The War on Diabetes campaign was launched in 2016, encouraging Singapore residents to engage in regular exercise, adopt healthy dietary habits and screen for early detection of diabetes. This study aims to examine campaign awareness and its associations with sedentary behaviour, dietary habits and identifying diabetes. Data were obtained from the…

Background: Learning analytics (LA) research often aggregates learning process data to extract measurements indicating constructs of interest. However, the warranty that such aggregation will produce reliable measurements has not been explicitly examined. The reliability evidence of aggregate measurements has rarely been reported, leaving an…

Purpose: The word learning of preschool-age children with developmental language disorder (DLD) is improved when spaced retrieval practice is incorporated into the learning sessions. In this preregistered study, we compared two types of spacing--an expanding retrieval practice schedule and an equally spaced schedule--to determine if one of these…

In the existing multidimensional extensions of the log-normal response time (LNRT) model, the log response times are decomposed into a linear combination of several latent traits. These models are fully compensatory as low levels on traits can be counterbalanced by high levels on other traits. We propose an alternative multidimensional extension…

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 present study aimed to explore the association between creativity, intelligence, and personality. The study recruited sixty healthy volunteers in the age range of 20-40 years from Bengaluru city (formerly Bangalore), South India, and administered tests for fluid intelligence (Raven's Standard Progressive Matrices), personality (Big Five…

In design-oriented biomedical engineering courses, some instructors teach need-driven methods for health technology innovation that use a "need statement" to reflect a student team's hypothesis about the most fruitful direction for their project. While need statements are of the utmost importance to the projects, we were not aware of any…

Undergraduate research is a high-impact educational practice. However, few studies have analyzed the opportunities and barriers to entry into undergraduate research experiences. A survey for the measurement of undergraduate research science capital (URSC) was developed, rooted at the junction of science capital and social cognitive career theory.…

In this paper, we develop a mixed stochastic approximation expectation-maximization (MSAEM) algorithm coupled with a Gibbs sampler to compute the marginalized maximum a posteriori estimate (MMAPE) of a confirmatory multidimensional four-parameter normal ogive (M4PNO) model. The proposed MSAEM algorithm not only has the computational advantages of…

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…

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…

Screening for autism in childhood has been advocated as a part of standard care. Challenges exist with screening implementation and performance of screening tools in clinical practice. This study aimed to examine the validity and feasibility of using the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) for screening…

In this Age of the Anthropocene, the world of work is being radically disrupted by mass precarity, rising wage and income inequality, habitat destruction, and the rise of artificial intelligence. Facing such insecurity, people, we show, are careering toward radical ways of making a living. They range from radical professionals to social media…

The positive impact of Math Learning Support Centers (MLSCs) on student performance is well-documented in existing literature. However, we argue in this study that many of these evaluations could be improved methodologically. Using a more rigorous approach, we investigated the effect of an MLSC on students' performance and affective variables in…
