The purpose of this study was to investigate the effects of an iPad iBook for adolescents with disabilities. With its release in 2012, the iBooks Author software for the Apple iPad allows classroom teachers to create accessible and engaging textbooks. Leveraging media and interactive widgets, iBooks Author holds promise for delivering content to…

Mobile learning is a cognitively demanding application and more frequently the ubiquitous nature of mobile computing means that mobile devices are used in cognitively demanding environments. This paper examines the nature of this use of mobile devices from a Learning, Usability and Cognitive Load Theory perspective. It suggests scenarios where…

When using modern educational technology, some forms of instruction are inherently transient in that previous information usually disappears to be replaced by current information. Instructional animations and spoken text provide examples. The effects of transience due to the use of animation-based instructions (Experiment 1) and spoken information…

Background: Context-based learning approaches are used to enhance students' interest in, and knowledge about, science. According to different empirical studies, students' interest is improved by applying these more non-conventional approaches, while effects on learning outcomes are less coherent. Hence, further insights are needed into the…

Universal Design for Learning (UDL) is a framework that is commonly used for guiding the construction and delivery of instruction intended to support all students. In this study, we used a related model to guide creation of a multimedia-based instructional tool called content acquisition podcasts (CAPs). CAPs delivered vocabulary instruction…

There is abundant educational research indicating that graphic organisers (knowledge maps, concept maps, or mind maps) have a beneficial impact on learning, but hardly any research has examined this in the context of presentations. This study therefore investigated how graphic organisers -- as delivered via presentation software -- affect learning…

Animation has an inherent advantage over static graphics when presenting dynamic content because it provides a more accurate and realistic depiction. Simultaneously, animation has an inherent disadvantage because most animated information is perceptually transient. In this quasi-experimental study, cognitive load theory was used to investigate the…

This study investigated whether arrow-line cues can improve the effectiveness and efficiency of learning in a mobile device supported learning environment on leaf morphology of plants, either with or without the use of real plants. A cued and un-cued condition, in which primary school students used text and pictures on a tablet PC, were compared…

Cognitive load theorists claim that problem-centered instruction is not an effective instruction because it is not compatible with human cognitive structure. They argue that the nature of problem-centered instruction tends to over-load learner working memory capacity. That is why many problem-centered practices fail. To better support students and…

This study analyzes the uses of real-world contexts in mathematics lessons in the classrooms of four teachers across two school years at an urban high school. Drawing upon a framework of culturally relevant mathematics pedagogy, this dissertation focuses on how real-world contexts are connected to teaching mathematics for understanding, centering…

The etiology of persistent stuttering is unknown, but stuttering has been attributed to multiple potential factors, including difficulty in processing language-related information, but findings remain inconclusive regarding any "specific" linguistic deficit potentially causing stuttering. One particular challenge in drawing conclusions is the…

Variations in perceptual and cognitive demands (load) play a major role in determining the efficiency of selective attention. According to load theory (Lavie, Hirst, Fockert, & Viding, 2004) these factors (a) improve or hamper selectivity by altering the way resources (e.g., processing capacity) are allocated, and (b) tap resources rather than…

The Latin Square Task (LST) was developed by Birney, Halford, and Andrews [Birney, D. P., Halford, G. S., & Andrews, G. (2006). Measuring the influence of cognitive complexity on relational reasoning: The development of the Latin Square Task. Educational and Psychological Measurement, 66, 146-171.] and represents a non-domain specific,…

Schmeichel (2007) reported that performing an initial task before completing a working memory span task can lower span scores and suggested that the effect was due to depleted cognitive resources. We showed that the detrimental effect of prior tasks depends on a match between the stimuli used in the span task and the preceding task. A task…

Civic teachers are members of their community and are responsible for preparing their students to be future citizens. West Virginia is one of nine states that requires students to pass a class whose title includes the word "civic." All 12th grade students in the state must take a year long civic education course. The goal for the course…
