Diagrammatic Student Models: Modeling Student Drawing Performance with Deep Learning [chapter]

Andy Smith, Wookhee Min, Bradford W. Mott, James C. Lester
2015 Lecture Notes in Computer Science  
To this end, we introduce diagrammatic student models, which reason about students' drawing trajectories to generate a series of predictions about their conceptual knowledge based on their evolving sketches  ...  The diagrammatic student modeling framework utilizes deep learning, a family of machine learning methods based on a deep neural network architecture, to reason about sequences of student drawing actions  ...  The authors thank our colleagues from the LEONARDO project for their contributions to the LEONARDO project: Eric Wiebe, Courtney Behrle, Mike Carter, Angela Shelton, Samuel Leeman-Munk, and Robert Taylor  ...
