Virtually learning outside isn’t going to be very easy. Quarantine has made going outside restricted in some parts of the world. If a teacher doesn’t have a backyard, they won’t be able to go outside and teach. It makes learning outside literally impractical.
If teachers were to offer alternative learning materials for learning about nature, it would only encourage students to stay indoors even more. Learning about nature in a book or a computer screen doesn’t not have the same stimuli as if an individual interacted with nature.
The more students that learn about nature and the environment in this way will become detrimental to future students. They won’t be encouraged to learn outside.
If quarantine is still in place, there will be a boundary for truly learning outside. Teaching students via books and videos is what people are concerned with already. It defeats the purpose of keeping students excited and motivated about learning outside. There needs to be an alternative solution, otherwise future outside classes will diminish.
