In this paper, we described about a design of learning environment based on information structure and a realization of problem posing for learning disability. We design and developed software by modeling information structure of subject that is operated on software. In this research, we aimed at the domain of education and developed a learning environment for posing arithmetic word problem. Problem posing is well-known as effective learning. But students who have learning disability are impossible to learn by this exercise because they cannot pose the problem from scratch and cannot read complex sentence. However, learner is able to pose a word problem by selecting three cards in our software. So we assumed that these learners are able to learn by problem posing by using our learning environment. Experimental use is also reported.
