Utilizing a longitudinal item response model, this study investigated the effect of item parameter drift (IPD) on item parameters and person scores via a Monte Carlo study. Item parameter recovery was investigated for various IPD patterns in terms of bias and root mean-square error (RMSE), and percentage of time the 95% confidence interval covered…

This qualitative study used 97 participants to explore differences in the expression of state, trait, social interest, and taking charge between students with military experience and students without such experience. The results indicated a significant correlation of the scores on the Belonging/Social Interest Subscale (BSI) with trait anxiety, as…

The research study was conducted with the primary purpose to evaluate the overall delivery of information conveyed to minority students who attended visitation programs at The Ohio State University and Purdue University. The sample population used in this study was 120 students who attend visitation programs at the two listed institutions. Survey…

Two experiments are reported in which people resolve references to sets of entities (e.g., lies) that have previously been introduced either explicitly into a text ("the lies") or implicitly via a cognate verb (a form of the verb "to lie"). Previous work has show that pronominal references to such entities were judged as…

Global carbon cycling describes the movement of carbon through atmosphere, biosphere, geosphere, and hydrosphere; it lies at the heart of climate change and sustainability. To understand the global carbon cycle, students will require "interdisciplinary knowledge." While standards documents in science education have long promoted…

The present study aimed to identify the reality of E-Learning systems and tools use (Blackboard) by faculty members and students in teaching and learning courses at the college of education at Najran University. To achieve this aim, two questionnaires for both faculty members and students were developed. A sample of (60) faculty members and (120)…

Background: Reliability of nonprobability online volunteer panels for epidemiological purposes has rarely been studied. Objectives: To assess the quality of a questionnaire on sexual and reproductive health (SRH) administered in a nonprobability Web panel and in a random telephone survey (n = 8,992; n = 8,437, age 16-49 years). Especially, we were…

The study explored in-service teachers' efficacy beliefs in pupil engagement. The sample size was 299 kindergarten teachers selected from both public and private kindergarten schools in the Kumasi metropolis of Ghana. The study adopted and used pupil engagement subscale of the Ohio State Teacher Efficacy Scale (OSTES) developed by Tschannen-Moran…

To examine what kinds of parent-child interactions are elicited by different literacy-related activities, an exploratory study was conducted with 19 mother-child dyads. Although prompting boards are widely incorporated in pre- and primary school curricula, and in various family literacy programmes, scientific knowledge supporting their use is…

Autism spectrum disorder is the fastest growing developmental disability in the United States. As such, there is an unprecedented need for research examining factors contributing to the health disparities in this population. This research suggests a relationship between the levels of physical activity and health outcomes. In fact, excessive…

It is common practice for assessment programs to organize qualifying sessions during which the raters (often known as "markers" or "judges") demonstrate their consistency before operational rating commences. Because of the high-stakes nature of many rating activities, the research community tends to continuously explore new…

Stan is a new Bayesian statistical software program that implements the powerful and efficient Hamiltonian Monte Carlo (HMC) algorithm. To date there is not a source that systematically provides Stan code for various item response theory (IRT) models. This article provides Stan code for three representative IRT models, including the…

Every year, over 20,000 Hispanics enlist in the U.S. military. Their military experiences influence their long-term educational outcomes. This exploratory study estimates the effect of military service on education level completed by men up to 15 years after initial enlistment. Findings suggest that technical military jobs, more than nontechnical…

The aim of the study is to investigate the effect of 8-week Nordic Hamstring (NH) exercise on hamstring/quadriceps ratio (H/Q) and hamstring muscle strength. 22 amateur soccer players participated in the study. Soccer players were divided into two groups: the control group (CG) (n = 11) who only practiced soccer training and the Nordic Hamstring…

Imitation problems are commonly reported in children with an autism spectrum disorder. However, it has not yet been determined whether imitation problems persist into young adulthood. In this study, we investigated imitation skills of 20 intellectually able young adults with autism spectrum disorder relative to 19 age-matched neurotypical adults.…
