During recent years, a growing shortage of skilled professionals in the area of Information and Communication Technologies has been seen. This is compounded by a lack of general awareness regarding the role of the professionals in this area of our society. The rise in recent years in the use of mobile devices translates into an opportunity to help solve the problems mentioned above. This paper presents the design, structure, execution and results of a mobile applications development workshop that also aims to increase the interest of secondary education students in following a Software Engineering career. The design of the workshop is discussed in terms of constructivist learning foundation concepts, and the selection of tools is presented following key features for supporting the designed activities. The results obtained show that the workshop had a positive impact on the perception of Software Engineering as a possible field of education in the 60 students that participated during the implementation of the workshop. It also explores gender differences in terms of areas of interest for the development of mobile solutions, programming performance and preferred development activities.
