This work reports the results of a research aimed to know the probabilistic reasoning of high-school students when they deal with the notion of random intervals. An activity was carried out involving students between ages 16 and 17 who built random intervals through physical and computational simulations. The research question guiding this work…

Digital educational technologies offer the potential to customize students' experiences and learn what works for which students, enhancing the technology as more students interact with it. We consider whether and when attempting to discover how to personalize has a cost, such as if the adaptation to personal information can delay the adoption of…

Sickle cell disease is a very common disease throughout the world. We used it to contextualize probability for upper elementary school students. Using Punnett squares, activities guide students' evaluation of inheritance using theoretical probability. Then, students perform trials using tools to compare theoretical and experimental probabilities.

Recent research suggests that dual enrollment programs are a useful recruiting tool for colleges and universities as many high school students remain at their dual enrollment institution after high school graduation. Students staying enrolled at their dual enrollment institution for college may be beneficial for institutions, but is it beneficial…

Objective: Dual enrollment has become a significant portion of community college enrollment throughout the country. Some scholars have argued that dual enrollment implementation can be used as a viable policy lever to achieve the certificate and associate degree obtainment outcomes identified in "Reclaiming the American Dream," a…

Research on teaching and learning quantum physics (QP) frequently explores students' conceptual difficulties to identify common patterns in their reasoning. The abstractness of QP is often found to be at the origin of students' conceptual difficulties. Due to this abstract nature students resort to common sense reasoning or classical thinking when…

We examined the effect of three components of self-determination--autonomy, empowerment, and self-realization--on the postsecondary enrollment of English learners with disabilities, using quasi-experimental propensity score modeling and data from the National Longitudinal Transition Study-2. Results support the hypothesis that self-determination…

Undergraduate students tend to struggle with probability in their introductory statistics course. Probability problem solving requires several steps. First, students must make sense of the probability scenario, then determine the appropriate probability rules, and finally, execute the procedures to solve the problem. With no previous exposure to…

A Machine Learning framework for predicting enrollment is proposed. The framework consists of Amazon Web Services SageMaker together with standard Python tools for data analytics, including Pandas, NumPy, MatPlotLib, and ScikitLearn. The tools are deployed with Jupyter Notebooks running on AWS SageMaker. Based on three years of enrollment history,…

The transition from vocational education and training to regular employment is an important step in the occupational biography of apprenticeship graduates. In the last decade, the retention rate of apprenticeship completers has remained stable at a high level, and graduates face good job opportunities in Germany. Despite these positive…

This study investigated the extent to which class-specific parameter estimates are biased by the within-class normality assumption in nonnormal growth mixture modeling (GMM). Monte Carlo simulations for nonnormal GMM were conducted to analyze and compare two strategies for obtaining unbiased parameter estimates: relaxing the within-class normality…

Interpreting phenomena under uncertainty stands as a substantial cognitive activity in our daily life. Furthermore, in probability education research, there is a need for developing a unified model that involves several probabilistic conceptions. From this aspect, a central inquiry has been raised through this study: how do preservice mathematics…

The article analyses the effect of gender in professors' career advancement using data on the entire population of professors in the Italian university system, data on the National Scientific Qualification (NSQ) accreditation scheme, and data on scientific productivity (SciVal) for bibliometric scientific sectors. As NSQ accreditation is a…

There is increasing attention on the retention of international students, with many stakeholders desiring to keep international students for long-term economic growth. This study examined the factors affecting international students choosing to stay in Finland 5 years after initial enrollment, with particular focus on the role graduation plays in…

We estimate the relationship between exclusionary discipline given in eighth-grade and the probability of ninth-grade retention. We use a rich 7-year, student-level, panel data set from Arkansas. We use a novel approach by limiting our sample to students who switch schools between eighth and ninth grades. This movement gives each student a fresh…
