Several branches of the potential outcome causal inference literature have discussed the merits of blocking versus complete randomization. Some have concluded it can never hurt the precision of estimates, and some have concluded it can hurt. In this article, we reconcile these apparently conflicting views, give a more thorough discussion of what…

This article describes our efforts to screen and enrol clinical trial participants conscientiously in the COVID-19 pandemic setting. We present the standard screening and enrolment process prior to, and our process of adapting to, the pandemic. Our goal was to develop a way to screen and enrol people for clinical trials that was both equitable and…

Although most individuals experience expectation violations in their educational years, individuals' coping strategies differ depending on situational and dispositional characteristics with potentially decisive influence on educational outcomes. As a situational characteristic, optimism bias indicates that individuals tend to update their…

Pregnancy is a frequently applied exclusion criteria for many forms of research. Common justifications for this exclusion include the potential for teratogenicity, as well as the potential for physiologic changes in pregnancy to impact the research itself. The systematic exclusion of pregnant persons from clinical studies has created a significant…

Strategy interventions have been found to support students' text comprehension, but little is known about the sustainability of these effects. This study examined short- and long-term effects of a strategy intervention on students' vocabulary and text comprehension at the literal, inferential and evaluative levels. A pretest, posttest, and…

Developmental disabilities (DD) research has depended on volunteer and clinical samples, with limited racial/ethnic diversity. This study focused on improving diversity and retention in DD research. The sample included 225 parents with a child with DD and 4,002 parents without children with DD from diverse racial/ethnic groups, drawn from Midlife…

Systematic reviewers are advised to search trials registers to minimise risk of reporting biases. However, there has been little research on the impact of searching trials registers on the results of meta-analyses. We aimed to evaluate the impact of searching clinical trials registers for systematic reviews of pharmaceutical or non-pharmaceutical…

Searching for trials is a key task in systematic reviews and a focus of automation. Previous approaches required knowing examples of relevant trials in advance, and most methods are focused on published trial articles. To complement existing tools, we compared methods for finding relevant trial registrations given a International Prospective…

Background: In the modern music industry, AI music generators have gained particular importance. The use of AI greatly simplifies the creation of polyphony. In addition, it can increase student motivation and interest. Aims: This study focuses on the AI-assisted creation of polyphonic music. The purpose of this study is to determine how creating…

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…

In this research, a GAmified Mobile Leaning Framework (GAMOLEAF) developed as a new intelligent application designed for mobile devices to ensure learning, assessing, and advancing learners' knowledge in programming complex data structures in Java programming language. GAMOLEAF adopted motivational strategies to solve motivational problems during…

To assist preservice elementary teachers in attaining scientific competence, knowledge, and understanding of interdisciplinary concepts, a teacher education model--the combined individual microteaching, modeled teaching, and inquiry-based team-teaching (CIMIT) model--was established, and its effectiveness was evaluated. A quasiexperimental design…

In the area of online teacher training, asynchronous collaboration faces several challenges such as limited learner engagement and low interaction quality, thereby hindering its overall effectiveness. Drawing on social comparison theory, providing social comparison feedback to teacher-learners in online asynchronous collaborative learning offers…

The State NAEP program only reports the mean achievement estimate of a subgroup within a given state if it samples at least 62 students who identify with the subgroup. Since some subgroups of students constitute small proportions of certain states' general student populations, these low-incidence groups of students are seldom sufficiently sampled…

This study adopted integrated cooperative learning and writing-to-learn activities rather than the traditional approach to having preservice science teachers acquire knowledge about classroom management. The effects of these practices were compared. This research aims to determine the effects of cooperative news articles and story writing, as well…
