This chapter focuses on the complexity of STEM education, especially for engineering courses, considering the present and future role of these professionals in society. The high specialization of technologies has required vertical education in engineering topics, while the role of engineers of the future will be broader to solve societal problems at a global level. The ability to fill this role can be improved by stimulating the education of engineers with humanistic and social topics, multicultural teamwork and preparation to stimulate creativity and innovation within a laboratory community. In this path we find the relevance of Adriano Olivetti training process. This chapter reports some experiences of innovative teaching that can be useful for the design of university teaching courses in STEM subjects
