In this paper, an interactive environment for learning by problem-posing targeting arithmetic word problems that are solved by one-step multiplication is described. Its practical use in an elementary school is also reported. We had already developed an interactive environment for learning by posing arithmetic word problems that can be solved by one-step addition or subtraction. Then, a practical use by the first grade students of an elementary school had been performed. The results suggested that the learning by using the environment was effective to improve the student's problem solving performance. As the next step of this previous research, we have developed another learning environment where a learner poses the multiplication word problems. In order to design the environment, we categorize word problems that can be solved by one-step multiplication based on the sorts of quantities consisting of the multiplication. Then, based on the categorization, we have built a task model of the problem-posing. The learning environment is used by a class of the second grade students for 9 class times, and we have confirmed that the scores of problem-posing and problem-solving were improved in the group of students who obtained low scores in the pre-test.
