The health context related to the COVID-19 virus has posed challenges for various areas, in particular, one of the areas with the greatest impact has been education. The research project called DIFPRORET has addressed the analysis of the advantages and disadvantages that the impact of this virus has had on the educational world. The objective of this article is to analyze the perception of 112 subjects about the use of digital platforms through three questions: the educational difficulties encountered in the period of confinement, the main challenges that we must overcome to address education in periods of confinement and which would be the most relevant proposals for improvement in these circumstances. The methodology was approached from the multivariate analysis: multidimensional scaling and hierarchical clusters. It was observed that two of the main educational difficulties are the organization of time and the preparation of activities in contexts of confinement. In this sense, the proposals point to different levels: the improvement of individual student-teacher competences, access to computer resources and investment to alleviate social inequality.
