The covid-19 pandemic forced education to seek new ways of teaching and learning In particular, due to the fact that experimental sciences such as chemistry require training in the laboratory and that attendance at these training spaces was interrupted by social isolation, the need arose to investigate new ways of acquiring procedural skills. The objective of this work was to estimate the usefulness of a didactic material, a computerized practice, in the academic achievement of students through the analysis of the experimental performance obtained before and during the use of the computerized practice. It was observed that the students who had the didactic material at their disposal improved their performance, measured by the Hake index. For this reason, it is estimated that computerized practice is useful to improve academic performance in the practice laboratory.
