This study investigated the application of an artificial intelligence (AI) coach for second language (L2) learning in a primary school involving 327 participants. In line with Community of Inquiry, learners were expected to perceive social, cognitive, and teaching presences when interacting with the AI coach, which was considered a humanized…

Certain features of the PLATO IV system allow the gathering of large quantities and varieties of information describing the interaction of students with computer based education courseware. Two kinds of information can be provided: (1) data concerning single student interaction, which must be analyzed manually; and (2) data summarizing activities…

Two information dissemination centers at University of California at Los Angeles and University of Georgia studied the interactions between computer based search facilities and their users. The study, largely descriptive in nature, investigated the interaction processes between data base users and profile analysis or information specialists in…

An information system can be viewed as a symbiotic relation between the users of the system and the system's hardware, software, and data resources. Ideally, performance evaluation of these systems should be based on the achievement of user based criteria while concurrently minimizing resource costs. Current evaluation technologies concentrate on…

The design of five experiments comparing usability evaluation methods (UEMs) is examined. Each has had an important influence on human-computer interaction (HCI); however, problems with experimental design raised questions as to the efficacy of various UEMs. To obtain desired outcomes of the experimental method addressing HCI issues, close…

Human interactions are multimodal in nature. From simple to complex forms of transferal of information, human beings draw on a multiplicity of communicative modes, such as intonation and gaze, to make sense of everyday experiences. Likewise, the learning process, either within traditional classrooms or Virtual Learning Environments, is shaped by…

Examines users' cognitive, affective, and physical behaviors during user-Web interaction to understand better the nature of information retrieval on the Web, the needs of Web users, and the problem-solving strategies Web users employ. Describes and interprets searching behavior and problem-solving patterns within the relevant situational context…

The techniques, procedures, and principal findings of 15 different experiments in a research program on interactive communication are summarized in this paper. Among the principal findings reported are that: problems are solved faster in communication modes that have a voice channel than in those that do not have a voice channel, modes of…

For the thirtieth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the National AECT Convention in Anaheim, California. The Proceedings of AECT's Convention are published in two…
