The main objective is to know the level of influence of the factors that make up the Constructivist On-Line Learning Environment Survey (COLLES) questionnaire, on affective support, mediated through the LMS Blackboard Learn, in engineering students at the level of undergraduate degree at a private university in Peru in times of Covid-19, using the PLS-SEM methodology, which is a multivariate method called Modeling of Structural Equations with Partial Least Squares. The results obtained from the exploratory and confirmatory factorial analysis, has allowed to corroborate that the most important factor in collaboration as a basis for meaningful learning is affective support, in which affective/cognitive mediations are established between students.
