As higher education institutions go online to reap the benefits of technology and align their programs with a world economy that is increasingly becoming digital, the multimedia learning theory warns of possible challenges. Large device screens have been used to present related information elements of a learning task simultaneously to facilitate…

The purpose of this comparative, longitudinal case study was to explore the distance operations system implemented in U.S. colleges and universities during the COVID-19 pandemic. Embedded in a larger two-year study of distance education in the U.S. before and after the health crisis, this study combined a grounded theory methodology with a…

Learning analytics (LA) dashboards are becoming increasingly available in various learning settings. However, teachers may face challenges in understanding and interpreting the data visualisations presented on those dashboards. In response to this, some LA researchers are incorporating visual cueing techniques, like data storytelling (DS), into LA…

Three experiments examined how bottom-up and top-down processes interact when people view and make inferences from complex visual displays (weather maps). Bottom-up effects of display design were investigated by manipulating the relative visual salience of task-relevant and task-irrelevant information across different maps. Top-down effects of…

The focus of this project was on characterizing and assessing design problem solving in the area of digital circuit design. Think-aloud protocols and computer traces of subject problem-solving behavior were used to elucidate the cognitive processes involved in designing combinational and complex sequential circuits by: (1) studying the differences…

This technical report describes a generic architecture for building intelligent tutoring systems which is developed around objects that represent the knowledge elements to be taught by the tutor. Each of these knowledge elements, called "bites," inherits both a knowledge organization describing the kind of knowledge represented and…

Contains an excerpt from the author's landmark work about the way lay people think about technology and the language they use to express their thoughts. Discusses some of the fundamental differences between common conceptualizations of the way computers work and the way other machines and mechanisms work. (TB)

This report begins by discussing the implications of a constructivist epistemology for instructional design and development, as well as drawbacks of the content database in instruction, the lack of special tools to help the learner actively construct knowledge, and emphasis on learning environments based on individual learning. The whole learning…

Discusses the concept and design of an enriched learning and information environment that was originally developed at Indiana University in partnership with AT&T (American Telephone and Telegraph). Topics addressed include constructivism, cognitive tools, representing expert behavior, apprenticeship, technological tools, information tools,…

This study of 40 undergraduates examined whether aiding as cognitive support (i.e., offering computer users knowledge they are missing) can supplement lack of knowledge and capacity under tasks with high mental loading, such as dealing with irregularities in process control. Users of a railway traffic control simulator dealt better and faster with…

This study examined the effects of the number of links and the granularity of nodes on undergraduate and graduate students' information searching, learning performance, and attitude toward hypermedia systems. Discusses the relationship between the number of links and cognitive overhead an/or disorientation as well as implications for Web-based…
