Purpose: This article aims to investigate the impact of the Lesson Study (LS) model on students' mathematics achievement and attitudes toward mathematics. Design/methodology/approach: The study employs a concurrent embedded design, a type of mixed methods design. Within this framework, a quantitative pretest-posttest control group…

Outdoor environmental education programs frequently aim to influence participants' environmental values and behaviors. Published studies have frequently documented their success in doing so. However, few studies have examined the characteristics of programs in relation to accomplishing those goals. Using characteristics identified as important in…

The Assessment-to-Instruction (A2i) Professional Support System has been shown to be effective in improving literacy proficiency among young readers by combining data-driven technology with professional development (PD) activities to help teachers provide personalized literacy instruction. To identify efficient ways to expand the reach of A2i,…

The primary purpose of this study was to examine the effects of providing mindset intervention in addition to reading intervention compared with only reading intervention for fourth graders with reading difficulties. Reading intervention was provided daily in 45 min sessions throughout the school year. Mindset intervention occurred in small groups…

This quantitative causal-comparative study investigated the growth performance scores of English learners in grades three through five in reading, mathematics, and science in four English language educational programs: English as Second Language (ESL), Transitional Bilingual Education (TBE), Dual-Language Immersion (DLI), and No Services. I used…

A Word Problem Enrichment programme (WPE) has been found to increase student word problem solving performance when facing non-routine and application problems. However, it is unknown if the WPE has an impact on student beliefs about word problem solving and how the WPE works for students with different motivation in learning mathematics. This…

Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

This research sought to uncover challenges that arose in the implementation of the Reflective Educational Approach to Character and Health (REACH) after-school programme in a low-income public school in New York City. Additionally, we wanted to find and share some of the lessons learned, to help others avoid our pitfalls when implementing quality…

Social skills training programs have increasingly enlisted same-age typical peers as instructors in the teaching of social skills to children with high-functioning autism spectrum disorder (ASD). The inclusion of peers in the teaching process has been found to be a critical component in these programs. Despite strong support for incorporating…

The Tactical Games Model (TGM) prefaces the cognitive components of physical education (PE), which has implications for physical activity (PA) accumulation. PA recommendations suggest students reach 50% moderate-vigorous physical activity (MVPA). However, this criterion does not indicate the contribution from vigorous physical activity (VPA).…

This study investigates school effects on primary school students' language and mathematics achievement trajectories in Chile, a context of particular interest given its large between-school variability in educational outcomes. The sample features an accelerated longitudinal design (3 time points, 4 cohorts) together spanning Grades 3 to 8…

Charter schools--public schools that receive greater autonomy from district and state regulations in return for greater accountability--present opportunities to provide exemplary and innovative supports and services to students with disabilities. Charter schools' freedom to innovate enables them to create and offer new models and practices, which…

This applied dissertation was designed to provide perceptual teacher data as well as summative testing data to educational leaders concerning the effects of implementing Investigations in Number, Data, and Space® (Investigations) in three Title I elementary school settings, two Title I schools, and one non-Title I school. Data collected during…

This experimental study examines the effects of Integrated Curriculum Model (ICM) on 4th grade elementary gifted and talented students' academic achievement, creativity and critical thinking (Control Group N= 10, Experimental Group N= 11) in the social studies classroom context, in Istanbul, Turkey. Integrated Curriculum Model was utilized to…

There is little discussion in the Design-Based Research (DBR) literature on how to design an intervention that has the potential to be highly effective. The act of designing is usually viewed as engineering something from theory or research on best practices. This paper challenges that universal belief and presents successful design as an…
