Introduction: For tests reporting continuous results, primary studies usually provide test performance at multiple but often different thresholds. This creates missing data when performing a meta-analysis at each threshold. A standard meta-analysis (no imputation [NI]) ignores such missing data. A single imputation (SI) approach was recently…

Moving freight to sustainable transport modes is one of the most frequently mentioned suggestions to decarbonize logistics. Regrettably, even with regulation and technology developing over the past years, most of the freight volumes are still shipped via road, the least sustainable means of transport. This paper presents a beer transportation game…

Individuals who engage in aggression often display precursors or agitated behavior first, and it is important for caregivers to learn how to minimize risk of injury in the event that aggression were to occur. In this study, behavioral skills training was used to teach 4 caregivers of children who engage in aggression to position their body safely…

This study explored how scientific ideas interacted in college students' scientific explanations using text analysis techniques and network analysis. A task was given to first-year college students asking them to answer a series of physics questions associated with a computer simulation. Students' written responses were classified into three…

This study develops a framework to conceptualize the use and evolution of machine learning (ML) in science assessment. We systematically reviewed 47 studies that applied ML in science assessment and classified them into five categories: (a) constructed response, (b) essay, (c) simulation, (d) educational game, and (e) inter-discipline. We compared…

Rater fit analyses provide insight into the degree to which rater judgments correspond to expected properties, as defined within a measurement framework. Parametric models such as the Rasch model provide a useful framework for evaluating rating quality; however, these models are not appropriate for all assessment contexts. The purpose of this…

Purpose: The present study aims to evaluate how the reliabilities computed using a, Stratified a, Angoff-Feldt, and Feldt-Raju estimators may differ when sample size (500, 1000, and 2000) and item type ratio of dichotomous to polytomous items (2:1; 1:1, 1:2) included in the scale are varied. Research Methods: In this study, Cronbach's a,…

Teaching writing strategies based on writing processes has attracted wide attention as a method for developing writing skills. The writing process can be generally defined as a sequence of subtasks, such as planning, formulation, and revision. Therefore, instructor feedback is often given based on sequence patterns of those subtasks. For such…

This research examines small group collaboration on the Augmented Reality (AR) Sandbox, an interactive, real-time topographical simulator that provides a color layer of augmentation showing depths and height, contour lines, and hydrology vis-a-vis the terrain of sand in a box. Prior research has focused on AR Sandbox activity designs, outcome…

In random-effects meta-analysis the between-study variance ([tau][superscript 2]) has a key role in assessing heterogeneity of study-level estimates and combining them to estimate an overall effect. For odds ratios the most common methods suffer from bias in estimating [tau][superscript 2] and the overall effect and produce confidence intervals…

This paper considers the problem in aggregate data meta-analysis of studies reporting multiple competing binary outcomes and of studies using different summary formats for those outcomes. For example, some may report numbers of patients with at least one of each outcome while others may report the total number of such outcomes. We develop a shared…

Existing literature regarding social communication outcomes of interventions in autism spectrum disorder (ASD) depends upon human raters, with limited generalizability to real world settings. Technological innovation, particularly virtual reality (VR) and collaborative virtual environments (CVE), could offer a replicable, low cost measurement…

The rapid and ongoing development of digital technologies continues to create new opportunities for education. Over the last decade this has enabled the establishment of blended learning approaches and online education. More recently, Augmented Reality (AR) has emerged as a unique technology that can transform learning experiences across diverse…

Reflection plays an important role in medical students' ability to develop diagnostic competence through practice with clinical cases. However, it is not easy for students to develop expert-like performance through self-reflection alone; conversely, seeking feedback from experts constantly in practice is impractical. This study investigates the…

Computer simulation can be used to demonstrate why the unbiased sample variance uses degrees of freedom (n-1). This is first demonstrated for sampling from a normal random variable, and in additional simulations for some selected non-normal random variables, namely, chi-square and binomial.
