Language Acquisition: An Overview

Wouldn't it be just great if learning a new language were that easy (despite the "yuck" factor)? While we do have some technology that provides translation into a variety of languages, it often fails to translate accurately due to the complexity of language. Effective communication requires so much more than just being able to translate vocabulary words — it requires knowledge of intonation, dialect, and intent, and a nuanced understanding of word use, expression, and a language's cultural context. For example, one online translation application I tried translated "Fall Events" as "fall down events" in Spanish because it didn't know that I was referring to events in autumn.

So, without a babel fish or perfect technology, we are left with the old-fashioned way of learning a new language, which requires time, effort, and patience. How much time, effort, and patience depends a lot on the individual who is learning, as well as the learning environment and situation, but language researchers have developed a general outline of language acquisition that helps explain the process that language learners go through to develop skills in a foreign language. In this article, I will provide an overview to the stages of language acquisition, and offer strategies designed to support ELL instruction at different stages of language acquisition.

Stages of Language Acquisition

Researchers define language acquisition into two categories: first-language acquisition and second-language acquisition. First-language acquisition is a universal process regardless of home language. Babies listen to the sounds around them, begin to imitate them, and eventually start producing words. Second-language acquisition assumes knowledge in a first language and encompasses the process an individual goes through as he or she learns the elements of a new language, such as vocabulary, phonological components, grammatical structures, and writing systems.

The Six Stages of Second-Language Acquisition

How long does it take for a language learner to go through these stages? Just as in any other learning situation, it depends on the individual. One of the major contributors to accelerated second language learning is the strength of first language skills. Language researchers such as Jim Cummins, Catherine Snow, Lily Wong Filmore and Stephen Krashen have studied this topic in a variety of ways for many years. The general consensus is that it takes between five to seven years for an individual to achieve advanced fluency. This generally applies to individuals who have strong first language and literacy skills. If an individual has not fully developed first language and literacy skills, it may take between seven to ten years to reach advanced fluency. It is very important to note that every ELL student comes with his or her own unique language and education background, and this will have an impact on their English learning process.

It is also important to keep in mind that the understood goal for American ELL students is Advanced Fluency, which includes fluency in academic contexts as well as social contexts. Teachers often get frustrated when ELL students appear to be fluent because they have strong social English skills, but then they do not participate well in academic projects and discussions. Teachers who are aware of ELL students' need to develop academic language fluency in English will be much better prepared to assist those students in becoming academically successful.

Instructional Strategies

If you have ELL students in your classroom, it is more than likely there will be students at a variety of stages in the language acquisition process. What can teachers do to differentiate instruction according to language level? Here are some suggestions for appropriate instructional strategies according to stages of language acquisition.

Recommendations

Scaffold instruction so students receive comprehensible input and are able to successfully complete tasks at their level. Instructional scaffolding works just like the scaffolding used in building. It holds you at the level needed until you are ready to take it down. Scaffolding includes asking students questions in formats that give them support in answering, such as yes/no questions, one-word identifications, or short answers. It also means providing the context for learning by having visuals or other hands-on items available to support content learning. Also, when practicing a new academic skill such as skimming, scaffolding involves using well-known material so the students aren't struggling with the information while they are trying to learn a new skill. Scaffolding includes whatever it takes to make the instruction meaningful for the student in order to provide a successful learning experience.

Use cognates to help Spanish speakers learn English and derive meaning from content. The Colorín Colorado website has a helpful list of common cognates in Spanish for teachers to reference. Teachers can explicitly point out cognates for Spanish speaking students so they begin to realize that this is a useful way for them to increase their English vocabulary.

Explicit vocabulary instruction is very important in accelerating ELL students' English language development. Textbooks include lists of new vocabulary words based on grade-level content, but ELL students need further vocabulary instruction. There are many words in a text that may affect the ELL student's comprehension of the text that a teacher may assume he or she knows. It is important for teachers to develop ways to help students identify the words they don't know, as well as strategies for getting their meaning. Of course it is also beneficial if teachers reinforce the language structures or common associations of vocabulary. For example, "squeak" is a sound that often goes with "mouse" or "door" and it may be stated as, "squeak, squeaky, squeaks, or squeaked."

Error correction should be done very intentionally and appropriately according to student language ability, as noted earlier in the article. Students who are just beginning to speak English are already nervous about using their new language skills and constant correction will not improve their ability; it will just make them want to withdraw. I inform students in advance of the type of errors I will correct, such as "missing articles" and "third person agreement," and then those are the only errors I check. In my class, I do not correct the errors; I circle the mistakes and return the paper to the student. They are responsible for correcting the errors and returning the paper to receive more points. Most of the time the students can make the corrections themselves when they see the area I've circled, but if they have difficulty, I guide them as they make the correction. In this way, I feel there is a manageable amount of correction information to work with and the student will actually learn from doing the correction.

Learning another language. If you learn the language(s) your students speak, they will be thrilled to hear you try it with them. I learned how to say "good morning" in Somali and had to practice for an hour before I felt comfortable saying it. When I did I was rewarded with the big grins of students as they entered the room. They were excited to teach me other phrases as well, and we discussed how much English they had learned since they arrived in the country. They were very proud to think of how much progress they'd made.

Seek the experts in your building or district who can offer you guidance on effective instructional strategies for your ELL students. There are many teachers who have taught ELL students in your content area, have taught a certain population of students, or are trained ESL or bilingual teachers who have a lot of advice and support to offer. Don't hesitate to look for support when you are challenged to reach students who are learning English. This can be especially true when you have a "pre-production" or "beginning level" student and you are responsible for grade level content instruction.

You can also search the Colorín Colorado educator information for useful information and resources to assist you in meeting ELL student needs.

ELL teachers encounter students with a variety of backgrounds and abilities, and until the babel fish comes into existence, they will need to have flexibility, creativity and skill in order to help ELL students make meaning from the new language and content they are learning. An understanding of the language acquisition process and levels will help teachers tailor instruction to meet the needs of a diverse group of learners. Students will benefit from everything teachers do to support the development of their language skills while teaching them grade level content. Together teachers and students develop their understanding of each other, the world around them, and the language that connects us all.
