This report provides an update on the state of the research on testing accommodations. Previous reports by the National Center on Educational Outcomes (NCEO) have covered research published since 1999. In this report, we summarize the research published in 2019. During 2019, 11 research studies were published on the topic of testing accommodations…

Analyses that reveal how treatment effects vary allow researchers, practitioners, and policymakers to better understand the efficacy of educational interventions. In practice, however, standard statistical methods for addressing Heterogeneous Treatment Effects (HTE) fail to address the HTE that may exist within outcome measures. In this study, we…

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…

Throughout the years, career and technical education (CTE) has focused on teaching technical competencies and related academic skills that prepare students to enter and advance in a variety of career fields and postsecondary education. Program and course descriptions are reviewed on a regular basis to ensure that the technical and academic skills…

Via two reading experiments, this exploratory study examined the effects of over- and under-specified linguistic input on L2 online processing of Chinese referring expressions (REs). In each experiment, a group of advanced L2 Chinese speakers (all with Uyghurs as L1) and a control group of native Chinese speakers read 48 sets of 4 sentence pairs…

Limited access to screening and evaluation for autism spectrum disorder in children is a major barrier to improving outcomes for marginalized families. To identify and evaluate available digital autism spectrum disorder screening resources, we simulated web and mobile app searches by a parent concerned about their child's likelihood of autism…

Differentiated second/foreign language (L2) instruction (DI) has received growing attention in pedagogical research. Yet, as a cornerstone of inclusive education, the DI is still under-documented. In this study, we integrated diagnostic assessment (DIA) and collaborative language learning in a differentiated (tiered) oral tasks intervention and…

It is acknowledged that assessment ethics is an integral part of teacher education. Unlike sizable published research on students' perceptions of assessment in higher education, very little is reported on student teachers' perceptions of assessment ethics across university-based teacher education programs. This study aimed to explore Teaching…

Artificial Intelligence is widely used across contexts and for different purposes, including the field of education. However, a review of the literature showcases that while there exist various review studies on the use of AI in education, missing remains a review focusing on science education. To address this gap, we carried out a systematic…

During the pandemic three widespread shifts in teaching cultures affected digital writing pedagogies: resilient teaching, open teaching, and inclusive teaching. Resilient teaching design emerged as a strategy to counter the unpredictability of public health policies on class delivery modes, and emphasised designing for maximising student…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on reading achievement, as measured by SBA scores. We compared students in schools using i-Ready Personalized Instruction school-wide (Treatment students) to students who only received i-Ready Diagnostic assessments and who were in schools only partially…

This study presents reflections from accounting lecturers in Singapore on the challenges and opportunities of conducting assessments during the crisis period of COVID-19. We seek to answer the following research question: What were the responses of Higher Education Institutions (HEIs) in Singapore to the pandemic to maintain order in the…

Changepoints are abrupt variations in a sequence of data in statistical inference. In educational and psychological assessments, it is pivotal to properly differentiate examinees' aberrant behaviors from solution behavior to ensure test reliability and validity. In this paper, we propose a sequential Bayesian changepoint detection algorithm to…

Initial teacher education programme and paper assessments need to encompass university degree requirements and attest to student mastery of teacher professional competencies. This article reports one aspect of an investigation of the nature and principles employed in the design of assessments for a three-year Bachelor of Teaching (Primary)…

This is the second in a series of five briefs published by the U.S. Department of Education Office of Educational Technology on the key considerations facing educational leaders as they work to build and sustain core digital infrastructure for learning. These briefs offer recommendations to complement the fundamental infrastructure considerations…
