In Argentina, during the last 15 years, a process of diminishing enrolment at high-school was registered, while high-school drop-out increased, especially within low socioeconomic groups. Facing this educational reality, some teachers of the School of Engineering at the University of Buenos Aires have started a project whose aim is to raise the level of expectations of children and young adults who are at educational risk, so that they stay in school and have access to an education that allows them to be members of the world of knowledge and work. This project, which received a University of Buenos Aires “Social Emergency” 2004 grant and a YPF Foundation “Strategies for school retention” 2004 grant, offers students of an inner city high-school the possibility to participate, coached and advised by the professors of the School of Engineering, in technological projects involving solutions to actual problems, and then transfer their experience to elementary-school students, working with them within the technological K-8 area. An important goal of this project is to analyze the impact that these technological activities have on these students’ level of expectations. Our hypothesis is that through participation in these technological projects we will be able to: 1) diminish school drop-out in the population at educational risk. Promote the acquisition of technological competence by children and young adults; 2) raise the level of expectations of children and young adults belonging to low socioeconomic groups; 3) integrate the work of researchers, teachers, and students to solve real problems involving technical, methodological, organizational, conceptual, social and ethical aspects
