We all know that there are 4 language skills ( listening ,speaking , reading ,writing ) As TEACHERS and STUDENTS,What is the skill that can help all the other three to be developed?
I believe that reading is the most useful language skill. Reading is a complex cognitive process of decoding symbols in order to construct meaning. Once a person is able to interpret and construct the meaning of the many pieces of literature in the world, they are knowledgeable and able to understand many important aspects of communication.
Reading. Good readers are generally better writers and good readers acquire a much stronger speaking vocabulary. All of the skills you mention are important--and I would argue the most important--for every other kind of thinking and studying, and reading is the cornerstone.
On the other hand, writing is thinking at a much higher level. It's the thought process honed and crafted and filtered. One can be a good reader and not be a good writer, but in my experience you cannot be a good writer and not a good reader. Consequently it seems as if writing would come first and reading second.
I would tend to agree that reading is the most important of the four. Once you learn to read it makes it much easier to learn writing and to speak. I think listening is independent of the other skills, yiu can learn to listen without being a reader. I have seen many students with poor reading comprehension but great listening comprehension.
In my opinion, it is reading. I think that reading can help a person develop the other three (with the possible exception of listening).
When a person reads a lot, they learn how to deal with long, complex sentences that are put together into coherent paragraphs (in nonfiction). They learn different ways of presenting dialogue and narrative(fiction). Both of these help them to be better writers, but they can also help people to speak more effectively. This is because public, formal speaking is closely related to written language.
I believe that reading is very important as well because I learned French for 8 years, I had a difficult time because my learning style was not that of an auditory learner, but a visual learner. So when I would read passages from French textbooks and news articles in French, the french was right in front of me. I could learn how to speak it and I can point at it. I learned the proper way of conjugating and forming sentences that way as well.
