Editorial In recent times, we have been seeing a deepening relationship between humans and technology, in particular, digital technologies. According to Don Ihde, one of the most prominent contemporary philosophers of technology, the use of technology is not impartial and it is always transforming human experiences, changing the way we try to understand the world and ourselves. Thus, exposure to new technologies provides not only more possibilities of acquiring information but allows us to
... t allows us to experience a multiplicity of perspectives. A better understanding of modern science requires us to reflect upon these relationships and assume a more critical posture. One aspect of the relationship between people and technology is the creation of a new environment, whose elaboration simultaneously generates experiences. A second aspect involves a relationship mediated by devices, suggesting alterity. A third part involves the body through an interaction that makes possible a unique representation of the world. A final aspect incorporates tools, which permit an extension of perception. The first paper in this issue proposes an alternative way to compensate for the lack of laboratories in science education, using video analyses as a teaching resource, enhancing the opportunities of learning, as well as fostering better uses of tools, aiming to deepen students' comprehension of reality. In the same line, the second paper helps students to develop reasoning ability through an interactive method applied to the solution of biology problems involving graphics. The next paper presents a socio-historical analysis of public policy implementation by the education ministry known as School Development Plan (PDE Escola), mediated by Digital Information and Communication Technologies (ICDT). This study aims to improve understanding of the expansion and consolidation of this educational policy based on advances of ICDT in the education process. The fourth paper presents a method to teach finances to deaf young people and adults who communicate in Brazilian sign language, through the perspective of ethnomathematics and the concept of technoracy (the use of material and technological tools), in problem situations proposed in the classroom. The fifth paper proposes how to distribute income tax more fairly among contributors. The idea is to replace the current stratified model by a continuous one, in which small changes in income are considered in the final calculation. The final paper tackles the great demand for storage by organizations, which, in addition to expansion of capacity, equally requires increased security, availability, reliability, and diversification of accessibility. The proposed solution relies on finding a good cost-benefit ratio when extending the life of hardware devices while trying to reach higher levels of quality and security. According to Ihde, other dimensions used to interpret reality remain undetermined: many perceptions in a given moment, stable despite their various forms; rich context in artifacts and meanings or identities, no less useful or interesting. We invite you to join us in reflecting on this curious diversity.
