A single discrete random variable is depicted by a stick diagram, a 2D picture. Naturally, to visualize a bivariate discrete distribution, one can use a bivariate stick diagram, a 3D picture. Unfortunately, many students have difficulty understanding and processing 3D pictures. Therefore, we construct an alternative 2D disc plot to depict the…

The purpose of this study was to systematically investigate how novice visual representation of design ideas has been operationalized, measured, or assessed in the research literature. In the different screening phases in this systematic review, inclusion, exclusion, and quality criteria were applied. From an initial sample of 958 articles, 40…

Network meta-analysis (NMA) is an established method for assessing the comparative efficacy and safety of competing interventions. It is often the case that we deal with interventions that consist of multiple, possibly interacting, components. Examples of interventions' components include characteristics of the intervention, mode (face-to-face,…

Purpose: The goal of this study is to validate the muscle architecture derived from both ex vivo and in vivo diffusion-weighted magnetic resonance imaging (dMRI) of the human tongue with histology of an ex vivo tongue. Method: dMRI was acquired with a 200-direction high angular resolution diffusion imaging (HARDI) diffusion scheme for both a…

Internal Family Systems (IFS) and art therapy each provide distinctive processes for working within the psychological realm of individuals. Many of their respective goals and techniques are consistent with the underpinnings research finds essential to inform effective trauma care. This article provides an overview of IFS theory and then, through…

The architecture, engineering, and construction (AEC) industry involves substantial requirements for visualization of complex three-dimensional models. There is a significant opportunity to expand the range of tools used to prepare students for this reality, while increasing engagement in the learning process. This study details several potential…

As a response to the increased need for humanization and representation in STEM, a set of open-source, customizable icons was developed using stackable vector graphics to allow participants to design their own research icons. These icons have the potential to both grant research participant's greater agency in their representation and attempt to…

External visualization (i.e., physically embodied visualization) is central to the teaching and learning of mathematics. As external visualization is an important part of mathematics at all levels of education, it is diverse, and research on external visualization has become a wide and complex field. The aim of this scoping review is to…

Universities aim at increasing student retention, with evidence-based and data-based governance of universities becoming best practice. In this context, managing large amounts of data in university management is a challenge. Sankey diagram visualizations of student flows per time unit (e.g. semesters) have been used as method for structuring but…

The current study attempts to investigate whether using multiple diagrams attached to a geometry task could reduce difficulties in the proving process regarding concepts in three-dimensional geometry. Ninety 12th-grade students participated in the study. The research included the use of a questionnaire whose items invited open-ended responses…

Development of graphical methods for representing data has not kept up with progress in statistical techniques. This article presents a brief history of graphical representations of research findings and makes the case for a revival of methods developed in the early and mid-twentieth century, notably ISOTYPE and Chernoff's faces. It resurrects and…

Visual representations, such as diagrams, are known to be valuable tools in problem solving and proof construction. However, previous studies have shown that simply having access to a diagram is not sufficient to improve students' performance on mathematical tasks. Rather, students must actively extract information about the problem scenario from…

Visual representations of data are widely used for communication and understanding, particularly in science, technology, engineering, and mathematics (STEM). However, despite their importance, many people have difficulty understanding data-based visualizations. This work presents a series of three studies that examine how understanding time-based…

This article introduces an innovative teaching and learning tool called "Edelman Gamblegrams" that aims to help medical learners better understand disorders related to water/plasma tonicity homeostasis, i.e., hyponatremia and hypernatremia. Gamblegrams, named after physician James L. Gamble, are bar diagrams displaying the relative…

Learners in general struggle when working with word problems. South African learners in particular have an added barrier owing to the many official languages that have been legislated. The South African Department of Basic Education, through its curriculum statements, envisages that problem solving will play a fundamental part in mathematics…
