Objective: Low-income parents experience higher rates of depression due to their exposure to poverty-related stress. This study tested the Adaptation to Poverty Related Stress (APRS) model's proposed relationships between poverty-related stress, depression, and the protective roles of ethnic identity affirmation (EI), social support, and…

Classroom teachers in the US are absent on average approximately six percent of a school year. Despite the prevalence of teacher absences, surprisingly little research has assessed the key source of replacement instruction: substitute teachers. Using detailed administrative and survey data from a large urban school district, we document the…

The current study has gathered responses from teachers employed by a South TexasCharter school network regarding teacher retention factors. The United States Department of Education published an extensive list of teacher shortage areas every year. Schools struggle with the retention and attrition of qualified teachers as student enrollment…

Survival is difficult to estimate when observation periods of individuals differ in length. Students imagine sailing the Titanic and then recording whether they "live" or "die." A clever algorithm is performed which results in the Kaplan-Meier estimate of survival.

Learning probabilistic classification and prediction models that generate accurate probabilities is essential in many prediction and decision-making tasks in machine learning and data mining. One way to achieve this goal is to post-process the output of classification models to obtain more accurate probabilities. These post-processing methods are…

Differential reinforcement procedures may promote unprompted correct responding, resulting in a quicker transfer of stimulus control than nondifferential reinforcement. Recent studies that have compared reinforcement arrangements have found that the most effective arrangement may differ across participants. The current study conducted an…

Taking more than one measurement of the same variable also hosts the possibility of contamination from error sources, both singly and in combination as a result of interactions. Therefore, although the internal consistency of scores received from measurement tools is examined by itself, it is necessary to ensure interrater or intra-rater agreement…

The primary purpose of the research study was to examine the Army's Transition Assistance program, achieve a comprehensive understanding of Army culture from the perspective of senior enlisted members and their subsequent contingent valuations regarding mentoring colleagues in transition from active duty commitment to the civilian sector. Study…

Purpose: To determine the differences between PT program NPTE 3-year ultimate pass rates (3YUPR) based on program length and faculty scholarship. To explore relationships between 3YUPR and quality faculty behaviors. Subjects: A total of 112 CAPTE accredited PT educational programs in the United States and Puerto Rico during 2013. Method: A…

Source-based writing is a complex and frequently occurring task type in postsecondary education. While a large body of research now exists investigating source-based student writing, few studies have used corpus-based methods to investigate L1 student performance on source-based writing tasks and to connect this performance to the holistic quality…

This study explores Korean-American parents' perceptions on successful transition to kindergarten (TTK) for their child on the autism spectrum. It further examines challenges experienced during this process, and possible predictors for their challenges. Findings from an online survey (N = 212) indicate that participants consider their child's…

Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

In this study, the effects of some student (e.g., gender, bullying, etc.) and school variables (e.g., emphasis on academic achievement, clarity of teaching, etc.) on the TIMSS 2015 science and mathematics achievement of eighth grade students in Türkiye were examined by controlling for the socioeconomic status of the students at the student and…

Skills in science, technology, engineering and mathematics (STEM) are promoted by the Australian government as pivotal for Australia's economic prosperity. Research on equity groups suggests that group membership is associated with several factors linked to 'leakage' from the STEM pipeline of school, university and transition to work. In this…

This study investigated U.S. undergraduates' perceptions of non-native speakers' (NNS) speech which had received 100% proficiency scores on the TOEFL iBT test. Fifty-five U.S. undergraduates rated 20 speech samples for comprehensibility, accentedness, and acceptability. The speech samples were also analyzed for acoustic fluency. Descriptively,…
