Recently, numerous researchers have been intensifying their research related to the use of software aimed at the teaching and learning process in different areas of knowledge. In this sense, the aim of this investigation was to promote reflections on the work resulting from research related to the use of educational software for the teaching of Mathematics in High School, published from 2014 to 2020, together with the Scielo database. For the selection of articles, the following descriptors were sought: "Educational Software and Mathematics Teaching" and "High School". It was evidenced through the research analyzed here that the use of educational software can contribute both to the teaching and learning process of Mathematics, mainly, contributing to motivate students and to approach the reality of students by promoting mediation by through technologies in this area of knowledge.

With the aging society, there is an increasing need for services and software focused on older people. Digital games are one option of software to be provided as tools for entertainment, education, and well-being. However, to deliver these benefits, games must be developed according to the needs and preferences of older people. Seeking to improve the process of eliciting preferences from the target public, we applied Repertory Grid Technique (RGT) during the participatory design of a game. RGT is a cognitive interviewing technique based on Personal Construct Psychology, which has applications in different areas, including computer science. Although many articles discuss the application of RGT in the development of systems, we did not find, in the literature, any application of the technique with older people. We developed a game focusing on older people to understand better how such technique could contribute to game development, following action research methodology. We carried out three cycles of action research, all of which involved the use of RGT. The results indicate some benefits of using RGT instead of traditional semi-structured interviews. The main contribution of this work is to provide researchers with an initial understanding of the benefits of the application of the Repertory Grid Technique for the interviews with older people and how to use it during a participatory design.
