This paper examines the scalability of the results from the Tennessee Student-Teacher Achievement Ratio (STAR) Project, a prominent educational experiment. We explore how the misalignment between the experimental design and the econometric model affects researchers' ability to learn about the intervention's scalability. We document heterogeneity…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of initial variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

Mathematics is, universally, considered the heartbeat of the Science, Technology, Engineering and Mathematical (STEM) education. Accordingly, the learners must be equipped with strong mathematical proficiency very early in life. This behoves mathematics practitioners to use various impactful pedagogical strategies. The bigger action research from…

In today's interconnected world, cross-cultural competence is essential for students' success. This article investigates how educational interventions foster this crucial skill. Using a mixed-meta research method, the study combines a meta-analysis of 16 quantitative studies (12,800 participants) with a meta-thematic analysis of 7 qualitative…

This study examined whether the efficacy of ROOTS, a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, differed by group size and whether initial skill moderated intervention effects by group size. The study utilized a randomized block design with at-risk students (n = 1,251) within…

This study examined whether the efficacy of a 50 lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, ROOTS, differed by group size and whether initial skill moderated intervention effects by group size. The study utilized a randomized block design with at-risk students (n = 1,251) within…

Transition to kindergarten is an important developmental milestone for children and families. This study explored factors associated with kindergarten readiness focusing on the impact of a summer kindergarten transition program. A mixed-method design was employed, and the qualitative data from interviews with 16 randomly selected kindergarten…

In an effort to reduce viral transmission, many schools are planning to reduce class size if they have not reduced it already. Yet the effect of class size on transmission is unknown. To determine whether smaller classes reduce school absence, especially when community disease prevalence is high, we merge data from the Project STAR randomized…

Persuasive Technologies (PT) are computational methods, strategies, and design techniques, grounded in social psychology to change user attitudes/behaviours. PTs have been applied in diverse areas, such as eCommerce, health, workplace, vehicles, urban and ambient environments. A kind of PT that has become popular in eLearning is known under the…

Previous research exploring the lived experiences of marginalized groups of students in STEM at community college settings is limited, despite the fact that community colleges have the potential to create pathways to 4-year engineering degrees and diversify the STEM workforce. This study explored what underrepresented students in STEM valued most…

The purpose of this study was to evaluate the effects of an 18-day summer tutoring program in which graduate student tutors delivered 15 minutes of differentiated reading instruction (DRI) and a 30-minute interactive read-aloud (IRA) lesson each day. Students in grades K-5 (N = 179) attending a summer program at one urban elementary school…

The purpose of this research was to conduct an analysis of the challenges faced in the teaching and learning of Textiles in the primary school curriculum in Masvingo district Zimbabwe. The study was informed and guided by two theories namely the concernsbased adoption model (CBAM) and the pragmatist's theory. A qualitative case study design was…

Teachers face increased workplace challenges in South Africa. Through a process of intervention research, this study aimed to develop and evaluate the efficacy of a work-based support programme for teachers. Maslow's hierarchy of needs was adopted as the theoretical framework informing both programme design and evaluation. Teachers (n = 10) were…

This study deviates from the standard view of template-based training courses that have dominated the experience of in-service English teachers in Ecuador. Its purpose is to underscore the contextualization of training modules as a strategic method for duplicating and scaling up multi-level teacher training to sustain their knowledge and skills.…
