The purpose of this quantitative study was to use quasi-experimental design in a randomized controlled trial that compared the retention of knowledge and…

Many college students never take, or do not pass, required remedial mathematics courses theorized to increase college-level performance. Some colleges and states are therefore instituting policies allowing students to take college-level courses without first taking remedial courses. However, no experiments have compared the effectiveness of these…

A randomized controlled trial was used to evaluate the impact of a frequency-building curriculum to increase the fluency of component mathematics skills in a sample of 28 males aged 9-11 years. Assessments of mathematical ability were conducted before and after the training period to evaluate the impact of learning component skills fluently on…

In this article, we discuss research supporting the Strategic Instruction Model's™ (SIM) effort to address higher order reasoning and thinking skills in two lines of programmatic research. We review the extant body of evidence supporting the two lines of the SIM library, the Content Enhancement Routines and a comprehensive reading program, and the…

Despite recent interest in flipped classrooms, rigorous research evaluating their effectiveness is sparse. In this study, the authors implement a randomized controlled trial to evaluate the effect of a flipped classroom technique relative to a traditional lecture in an introductory undergraduate econometrics course. Random assignment enables the…

Community colleges are a large sector of postsecondary education. In 2016-2017, the United States had nearly 1,000 public 2-year postsecondary institutions (community colleges), serving almost nine million students, representing 39% of all undergraduates. The majority of entering community college students require developmental (or remedial) math.…

In this paper we evaluate the effectiveness of an adaptive online learning platform, designed to support Chinese students in learning the English language. The adaptive platform is studied in three studies, where the experimental platform is compared to an alternate, non-adaptive platform, with random assignment to conditions (the adaptive…

Beginning in 2002, researchers developed, implemented, and evaluated the efficacy of an English reading intervention for first-grade English learners using multiple randomized control trials (RCTs). As a result of this efficacy work, researchers successfully competed for an IES Goal 4 effectiveness study using the same intervention. Unlike the…
