A key indicator of meaningful learning is the quality of contribution to discourse
Sociocultural perspective on learning
“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.”
We look at discourse as a key indicator for learning and explore discourse analysis as a method to identify where and how learning happens.
(Mercer 2004)
Discourse as Indicator of Learning
![Page 3: Discourse-Centric Learning Analytics](https://reader036.fdocuments.in/reader036/viewer/2022062512/554962c5b4c905e94e8b59f4/html5/thumbnails/3.jpg)
Discourse analysis focuses explicitly on language as social action
Discourse and Argumentation
are the tools through which people can
compare their thinking, explore ideas, shape agreement, and identify or solve disagreements.
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)
Discourse as the Tool to Think Collectively

The most established online dialogue environments render discourse chronologically, rather than logically, reflecting most strongly the sequence of contributions rather than their conceptual structure:
for instance a Facebook dialogue….

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.
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.

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

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.
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.
Using the Cohere system as an experimental vehicle, we have presented examples of learning analytics to better understand:
learners’ attention
learners’ rhetorical moves within the online discussion
learning topics distribution
learners’ social interactions
