This document presents the validation of a survey to contrast pre-pandemic online and face-to-face education. Beginning with the evaluation of the judgment of experts and teachers for preparation and proposal, which according to the methodology, was administered for a self-evaluation of university students in three areas of knowledge, and consisting of four different dimensions: attitudes during the Covid19 pandemic, applications of ICTs in education, problems when studying online, and exploration of face-to-face education The results show that it is a valid and reliable instrument to measure the four aspects described.

With the goal of know and evaluate the face-to-face education previous to the pandemic and contrasting it with the education accomplished during the COVID 19 pandemic, this research was carried out on undergraduate students. A survey was applied, previously validated (Ortiz-Sánchez et al., 2021), the results allow to know aspects related to ideas that students have expressed during the exercise of online classes and in pre-pandemic. The research was carried out with students of different levels and areas of academic preparation.
