The purpose of the current study was to determine the probability that a student with a disability not being served by Individuals with Disabilities Education Act (IDEA) would be expelled. Expulsion data were obtained from the Civil Rights Data Collection produced by the U.S. Office of Civil Rights. The latest data from all 50 states and the…

Attention-deficit/hyperactivity disorder (ADHD) overdiagnosis and overtreatment unnecessarily exposes children to potential harm and contributes to provider and community skepticism toward those with moderate or severe symptoms and significant impairments, resulting in less supportive care. Yet, which sociodemographic groups of children are…

We examined the effect of three components of self-determination--autonomy, empowerment, and self-realization--on the postsecondary enrollment of English learners with disabilities, using quasi-experimental propensity score modeling and data from the U.S. National Longitudinal Transition Study-2. Results support the hypothesis that…

Stochastic independence is not an easy notion. Because it is part of the probability structure, it can have some surprising non-properties, which is beneficial for teachers and students to see illustrated. Neither is the relationship to causal independence an easy one.

Administrative problems such as computer malfunction and power outage occasionally lead to missing item scores and hence to incomplete data on mastery tests such as the AP and U.S. Medical Licensing examinations. Investigators are often interested in estimating the probabilities of passing of the examinees with incomplete data on mastery tests.…

International virtual exchange is gaining popularity as an innovative approach to providing international experiences to students, particularly considering the COVID-19 pandemic. However, little research has been conducted on this unique teaching approach or how it fits into university comprehensive internationalization plans. In this paper, we…

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…

Purpose: The paper innovates on the existing literature by assessing the gender gap in Science, Technology, Engineering and Maths (STEM) tertiary education enrolment and career choice in a small country setting and by extending on Master and Meltzoff (2016) theoretical framework to provide a holistic explanation of the gender disparity through a…

Large-scale education data are collected via complex sampling designs that incorporate clustering and unequal probability of selection. Multilevel models are often utilized to account for clustering effects. The probability weighted approach (PWA) has been frequently used to deal with the unequal probability of selection. In this study, we examine…

We use a database of over 15,000 teacher candidates from 15 teacher education programs in Washington state to investigate the connections between specific teacher preparation experiences and the likelihood that these candidates enter and stay in the state's public teaching workforce. As has been found in prior research, candidates with…

Many developing countries have experienced increasing spatial inequality, but little is known about the effect of community disadvantages on educational attainment in these societies. Using data from the China Family Panel Studies (2010-2016), I examine the effect of community socioeconomic status (SES) on the transition into high school in urban…

Solving real-life problems through mathematical modeling is one of the aims of modern mathematics curricula. For this reason, prospective mathematics teachers need to acquire modeling skills and use these skills in learning environments in terms of creating rich learning environments. With this study, it is aimed to examine the reflections of…

Probabilistic thinking is a structure of thinking characterized by scenarios that allow one to explore reality. Therefore, the characteristic of probabilistic thinking is problem-oriented that will occur in a future full of uncertainty. Nevertheless, few studies examine the students' probabilistic thinking level based on the Stress Tolerance…

Merit aid is an increasingly important component of college scholarships, but policymakers are concerned that merit aid is often given to students who would enroll anyway. As a baseline we use a regression discontinuity (RD) framework to test an institution-level merit aid program at a public research university and find that the merit aid program…

The transition from the probability mass function for discrete random variables to the probability density function for continuous random variables is not straightforward, especially to students from the health and social sciences. An R Shiny application was created to assist the learning process of probability density function.
