Assessment is an essential part of teaching and learning, but too often it leads to misleading conclusions--sometimes with dire consequences for students. How can educators improve assessment practices so that the results are accurate, meaningful, informative, and fair? Educator and best-selling author Myron Dueck draws from his firsthand…

The Performance Evaluation Reform Act (PERA) has been the governing legislation for teacher evaluation in Illinois since its inception in 2010. PERA's original purpose was to improve the professional competence of teachers while increasing the academic performance of students. This study explored the perceptions and experiences of a small group of…

This causal-comparative quantitative study investigated the effects of dual-language immersion programs on reading and math achievement for non-English learner (EL) students that qualify for free/or reduced lunch status. The purpose of the study was to explore if dual-language programs are effective for non-EL students that qualify for free/or…

A school in Virginia serves students with significant cognitive disabilities (SWSCDs) whose full scale IQ scores are 40 and below. The problem is the SWSCDs were administered the Virginia Alternate Assessment Program (VAAP) and did not perform well from 2017 to 2019. As a result, the school did not receive state accreditation. The purpose of this…

Background: Researchers are often interested in testing the effectiveness of an intervention on multiple outcomes, for multiple subgroups, at multiple points in time, or across multiple treatment groups. The resulting multiplicity of statistical hypothesis tests can lead to spurious findings of effects. Multiple testing procedures (MTPs)…

Education researchers frequently have to choose between statistical models for their data, and in many cases the candidate models or parameters can be listed in a sequence, m=1,...,M, from less preferable choices to more. For instance, in choosing a bandwidth for regression discontinuity designs, researchers would favor the largest possible…

Data from international large-scale assessments (ILSAs) of schooled populations indicate that boys have considerably poorer literacy skills than girls. New evidence from a household-based ILSA--Organisation for Economic Cooperation and Development Survey of Adult Skills (PIAAC)--indicates that the gender gap in literacy is negligible, even though…

We extended research on scaffolds for formulating scientific hypotheses, namely the Hypothesis Scratchpad (HS), in the domain of relative density. The sample comprised of secondary school students who used three different configurations of the HS: Fully structured, containing all words needed to formulate a hypothesis in the domain of the study;…

Although fairness in assessment practices (APs) in traditional classes has gained noticeable attention in recent years, it has remained unexplored in online education (OE). Thus, this study explores Iranian university English teachers' perceptions of fair APs in OE. For this purpose, 21 university English teachers from Lorestan University and…

As online courses become increasingly common at the college level, an ongoing concern is how to ensure academic integrity in the online environment. One area that has received particular attention is that of preventing cheating during unproctored online exams. In this study, we examine students' behavior during unproctored exams taken in an online…

Bribery is a complex and critical issue in higher education (HE), causing severe economic and societal harm. Traditionally, most scholarship on HE corruption has focused on institutional factors in developing countries and insights into the psychological and motivational factors that drive HE bribery on the micro-level mechanisms are virtually…

Many studies have shown that using a computer-aided detection (CAD) system does not significantly improve diagnostic accuracy in radiology, possibly because radiologists fail to interpret the CAD results properly. We tested this possibility using screening mammography as an illustrative example. We carried out two experiments, one using 28…

The emergent COVID-19 pandemic in Wuhan, China, at the end of 2019 has affected the whole world in a short time. Therefore, schools have been closed worldwide, and online learning opportunities have been exploited. Although lessons are taught online, problems have been experienced about measuring and evaluating lessons. This quasi-experimental…

When scaling psychological tests with methods of item response theory it is necessary to investigate to what extent the responses correspond to the model predictions. In addition to the statistical evaluation of item misfit, the question arises as to its practical significance. Although item removal is undesirable for several reasons, its…

Negated sentences are known to be more cognitively taxing than positive ones (i.e., "polarity effect"). We present evidence that two factors contribute to the polarity effect in verification tasks: processing the sentence and verifying its truth value. To quantify the relative contribution of each, we used a delayed verification task.…
