This qualitative multiple-case study provides insight into the experiences of English language learners (ELLs) attending classes in a community college setting. Community colleges in the US play a significant role in the access to higher education for ELLs, a sizable student population that includes US high school graduates, adult immigrants,…

The increasing complexity of modern power systems, coupled with the integration of diverse rapidly evolving technologies involving physical systems requiring cybersecurity, has presented significant challenges for engineers in the field and researchers in laboratory facilities. This research and dissertation presents the development of a…

Social media platforms play important roles in many educators' lives. In particular, teacher professional activities on Twitter have received attention from scholars. However, research has not typically explored Twitter use with attention to the diverse national contexts in which teachers work. To address this literature gap, the present…

Background/Context: As a major area of civic decision making, public education is a central arena for advocacy groups seeking to influence policy debates. An emerging body of research examines advocates' use of social media. While debates about policy can be thought of as a clash of large ideas contained within frames, cognitive linguists note…

There are few studies devoted to analyze the relationships between the structure of the social network and performance in the online learning process as group. In this study, the Community of Inquiry (CoI) model is used as an analytical framework, along with quantitative content analysis and social network analysis, in order to identify the effect…

Comprehensive institutions (CIs) have long been characterized as middling universities with a confused identity and purpose. Yet, their historical origins demonstrate that they have served as an important point of access into higher education for marginalized student groups. Still, there remains little consensus over which institutions are CIs and…

Over the last 20 years, online peer review and assessment have become widely used and well-researched practices in education. Their use increased, especially with the proliferation of nonconventional large-scale and online modes of teaching and learning, such as Massive Open Online Courses (MOOCs). A well-designed peer-review system is expected to…

Agent-based modeling holds great potential as an analytical tool. Agent-based models (ABMs) are, however, also vulnerable to critique, as they often employ stylized social worlds, with little connection to the actual environment in question. Given these concerns, there has been a recent call to more fully incorporate empirical data into ABMs. This…

This study investigates the dynamic interplay between bullying relationships and friendships in a sample of 481 students in 19 elementary school classrooms (age 8-12 years; 50% boys). Based on a relational framework, it is to be expected that friendships would be formed when two children bullied the same person and that children would start to…

Context: Individuals' curation within social media provides a window into their sensemaking and conceptions of what is worth knowing. Within education, a majority of teachers use social media for professional purposes to access and share instructional resources. Purpose: This work examines Pinterest.com and the intersection of influence across…

This study models how new ideas, practices, or diseases spread within and between communities, the diffusion of innovations or contagion. Several factors affect diffusion such as the characteristics of the initial adopters, the seeds; the structure of the network over which diffusion occurs; and the shape of the threshold distribution, which is…

Open digital badges are new credentials that can contain specific claims and links to web-enabled evidence, and can then circulate in networks. Badges are helping facilitate broader shifts away from measuring, accrediting, and credentialing "achievement" and towards capturing, validating, and recognizing "learning." A study of…

Collaborations between Extension and nonprofit organizations have the potential to increase programmatic outcomes and generate revenue. One challenge in establishing such collaborations is identifying potential collaborators. We organized a structured networking workshop to foster such relationships. Of 28 participants, 24 completed the…

Reading comprehension requires readers to connect ideas within and across texts to produce a coherent mental representation. One important factor in that complex process regards the cohesion of the document(s). Here, we tackle the challenge of providing researchers and practitioners with a tool to visualize text cohesion both within (intra) and…

Continuing racial inequities and marginalization have led some communities to reject reliance on public schooling by forming their own programmes and/or schools, claiming sovereignty over the education of their children. We highlight Freedom Schools as one such ongoing but under-studied movement that precedes and contributes to recent,…
