The Models and Modeling Working Group at PME-NA has provided a forum for discussing and collaborating on projects fundamental to research on mathematical modeling since the first PME-NA conference in 1978. We propose to convene this Working Group at PME-NA 41 with a dual purpose: (1) to build on a theme begun in Greenville, holding a focused…

In this article we present and discuss some theoretical and methodological elements of a wider research that analyzes the teaching practice of two teachers novice and expert from a semiotic theoretical approach. The conceptual framework of this work allows for addressing the epistemological and didactic dimensions of the teaching practice. Three…

Despite the importance of rehearsal to most models of verbal working memory, its role has been recently called into question. Much prior work in support of rehearsal models has centered on the experimental effects of word-length, phonological-similarity, and irrelevant sound on serial order recall performance and the interaction of all three with…

This study, aimed at supporting the work of assessing college students' spiritual formation in Christian higher education, looked at relevant empirical studies from psychology of religion and higher education student development. The review of the literature allowed the researcher to identify findings about college students' religiousness and…

Building information modeling (BIM) has been a disruptive development in the global architecture, engineering, construction and operations (AECO) industry. While architecture schools have sought to integrate BIM into their curricula, most current pedagogical approaches and lessons are derived from engineering and construction management…

Objective: This study examines how accurately a small set of short-term academic indicators can approximate long-term outcomes of community college students so that decision-makers can take informed actions based on those indicators to evaluate the current progress of large-scale reform efforts on long-term outcomes, which in practice will not be…

This study compares an ideal model of a sustainable research institution and the dominating model used by Sida. It uses a complementary capacity building (CCB) model aimed to promote an improved research culture for strengthening the sustainability of research partnerships in economics and management disciplines. This study uses bibliometric data…

As digital technology is becoming an increasingly critical component of education, learners' socioeconomic status (SES) and technology use are becoming more important in their learning. In the context of English learning, the present study modeled how learners' SES and their perception of technology use for language learning are linked to their…

Unidimensionality is an important assumption of measurement but it is violated very often. Most of the time, tests are deliberately constructed to be multidimensional to cover all aspects of the intended construct. In such situations, the application of unidimensional item response theory (IRT) models is not justifieddue to poor model fit and…

This article details the development of design principles to support teachers in planning for a Community-Based Mathematical Modeling task with a focus on social justice in the elementary grades. By reflecting on the dilemmas we encountered in the design and enactment of the tasks, we developed five design principles that allowed us to address…

In spite of its increasing popularity, distance education faces challenges -- levels of digital literacy, access to technology, workload and time management, students' feelings of isolation and disconnection -- that can have a significant impact on the experience of the learners. In addressing these issues, we propose a pedagogical model for…

Traditionally, many English language teachers around the world have conformed to an English as a foreign language (EFL) model. In this model, they expose their students to the standard language norms of English-dominant nations, such as the United States and the United Kingdom. However, English learners do not only need language skills to…

Little is known about how the expansion of state pre-kindergarten (pre-k) programs affects low-income children with disabilities in Head Start. Using almost 30 years of administrative data of all Head Start programs and a differences-in-differences design, this study tests the possibility that, as state pre-k differentially draws relatively more…

The doctoral journey is a complex endeavour, and like any complex project, deserves to be managed accordingly. Agile Project Management has been used successfully by practitioners in the Software industry for the last two decades and recently is being adopted in other industries, including in Higher Education. Based on the author's personal…

In the "Bilingual Literacy Development Model: A holistic way to support Spanish-speaking children" research study, I studied bilingual families over a 5-month period in their home environments through home visits. Drawing from data obtained through home visits, including interviews with mothers and observations of family literacy…
