AMBRE-add: An ITS to Teach Solving Arithmetic Word Problems
Sandra Nogry, Nathalie Guin and Stephanie Jean-Daubias
This paper describes the design and evaluation of AMBRE-add. This Intelligent Tutoring System (ITS) was designed to teach problem classes and the solving techniques associated to those problem classes in the domain of arithmetic. AMBRE-add uses case-based reasoning as a learning strategy. It presents solved problems in each class to learners, and then guides them to use the case-based reasoning steps to solve new problems. We evaluated this system in the classroom on four classes.
