The continuous technological development nowadays acts ancillary and supportively in student-centered learning, in both formal and informal education settings. Effective learning environments, such as the AppInventor software, could spark the students' interest and allow them to develop programming skills and strengthen their algorithmic capabilities. In this paper, we present a study on the use of eight educational scenarios for the use of the AppInventor software into a secondary education lesson's context. These scenarios were initially evaluated by secondary education informatics teachers. After that, they were implemented in two public Lyceums in Greece gathering teachers' and students' opinions. The results were very positive for the use of AppInventor during the teaching and learning process through the structured educational scenarios that were provided. According to the students' and teachers' opinions the content of these educational scenarios is presented with clarity and helps in learning the lesson's content without being related with any previous knowledge of programming languages or environments.
