Pedagogical Agents’ Personas: Which Affects More, Image Or Voice?, Yanghee Kim, A. L. Baylor, G. Reed Oct 2004

Pedagogical Agents’ Personas: Which Affects More, Image Or Voice?, Yanghee Kim, A. L. Baylor, G. Reed

Yanghee Kim

The purpose of this study was to examine the effects of image and voice of pedagogical agents on student perception and learning. Pedagogical agents were developed with differing image (expert-like vs. mentor-like) and voice (strong vs. calm vs. computer-generated), but with identical gesture, affect, comments, and gender. 109 undergraduates in a computer literacy course were randomly assigned to one of the six conditions. The results revealed a significant main effect for agent image on role perception: the mentor-like image was perceived as more motivating, as hypothesized. Also, there was a significant main effect for voice: the strong voice was overall …

Collaborative Information Filtering: A Review And An Educational Application, Andrew Walker, Mimi Recker, Kimberly Lawless, David A. Wiley

Instructional Technology and Learning Sciences Faculty Publications

This paper reviews the literature surrounding an information filtering technique, collaborative information filtering, which supports the discovery of resources in a way that is sensitive to the context of users. Moreover, via statistical clustering techniques, the system supports automated, personalized filtering and recommendation of relevant resources and like-minded users for particular user communities. The paper also describes an educational implementation of this approach, called Altered Vista, and presents results from a 3-month trial use of the system, aimed at evaluating the educational effectiveness and usefulness of the approach.

Computer-supported coordinated care uses technology to aid the network of people who support an elder living at home. The authors conducted interviews with people involved in the care of elders to identify their needs and subsequently conducted an in situ evaluation of a technology probe to study how a CSCC system might help satisfy these needs. The authors used these results to identify challenges faced by people caring for elders and offer guidelines for designers of coordinated care technologies.

Finding Answers To Complex Questions, Anne R. Diekama, Ozgur Yilmazel, Jiangping Chen, Sarah Harwell, Lan He, Elizabeth D. Liddy

Instructional Technology and Learning Sciences Faculty Publications

In this chapter, we motivate one potential type of future QA system that deals with questions more complex than simple factoid questions and which provides answers with their supporting context. Our approach is based on the issues we faced when developing and delivering a QA system to deal with real time questions in the domain of RLVs within the larger field of aerospace engineering. This particular domain, the actual users of the system, and the questions asked, all demanded a change in our question-answering strategy. First, the chapter will present background on the project that provided the context and a …

Exploring A Cognitive Basis For Learning Spatial Relationships With Augmented Reality, Brett E. Shelton, Nicholas R. Hedley Jan 2004

Exploring A Cognitive Basis For Learning Spatial Relationships With Augmented Reality, Brett E. Shelton, Nicholas R. Hedley

Instructional Technology and Learning Sciences Faculty Publications

Augmented reality (AR) is an emergent class of interface that presents compelling possibilities for advancing spatial visualization. We offer a brief overview of AR technology and current research with in the educational realm. AR interfaces appear to provide a unique combination of visual display properties, modes of user manipulation, and interaction with spatial information. Drawing upon aspects of proprioception and sensorimotor function, we discuss how AR may have a unique and powerful link to spatial knowledge acquisition through visuo-motor involvement in the processing of information. We identify key properties of AR interfaces and how they differ from conventional visualization interfaces, …

Supporting ‘Word-Of-Mouth’ Social Networks Through Collaborative Information Filtering, Mimi Recker, Andrew Walker

Instructional Technology and Learning Sciences Faculty Publications

Altered Vista is an instructional system that supports a form of ‘contextual’ collaborative learning. Its design incorporates an information filtering technique, called collaborative information filtering, which, through computational and statistical means, leverages the work of individuals to benefit a group of users. Altered Vista is designed to provide, upon request, personalized recommendations of Web sites. It can also provide recommendations of like-minded people, thus setting the stage for future collaboration and communication. An empirical study involving in-service and pre-service teachers was conducted using Altered Vista and presents results from an empirical study. The study examined the feasibility and utility of …

Genetics & Your Practice, began in 1994 as a course for primary health care practitioners to get Continuing Medical Education (CME) credits and to help health care providers learn about the importance of genetic counseling and the fundamental difference between genetic counseling and traditional health care. In a collaborative project between the March of Dimes and Idaho State University Departments of Nursing (ISU) and Continuing Education/Special Programs, the course was converted to an online asynchronous course. Since the course was primarily didactic, ISU approached a team of graduate students at Utah State University’s Department of Instructional Technology (USU) to develop …

A Non-Authoritative Educational Metadata Ontology For Filtering And Recommending Learning Objects, Mimi Recker, David A. Wiley Jan 2001

A Non-Authoritative Educational Metadata Ontology For Filtering And Recommending Learning Objects, Mimi Recker, David A. Wiley

Instructional Technology and Learning Sciences Faculty Publications

Digital libraries populated with learning objects are becoming popular tools in the creation of instructional technologies. Many current efforts to create standard metadata structures that facilitate the discovery and instructional use of learning objects recommend a single, authoritative metadata record per version of the learning object. However, as we argue in this paper, a single metadata record — particularly one with fields that emphasize knowledge management and technology, while evading instructional issues — provides information insufficient to support instructional utilization decisions. To put learning objects to instructional use, users must examine the individual objects, forfeiting the supposed benefits of the …

Results From The First World-Wide Web Survey, James Pitkow, Mimi Recker

Instructional Technology and Learning Sciences Faculty Publications

The explosion of World-Wide Web (WWW) across the Internet is staggering, both in terms of number of users and the amount of activity. However, to date, no reliable characterization exists of WWW users. In this paper, we report results from a survey that was posted on the Web for a month, in January of 1994. There were several goals motivating our survey. First, we wished to demonstrate a proof of concept for WWW technologies as a useful survey medium. Second, we wanted to bet a-test the design and content of surveys dealing with the Web. Third, as mentioned, we hoped …
