It happens in Asia's learning environment, too.
Some teachers focus on
reading and writing abilities, so they explain grammar and analyze them most of the time. Then, kids are good at analyzing grammar and taking paper exams.
However, most of the kids are afraid to speak in English, because they seldom practice speaking in class and after class.
On the contrary, some teachers emphasize the importance of
listening and speaking; therefore, they ask kids to answer one by one in class. Then, kids in this kind of environment are able to communicate with one another.
Yet, most of them lack of accurate grammatical skills when speaking because they lack of grammar training in class.
Except the aforementioned, som teachers focus on 4 areas--
listening, speaking, reading, and writing. So, their lesson plans divide into 4 parts.
Teachers speak whole English in class to train students' listening. Also, asking kids to answer in English in class.
When teaching grammar, teachers either use their mother tongue or speak in English to explain grammar. Then, after a while, they ask kids to write simple sentences to express their ideas.
In my opinion, I prefer the third method. I was once the victim of the first approach. My teachers in high schools focused on drill practices on grammar rules and only spoke in mother tongue in class, so I just knew how to read and write in English for paper exams, but I couldn't listen and speak in English.
Later, when I went to college, my instructors all spoke in English, so I had a hard time to comprehend what they said in class, but in paper exams, I got high scores. So, I recorded instructors' lectures, and listened to them repeatedly day after day. The process was tough, but after a year, I acquired English comprehension ability.
As for speaking ability, I tried to
read articles loudly at home for many times to train my speaking ability. Also, I started to listen to English teaching CDs, and I played one track over and over until I undertood its meaning, and later I tried to do
shadowing, mimic speakers' speaking at the same time.
To sum up, teachers' teaching methods will influence students' learning effects; therefore, teachers should have thorough lesson plans for students.
Also, the best way to learn a language is to listen and speak in the beginning, but read and write later.
BTW, how do we learn our mother tongue? When we were babies, we just listened to what people talked to us, and then one day, we learnt how to talk. Did our parents tell us grammar rules? No.
But, English is a second language. In order to speed learning pace, teachers not only need to focus their teaching on
conversation skills in class, but also ned to spend time emphasizing
grammar rules, too.
