Course: 2021: Virtual Meeting, Topic: [Ignite]"The Relationship between Semantic-Similarity-Based Cognitive Diversity and Discussion Effectiveness in An Intelligent Discussion System" by Hongli Gao

About
2021 ALTTAI ANNUAL CONSORTIUM MEETING is an annual international consortium meeting for the dissemination and exchange of educational research on theoretical, generic, and applied areas of education, psychology, computer science/engineering, cognitive science, and their interdiscipline. ALTTAI is the abbreviation of Advanced Learning, Theories, Technologies, Applications, and Impacts Consortium. The annual international consortium meeting can be the upgraded version of our regular weekly seminar.

The overarching goal of the 2021 ALTTAI ANNUAL CONSORTIUM MEETING research community is to provide a collaborative platform for relevant faculty members, graduate students, and industry partners. This meeting will be accomplished through the following three modes of communication: keynote presentation, regular presentation, and ignite presentation.
The related topics include, but are not limited to,
Online and distance learning, Education psychology,
Education technology,
Intelligent and Interactive Technologies in an Educational Context,
Collaborative Learning in Online Environments,
Models of Teaching and Learning,
Evaluation on learning and teaching,
Simulation on learning and teaching,
Inequity and inequality in education.

This meeting will be organized and run as a two-day virtual conference on 30-31 July 2021 (To 1 August, 2021 for BJT). Please mark your calendars and join our 2021 ALTTAI ANNUAL CONSORTIUM MEETING.

  Cognitive diversity has been manipulated as the wide range of semantic categories (Nijstad, Stroebe, & Lodewijkx, 2002), low related categories (Baruah & Paulus, 2016) and so on. However, these kinds of cognitive diversity were determined before group discussion and would not change dynamically during the discussion, which could be called static cognitive diversity. Compared to this, adaptive cognitive diversity was defined as the adaptive difference with the previous semantic domain in group discussion. For manipulation, stimuli which were different from the previous dynamic semantic domain were given after automatically identifying the previous semantic domain in the discussion (Gao, Yang, Xu, & Hu, 2019). Results showed that compared with the homogeneous condition, discussion breadth of the participants increased under the diverse condition, participants subjectively considered that the opinions provided by virtual agents were more helpful and the understanding on the discussion questions was more comprehensive under the diverse condition.
