Grammar correction harms language acquisition
The standard way foreign languages are taught still involves very little speaking practice, rather a lot of translations from ones native to the target language and lots of grammar drill, outdated methods that do more harm than good.
The problem with this: it is not only about the most ineffective way of language training, some of these elements such as translations and grammar drill are outright harmful.
Before we get into the details, please consider this: how did you learn to walk? All by yourself I believe and further you might agree that nowhere in the world there is a pediatrician or pedagogue who would advocate special walking instructions and drills for babies and toddlers (unless they were disabled). Likewise we all know that children learn their native language automatically just by listening and gradually communicating with people who are more advanced than they. By the age of six a normally developped child knows about 100,000 words in their native language if you count all word forms, e.g. go -> went, brother -> brethren, may -> might etc. Even a professor who later teaches that language as his best foreign language will hardly ever surpass such a six year old which you can easily check by asking him or her for e.g. a list of thirty types of tree or thirty species of birds, or if he knows the games and toys such child usually plays with in his native language and is accustomed to name.
So we may safely say that natures normal way of acquiring a language is the best, simply the most effective way and that all other methods lag miles behind. Now there are a lot of rather good and fun ways to learn a language even if theyre still not as effective as the simple way babies acquire their first. But there are certain widely employed methods that are outrright harmful and one of them is grammar training.
Did you ever reflect on grammar when acquiring or using your native language until the age of six? Not really, most people whose parents are accomplished speakers just pick up their parents style and vocabulary. The most important thing though is that we have certain areas in our brains that are trained to distill rules from repeating patterns, such as past tense or the plural "s" as in manner -> manners, fan -> fans, can - cans etc. This process is automatical and the correct "grammatical" rule becomes woven into the language usage pattern and then works without thinking.
But if you force anyone, esp. children, to reflect upon those rules, worse even to learn them up front, you will destroy that rule building process with the end result that your child may never learn that second language fluently but may always behave like a self-conscious and slow speaker who tries to first access his/her grammatical "rule book" that is by now saved in a completely different part of their brain.
This is known since decades, however, modern school currikcula and teacher training does not reflect that knowledge. Rather children are given assignments in their native language and challenged to translate into the target foreign language, whereby they are asked to apply those cherished rules. This is part of a series of articles where we will also cover the harm thats done by forcing children to translate early between languages. Lets just quote a few sources on grammar drill and its effects:
"Why Doesnt Grammar Correction Work? The first reason why writing class grammar feedback doesnt work is that it treats only the surface appearance of grammar and not with the way language develops ... Secondly, learning grammar in a second language is a complex and gradual process which occurs both developmentally and hierarchically (some items are acquired before others). Compounding this is the fact that the learning of linguistic items does not occur in a linear fashion, that the learning curve for an item is full of valleys and peaks, progress and regressions." (Grammar Correction in ESL/EFL Writing Classes May Not Be Effective, Ronald Gray, Beijing Language and Culture University (Beijing, China)) http://iteslj.org/Techniques/Gray-WritingCorrection.html The author then continues: "So what should a L2 writing teacher do? The quickest and most effective solution would be for writing instructors to simply stop making grammar corrections." And take note: "In short, teachers need to train themselves to set aside their red pens and examine ideas and see what students are trying to say instead of simply looking for grammatical errors."
"When you are just learning to speak a new language, learning grammar rules is not only senseless, but harmful as far as developing your ability to fluently express yourself. ... In most cases, our speech is formed by communication, the quantity and quality of studied literature, education, or simply our surrounding environment. During systematic simultaneous repetition, one develops an inner sense of the language, and the ability to imitate correct pronunciation of words and phrases."

"Teachers and students who take correction seriously face overwhelming problems, both in making the corrections effective and in dealing with the harmful side effects of the practice. Research evidence points to the conclusion that oral correction does not improve learners ability to speak grammatically. No good reasons have been advanced for maintaining the practice. For these reasons, language teachers should seriously consider the option of abandoning oral grammar correction altogether." (John Truscott: "Whats Wrong with Oral Grammar Correction", http://www.hss.nthu.edu.tw/~fl/faculty/John/What%27s%20Wrong%20with%20Oral%20Grammar%20Correction%201999.htm summed up here also: The Case Against Grammar Correction in L2 Writing Classes, Language Learning 46:2, June 1996, pp. 327-369 http://www.hss.nthu.edu.tw/~fl/faculty/John/Grammar%20Correction%20in%20L2%20Writing%20Class.pdf )
"... comprehensive treatment and overt [grammar] corrections are probably not worth the trouble for teachers to make. ... neither use ... of techniques in correcting student errors has an influence on writing ability results. ... [Also] no evidence of an effect which later shows up. Semke Kepner study reveals that grammar correction to second language writing students is actually discouraging to many students, and even harmful to their writing ability. Generally those who do not receive grammar corrections have a more positive feeling about writing than those who did, wrote more, and with more complexity [!], than those who did receive grammar corrections."

How to emulate the native language/first language acquisition and use it in second language education is currently piloted in a project at Arete schools http://www.fsa-ev.de/ , a small progressive school in Germany,
