This study evaluated acquisition, preference, and generalization of two forms of augmentative and alternative communication (AAC) during functional communication training (FCT) with two students with autism spectrum disorder (ASD). Acquisition of FCT responses, using a picture-based communication system and speech-generating device (SGD; Apple…

This replication study seeks to extend the generalizability of an exploratory study (McDonough et al., 2019) that identified holds (i.e., temporary cessation of dynamic movement by the listener) as a reliable visual cue of non-understanding. Conversations between second language (L2) English speakers in the Corpus of English as a Lingua Franca…

A well-developed mental model is crucial for effectively studying physiology core concepts. However, mental models can be difficult for students to represent and for instructors to evaluate and correct. Systems modeling as a visualization cognitive tool may facilitate mental model development. On the other hand, evidence of mental model…

This paper explores the relationship between embodiment and visual representations of racial diversity on university campuses. The study analyzes the visuals found on the websites of international student offices at all twelve Swiss universities. Using a discourse theoretical approach as a basis for qualitative document analysis, the paper…

In this paper we summarize the work of Henderson et al. who suggest a foursquare diagram that looks at change on two different dimensions so that an appropriate change strategy can be selected. Operationalizing such changes can be facilitated through the Accelerating Systematic Change Network (ASCN) Change Dashboard. We briefly introduce this…

Digital communicational technologies, such as WhatsApp, have been part of schools both before and during the pandemic. This article explores the normative emergence of being a student, a parent, and a teacher in the use of parents' WhatsApp groups. In Chile, this digital application is widely used by the population, and it is particularly…

The thriving developer community has a significant impact on the widespread use of R software. To better understand this community, we conducted a study analyzing all R packages available on CRAN. We identified the most popular topics of R packages by text mining the package descriptions. Additionally, using network centrality measures, we…

Students with specific learning disabilities (SLD) represent between 5% and 10% of the total number of students in public schools in Saudi Arabia (Abu Nayyan, 2015). Further, 80-90% of students with SLD exhibit reading difficulties including difficulties in reading comprehension (Mercer & Pullen, 2009). Although there is a large number of…

There is limited research concerning the use of visual materials for academic learning in Chinese undergraduate international students' experiences of studying in the United States. To help address this gap, drawing upon theoretical perspectives on multimodality and a literature review on using visual resources, this article discusses the ways in…

New forms of visualizations are transforming how people interact with data. This dissertation explored how undergraduates learn with infographics. The following questions guided this research: (i) What do we know about the factors influencing the processing of data visualizations? (ii) How do task-level and learner-level characteristics impact the…

Molecular representations that show chemical bonding are ubiquitous in general and organic chemistry. These help in communicating chemistry concepts that are fundamental to understanding "how" and "why" molecules interact. The goal of this dissertation work is to offer an evidence-based report on the affordances and limitations…

Data literacy has become a much sought after skill by organizations as the importance of data driven decision making continues to rise in importance. This study explores the teaching of Tableau as a supplement to Excel to enhance the data literacy skills of students. Twenty-eight students taking an introductory course in Business Analytics and…

This study applies human-centered design principles and involves end users in creating a usable knowledge graph. The aim was to explore the potential advantages of capturing and presenting networked knowledge in a domain for information discovery and decision-making purposes. The case taken for the research is the interdisciplinary Ph.D. program…

Here, students determine the total protein content in whey protein samples using the Lowry assay. Quantitative analysis was carried out using absorbance measured at 750 nm (standard method) and 96-well-plate digital images obtained using smartphones (proposed method). The proposed method was carried out using two smartphones (1 and 2). Smartphone…

The year 2020 will be remembered as the year of COVID-19 and its subsequent lockdowns. The time to return to face-to-face teaching has arrived, but the shadow of the disease still hangs over teachers, students, and society. Disruption in teaching can still occur for students, or even teachers, if they are either diagnosed as COVID-19 positive or…
