The pandemic It caused universities to teach their classes virtually, that is, through video calls made by Google Meet Zoom Microsoft Teams, among other platforms that are characterized by being easy to use and because they allow interaction between the teacher and the students .
Although this global problem is not over yet, blended classes are about to become a reality. In 2022, there will be certain courses in which the student will have to physically attend a university classroom, while others can continue to be taken remotely.
Although this type of blendedness will be the most common in universities, there is a hybrid model that allows the same class to be taught both to students who are in the classroom and to students who are connected from their homes.
Juan Pablo Romero, Lumen unified communications manager, spoke with The Republic to talk about two technological solutions that will be very helpful for those universities that plan to provide this type of teaching.
According to the specialist, these tools called “video collaboration” and “collaborative whiteboards”They use the artificial intelligence to eliminate the image of the teacher and in this way the students (who receive classes from home) can see the blackboard clearly.
“Hybrid classes need the blackboard to be correctly visualized both by students who are physically in the classroom and by those who are remotely. If the teacher is in front of the blackboard, artificial intelligence will make it transparent so that the notes can be seen ”, he said.
It is worth noting that the students who are remotely would not need any virtual reality viewer or other expensive device to benefit from these solutions, it is enough to have a device with internet connectivity, it can be a laptop, tablet, computer, etc.
One of the great difficulties of hybrid classes is the noise of the environment; However, the solution developed by Lumen has a microphone system that reduces ambient noise, since they only capture the human voice.
According to the expert, many universities do not opt for hybrid classes because they do not have the budget to hire a technological solution; however, it highlights that the prices to implement these hybrid classrooms are no longer as expensive as before.
Another reason that hinders its implementation is that it involves a great challenge for teachers who should not only be concerned with the students who are in front of him, but also with those who are from their homes.
“The didactics changes drastically. It is one thing to keep a group of people who are locally interested and involved in a class and another thing is to keep a student who is watching from a distance internalized and trapped while doing the same thing, ”he explained.
Among the advantages of a hybrid class is the breakdown of geographic barriers in education, since one could take courses in the university one prefers, without worrying if he is away from home or not.
“The geographical barriers are much lower and the offer of the universities now has to be more attractive, because the audience they can capture is much larger than before,” Romero said.
