DIANE, a diagnosis system for arithmetical problem solving

摘要: We hereby describe DIANE an environment that aims at performing automatic diagnosis on arithmetic problems depending the productions of learners. This work relies results from cognitive psychology studies insist fact problem solving depends to a great extent construction adequate representation problem, which is highly constrained. allows large-scale experimentations and has specificity providing very detailed level precision, whether it concerns or erroneous strategies, allowing one analyze mechanisms involved in process. The quality module been assessed and, concerning non verbal cues, 93.4% protocols were diagnosed same way as with manual analysis.
