Purpose: Grounded in the trans-contextual model of motivation framework, this cluster-randomized trial examined the effectiveness of an autonomy supportive physical education (PE) instruction on student motivation and physical activity (PA). Method: The study comprised six middle schools and 408 students (M[subscript age] = 12.29), with primary…

This study employed group randomized trials to investigate the effects of self- and peer-monitoring on the academic vocabulary and content knowledge of students with learning disabilities and low achieving students in social studies. Fourth grade students were randomly assigned to either treatment or control groups on a class level. Results…

Reading skills and social-emotional competencies are two important skills for both academic achievement and long-term quality of life. The present study evaluated the effects of a school-based intervention to promote reading skills and social-emotional competencies in young adolescents from urban, low socioeconomic status (SES) communities in…

This article aims to investigate the reliability and validity of the Trait Emotional Intelligence Questionnaire-Adolescent Short Form (TEIQue-ASF) score in a sample of 440 Greek adolescents. The instrument's score demonstrated good internal consistency and was significantly correlated with core self-evaluations as well with somatic complaints,…

The purpose of this study was to compare the acute effects of Aerobic Exercise (AE), Resistance Exercise (RE), and a nonexercise (NE) control on measures of academic achievement (AA) and cognition in 10th grade males and females. This study utilized a randomized crossover design. Tenth grade males and females performed three exercise trials (AE,…

The aim of the study was to conduct a comparative analysis of three forms of knowledge transfer online, taking into account the long-term knowledge growth rate and the satisfaction of students surveyed in respect to distance learning. The cohort of participants for this survey were students of the first degree, studying in the Emergency Medical…

This paper reports a pilot study to determine the potential impact of an integrated STEM curriculum on Pre-K teachers' engineering content knowledge, self-efficacy and teaching practice. Using a randomized control trial design, researchers examined the impact of the curriculum in 17 Pre-K classrooms (8 intervention classrooms, 9 control…

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 growing body of research exists on the effectiveness of classroom-based intervention programs to prevent and ameliorate social, emotional, and learning difficulties demonstrated by young children at risk for emotional and behavioral disorders (EBD). Yet, little research has examined the influence of these targeted intervention programs on the…

We assessed the efficacy of an individual-based behavioral intervention on sexually transmitted infections' (STI) risk-reduction behaviors in Singapore. A randomized controlled trial of a behavioral intervention compared to usual care was conducted on sexually active heterosexual adolescents aged 16-19 years attending the only public STI clinic.…

There's a strong case for making social and emotional learning (SEL) skills and competencies a central feature of elementary school. Children who master SEL skills get along better with others, do better in school, and have more successful careers and better mental and physical health as adults. Evidence from the most rigorous studies of…

This study addressed whether providing mothers and children with engineering information would promote science, technology, engineering, and mathematics (STEM) talk during interactions in a building-construction exhibit and later when remembering the experience at home. A total of 40 mothers and their 5- to 6-year-old children (M = 5.87) were…

Few evidence-based practices, defined as the use of empirically supported research and clinical expertise for children with autism, have been successfully implemented and sustained in schools. This study examined the perspectives of school personnel (n = 39) on implementing a social engagement intervention for children with autism. Semi-structured…

Theoretically, interventions initiated with at-risk infants prior to the point in time a definitive autism spectrum disorder (ASD) diagnosis can be made will improve outcomes. Pursuing this idea, we tested the efficacy of a parent-mediated early intervention called Adapted Responsive Teaching (ART) via a randomized controlled trial with 87…

The authors recently conducted a randomized controlled trial that showed a significant impact of teachers' lesson study, supported by mathematical resources, on both teachers' and students' understanding of fractions. The research and mathematical resources are described in the second part of this article. First the authors examine some of the…
