Walsh, Bridget; Bostian, Anna; Tichenor, Seth E.; Brown, Barbara; Weber, Christine – Journal of Speech, Language, and Hearing Research, 2020
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…

Chang, Annalisa C.; Ammerman, Angela – String Research Journal, 2020
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…

Eichelberger, Brenda; Gerbing, David; Gilpatrick, Thomas – College Student Journal, 2020
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…

Hemer, David – Australian Mathematics Education Journal, 2020
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…

Clauser, Brian E.; Kane, Michael; Clauser, Jerome C. – Journal of Educational Measurement, 2020
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…

Yusuf, Mardiana; Rahim, Suzieleez Syrene Abdul; Eu, Leong Kwan – Malaysian Online Journal of Educational Sciences, 2020
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…

Arria, Amelia M.; Allen, Hannah K.; Caldeira, Kimberly M.; Vincent, Kathryn B.; O'Grady, Kevin E. – Journal of American College Health, 2020
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…

Vo, Tat-Thang; Porcher, Raphael; Chaimani, Anna; Vansteelandt, Stijn – Research Synthesis Methods, 2019
Case-mix heterogeneity across studies complicates meta-analyses. As a result of this, treatments that are equally effective on patient subgroups may appear to have different effectiveness on patient populations with different case mix. It is therefore important that meta-analyses be explicit for what patient population they describe the treatment…

Porter, C. D.; Heckler, A.F. – Physical Review Physics Education Research, 2019
Quantum mechanics is a notoriously counterintuitive subject within physics and has been the subject of a number of studies at the undergraduate level, and a few pioneering studies at the graduate level. The sketching of wave functions in a confining well is in one sense one of the most basic activities in quantum mechanics. But in another sense,…

Liebscher, Eckhard; Michael, Ben – International Electronic Journal of Mathematics Education, 2019
In the paper a software solution is presented for the generation of instances of exercises. The focus is on education in mathematics but the approach can be adopted in other fields such as computer science and natural science. The present solution uses the R environment for the generation process and LaTeX for the content presentation. In the…

Rivadulla, Francisco – Journal of Chemical Education, 2019
The Maxwell distribution of speeds, f(v), is the starting point for the calculation of the transport coefficients in kinetic-molecular theory. Most physical chemistry textbooks follow a path to derive f(v) similar to that used by Maxwell, which makes it difficult for students to understand its relationship with the equilibrium state of the system,…

Lanham, Susan W. – American Journal of Business Education, 2019
Most literature related to Benford's Law discusses what the law can be used for and how it works but fails to address effective methods and procedures for teaching the law to students. This article examines existing information resources to determine the most effective methods and procedures used to explain this Law to those who have no experience…

Hoon, Teoh Sian; Singh, Parmjit – Asian Journal of University Education, 2019
There are challenges in teaching research methodology as highlighted by many researchers. Among the challenges are strategies for putting material in context. For achieving this purpose, students' engagement in the learning process needs to be re-looked. This paper shares on a practice engaging students in a research methodology class. The…

Gorard, Stephen – International Journal of Social Research Methodology, 2019
This paper compares the use of confidence intervals (CIs) and a sensitivity analysis called the number needed to disturb (NNTD), in the analysis of research findings expressed as 'effect' sizes. Using 1,000 simulations of randomised trials with up to 1,000 cases in each, the paper shows that both approaches are very similar in outcomes, and each…

Leite, Walter L.; Aydin, Burak; Gurel, Sungur – Journal of Experimental Education, 2019
This Monte Carlo simulation study compares methods to estimate the effects of programs with multiple versions when assignment of individuals to program version is not random. These methods use generalized propensity scores, which are predicted probabilities of receiving a particular level of the treatment conditional on covariates, to remove…
