Transcript of "Discourse-Centric Learning Analytics"

  1. 1. LAK2011: 1st International Conference on Learning Analytics and Knowledge February 27-March 1, 2011<br />Banff, Alberta<br />Discourse-Centric <br />Learning Analytics<br />Anna De Liddo, Simon Buckingham Shum, <br />Ivana Quinto, Michelle Bachler, Lorella Cannavacciuolo<br />Knowledge Media Institute, The Open University<br />Business & Management Engineering, Universita’degli Studi Napoli Federico II, Italy<br />cohere.open.ac.uk<br />
  2. 2. A key indicator of meaningful learning is the quality of contribution to discourse<br />Sociocultural perspective on learning<br />“highlights the possibility that educational success and failure may be explained by the quality of educational dialogue, rather than simply in terms of the capability of individual students or the skill of their teachers.” <br />We look at discourse as a key indicator for learning and explore discourse analysis as a method to identify where and how learning happens. <br />(Mercer 2004)<br />Discourse as Indicator of Learning<br />
  3. 3. Discourse analysis focuses explicitly on language as social action <br />Discourse and Argumentation <br />are the tools through which people can<br />compare their thinking, explore ideas, shape agreement, and identify or solve disagreements.<br />If discourse is the tool through which learners think collectively, then discourse outcomes and discourse analysis can provide indicators to better understand the learning processes (Mercer 2000)<br />Discourse as the Tool to Think Collectively<br />
  4. 4. Discourse Analysis to Better understand the Learning Process<br />What Discourse Environment?Chronologically VS LogicallyRendered Dialogue Environments <br />The most established online dialogue environments render discourse chronologically, rather than logically, reflecting most strongly the sequence of contributions rather than their conceptual structure:<br />for instance a Facebook dialogue….<br />

  11. 11. Discourse Analysis to Better understand the Learning Process in Cohere<br />we discuss what it mean to use Cohere’s online dialogue environment to monitor online learning activities and develop useful learning analytics, by starting on the analysis of the online discourse which learners are involved in.<br />We demonstrate how discourse analytics can enable a deeper understanding of the online discourse, of the participants to the discourse and the social and learning dynamics.<br />

  13. 13. Table on Posts’ Type -> Learner Attention and Performance<br />By looking at the post type table it is possible to evaluate learner’s performance connecting the discourse outcomes with the specific learning goal.<br />

  29. 29. We have motivated a focus on learners’ discourse as a promising site for identifying patterns of activity which correspond to meaningful learning and knowledge construction. <br />We are interested in the rhetorical role that a user’s contribution is making to a document or conversation and the nature of the connection to other contributions using semantic relationships. <br />Using the Cohere system as an experimental vehicle, we have presented examples of learning analytics to better understand:<br />learners’ attention<br />learners’ rhetorical moves within the online discussion<br />learning topics distribution<br />learners’ social interactions<br />Conclusions<br />
