Keynote: Technology Support for Effective Team-Based Learning in Online Education
Prof. Carolyn Rosé
Bio: Dr. Carolyn Rosé is a Professor of Language Technologies and Human-Computer Interaction in the School of Computer Science at Carnegie Mellon University. Her research program is focused on better understanding the social and pragmatic nature of conversation, and using this understanding to build computational systems that can improve the efficacy of conversation between people, and between people and computers. In order to pursue these goals, she invokes approaches from computational discourse analysis and text mining, conversational agents, and computer supported collaborative learning. Her research group’s highly interdisciplinary work, published in over 200 peer reviewed publications, is represented in the top venues in 5 fields: namely, Language Technologies, Learning Sciences, Cognitive Science, Educational Technology, and Human-Computer Interaction, with awards or award nominations in 3 of these fields. She serves as Past President of the International Society of the Learning Sciences and Executive committee member of the Artificial Intelligence in Education Society. She has served as program co-chair for numerous international conferences, workshops, and symposia. She also serves as Executive Editor of the International Journal of Computer Supported Collaborative Learning and Associate Editor of the IEEE Transactions on Learning Technologies.
Abstract: Computational Discourse Analysis is an active area of Learning Analytics that offers real time insights into social processes that impact learning and performance in online courses. This talk reports on research that leverages this important area of research, specifically in connection with a key discussion property referred to as Transactivity. In particular, this talk reports on work towards achieving persistent social interaction throughout large online courses in the form of technology-supported team based projects. We propose what we refer to as a deliberation-based team formation procedure to improve the selection and initiation process used to start team-based learning in an effective way. Results from validation studies demonstrate that project teams formed through this technology-enhanced process are more successful at a collaborative knowledge integration task. Data from deployment studies in real MOOCs are consistent with these findings and demonstrate the potential of this paradigm for real world impact. Implications for promising new directions in online group learning will be explored.

Abstract: Technology advances have made the ability to collect large amounts of data easier than ever before resulting in massive datasets. These massive datasets provide both opportunities and challenges for many fields, and education is no different. Understanding how to deal with extreme amounts of student data is one of the major challenges in educational research today. Although this challenge presents many obstacles, the opportunities to harness big data to make major gains in educational efficiency is also attainable. One area that is especially attractive to the use of big data is adaptive educational systems. Data mining techniques can suggest improvements to the models which drive these systems increasing the overall efficiency of student learning leading to a significant savings in time needed for students to learn.
There will also be some Normal talks:
TEAMMATES: A Flexible Feedback Management System for Education
Dr. Damith C. Rajapakse
National University of Singapore
Abstract: TEAMMATES is an online tool for managing feedback paths in education (e.g. peer feedback among team members). While most Learning Management Systems (LMS) have some support for managing feedback paths, TEMMATES aims to compliment the primary LMS with more flexible and more powerful feedback path management. TEAMMATES can facilitate feedback sessions for instructors and students to submit responses for a set of questions, as done in typical online survey tools. But unlike in typical survey tools, each question in TEAMMATES can have its own feedback path (i.e. who is answering the question about who) and visibility settings (who can see the responses). TEAMMATES is available as a free service from http://TeammatesOnline.info. At June 2017, TEAMMATES user community spanned 175,000 users from over 600 universities.
Theatre performances as data: implications for research and teaching
Dr. Miguel Escobar Varela
National University of Singapore
Bio: Miguel Escobar is a theatre scholar, web programmer and translator. His main interests are the digital humanities and Indonesian performance practices. In his research, he applies computational methods to the study of performance and codes interactive platforms to share theatre scholarship online. He is currently Assistant Professor at the National University of Singapore and director of the Contemporary Wayang Archive (cwa-web.org). He also coordinates Digital Humanities events in Singapore (digitalhumanities.sg). More information is available at miguelescobar.com
Abstract: This talk gives an overview of projects where theatrical performances were used as sources of data. Video, motion capture and linguistic transcriptions of performances can be used for computational research and also for interactive museum exhibits and other creative projects. Thinking about theatre as data opens up new possibilities for interdisciplinary collaborations but it also creates a challenge for teaching. How to prepare students for this kind of work?

Abstract: Collaborative argumentation has been widely recognized as an effective approach for science education as it helps students understand the nature of science, promotes deeper learning of content and enhances knowledge creation. However collaborative argumentation rarely takes place in school because teachers and students lack support in evaluating and reflecting the scientific argumentation. Understanding the significance of both “learning to argue” and “arguing to learn”, this project aims to develop real time automated assessment on both cognitive argumentation and social participation for collaborative argumentation through multi-dimensional learning analytics and visualization. With timely and appropriate assessment and visualization, productively collaborative argumentation processes can be engendered, and the group can be guided to function effectively and efficiently.
