Purpose: Although the science, technology, engineering, and math (STEM) pipeline has been the most common policy framework to understand why ethnoracial disparities are some of the most glaring, few studies have empirically assessed whether the relationship between early academic preparation, such as for standardized tests, grades, and coursework,…

Sleep problems are prevalent among individuals with Rett syndrome. We aimed to investigate sleep problems in individuals with Rett syndrome and their caregivers. A total of 29 participants diagnosed with Rett syndrome and their respective 29 caregivers were included. The Children Sleep Habits Questionnaire (CSHQ), the Pittsburgh Sleep Quality…

Academia and education advocates have reported a concern about the elimination of art and music education classes from high school curriculums in the United States. Studies using mean SAT test scores from 1984 and 1994 versions of the SAT test indicated participants who had art and music education classes had higher verbal and mathematical SAT…

College student employment has become an important aspect of life for many students pursuing higher education. Student employment programs provide students with the opportunity to earn income while learning skills that contribute to their personal and professional development. The impact of student employment on student development and the overall…

In many large-scale testing programs, examinees are frequently categorized into different performance levels. These classifications are then used to make high-stakes decisions about examinees in contexts such as in licensure, certification, and educational assessments. Numerous approaches to estimating the consistency and accuracy of this…

This dissertation examined classification outcome differences among four popular individual supervised machine learning (ISML) models (logistic regression, decision tree, support vector machine, and multilayer perceptron) when predicting minor class membership within imbalanced datasets. The study context and the theoretical population sampled…

The process of generating challenging and appropriate distractors for multiple-choice questions is a complex and time-consuming task. Existing methods for an automated generation have limitations in proposing challenging distractors, or they fail to effectively filter out incorrect choices that closely resemble the correct answer, share synonymous…

Project Lead the Way (PLTW) is an applied STEM program first introduced nearly three decades ago to enhance the STEM content of Career Technical Education (CTE). Currently, more than 12,000 US high schools offer the program. Using data from three cohorts of public high school freshmen in Missouri, we investigate the impact of PLTW program offer…

This study aimed to provide meta-analytic reliability information of the Columbia-Suicide Severity Rating Scale (C-SSRS). We implemented systematic search procedures to 35 eligible studies (N = 23,247; Mage = 26.74 years) that reported reliability estimates. The synthesized average values of Cronbach's alpha were 0.88 (95% CI [0.85, 0.92]) for the…

In a 1984 essay, Benjamin Bloom, an educational psychologist at the University of Chicago, asserted that tutoring offered "the best learning conditions we can devise" and that tutors could raise student achievement by two full standard deviations--or, in statistical parlance, two "sigmas." The influence of Bloom's two-sigma…

The attention time of students studying in MOOC (Massive Open Online Courses) classroom was analyzed to optimize and further improve their performance. On this basis, a student class model based on convolutional neural networks (CNN) feature extraction was proposed. Through Pr (Adobe Premiere) technology, students' class videos were processed by…

Scoring in creativity research has been a central problem since creativity became an important issue in psychology and education in the 1950s. The current study examined the psychometric properties of 27 creativity indices derived from summed and averaged scores using 15 scoring methods. Participants included 2802 middle-school students. Data…

The purpose of this study was to determine if there has been a change to the scores on the Texas State Peace Officer Licensing Examination over a given time, and if been a so, identify subjects where scores improved or declined. By recognizing stagnation or declination in test scores, interventions can be designed to enhance the adult learning…

The Accreditation Board for Engineering and Technology (ABET) which accredits higher education programs globally, has placed the ability for students to recognize professional and ethical responsibilities among their seven stated student outcomes that undergraduate engineering programs must ensure their students achieve to maintain their…

One of the greatest challenges for schools is to identify effective and ineffective teachers in a classroom. Teacher evaluation is an expensive process in both time and resources. It is important that evaluations provide data to improve teaching and learning. Therefore, each evaluation needs to communicate opportunities for growth. This…
