If the 20th century was characterized by an accelerated development of science and technology, to the point that it could be said that the Scientific and Technical Revolution was permanent throughout it, the knowledge already accumulated has created the conditions for this process to be even more dynamic in the 21st century. Every day the distance between discoveries and their introduction in practice is shortening, so the use of New Information Technologies in our Basic Secondary Schools, through the application of a set of methodological actions, will contribute to increase the knowledge of Numerical Calculus in 9th grade.To use the New Information Technologies available for the teaching-learning process of Numerical Calculus in Basic Secondary School, due to its importance in the integral development of our students.
