As all resources, Internet is useful for teachers, in our case for English as second language teachers. Intenet is useful and, at the same time, it’s dangerous for teachers and pupils.
It’s dangerous for teacher because they could become easygoing. That is, they can search a lesson, or a topic or something like this, and never come to think something to solve their classroom troubles. You can look for solutions to a concrete trouble of a certain child in one of your classes, but not repeat classes that you find in Internet.
Besides this, Internet is dangerous for children because they could find inappropriate things, as adult content, games…, or simply they can get confused the publicity of the webs.
If, as I hope and think, teachers are careful, Internet is the best resource for our job. We can find a lot of activities, examples, lessons, methodologies, and even personal experiences of others teachers which could be interesting for our own improvement. besides this we can make our own webs, blogs, activities, songs, videos, and things like this to improve our classes, making them more allure, motivating and interesting for our pupils.
In summary, we have in Internet the most valuable tool to improve the learning of our pupils.
