In current teaching materials, when using Dedekind cuts to construct real numbers, the definition of a Dedekind cut is always involved in defining addition and multiplication. In this paper, as it is done in many current textbooks, Dedekind cuts are used to construct the set of real numbers. Then the order in it is defined, and the…

Classification measures and entropy variants can be used as indicators of model fit for logistic regression. These measures rely on a cut-point, "c," to determine predicted group membership. While recommendations exist for determining the location of the cut-point, these methods are primarily anecdotal. The current study used Monte Carlo…

Various studies have indicated that incorporating origami activities into a geometry lesson can promote elementary and middle school students' mathematical reasoning, enhance their ability to use precise mathematical terminologies, and increase their communication skills. The authors wondered if origami activities have a place in high school…

Inspired by complex system theory, this study adopts a multilevel piecewise regression model to examine the relationship between homework time and the development of students in different grades using a large-scale testing database in China. The results indicate that the relationship between homework time and students' performance is positive when…

Identification of cardiometabolic risk (CMR) in U.S. younger population by assessing muscular strength via handgrip (HG) dynamometry may aid in prevention efforts. Currently, no nationally representative HG cut-points are available for identifying increased CMR in U.S. adolescents or young adults. In this study, we propose normalized grip strength…

America's colleges and universities are at a crossroads. The number of schools closing their doors continues to grow driven by the declining number of students pursuing a bachelor's. This situation is expected to worsen because of a number of factors: (1) Starting in 2025 the U.S. will face the so-called "enrollment cliff," in which the…

Commonly used cut-points may misclassify physical activity (PA) in people with cystic fibrosis (CF). The aim of this study was to develop and cross-validate condition-specific cut-points in children and adolescents with CF. Thirty-five children and adolescents with CF (15 girls; 11.6 ± 2.8 years) and 28 controls (16 girls; 12.2 ± 2.7 years), had…

Effective teaching requires enjoyable classroom tasks aimed at promoting students' learning of mathematics meaningfully, and previous research has demonstrated that the use of origami activities in mathematics classrooms can help achieve that goal. In this article, the authors describe their "LOVE MATH" one-straight-cut letter origami…

This brief is part of Education Law Center's "Tracking State Aid Cuts in the Pandemic" series. In June 2020, amid the economic crisis resulting from the COVID-19 pandemic, the Georgia Legislature enacted a 10% cut in state aid for K-12 public education totaling $950 million. The cut applied equally to all school districts, without regard…

Given the recent push for universal screening, it is important to take into account how well a screener identifies children at risk for reading problems as well as how screener and sample information contribute to this classification. Picking the best cut-point for a particular sample and screening goal can be challenging given that test manuals…

This study aims to demonstrate the optimal way to determine the cut-off score to be used to interpret the total scores obtained from an achievement test or scale using the Artificial Neural Networks method. To this end, the multiple-choice item responses in the Booklet-11 Mathematics subtest at the 8th grade level in the TIMSS 2015 Turkey sample…

During the Great Recession, which spanned 2008 and 2009, budget crises caused states to cut back on public education spending and schools responded by reducing spending on personnel, curriculum, and extra-curricular activities. This research article uses a unique survey conducted during the recession to analyse public attitudes towards different…

This article compares cut scores from two variations of the Hofstee and Beuk methods, which determine cut scores by resolving inconsistencies in panelists' judgments about cut scores and pass rates, with the Angoff method. The first variation uses responses to the Hofstee and Beuk percentage correct and pass rate questions to calculate cut scores.…

Autism spectrum disorder (ASD) and ASD symptoms are overrepresented among gender-diverse youth across studies. Gender-diverse and ASD youth are at risk for anxiety, but anxiety is unclear among gender-diverse youth with ASD. The Social Communication Questionnaire (SCQ) is a commonly used ASD screener, including in multidisciplinary…
