Dynamic Knowledge Tracing

Description

Knowledge tracing refers to the problem of modelling knowledge of students over time as they interact with a learning system, which have been studied extensively in computer supported education. However, the knowledge tracing problem is inherently difficult as human learning is grounded in the complexity of both the human brain and human knowledge. Recently, deep neural networks have been successfully used to build several knowledge tracing models, including the Deep Knowledge Tracing (DKT) model developed by the researchers from Stanford University (Piech et al., Deep knowledge tracing, NIPS 2015) and Dynamic Key-Value Memory Network (DKVMN) model ( Zhang et al., Dynamic key-value memory networks for knowledge tracing, WWW 2017),  which have been shown to be able to predict student performance better than the previous knowledge tracing models.

 

Goals

The objective of this research project is to investigate the capabilities of various deep learning
models for knowledge tracing to predict students learning behaviour, aiming to extend these models
to provide real-time personalized learning recommendations for students.
 
 

Requirements

Strong skills in programming (C++, Java or Python) are required. Solid knowledge background in data mining and machine learning are desired.
