The expansion and universalization of educational opportunities in many parts of the world raised expectations that education inequality could be alleviated. Contrary to expectations, however, empirical evidence on educational inequality has been revealed. This is because qualitative differentiation of education programs at a certain level of…

A number of studies report that frequency is a poor predictor of acceptability, in particular at the lower end of the frequency spectrum. Because acceptability judgments provide a substantial part of the empirical foundation of dominant linguistic traditions, understanding how acceptability relates to frequency, one of the most robust predictors…

Purpose: The purpose of this study is to document disfluency behaviors expressed by 4- and 5-year-old children who stutter and to identify whether stuttering characteristics at this age are predictive of later stuttering recovery or persistence. Method: We analyzed spontaneous speech samples from 47 children diagnosed with developmental stuttering…

The rise in demand for string teachers is a sign of support for string programs across the United States. Despite an increase in string teacher positions, there is growing concern regarding the lack of qualified string music education graduates to fill the vacancies, sometimes leading administrators to close programs. This study investigated the…

This study analyzes the relationship of completion of a college level personal finance course to undergraduate retention and graduation rates. Through the utilization of comparative data, results demonstrated that students who completed the personal finance course had a significantly higher probability of year to year retention and successful…

This paper describes an investigation looking at the underlying mathematics of poker machines. The aim of the investigation is for students to get an appreciation of how poker machines are designed to ensure that in the long-term players will inevitably lose when playing. The first part of this paper describes how students can model a simple poker…

An Angoff standard setting study generally yields judgments on a number of items by a number of judges (who may or may not be nested in panels). Variability associated with judges (and possibly panels) contributes error to the resulting cut score. The variability associated with items plays a more complicated role. To the extent that the mean item…

Various solving strategies in probability of events could complicate the students in choosing the best strategy in problem solutions. This research was carried out to identify the favourite solving strategies used by college students to solve probability and event problems. As a preliminary of a case study, only three students were selected as…

Objective: This study examines the prospective relationship between substance use during college and two outcomes: having definite plans to attend graduate school; and, among individuals with plans, enrolling in graduate school upon college graduation. Participants: n = 980 were originally enrolled as first-time, first-year college students in an…

University students and faculty members need an effective strategy to evaluate and reduce the probability that an individual will become infected with COVID-19 as a result of classroom interactions. Models are developed here that consider the probability an individual will become infected as a function of: prevalence of the disease in the…

This article considers how a handicapping system should be devised for squash. It looks at the American scoring system, and whether it is possible to have a fair system of handicapping. We consider "fair" from a perspective of expected number of rallies won and probability of winning.

This study explores how student employment affects college persistence and how these effects differ by individual likelihood of participating in student employment. I analyze data from the National Longitudinal Survey of Youth 1997 using propensity score matching and stratification-multilevel analysis. This study finds that engaging in intense…

This paper explores the use of irony in narratives that focus on the problem of knowing what we do not know. Sometimes issues arise on a grand scale, as in the literature of Socrates, Pascal, and Descartes, where the question really is whether we can know anything at all or whether all that we can know is that there is nothing worth knowing that…

A key part of determining cut-scores when performing Angoff standard setting is utilizing equating methods to place standard-setting ratings onto the scale used to report scores to examinees. This article describes three equating methods that can be employed to place Angoff ratings onto the scale used to report scores to examinees when applying…

This research study provides an examination of the relatively new fields of Data Analytics and Data Science. We compare word rates in Data Analytics and Data Science documents to determine which concepts are mentioned most often. The most frequent concept in both fields is "data." The word rate for "data" is more than twice the…
