Learning involves complex cognitive processes such as perception, attention, and memory, with reading being a common method to acquire knowledge. Textbooks are often supplemented with additional materials such as self-test questions and demonstration tasks to enhance learning. However, the impact of these supplemental materials, especially when…

Graph data, especially large graph data, come up in many domains, such as social networks, the map of science, biological data, and even knitting! This presents a problem when we consider visualizing these structures. Layouts must be chosen carefully so that the structure of the graph is visible. Some graphs are large enough and connected enough…

Most college students take lecture notes to prepare for tests. With technology development, more students are recording notes on laptops rather than writing them longhand. Previous studies comparing laptop and longhand note taking mediums yielded mixed results, highlighting the need to identify influencing factors. The present study investigated a…

Unlike desktop computers, reading in virtual reality allows the reader and the information to cohabit in the three-dimensional space. However, virtual reality typography rarely exploits the new affordances three-dimensionality offers. This study addressed the need to understand the contributions of spatially distributed layouts on expository text…

The purpose of the study is to enumerate the representations in high school geometry, to narrow the focus to the most common ones, and to describe how the common representations are coordinated. To achieve this purpose, I analyzed several sections of a popular geometry textbook using thematic analysis, semiotics, and a pragmatic approach to…

In team-based medical tasks, digital tools facilitate information among medical experts to support patient safety. Although generally beneficial, Electronic Health Records (EHRs) have not completely mitigated communication and clinical decision errors. The design of systems meant to facilitate information-transfer among care teams has been…

Semantic illusions are recognition errors that occur when an individual fails to notice that information contradicts their prior knowledge (Barton & Sanford, 1993; Erickson & Mattson, 1981). For example, after hearing the question, "If a plane crashes while flying over state lines, where should the survivors be buried?" many…

This study investigated the effect of font style and character spacing on reading performance of 25 second graders, measured by an oral reading fluency test. The effect of font type and character spacing on reading performance was analyzed with ANOVA. Font style did affect reading performance. Character spacing may be relevant for longer reading…

This mixed methods study evaluated the strengths and weaknesses of Colorado's special education procedural safeguard notice (CPSN) through readability and design factors. Per IDEA, procedural safeguard notices must inform families of children with disabilities of their rights within special education. Local education agencies (LEAs) distribute the…

People often use different types of available information as cues to make inferences about memory (Koriat, 1997). When these cues are unreliable predictors of memory (like font size), metacognitive illusions can ensue (Mueller, Dunlosky, Tauber, & Rhodes, 2014). Extending upon Rhodes and Castel's (2008) findings that perceptual fluency cues…

The purpose of this research was to analyze one 2nd grade teacher's instructional practices as she helped her students co-construct an understanding of nonfiction as a genre. Research was conducted over the course of 14 weeks with 22 students and one teacher. Data were collected from videos of large and small group instruction; videos of the…

This Glaserian grounded theory study, through conceptual coding of interviews and course syllabi, aimed at exploring the motivations and aspirations university professors had when they offered courses dedicated to the study of graphic novels. As a result, the emergence of the graphic novel as a vital literary influence in 21st-century academia was…

The emergence of standards-based curriculums has resulted in an increased frequency of student testing, including high-stakes testing. Of students who take tests, up to 65% may experience test anxiety, which can have negative effects on student outcomes. For this reason, the purpose of this single-group, repeated measures design, quantitative…

In five experiments, I investigated how readers and listeners generate relevant contrasts in comprehending and remembering discourse. Past work has suggested that prominent words promote encoding of salient alternatives and that this benefits later memory, but it is unclear exactly which alternatives are considered or how consistent these benefits…

The size and dynamism of the Web poses challenges for all its stakeholders, which include producers/consumers of content, and advertisers who want to place advertisements next to relevant content. A critical piece of information for the stakeholders is the demographics of the consumers who are likely to visit a given web site. However, predicting…
