Empower E-learning with Visual Analytics
In the era of big data, the rich data accumulated by the online learning industry have brought new inspirations to instruction intelligence and tutorial services. Processing vast amounts of information into knowledge and improving data utilization capabilities have become opportunities for these new inspirations. Visualization has a direct and close connection with knowledge expression and is an important means of interpreting complex data.
We are E-Learning group of HKUST VisLab. In order to help educators have a deeper understanding of students' online learning behavior and performance, we have explored this study for years and published many related work in this field. We also build some useful open-source techniques on user behavior data collection, online course data visualization and etc. If you have interests in our works, please feel free to contact us.
Educational areas data, such as online tutorial videos and students' interaction records, are all our playgrounds to provide instruction intelligence via visual analytics.
Advanced data mining and deep learning models guarantee us to tackle with billions of course videos and interaction logs extracted from different E-Learning platforms.
Except the basic visualization representation, we introduce and empower visual anlytics to facilitate instruction intelligence.

We developed novel visualization techniques to help domain experts to analyze large-scale data of MOOCs. It provides course instructors and education analysts with intuitive, interactive and detailed analysis of the MOOC data including clickstream data when students interact with course videos, grading data for assignments and exams, and forum data. More specifically, our data visualization techniques help users explore the MOOC data from the following perspectives: video popularity, click stream analysis, demographic distribution, user forum interactions, dropout analysis and sequence analysis. Multi-exploration techniques are offered for analysis at different levels. With the help of our data visualization techniques, course instructors/designers and learning analysts can conduct detailed exploration of the learners’ learning behaviors in an intuitive way, gain deep insights into the students’ learning behaviors and further improve their course designs with evidence-based guidance.
We developed a general interaction data collection technique, which could collect students' fine-grained mouse movement data during the problem-solving process, and deployed the techinique on a K-12 resource-based E-Learning platform since the early 2019 to collect data for research. Based on the collected data, we analyzed the detailed problem-solving sequences and built several novel and intuitive visualization systems, such as QLens and SeqDynamics, which aim at help the platform to infer students' cognitive state in the dynamic problem-solving process. What's more, we extracted the interaction features from students' mouse movement trajectories to predict their performances on any given questions and recommend personalized learning paths.
We have conducted extensive research on online learning and below is a list of our recent papers that are supported by this E-learning project.
