In this unit, I learned some of the differences between
first language (L1) and second
language (L2) learning. These
differences are classified taking into account the learners ‘age, ways of
learning and the context that they are learning in. First, regarding to
learners´ age. When learning a firs
language, generally we pick it up when we are babies listening to our
parents using the language. It occurs at the same time we develop our cognitive
skills. Then it continues through the years of childhood and improves into
adolescence. On the other hand, when learning a second language, it can start
when we are adults or in primary or secondary school when our cognitive skills are not yet developed.
Second, regarding to context. People
usually learn a first language by lots of exposure and interaction with people
who speak the same language (native speakers) specially their parents. On the
contrary, in a second language learning, learners are often taught grammar with
little exposure to language since it
can only be hear in the classroom which most of times is about 2 hours a
week. Moreover, when learning a first
language there is strong motivation
for doing it because we feel the need to communicate, we can play and
experiment the language. Whereas in a second language our motivation can vary: strong,
little or no motivation because the teacher only uses controlled practice activities and corrects mistakes all time.
Third, regarding to ways of learning. In the first language, learners learn by
talking about things that are presented in their surrounded while second
language learners talk about topics that are mentioned in a book. Furthermore,
first language learners receive a lot of encouragement and praise when using
language which do not always occur with second language learners since some
teachers do not treat all students equally, some of them receive more encouragement and praise than others. I consider
this is important to be aware of because we, as teachers, need to understand
that learning a first language and a second language are two different processes.
When learning a second language we have
to promote exposure because learners need to use language as much as possible
to learn it. What I can do in this situation is to bring to the class authentic
materials such as articles from magazines, movies, songs, etc. Thus, my students
will notice how language is used in real life situations similar to that of
first language. In addition, I can encourage interaction in the class by
promoting group presentations in which learners help each other with language,
it should be done depending on the student learning
style, or designing responsibilities to each student. To sum up, the differences
between learning a first language and a second one has goes from the age, ways
of learning, and the context in which it is learned. The teacher´s task is to
promote activities that are similar to those we acquire learning a first
language.
