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…

Existing systems for automating the assessment of risk-of-bias (RoB) in medical studies are supervised approaches that require substantial training data to work well. However, recent revisions to RoB guidelines have resulted in a scarcity of available training data. In this study, we investigate the effectiveness of generative large language…

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…

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…

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…

This study examined the impacts of internationalization-at-home efforts on intercultural interactions and outcomes for domestic graduate students through a Cultural Partner Program. Ninety-seven participants were recruited from a public research university in the southeastern part of the U.S. Among them, 68 participated in an experimental group in…

In recent years, children and adolescents have spent more time sitting and engaging in less physical activity than recommended by health authorities. Despite widespread efforts to promote physical activity through school-based programs, the impact of specific intervention programs often remains untested. Therefore, in this pilot study, the effects…

Self-cognition and self-acceptance are essential for mental health development and emotion in college students. The study investigated the efficacy of group drawing therapy in improving Chinese college students' positive self-cognition and self-acceptance. It is worth noting that Chinese college students in a collectivist culture have systematic…

This study reports the results of a multi-site, parallel block randomized clinical trial to expand the previous findings regarding the implementation of Project SEARCH plus ASD Supports (PS + ASD) on employment outcomes upon graduation from high school. Participants were 156 individuals with significant impact from ASD between the ages of 18-21.…

We present experimental evidence on the impact of a multi-faceted program that integrates technology-aided instruction, teacher training and coaching, community ownership, and free primary education. Our setting is three districts in rural Zambia, where we randomly assigned the program across 30 treatment and 33 control schools. The results show…

This study developed an online role-playing history education game with real-person NPCs (Non-Player Characters). The game features real people playing NPC characters, and provides a multi-dimensional scaffolding mechanism with realistic story and historical scenes, allowing learners to engage in strategic planning and problem solving during a…

Via AI video generators, it is possible to create educational videos with humanistic instructors by simply providing a script. The characteristics of video types and features of instructors in videos impact video engagement and, consequently, performance. This study aimed to compare the impact of human instructors and AI-generated instructors in…
