Two experiments were conducted using match-to-sample methodologies in an effort to model lexical classes, which include both arbitrary and perceptual relations between class members. Training in both experiments used a one-to-many mapping procedure with nonsense syllables as samples and eight sets of abstract stimuli as comparisons. These abstract…

Virtual Reality (VR) is primarily a visual technology. Elements such as haptics (touch feedback) and sound can augment an experience, but the visual cues are the prime driver of what an audience will experience from a VR presentation. At its inception in 2001 the Centre for Advanced Visualization (CFAV) at Niagara College of Arts and Technology…

We describe two experiments on signaling and detecting uncertainty in audiovisual speech by adults and children. In the first study, utterances from adult speakers and child speakers (aged 7-8) were elicited and annotated with a set of six audiovisual features. It was found that when adult speakers were uncertain they were more likely to produce…

This exciting new way of teaching high school/college chemistry combines music, visual aids, and chemical experiments in multi-sensory lessons that motivate students and provide them with meaningful learning experiences in science. The method, known as the Chemical Sensation Project, acknowledges that some individuals learn by seeing or hearing,…

Although the literature on reinforcement in behavioral psychology is extensive, few studies have examined the derived transformation of reinforcing functions in accordance with equivalence classes, and no published research has yet examined the derived transformation of consequential functions in accordance with nonequivalence relations. In the…

This article describes two studies that examined the effects of pictorial and written annotations on second language (L2) vocabulary learning from a multimedia environment. In both studies, students were randomly assigned to one of four aural multimedia groups: a control group that received no annotations, and three treatment groups that provided…

In this article the focus is on methodology for analysing learner-learner oral conversations mediated by computers. With the increasing availability of synchronous voice-based groupware and the additional facilities offered by audio-graphic tools, language learners have opportunities for collaborating on oral tasks, supported by visual and textual…

For the thirty-sixth 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 annual AECT Convention in Anaheim, California. The Proceedings of AECT's Convention are published in two…

The 2007 meeting of the English Think Tank published here represents a sample of the English Think Tank V presentations. In reading these papers one is struck by the imagination and expertise possessed by so many members in the field. The paper topics fall roughly into four categories--assessment, diversity, literacy, and technology. This…

Two experiments investigated the effectiveness of computer-assisted prosody training, its generalization to novel sentences and segmental accuracy, and the relationship between prosodic and lexical information in long-term memory. Experiment 1, using a pretest-posttest design, provided native English-speaking learners of French with 3 weeks of…

As a part of the teacher licensure program at the graduate level at The University of Tennessee at Chattanooga (UTC), the M.Ed. Licensure candidate is required to complete an action research project during a 3-semester-hour course that coincides with the 9-semester-hour student teaching experience. This course, Education 590 Culminating…
