The results show us that 73.8% of the students perceive that the virtual classroom improved communication and helped the exchange of information between students and 71.4% indicated that the use of the virtual classroom made them mor...

The objective of this article is to describe the satisfaction of students with the use of technological simulation tools in learning in the automatic process control course, as part of the pedagogical update in the context of dis-tance education. The Academic Satisfaction Scale (ESA) was used as a meas-urement instrument, the reliability of the data was performed through Cronbach's alpha, giving a consistencyvalue of 0.949. When developing the re-search, it was determined that 56.8% of the students are satisfied with the aca-demic experience of their learning using technological simulation tools in the virtual environment. On the other hand, 11.4% of students indicated that the content transmitted in this course does not excite them and they do not feel comfortable, these results will allow generating feedback to the teacher in their pedagogical techniques and teaching methods. Likewise,...

In this context of virtualization, the educational sector has seen the need to make use of technological advances, for this reason it is important to know the perception of students, after having fully adapted distance learning through tools virtual, which have allowed teachers and students to maintain the pedagogical link at a distance, either through the virtual classroom or through the use of simulation software. In this sense, the objective of this article is to identify the perception of teaching through virtual tools in university students and determine its level of effect or relationship in student satisfaction. This research is approached from a qualitative approach using the Likert measurement method and a content analysis methodology using virtual instruments. The results of the study indicate that 92.9% and 89.3% of the students are satisfied, these results focus on the indica...
