Redefinition of Arithmetical Word Problems in order to Change from ``Problem Solving'' to ``Problem Comprehension'' and Role of Problem-Posing as ``Objective Action''

Abstract

We have already developed several interactive environments for learning by problem-posing in arithmetical word problems and use them practically in several elementary schools. Currently, we have formalized this learning activity as "objective action" as a step to promote a learner to externalize a target model. In this paper, we have also explained triplet structure model of arithmetical word problem as the target model.
