This study addresses teachers' activity when working with digital technologies (DT) in their classrooms. We build upon a model that considers teaching as managing "open dynamic situations." Within the model, teachers' activity is viewed as diagnosing students' mathematical activity, managing uncertainties due to the characteristics of…

There is an increased need for leadership development in higher education around the world. Reported in this paper is an explorative higher education leadership development program developed from an international comparative perspective. This ongoing program is offered to Chinese university administrators at a Canadian university since 2012. This…

Predicting students at risk of academic failure is valuable for higher education institutions to improve student performance. During the pandemic, with the transition to compulsory distance learning in higher education, it has become even more important to identify these students and make instructional interventions to avoid leaving them behind.…

In this article, a tripartite interpersonal model is proposed to analyze academic lectures delivered in English. The model combines two approaches to metadiscourse: the reflexive or narrow approach (Mauranen 1993; Ädel 2006), and the interpersonal or broad approach (Hyland 2005, 2019). The criteria adopted by the reflexive approach were exploited…

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,…

Over the past decade or so, developments in language comprehension research in the domain of cognitive aging have converged on support for resilience in older adults with regard to situation model updating when reading texts. Several studies have shown that even though age-related declines in language comprehension appear at the level of the…

Hybrid autoregressive-latent growth structural equation models for longitudinal data represent a synthesis of the autoregressive and latent growth modeling frameworks. Although these models are conceptually powerful, in practice they may struggle to separate autoregressive and growth-related processes during estimation. This confounding of change…

Dr. Elfreda Chatman was a professor of library and information science at the University of North Carolina and Florida State University in the 1990s and early 2000s until her passing in 2002. Her research incorporated the disciplines of education, sociology, and LIS, covering topics at the nexus of these fields, from which she worked to develop a…

The majority of the scholarly work on school leadership over the past several decades has centered on issues of academic press, while matters involving the social development and support of students have received far less attention. We know that improving students' relationships with teachers has important, positive and long-lasting implications…

The current research empirically examined the developmental networks of female workers and how the network configurations influence their subjective career success, with particular attention to the gender and status composition of the network along with other network characteristics. Data from 427 female workers with a college degree or higher in…

Servant leadership has been proposed as a highly relevant approach to leadership in the higher education context. However, little is known about its contribution to desirable organizational outcomes in academic settings, and even less is known about the role that servant leadership's multidimensionality plays. Consequently, our study aims to…

While research suggests that mathematical modeling is accessible to elementary grade students, questions remain about how to assess modeling competency. Our research addresses this need through the systemic design and empirical testing of a Mathematical Modeling Student Assessment (MMSA) for elementary grades 3 through 5. Research questions focus…

In this article, I present the eighteenth century's polemic of Bernoulli and d'Alembert concerning the smallpox epidemic and a prevention method called inoculation. Through an analysis of the polemic and the related resources, I show that this historical debate has various interests for mathematics education; and more specifically it can help…

Students with low socioeconomic status (SES) are more likely to leave college without a degree than students with high SES, although there are fewer low-SES students who persist to graduation. The most likely time for students to leave the University is after the first year. The purpose of this qualitative study of low-SES students, both retained…

The presented paper is devoted to the new teaching model of congruences of computer science students within the subject of discrete mathematics at universities. The main goal was to create a new model of teaching congruences on the basis of their connection with Diophantine equations and subsequently to verify the effectiveness and efficiency of…
