Evolution of virtual teaching

If you're interested in a timeline of the relationship between e-learning and education, and how technology led to virtual education, here it is.

Characteristics of education

virtual and face-to-face

Characteristics of the virtual and classic models

A common but not always well understood characteristic is a contrast between the virtual and the real. This opposition does not allow for you to deeply think about virtual teaching. Virtual learning is still real because it uses the Internet or online media as a form of presence. In fact, the virtual represents the gateway to a more accentuated wealth in Distance Education (EAD).

Before virtual education, there was already distance education, for example, in the country, where people were educated via educational programs and materials, listening to classes on the radio and attending some meetings sometimes weekly, monthly or quarterly in accordance with the program.

Methodologiesused

In virtual teaching

When we talk about methodologies we mean the "how" of teaching and this means that we think about how a person learns or, rather, the forms, and also the ways of teaching. This reflection is known as didactics and we have many examples, such as constructivist didactics that will emphasize peer learning and social environment and behavioral didactics that will emphasize the study of students' responses to different stimuli. These are just two examples, but there are different types of didactics. In the case of virtual teaching, learning and teaching also have their particularities.

For virtualteachers:

A tip for online teachers is to take care of specific aspects that we mention and not to try to transpose or transfer the same practices from the classical teaching model, sometimes called the old teaching model, to the virtual teaching model.

Virtual teaching assumes what some call maturity.

That is, the dedication you must have, to do the readings, reflections...

And for students, in addition to the responsibility of virtual learning, participation and interaction with teachers and other students will always be productive, because it will give you an idea of how things are going. from what people think and it will enrich the way you approach the topic you are studying and learning.

Myths related

to virtual teaching

Myths about virtual teaching

Myths are ways of understanding reality and are based on culture, feelings, prejudices, concepts, ideas, relationships, but that often do not take into account some facts and data that could enrich what they propose. Myths can be positive, when used to convey ideas and teachings. For example, many cultures have myths to explain how we understand ourselves as human beings.

Some are more famous than others, such as Greek myths, the creation myths of the world. The problem with myths is when they don't let us see beyond them. For example, suppose the myth that heavy objects fall faster than light objects remained true. Galileo would never have discovered the importance of gravity, and we would not be flying from one place to another so easily.

There are professions that cannot be learned virtually

You can't learn without contact with a teacher

Virtual teaching is going to end real teaching

This refers to professions such as medicine, advocacy, aviation or engineering. Nothing is further from the truth, because virtual teaching allows pilots to do flight practices without flying, doctors can do virtual surgeries and have a more complete view of some virtual reconstructed organs, which otherwise would be impossible. The problem with this myth is that there are careers that warrant supervised knowledge and practice. But virtual teaching was not made to end that dynamic, but to bring it greater resources.

First, learning is not defined by just one person. It’s not only teachers, but also classmates, environment, materials, and content that play a key role in the learning process, exercises, and complementary activities.Speaking about the teacher, contact with this figure is not missing in virtual teaching. It is redefined through the spaces that the platform, teachers and students, define as contact.

By real teaching, many people are referring to traditional teaching. Care must be taken with the myths that are based on the nostalgia of the past. Using them, many people claim that in the past everything was better. The important thing is to be able to think that virtual teaching, through technology, came to enrich the new educational models and make knowledge an educational experience.

Uses of virtual teaching

The statistics show not only the current status of virtual education, but also its trends for the coming years. In fact, the total number of students in contact with virtual education is expected to be nearly $70 billion, more than three times the gross domestic product of the entire European Union.

A trend that emerges from the academic curriculum curve is the growing movement of free online course offerings. This type of course offers rich knowledge, the only difference is that some do not offer university-recognized certificates. Here you can see the best selling niches of online courses:
