Introduction

This document summarizes the idea of using Bayesian analysis for keeping track of student learning.

The model discussed here is the Bayesian knowledge tracking (BKT) model originated by Corbett and Anderson [Corbett1995].

Here, we have our eyes on big data. Big data mean real time data as much as a large amount of data. It is conceivable that this type of analysis is run in real time and be used to constructively intervene in a student learning process. The Bayesian method looks promising, while it probably is not the only method.
