Sometimes you can learn more outside the class than you can inside. I agree with this statement because we spend more time outside the class. We can learn more when we deal with different people further when we read online literature, beside that when we live in same culture like in well-educated neighborhood.
First, if we share our ideas with another person then we collect information from him. It means that we are learning something. Traveling around can also help us to see the different billboards and we can get a lot of information. To deal with the customers can help us to improve our communication skills
For example: My friend is working at store where he can communicate with different customers so he would have easy ways to learn and he personally gets a lot of improvement now he has better communication skills.
Second, if we read online books or Newspapers then we can improve our vocabulary also we can get different information. When we watch television it can help us to improve pronunciation, gestures and postures.
For example: My uncle always said that there are three ways to improve communication reading, writing and hearing. Television is best source for entertainment and learning.
Third, Culture plays very important role in learning. If you are living in a same culture where you can talk with people who can speak with you in same language which you want to learn. It can help you to improve it.
For example: One of my friend came to this country after I came here but he can speak better then I speak English. He lives in English speaking neighborhood and I live in another neighborhood.
In conclusion, you can learn more outside then you learnt in class but if you deal with different people, try to read as much as you can and stay in same culture where you can learn.
