Language Acquisition and Learning

There are two ways we can get better in a language; learning and acquiring says Dr. Krashen. This is a very important concept to understand. There is a key distinction between the two. Copied the text from Dr. Krashen's book.

Should we help our children learn a language or acquire a language. Please read.

The first hypothesis in his Natural Approach is about the acquisition-learning distinction. The acquisition-learning distinction is perhaps the most fundamental of all the hypotheses to be presented here. It states that adults have two distinct and independent ways of developing competence in a second language.

The first way is language acquisition, a process similar, if not identical, to the way children develop ability in their first language. Language acquisition is a subconscious process; language acquirers are not usually aware of the fact that they are acquiring language, but are only aware of the fact that they are using the language for communication. The result of language acquisition, acquired competence, is also subconscious. We are generally not consciously aware of the rules of the languages we have acquired. Instead, we have a "feel" for correctness. Grammatical sentences "sound" right, or "feel" right, and errors feel wrong, even if we do not consciously know what rule was violated. Other ways of describing acquisition include implicit learning, informal learning, and natural learning. In non-technical language, acquisition is "picking-up" a language.

The second way to develop competence in a second language is by language learning. We will use the term "learning" henceforth to refer to conscious knowledge of a second language, knowing the rules, being aware of them, and being able to talk about them. In non-technical terms, learning is "knowing about" a language, known to most people as "grammar", or "rules". Some synonyms include formal knowledge of a language, or explicit learning.

Some second language theorists have assumed that children acquire, while adults can only learn. The acquisition-learning hypothesis claims, however, that adults also acquire, that the ability to "pick-up" languages does not disappear. This does not mean that adults will always be able to achieve native-like levels in a second language. It does mean that adults can access the same natural "language acquisition device" that children use. As we shall see later, acquisition is a very powerful process in the adult.

Error correction has little or no effect on subconscious acquisition, but is thought to be useful for conscious learning. Error correction supposedly helps the learner to induce or "figure out" the right form of a rule. If, for example, a student of English as a second language says "I goes to school every day", and the teacher corrects him or her by repeating the utterance correctly, the learner is supposed to realize that the /s/ ending goes with the third person and not the first person, and alter his or her conscious mental representation of the rule. This appears reasonable, but it is not clear whether error correction has this impact in actual practice. Evidence from child language acquisition confirms that error correction does not influence acquisition to any great extent. Brown and his colleagues have shown that parents actually correct only a small portion of the child's language (occasional pronunciation problems, certain verbs, and dirty words!). They conclude from their research that parents attend far more to the truth value of what the child is saying rather than to the form.

For example, Brown, Cazden, and Bellugi report that a sentence such as: Her curl my hair "was approved, because the mother was, in fact, curling Eve's hair". On the other hand, Walt Disney comes on on Tuesday was corrected, despite its syntactic correctness, since Walt Disney actually came on television on Wednesday. Brown et al. conclude that it seems to be "truth value rather than syntactic well-formedness that chiefly governs explicit verbal reinforcement by parents--which renders mildly paradoxical the fact that the usual product of such a training schedule is an adult whose speech is highly grammatical but not notably truthful".

The acquisition-learning distinction may not be unique to second language acquisition. We certainly "learn" small parts of our first language in school (e.g. for most people, the who/ whom distinction), and similar distinctions have been made in other domains.


Ease of master Tamil, developing competence, and long term retention are important for us. So, let us help our children acquire Tamil rather than learn it. I suggest we structure our curriculum, lesson plan, and class activities to help them acquire Tamil.

Language Acquisition Resources

It is important to understand how the brain acquires a language and how we develop competency in language. We can then develop language teaching approaches based on this information. We need the tried and proven concepts, theories, and approaches to effectively take Tamil to our next generation. This knowledge and our practice using these approaches will help us become better language teachers and educators.

The following are valuable resources to learn about language development, language acquisition theories, and language teaching methods.Some of these books also provide a lesson plans to teach a language to beginner like most our students are.

Language Acquisition:























Notes from the book Fluency Through TPR Storytelling - Dr. Blaine Ray.


Keys to fluency

Children acquire languages in a context. So, teach vocabulary in meaningful and interesting contexts.
Teach them in ways
  • they can understand in the beginning.
  • retrieve and use it in speech and writing later.

The key elements to Language teaching using TPRS


Key element 1

Help the learners acquire words thoroughly.

Accept silent period. During this silent period, do not expect or force output. Forcing early production puts pressure on the kids.

Pre teach words. Before discussing the words in a class, set the stage pre teaching the words so the class will be fully comprehensible.

Make everything comprehensible

Model the word using TPR.

Check for comprehension regularly, especially the slow students

Quantity and technique are important.

Make it highly believable; make them feel it is real. They should not feel the stress of being in a different language environment.

Comprehensible Input and High believability produces long term memory.

TPRS activates kinesthetic sensory systems; muscle learning.

Teach to the right side of the brain.

4 groups of items
  • TPR words
  • TPRS words
  • Cognates, a word that means the same in both languages.
  • Special words list

Key element 2

After the words have been acquired from step 1, the learners must put them into fuller meaningful and interesting contexts.

Use events from students own lives
  • ask questions utilizing new words to inquire about their own experiences.
  • use mini-stories and mini-situations

Key element 3

We need a vehicle for the learners to practice the vocabulary in a speech. Repeating memorized lines does not help language acquisition. They need a way to express themselves in their words using the vocabulary they built so far. Use storytelling as a vehicle to practice the words acquired.

Key element 4

Make the class fully comprehensible.

Key element 5

Conduct class in target language at least 90% of the time.

Key element 6

Make the stress as low as possible. A stressful mind blocks all the input.

Krashen: A language can be acquired well in a low anxiety environment.

Key element 7

Have high expectation of the class result. Everyone gains fluency.

It is not enough if you cover the syllabus. It is not enough if only the bright students mastered the materials. Have an expectation that at least 90% of your class understands at least 90% of the words you taught. When you make the students who have not learned something repeat and redo a lesson you are communicating that everyone’s mastery is important.
