About the Workshop
Nowadays online discussions and drawing of concept maps are two very common pedagogical designs used by teachers in learning activities. However, keeping track of ideas progression in forums or evaluating concept maps produced by students is a big challenge to teachers who may not have time to read all posts, as well as students who may not have the knowledge to conduct meta-level evaluation to improve their outcome of learning.

The goal of this workshop is to introduce and explore analysis methods that may generate meaningful insights onto these kinds of activity data in order to help teachers or researchers to evaluate students’ engagement and learning. For online discussion forum data, an algorithm base on HLDA on detecting and studying topic evolution in forum postings over a period of time will be presented. For concept maps, the statistical approach and semantic technology were used to mine the concept map for scaffolding users to draw concept map, and possibly evaluate the degree of similarity of concept maps between expert and students. It is hoped that these analysis methods may contribute towards development of assessment tools that can be used by teachers and students to assist learning in online platforms.
