The difficulties in the design and construction of computational algorithms in students and their effect on poor academic performance originated the research project that led to this article. The objective of this research project was the implementation of a pedagogical strategy supported by the educational software App Inventor for the improvement of computational logic in the implementation of algorithms with the Technician in Systems Analysis and Development students in Tulua, Valle del Cauca. Methodologically, a descriptive quantitative research was developed. Firstly, an initial diagnostic test was applied in order to collect data and perform an analysis; afterwards, work sessions were designed with the support of the software App Inventor, and then, a final test was applied. The results identified a satisfactory contribution to the teaching-learning process of the students, which allowed them to build their own knowledge and achieve significant learning. On the other hand, the performance of the students in the classes showed their interest in learning and critical attitude towards the resolution of the different activities proposed.
