The learning of mathematics continues to be a problem in Ecuador, this research aims to diagnose mathematical skills in the academic performance of students Básica Media de la Unidad Educativa Fiscomisional “Cinco de Mayo” del Cantón Chone, Provincia de Manabí period 2023-2024. The results of the research carried out by means of a diagnostic test are shown, as a way of contributing to the improvement of the academic performance of the students in the development of mathematical skills. The teaching-learning process presents difficulties that lead to poor academic performance. A categorization of topics on knowledge reached in the block of natural numbers, trigonometry and geometry was developed. The impact of the use of information and communication technologies on the resolution of exercises was measured through a survey of the students of the Sept Year of Basic Media. The qualitative, quantitative, and documentary method was applied, in addition to the inductive and descriptive method. The technique applied was a structured base test where the analysis and interpretation of the results obtained in the students was carried out. The results obtained from the diagnostic test showed weaknesses in the approach and resolution of exercises that affect academic performance, the need to improve this teaching process was observed. -learning through the application of strategies methodologies that allow strengthening this process through the new technologies.
