This research applied a web-based dynamic assessment system, GPAM-WATA system, to help low English achievers to perform self-directed learning of junior high school English grammar. A quasi-experimental design was adopted. A total of 124 seventh graders from four classes participated in this research. Participants were randomly divided into the…

Implementing a randomized controlled trial design, the present study investigated the effects of two types of accommodations, linguistic modification and a glossary, for English learners (ELs) taking a computer-based mathematics assessment. Process data including response time and clicks on glossary words were also examined to better interpret…

Primary school students of the digital generation often struggle to maintain motivation and engagement, especially under static and non-interactive teaching strategies, underscoring the need for more effective educational approaches. This quasi-experimental study examined whether integrating a gamified interactive response system, Blooket, into a…

This study examines the relationships between three accommodation strategies--Extended Time (ET) only, breaks only, and breaks bundled with ET--and academic performance, test-taking behavior, and attitudes among eighth-grade students with disabilities who participated in the 2017 National Assessment of Educational Progress (NAEP) mathematics…

Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

The Gifted and Talented program in New York City is one of the largest and longest running programs for gifted students in the nation. Yet little is known about its effects on student outcomes. Using student-level administrative data of New York City public school students between the 2010--2011 and 2018-2019 academic years, we studied the effects…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

Background: Most United States schools include school-based physical fitness testing (SB-PFT), yet little evidence shows how it is implemented, perceived, and used. Purpose: 1) Explore stakeholders' experiences with SB-PFT; 2) identify: challenges in analyzing fitness data, ways schools can use fitness data, and predictors of meeting fitness…

Previous research illustrated that reading comprehension and science performance correlate highly. Because students with specific learning disorders with impairments in reading (SLD-IR) show deficits in reading comprehension, they may struggle to perform in science. As language in science is characterized by linguistic complexity, the question…

As the youth mental health crisis continues to worsen, there is a need for more evidence-based social-emotional interventions that can be applied in schools -- the setting in which youth are most likely to seek and receive mental health treatment (Simon et al., 2015). Further, exploring ways to culturally adapt interventions for marginalized…

Making causal inferences from a quasi-experiment is difficult. Sensitivity analysis approaches to address hidden selection bias thus have gained popularity. This study serves as an introduction to a simple but practical form of sensitivity analysis using Monte Carlo simulation procedures. We examine estimated treatment effects for a school-based…

Students with autism may struggle to develop the academic skills necessary for success in school and beyond. Understanding and improving academic skills performance requires appropriate measurement approaches. One such option that has been minimally studied with students with autism is curriculum-based measurement (CBM). Coinciding with the need…

This study investigated the effects of Plickers use on rural students' learning outcomes through two case scenarios. In the first case scenario, the study adopted a preexperimental study method with a focus on comparing Plickers with traditional testing to examine rural students' learning attitudes toward Plickers. The participants were 24…

School closures induced by COVID-19 placed heightened emphasis on alternative ways to measure student learning besides in-person exams. We leverage the administration of phone-based assessments (PBAs) measuring numeracy and literacy for primary school children in Kenya, along with in-person standardized tests administered to the same students…

In 1984 Benjamin Bloom stated that one-to-one tutorial support increased students' achievement by two standard deviations (two sigma problem). In the literature for solving two sigma problem (in order to increase student achievement), many systems were developed as intelligent tutoring systems, adaptive hypermedia systems, recommender systems and…
