My study seeks to explore the extent that select secondary and postsecondary indicators predict STEM student enrollment and persistence particularly for Hispanic students. Identifying postsecondary STEM success and college readiness indicators with special focus on malleable indicators that can assist educators, administrators, and policymakers in…

Nonconsensual sexual activity remains a prominent and troubling aspect of undergraduate student life at U.S. colleges and universities. Past research revealed that 23.6% of female undergraduate students, and 5.8% of male undergrads, had experienced nonconsensual sexual contact. Given the scope of the problem, identifying groups of students…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

We analyzed the effects of a game-based, supplemental fraction curriculum on fourth and fifth grade students' fraction knowledge, engagement, and STEM interest. Students with and without disabilities with intersecting identities (e.g., race, disability status, gender) comprised the sample. Results indicate significant differences in fraction…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

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…

Modern educational technology has the potential to support students to use their study time more effectively. Learning analytics can indicate relevant individual differences between learners, which adaptive learning systems can use to tailor the learning experience to individual learners. For fact learning, cognitive models of human memory are…

In this study, we develop and implement a text messaging re-enrollment campaign to encourage former community college students to return to college. Former students are randomly assigned to one of two treatment groups that either receives information to simplify the re-enrollment process or receives both information and a one-course tuition…

Background: Food insecurity (FI) is a significant predictor of feelings of isolation in children, as well as suicide ideation and depression. Using a census of public middle school-aged children, we seek to determine whether FI is associated with suicide ideation and feelings of hopelessness and how individual and school community factors can…

Industry-school partnerships offer authentic learning opportunities and can support the development of students' interest in a STEM career. The expectancy-value model of achievement-related choice can help to explain how several factors influence career choice. Interest-enjoyment values and attainment values are most important in students'…
