Automatically Generating Questions in Multiple Variables for Intelligent Tutoring

Abstract

In our previous research, we investigated the automatic generation of questions with single variable and the application to computer architecture teaching. In the current research, we extend the previous approach to generating questions with multiple variables on Directed Acyclic Graph (DAG) knowledge structures. Questions generated with the new algorithm are more complex and require more mathematical skills to solve. The algorithms can be applied to any discipline for which the conceptual and analytical knowledge can be represented by a DAG.
