Background Little is known about the health needs of people with intellectual disabilities who access out-of-hours primary care services, raising concerns about accessibility and quality of care for this group. This study aims to identify commonly presented health problems of people with intellectual disabilities in this specific setting compared…

The statistical concept of sampling is often given little direct attention, typically reduced to the mantra "take a random sample". This low resource and adaptable activity demonstrates sampling and explores issues that arise due to biased sampling.

Nationwide, the percentage of four-year-olds enrolled in state-supported preschool programs has more than doubled since the early 2000s as states dramatically increased their investments in early childhood education. Florida's Voluntary Pre-kindergarten Program (VPK), which began in 2005, has been a national leader with respect to preschool…

The present research paper introduces a translation evaluation method called Calibrated Parsing Items Evaluation (CPIE hereafter). This evaluation method maximizes translators' performance through identifying the parsing items with an optimal p-docimology and d-index (item discrimination). This method checks all the possible parses (annotations)…

This study aims to analyse the reasoning that children and adults with the same school level use to assess and justify the fairness of games, considering aspects of probability such as randomness, sample space, and comparison of probabilities. Data collection included a Piagetian clinical interview based on games of chance. The results showed that…

The purpose of this study was to understand the contextual, school-level factors associated with the availability of arts education courses in the high schools of the United States. In the study, course offerings for a nationally representative sample of N = 940 high schools that were part of the National Center for Education Statistics High…

Objective: This study examines how accurately a small set of short-term academic indicators can approximate long-term outcomes of community college students so that decision-makers can take informed actions based on those indicators to evaluate the current progress of large-scale reform efforts on long-term outcomes, which in practice will not be…

The structural conditions by which Black and Latinx students experience education have created an opportunity gap in the access to equitable educational resources, likely leading to reduced educational outcomes. Attempts to understand how educational resources impact educational outcomes for Black and Latinx students are usually limited because of…

Some IRT models can be equivalently modeled in alternative frameworks such as logistic regression. Logistic regression can also model time-to-event data, which concerns the probability of an event occurring over time. Using the relation between time-to-event models and logistic regression and the relation between logistic regression and IRT, this…

There is a wealth of evidence that people's reasoning is influenced by explanatory considerations. Little is known, however, about the exact form this influence takes, for instance about whether the influence is unsystematic or because of people's following some rule. Three experiments investigate the descriptive adequacy of a precise proposal to…

Increasing the size and diversity of the scientific and technological workforce is a national priority. Investments in policy and programmatic efforts toward increasing the representation of women in science and engineering fields have resulted in significant advances; however, a gender gap remains among PhDs and faculty in these fields. This…

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the…

W scores are used in a number of commercially available tests. Due to their complex nature, it can be hard for applied researchers and practitioners to understand them or even acquire information about them beyond what is provided in technical manuals. In this article, we provide information regarding the background and derivation of W scores that…

This literature-based, classroom-tested novel innovation of educational song (with pedagogical scaffolding) may help engage students explore and address common resistant misconceptions in probability (e.g. all outcomes are equally likely) and in statistics (e.g. correlation must imply either causation or coincidence).

In India, universities often study the broad characteristics of students who migrate to their state for educational purposes. This provides them with opportunities to collaborate with the state government in order to introduce education policies that can influence future students' migration decisions. While studies already exist that focus on the…
