4.2 Theory of Second Language
Acquisition
Humans acquire language in only one way - by
understanding messages or by receiving
‘comprehensible input’ (Krashen, 1985). Speaking
is a result of acquisition and not its cause.
Speech cannot be taught directly but ‘emerges’ on
its own as a result of building competence via
comprehensible input. If input is understood, and
there is enough of it, the necessary grammar is
automatically produced (Krashen, 1985). Although
comprehensible input is necessary for acquisition, it
is not sufficient. The ‘affective filter’ is a mental
block that prevents acquirers from fully utilizing
that comprehensible input they receive for language
acquisition. When the acquirer is anxious,
unmotivated or unconfident in the process of
receiving a message, he or she may understand what
he hears and reads, but the input will not reach the
LAD (Chomsky’s Language Acquisition Device:
LAD). When this happens, we say the filter is up.
And the filter is down when the acquirer is not
concerned with the possibility of failure in language
acquisition and when he considers himself to be a
potential member of the group speaking the target
language. The filter is lowest when the acquirer is
more involved in the message (Krashen, 1985). We
can summarize that comprehensible input and a low
affective filter are two important factors
encouraging second-language acquisition (Krashen,
1985). Using interactive whiteboards can help
students achieve comprehensible input and a lower
affective filter. Firstly, when using interactive
whiteboards in teaching, the teacher can use videos,
pictures, images, and animation, which are built-in
or stored in interactive whiteboards, to help students
understand knowledge. Sometimes knowledge and
ideas are abstract and complicated so that it is not
easy for students to understand without the help of
these aids. In other words, these technological aids
make input more comprehensible. Additionally,
with the help of an interactive whiteboard, the
teacher can integrate words, pictures, images, videos,
audio, animations, etc., into the teaching material,
presenting teaching content in a vivid way, and
students can also physically manipulate the texts on
the whiteboard, making learning more enjoyable,
thus reducing the anxiety and enhancing students’
motivation for learning.
5 APPLICATIONS OF
INTERACTIVE
WHITEBOARDS IN EFL
EDUCATION
A noteworthy number of studies have accredited that
interactive whiteboards can improve the outcomes of
English education. In an article by Zezulková (2017),
the interactive whiteboard was used to teach English
lessons. The subjects were 11 to 15-year-old students.
In the study, the teacher designed speaking,
vocabulary, grammar, writing, reading and listening
activities with the help of an interactive whiteboard.
For example, for developing students’ speaking skills,
the teacher created an activity called “one story”.
Firstly, the teacher presented an image on the board
and then told the students to tell a story. The first
student would initiate the story and stop in the middle
of a sentence. Then the second student continued the
story. Like the first student, the second student also
stopped in the middle of a sentence. And the rest of
the student followed the same pattern until the teacher
told them to finish it. For vocabulary learning, the
teacher created an activity called “one body” in which
the teacher presented a person’s silhouette and icon
(speakers) on the interactive whiteboard. By clicking
on the icons, the students can listen to the words about
body parts. The students can come to the whiteboard
and drag the body parts to the right place on the
silhouette. Grammar learning is not infrequently
unpopular with students. Interactive whiteboards can
make grammar learning more interesting. In the
research, the teacher used the “word order” activity to
teach grammar, in which a few sentences were
divided into single words and can be dragged on the
screen. The students were invited to come to the
whiteboard to put the words in the right order.
The writing activity in the study was similar to the
aforementioned speaking activity. In the writing
activity, the students were told to write a short story
together. The teacher prepared a blank page on the
whiteboard and the first student was asked to come to
the front to write one sentence but stop in the middle
of the sentence. The second student would finish the
partial sentence and start a new one, and the rest of
the students followed this pattern until it was finished.
In the listening activity, students were required to
listen to some people talking and drew what the
people had been talking about. Likewise, the students
were asked to come to the front to draw something
which can be drawn simply, such as a house, the sun,
a car, etc., according to what they hear. The recording
can be replayed if necessary, and the pictures can be
