explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency levels).
explain how first language development affects development of English (Transferability Theory- Threshold Hypothesis).

To Think About:
Is it better to learn a second language when one is young or when one is older? Why?
Discuss your ideas with a partner.
![Page 5: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/5.jpg)
The Critical Period Hypothesis (Eric Lenneberg (1967)
Lenneberg stated that:
L2 is best learned between age 2 and puberty
Ability to learn language is negatively affected by the completion of process of lateralization
![Page 6: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/6.jpg)
Critical Period Hypothesis Laterialization is when each side of
the brain develops its own specialized functions
Young learners use the same part of the brain for learning both languages
Older learners use different parts of the brain
![Page 7: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/7.jpg)
Lenneberg stated that Lateralization is completed by puberty Therefore, L2 should be learned between
age 2 and puberty (according to Lenneberg)
More recent research has indicated that lateralization actually is completed by age 5
![Page 8: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/8.jpg)
Therefore, young learners (before age 5) are actually native speakers of both languages
They learn both L1 and L2 the way a native speaker does
![Page 9: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/9.jpg)
Advantages to being a younger learner
More likely to develop a native-like accent
Less to learn to be considered proficient More likely to receive comprehensible
input
![Page 10: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/10.jpg)
Advantages to being an older learner
Can consciously use strategies to aid learning
Has knowledge from L1 to draw from Has greater control over input
![Page 11: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/11.jpg)
Proficiency includes grammatical, sociolinguistic, discourse and strategic competence

If you wanted to learn another language, how long do you think it would take you to speak and understand that language? How long would it take you to read and write?
Discuss your ideas with a partner.

How can you identify a learner’s language acquisition level?
Discuss with a partner how the language acquisition level can be determined. In other words, how do you know if a learner is a beginner, an intermediate, or advanced learner of the L2?
![Page 20: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/20.jpg)
Instead of using beginner, intermediate and advanced, a more specific classification system can be used.
A learner can be at the preproduction, early speech, speech emergence or intermediate fluency stage
![Page 21: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/21.jpg)
1) Preproduction/Comprehension Stage Characteristics
Silent period Can respond non-verbally Will be able to understand more than
they can produce The teacher should NOT force the learner
to talk The teacher should ask the learner to
draw, point, act out, label
![Page 22: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/22.jpg)
2) Early Speech Production Characteristics -Can understand more than can produce
-Can produce one or two words at a time
-Will pick up phrases (He cutted.)- The teacher should ask the learner yes/no questions- The teacher should ask the learner choice questions
(Is this a ___ or a ___?)
![Page 23: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/23.jpg)
3) Speech Emergence Characteristics
-Speaks in phrases-Makes lots of errors-Interlanguage occurs (a mixture of vocabulary and structures from both languages)
- The teacher should ask the learner questions such as What is this? What does ___ do?
![Page 24: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/24.jpg)
4) Intermediate Fluency Characteristics-Appear orally fluent-Errors are same errors native speakers make-Struggle with content area reading and writing.
-The teacher should modify higher level questions. For example, instead of asking a student to compare two items, the teacher should ask the student how two items are the same. Then the teacher should ask how they are different
![Page 25: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/25.jpg)
Look at the next slide which illustrates a Dual Iceberg Representation of first and second language development. What does this illustration mean?
![Page 26: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/26.jpg)

Many skills and concepts are common or interdependent across languages.
A skill or concept learned in one language transfers to another language when the necessary vocabulary is acquired
![Page 28: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/28.jpg)
For example, a learner only learns to read once. If a learner can read, he/she can read in another language, once the vocabulary is learned.
What needs to be explicitly taught in the other language are the features that are different.

Critical and Cultural Literacy(interpretation of text given a specific cultural world view)
From: C. Roberts. (1994). Transferring literacy skills from L1 to L2: From theory to practice. In The Journal of Educational Issues of Language Minority Students, v. p. 209-221
![Page 32: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/32.jpg)
The threshold hypothesis states there is a threshold level of ability that needs to be reached in one language in order for a learner to be successful in another language
The threshold hypothesis also states that high levels of bilingualism have positive cognitive effects
![Page 33: explain expected stages and patterns of language development as related to first and second language acquisition (critical period hypothesis– Proficiency.](https://reader035.fdocuments.us/reader035/viewer/2022062311/5a4d1aed7f8b9ab05997c1b7/html5/thumbnails/33.jpg)
The better developed the L1, the better developed the L2 can be.
High level of proficiency in L1-high level of proficiency in L2 is possible
A low level of proficiency in L1-lower level of proficiency in L2
