As asynchronous discussion forums become more prevalent in online and flexible-delivery modes of teaching, understanding the role that instructors play in student learning in these forums becomes an important issue. Whether the instructor chooses to lead discussions or to keep a low profile can affect student participation in surprising ways. In this study, we investigate how instructor partici...

STATEMENT Better debriefing practices may enhance the impact of simulation-based education. Emerging literature suggests that learner-centered debriefing may be effective in helping instructors identify and address learner needs while building learner's engagement and sense of responsibility for learning. This contrasts with instructor-centered approaches to debriefing, where instructors mainta...

Formative assessment can encourage an instructor to improve learning achievements in a lecture class. The goal of formative assessment in a classroom situation is monitoring learners to provide instructor’s feedback for improving learner’s understanding as well as instructor’s expectation. A Kit-Build concept map is a digital tool for supporting a concept map strategy to represent instructor’s ...

This paper describes the evaluation of a speech-driven cartoon agent that has been embodied in the interface of a Web-based Intelligent Tutoring Systems (ITSs) authoring tool. The agent is mainly used in the student interface of the ITSs that are produced by the authoring tool and represents either a student or an instructor. The agent was evaluated during an experiment in terms of the effect t...

Instruction giving can be used in several applications, ranging from trainers in simulated worlds to non player characters for virtual games. In this paper we present a novel algorithm for rapidly prototyping virtual instruction-giving agents from human-human corpora without manual annotation. Automatically prototyping full-fledged dialogue systems from corpora is far from being a reality nowad...

This paper reports research on the implementation of a web-based videoconferencing tool (Interwise) for synchronous learning sessions on an industrial technology course offered through a university in northern Taiwan. The participants included undergraduate students from the same course offered in two different semesters. We investigated students' perceptions of interactions with the instructor...

Background. Teaching direct laryngoscopy is limited by the inability of the instructor to simultaneously view the airway with the laryngoscopist. Our primary aim is to report our initial use of the GlideScope Direct, a video-enabled, Macintosh laryngoscope intended primarily as a training tool in direct laryngoscopy. Methods. The GlideScope Direct was made available to anyone who planned on per...
