This review introduces a series of researches of interactive learning environments for arithmetic based on analysis of learning content as a promising approach to realize advance learning and teaching activities on ICT infrastructure. In the content analysis, problems used in exercises are analyzed and modeled them with structural representation. Then, learning and teaching activities are designed based on the modeled problems. In this review, as concrete researches, structurization of calculation problems of fraction in order to diagnose erroneous answers is described as the first one. Then, a framework of structurization of arithmetical word problems and a function of problem explanation are reported. Moreover, several systems of problem-authoring and learning by problem-posing designed based on the framework are introduced.
