The rise of online proctoring potentially provides more opportunities for item harvesting and consequent brain dumping and shared "study guides" based on stolen content. This has increased the need for rapid approaches for evaluating and acting on suspicious test responses in every delivery modality. Both hiring proxy test takers and…

We present the R package and web app "statcheck" to automatically detect statistical reporting inconsistencies in primary studies and meta-analyses. Previous research has shown a high prevalence of reported p-values that are inconsistent--meaning a re-calculated p-value, based on the reported test statistic and degrees of freedom, does…

A potential negative consequence of high-stakes testing is inappropriate test behaviour involving individuals and/or institutions. Inappropriate test behaviour and test collusion can result in aberrant response patterns and anomalous test scores and invalidate the intended interpretation and use of test results. A variety of statistical techniques…

Simulation studies use computer-generated data to examine questions of interest that have traditionally been used to study properties of statistics and estimating algorithms. With the recent advent of powerful processing capabilities in affordable computers along with readily usable software, it is now feasible to use a simulation study to aid in…

The Missouri Department of Elementary and Secondary Education (DESE), in response to recommendations in the Annual Report of the Advisory Council on the Education of Gifted and Talented Students (2015), has produced this document to provide guidance for school districts to more equitably identify and meet the needs of traditionally…

The potential of social media to give insight into the dynamic evolution of public conversations, and into their reactive and constitutive role in political activities, has to date been underdeveloped. While topic modeling can give static insight into the structure of a conversation, and keyword volume tracking can show how engagement with a…

More than half of North Carolina's grade 3 students struggle with reading. The percentage of students scoring below proficient in reading at the end of grade 3 was 55 percent in 2017/18. That percentage has remained largely unchanged, at above 50 percent, since 2013/14, when North Carolina passed its K-3 Read to Achieve literacy act. Read to…

Many states are attempting to identify schools that perform better than schools with similar populations. Such "beating-the-odds" schools offer opportunities to identify promising practices that can be implemented by other schools serving similar populations. This study uses data from the Michigan Department of Education to demonstrate…

This article defends a view of personhood based on regarding oneself as "one among others." This relational conception stands in contrast to Western and Eastern stereotypes of the free-standing individual who sees himself in competition with other individuals, and the collectivist individual who sees himself as part of a larger…

The purpose of this paper is to describe effect coding as an alternative quantitative practice for analyzing and interpreting categorical, multi-raced independent variables in higher education research. Not only may effect coding enable researchers to get closer to respondents' original intentions, it allows for more accurate analyses of all race…

This chapter offers both challenges and new directions in conducting quantitative assessments and research with queer-spectrum and trans-spectrum college student populations. Both the challenges and future directions are grounded in the literature and the experiences of the authors.

Many small-molecule antioxidants found in whole fruits and vegetables are analyzed and identified in this laboratory module for upper-division biochemistry courses. During this experiment, students develop their knowledge of the bioactivity of fruit and vegetable products while learning techniques to identify vitamins and nutritionally derived…

The purposes of this paper are to (a) propose an operational standard for defining a "practice," (b) encourage development of professional standards for visual and statistical analysis of single-case research, and (c) propose a standard for using single-case research results to identify practices that are "evidence-based." These topics are not new…

Recently there has been a renewed interest in formative measurement and its role in properly specified models. Formative measurement models are difficult to identify, and hence to estimate and test. Existing solutions to the identification problem are shown to not adequately represent the formative constructs of interest. We propose a new two-step…

The G-DINA ("generalized deterministic inputs, noisy and gate") model is a generalization of the DINA model with more relaxed assumptions. In its saturated form, the G-DINA model is equivalent to other general models for cognitive diagnosis based on alternative link functions. When appropriate constraints are applied, several commonly used…
