Sales management students carry certain misconceptions about sales jobs, which often create confusion in their minds about the nature of the sales job- should they be customer-oriented or sales-oriented? To excel in the initial years of their careers as effective salespersons, students might emphasize sales-orientation or target achievement over…

Sub-Saharan Africa exhibits higher fertility and lower education than other world regions. Economic and demographic theory posit that these phenomena are linked, with slow fertility decline connected to slow education growth among both adults and children. Using microdata from 33 African countries, this paper documents the co-evolution of adult…

A regression model of predictor trade-offs is described. Each regression parameter equals the expected change in Y obtained by trading 1 point from one predictor to a second predictor. The model applies to predictor variables that sum to a constant T for all observations; for example, proportions summing to T=1.0 or percentages summing to T=100…

Proficiency rates on Pennsylvania's statewide assessments in 2022 remain below pre-pandemic levels, especially in math, but there is evidence that student learning has begun to recover. Proficiency rates for grades 5-8 in 2022 improved in both English language arts (ELA) and math relative to rates predicted for 2021 from a Mathematica research…

The findings of this study suggest that while the FRR score provides a reasonable indication of financial fragility over a subsequent five-year period, the FRR score is little better than a coin flip in predicting whether a religiously affiliated higher education institution will be financially troubled enough to close within the subsequent five…

The dropout of students is one of the major obstacles that ruin the improvement of higher education quality. To facilitate the study of students' dropout in Moroccan universities, this paper aims to establish a clustering approach model based on machine learning algorithms to determine Moroccan universities categories. Our objective in this…

The fit of an item response model is typically conceptualized as whether a given model could have generated the data. We advocate for an alternative view of fit, "predictive fit", based on the model's ability to predict new data. We derive two predictive fit metrics for item response models that assess how well an estimated item response…

A simple inquiry-based activity called "Fruit Puzzle" was designed to investigate high school students' understanding of the relationship between the concepts of density and solution concentration at a submicroscopic level. The first activity allowed students to predict whether five types of fruit would sink or float in water and asked…

The purpose of the study was to investigate if commonly collected data correlates with student success at week eight of the first term for first time, full time, students. This is an ex-post facto study of student data. A Spearman's rho test was used to analyze the data for correlational analysis to determine if variables contained within…

Knowledge tracing (KT) is a method to evaluate a student's knowledge state (KS) based on their historical problem-solving records by predicting the next answer's binary correctness. Although widely applied to closed-ended questions, it lacks a detailed option tracing (OT) method for assessing multiple-choice questions (MCQs). This paper introduces…

The pursuit of a master's degree is a significant academic endeavor, one that is influenced by a complex interplay of factors extending beyond traditional academic performance. In this study, we estimate the determinants of timely master's degree completion (i.e., within 3 years) using modern machine learning models such as random forest, decision…

This study presents a novel approach to improving quality assurance in the Trends in International Mathematics and Science Study (TIMSS). It utilizes a combination of neural networks and regression analysis to validate country-level achievement scores. Concerns over the integrity of TIMSS test scores necessitate robust quality control methods. The…

Despite some gains, women continue to be underrepresented in many science, technology, engineering, and math (STEM) fields. Using a national longitudinal dataset of 690 participants born in 1991, we tested whether spatial skills, measured in middle childhood, would help explain this gender gap. We modeled the relation between 4th-grade spatial…

Prevalence of contract cheating and outsourcing through organised methods has received interest in research studies aiming to determine the most suitable strategies to reduce the problem. Few studies have presented an international approach or tested which variables could be correlated with contract cheating. As a result, strategies to reduce…

This article reports the findings of a study on cooperative factors that predict higher education students' satisfaction with using collaborative online tools. Although there is evidence of relationships between certain factors of teamwork and satisfaction in traditional groups that are guided by their teacher, little is known about what happens…
