CHAPTER II
THEORETICAL FRAMEWORK
A. Teaching
Teaching cannot be defined apart from instructional process. Teaching
is a process of showing or helping someone to learn how to do something,
giving instructions, guiding in the study of something, providing with
knowledge and causing the learner to know and understand. Teaching also
means transferring knowledge from the teacher to the students. Teaching
helps the learner to acquire knowledge they need.
Teaching is a complex process. It is not only conveying the information
from the source of information to receiver. Brown (2000: 7) defines teaching
is a process of guiding and facilitating learning, enabling the learner to learn,
and also setting the conditions of learning. It means that teacher has to be able
to facilitate the learning process and learners as well as set the conditions for
learning so that good learning result can be achieved. This statement is
supported by Richards (2007: 198) that quality teaching is achieved not only
as a consequence of how well teachers teach but also through creating context
and work environments that can facilitate good teaching. Thus, the teacher
has to choose or select the appropriate methods, techniques, strategies, and
instructional media to deal with their teaching process. Teacher also needs to
be creative in selecting or developing their materials and strategies to teach
students.

On a whole, teaching is not only process of transmitting knowledge
from the source of information to the receiver but also facilitating and
creating good conditions for learning.
B. Classroom Instruction
Teaching is the process of imparting knowledge from the teachers to
the students. Therefore, their ability to impart knowledge to the students gives
significant part contributing to the success of learning. Since they have to
transmit their knowledge, they will do everything they can to make sure that
their lessons are a success.
In classroom, a teacher plays as the manager. As the manager, the most
powerful person in the classroom, teacher has the authority to manage the
interactional process that goes on in the class (Gebhard, 2000: 69). In
managing the classroom, the teacher has to consider some factors that
influence the teaching process. One of those factors is how the teacher gives
instructions.
The way the teacher gives instruction plays an important role in
managing classroom. Harmer (2001: 4) indicates that there are two rules for
giving instruction: they must be kept as simple as possible and they must be
logical. Teacher has to make their instruction clear to the students and at the
same time provide opportunities through the instruction for students to
interact in meaningful ways (Gebhard, 2000: 78). To make it successful,
teacher needs to be able to manage all the things that relate to the
instructional process such as how to start and finish the activities, the needs in
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017

teaching learning process, instructional media that will be used, kind of
instruction will be given, the order for doing activities and also how to
prevent problems that happen in learning process and how to control students.
In managing instruction, one of the most important tasks that teachers
have to do is to organize students to do various activities. Media can be
utilized to facilitate this. The first thing teachers need to do when organizing
something is to get students involved, engaged and ready (Harmer, 2007:
111). In this case, when teachers use media, students are to get involved in
the utilization of it.
In short, it can be concluded that in classroom instruction, a teacher
should be able to manage all things that happen in teaching and learning
process.
C. Media
Media is one of the components that should be involved in teaching and
learning process. The term „media‟ defined as the plural of „medium‟, is the
way of communicating messages, information or ideas. Arsyad (2007: 4)
defines media as the carriers of information. In addition, Wamalwa&
Wamalwa (2014) indicate that media refer to any kind of format used to
convey information or message. Smaldino, Lowther & Russel (2014: 7) assert
that media refer to any kinds of aids that bring information from the source of
information to the receiver.

Based on the description above, it can be concluded that media are
everything that can be used to deliver the message or information to the
receiver.
1. Kinds of Media
Learning and teaching a foreign language needs a lot of patience,
energy, time, creativity and competence. The success of teaching and
learning of foreign language is determined by number of factors such as
the students, the teachers, the methods, material and media or aids used.
Media are very important to help students acquire new concepts
and skills. There are many kinds of media which can be used by the
teachers in teaching learning process. In general, there are three kinds of
media. They are audio, visual, and audio visual media. Audio media are
media that can be listened to, while visual media are media that can be
seen. Media that involve the senses of sight and hearing are named as
audio visual media. Further, Harmer (2007) states that there are several
types of instructional media that can be used by teachers:
a. The students themselves
Students are the subject of learning. The students are the most
useful resources in the classroom (Harmer, 2007: 176). By using the
students themselves, teacher can do many things in the classroom.
Teachers can use the students as resources for explaining and
practicing meaning. Teachers also can get them to write or talk about
things they like or things they have experienced.

b. Realia
One of teaching media which can be used to show something real
is realia. Realia provides real-life object to the classroom. Realia are
probably the oldest form of classroom aids, but their effectiveness in
helping students to connect language to reality cannot be
underestimated (Brown, 2001: 141). Realia is very helpful to teach the
meaning of words or to stimulate students‟ activities. Realia can be
used as starting point to introduce the lesson and/or understanding
concept of the material.
c. Pictures
Pictures or graphic materials refer to non-photographic and two
dimensional materials which is utilized by the teachers to convey
messages to the students. This kind of material includes drawings,
charts, graphs, posters, large wall pictures, photograps or illustration
etc.
Pictures are utilized for several purposes. Harmer (2007) explains
that pictures can be used for multiple ways comprising:
1). Drilling
One of the appropriate use of pictures is for drilling.
Pictures are useful fo drilling grammar items, for cueing
different sentences and practicing vocabularies. Teachers can
use picture of certain object then nominate a student to name
the object and get his response.

2). Understanding
One of the most appropriate uses of picture is to check the
student‟s understanding. This can be done by giving students
some pictures wich best corresponds to the reading text or
listening passage.
3). Ornamenation
This utilization of pictures means that pictures are used in a
coursebook or the others to make it more appealing. This may
give readers an extra visual dimension to what they are read.
4). Prediction
Pictures are useful for getting students to predict what is
coming next in a lesson. The students might look at a picture
and try to guess what it shows. Then they listen to an audio
track or read a text to see if it matches what they predicted on
the basis of the picture. This use of pictures is very powerful
and has the advantage of enganging students in the following
task.
5). Discussion
Pictures can be used for discussion activity in classroom
teaching. Teachers can provide any picture and ask the
students to discuss the questions relate to the pictures.
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
11
d. Cards
Cards can be used by the teacher in their teaching learning process.
Cards in any shapes and size can be used in variety of ways. Cards can
be used in many activities like matching and ordering, selecting and
card games. Below is the explanation of each:
1). Matching and ordering
Cards are especially good for matching questions and their
answers for both pair or group works. We can also use cards to
order words into sentences or to put the lines of a poem in
order. Another way is to arrange cards containing of pieces of
paragraph into good text or passage.
2). Selecting
Cards really work well if students are to speak on the spot
or to use particular words or phrases in a conversation or in a
sentence. Teachers can provide words on separate cards then
ask students to pick up one of the cards. Then, he or she has to
use the word in a sentence. Alternatively, students can choose
three or four cards and then have to incorporate what is on the
cards into a story.
3). Card games
There are many card game possibilties in language
learning. A simple vocabulary game can be played in which
students have cards with pictures on one side and words o the
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
12
other. If they pick the picture side, they have to produce the
word. If they pick the word side, they have to draw it and then
compare it with the original picture.
e. Tape recorder
Students get exposure to spoken language form of variety of
sources. One of them comes from auditory material which can be
listened through tape recorder. This kind of media is common to be
used by teacher to present material in form of recorded material.
f. Course book
Course book is a form of print media. It contains material or verbal
information through print. It can be used as source of exercise and
source of material.
g. Boards
Boards refer to chalkboard/ blackboard and whiteboard. Board is
one of the teachers‟ greatest allies. It gives students added visual input
along with auditory (Brown, 2001: 193). Like pictures, boards also are
used for several purposes. Harmer (2007) describes that teachers can
use boards as notepad, explanation aid, public workbook and game
board, Below is the description of each:
1). Notepad
Teachers frequently write things up on the board as these
come up during a lesson. They might be words that they want
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
13
students to remember or phrases which students have not
understood or seen before.
2). Explanation aid
Boards can be used for explanation. For example, teachers
can show the relationship between and affrimative sentence
and a question by drawing connecting arrows. The board is
ideal for such use.
3). Public workbook
Teachers can ask students to come forward and do the
exercise on the board. The exercise can be in form of fill-in
items or sentence transformation. Teachers also sometimes
write mistakes and ask class members who think they know to
correct them.
4). Game board
There are a number of games that can be played using the
board. One of the games is a spelling game that involves two
teams who start off with the same word. Each team has half the
board. They have to fill up their side with asmany word as
possible, but eacg new word has to start with the las letter of
the word before. At the end of a given period of time, the team
with the largest number of correct words is the winner.

h. Overhead Projector (OHP)
Overhead Projector (OHP) is considered as an old- fashioned
teaching medium. However, by using overhead projectors, the students
can see in front of the class the material which is written or drawn in a
transparent. The transparent will be projected by using projectors.
i. Flipcharts
Another instructional medium that may be used by the teacher is
flipchart. Flipchart is an instructional medium which contains big
sheets of paper. It is mostly used to write down some important points
in group discussion (Harmer, 2007). Several benefits of flipchart are
portable, accessible, and easy to use.
j. Computer-based presentation technology
Computer is becoming a very important tool of doing many things.
Harmer (2007) said that computer-based presentation technology has
two vital components. They are hardware and software. Anything that
is on the computer screen can be shown to the whole class using data
projector to put up enlarged version of it. This instructional media
combine both audio and visual material. By using computer-based
presentation technology, it enables the teacher to convey much larger
information to the students.
Beside those kinds of instructional media explained above, the
other media that commonly used by teacher is real object. Real object can
be used for many purposes such as teaching pronunciation, vocabulary and
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
15
grammar. Students understand and retain the meaning of words better
when they have been shown or have touched some objects. Real object
also can be used by the teacher when students are to find out important
facts or information and concepts (Cole&Chan, 1994: 129).
From the description about the instructional media above, it can be
concluded that there are many types of instructional media that can be
used in teaching learning activities. Those different types help teacher in
different teaching-learning activities and materials.
2. Contribution of Media to the Learning Process
Media are expected to have crucial roles in learning process. Media
assist the teacher during the instructional process. Media help teachers and
instructors manage instruction more effectively. According to Kemp and
Dayton (1985: 3-4), there are six contributions of using media to the
learning process, they are:
a. The instruction can be more interesting.
There is an attention-getting factor associated with instructional
media that keeps manners of an audience alert. The attractiveness of
changing images, the use of special effects, and the impact of ideas
that can arouse curiosity cause an audience to laugh or to be
thoughtful; all contribute to the motivational and interest-creating
aspects of instructional media.

16
b. The length of time required for instruction can be reduced.
Most media presentations require a short time to transmit their
messages. But, during this short period, a large amount of information
can be communicated to and absorbed by the learner. This can lead to
greater efficiency in the use of time for both the instructor and the
student during the instructional process.
c. The quality of learning can be improved.
When there is a careful integration of pictures and words,
instructional media can communicate elements of knowledge in a well-
organized specific and clearly defined manner. As a result, with
suitable study effort on the part of the student appropriate follow-up
activities, learning can be expected to reach an acceptable competency
level.
d. The instruction can be provided when and where desired or necessary.
When instructional media are designed for individualized use, then
a student can study at a time and place that is personally convenient.
This flexibility is particularly important when individuals must
integrate study activities with vocational and personal responsibilities.
e. The positive attitude of students toward what they are learning and to
the learning process itself can be enhanced.
Students frequently express preference of using media as a means
of studying. This may be due to both the motivational aspect and the
contributions that media can make to a person‟s success in learning.
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
17
Students find learning with instructional media both enjoyable and
satisfying.
f. The role of instructor can be appreciably changed in positive direction.
While most benefits for the use of instructional media are directed
to the student and to his or her accomplishment in learning, there are
advantages also for the instructor. First, much of the burden of
repeated explanations of content and skills can be eliminated. Second,
by not having to present as much information verbally, other, possibly
more important aspects of a course can be given attention. Third, the
instructor has increased opportunity to fulfill the role of being a
consultant and advisor for students.
On a whole, it can be seen that the use of media is very helpful
because media give many contributions to the instructional process for
both the teacher and the students.
3. Selection of Media
There are many elements that affect English teaching process. For
effective teaching to take place there should be a blending between the
content, performance and instructional media. Instructional media are all
kinds of media used in teaching process to help achieving the intended
learning outcomes. However, the use of instructional media needs to be
carefully made and planned. Therefore, it must be born in mind that the
teacher has to select the appropriate media to support the learning process.
The teacher should follow some considerations in using instructional
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
18
media in order to avoid difficulties and mistakes in using it for their
teaching activities.
In selecting media, Reiser and Dick (1996) as cited in Aini (2013)
believe that in selecting instructional media, the teachers should consider
three main factors comprising:
1. Practicality
Practicality of instructional media includes the availability of the
media, the cost, and the time efficiency. The availability of media
means that the intended media are readily available or not. If it is not,
the teachers must consider the cost spent is in accordance with the
educational result derived from its use if they decide to make or buy
the media needed. Besides, it also should be easy to be used and
understood by the teacher so that it doesn‟t require much time to
prepare.
2. Students‟ appropriateness
a. Appropriateness of instructional media with students‟
characteristics
It means that the media should be appropriate with students‟
interest, students‟ motivation, students‟ need and students‟
diversity.
b. Appropriateness of instructional media with learning condition
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
19
It should be considered that to select the appropriate media, a
teacher needs to consider the level of the students, the number of
students and the classroom setting.
3. Instructional appropriateness
a. Appropriateness of instructional media with the material.
It means that the media used should have significant relation with
the content of the material that will be given to the students.
b. Appropriateness of instructional media with the instructional goal
In selecting media, teacher should consider the goals of instruction
that will be achieved. Then, teacher has to analyze whether the
media are suitable with the intended learning objectives or not.
c. Appropriateness of instructional media with the activity
This means media that will be used should be appropriate for the
planned instructional strategy and facilitate the students‟
acquisition of the specific learning objectives.
In short, there should be some considerations in deciding the
instructional media that will be used, besides knowing the students‟
characteristics; the teacher should pay attention to several principles in
selecting the appropriate media to make a better result of teaching.
D. Media in English Teaching Process
The English teachers should use many ways of presenting
materials. Instructional media is a tool to facilitate this. Teachers should
use media whenever it can facilitate learning or increase students‟
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
20
understanding of the material. Besides, media also help the teacher to
present concepts in more concrete approaches.
When media is integrated in the teaching learning process, it
leads the learning to be faster and enjoyable learning. Further, the use
instructional media also is very effective in teaching by providing
concrete experiences, increasing retention and giving variety of
learning.
Media that employ visual such as pictures and videos in
teaching appeal to eye because of the attractiveness of changing images
and the use of special effects. They attract attention, interest and
increase retention. They can convey message in a better way than words
could do. Such aids in teaching are closer to real life situation. They
help to save teaching time because they can speed up the learning
process better than lengthy descriptions if words are to be used.
Meanwhile, instructional media that are auditory help to increase the
sense of hearing. This kind of media is good for teaching listening skill
(Wamalwa & Wamalwa, 2014).
Many significant benefits offered by using media. When the
students get involved in using media in teaching learning process, they
will get a concrete experience. The use of media such as realia or real
objects can attract students‟ interest and curiosity. Harmer (2001: 177)
asserts that objects that are intrinsically interesting can provide a good
starting-point for a variety of language work and communication
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
21
activities. Those objects for example might be a hair ribbon, a pen, a
telephone, a bottle and a key. Teacher can emphasize the meaning of
the objects by showing and demonstrating them into some relevant
activities. Teachers can make students to get involved in using them by
asking the students to pick one of those objects and make sentences
based on the object they get. Then they are asked to share their ideas in
front of the class.
Media such as cards also can be utilized for several activities.
Teachers can write words on separate cards and after shuffling them,
place them in a pile face down. When a student picks up a card, he/ she
has to use the word in a sentence. Alternatively, student can choose a
card and try to describe what word is it, and ask the other students to
guess it. Teacher also can make situational cards and ask students to
work in pairs. Then each pair should choose one of them and ask them
to make a conversation based on the card they have got. Then the
students are asked to do a role play in front of the class. Beside those
activities, cards can be used to many other activities with different
purposes. Other instructional media also can be utilized in various
activities depend on the purpose and the creativity of using them.
The use of various forms of instructional media and technology
in teaching, whether new or old, can have a great impact on student
learning (Wamalwa & Wamalwa, 2014). When they are used
effectively, those varieties of media will encourage student
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
22
participation, and help students to understand difficult concepts. When
they are used poorly, these same tools can obscure instructional
objectives and make students confused.
From the explanation above, it can be concluded that
instructional media are integral part of teaching and learning process.
The utilization of various forms of instructional media helps to enhance
learning.
E. Previous Research Findings
Many researches have been conducted to investigate about the
utilization of instructional media in teaching English. Wildan Nurul
Aini (2013) in her research entitled “The Utilization of Instructional
Media in Teaching English to Young Learner” investigated about the
use of instructional media by the teachers in teaching English to young
learners, the problems that they encounter in using instructional media
and also problem solving of the media utilization challenges. This study
was conducted in elementary schools in Kuningan. To collect the data,
the researcher employed observation and interview techniques. The
result showed that there were five types of instructional media which
are generally used by the teachers, comprising: (1) boards; (2) realia;
(3) pictures; and (4) books. Each of them was used in various ways. The
teachers faced challenges in both process of selecting and using
instructional media. The strategy used to solve the problems during
selection process was utilizing available media. Meanwhile, to
The Utilization of Instructional Media..., Umu Sholihatin, FKIP UMP, 2017
23
overcome the problem during the use of instructional media were by
requesting technician help, borrowing instructional media supply from
other class and preparing back-up instructional media.
Another researcher also investigates the same topic. A research
entitled “The Utilization of Instructional Media in Teaching English to
Young Learner” by Tanti Sukmahidayanti (2015) aimed to describe the
teacher‟s preparation and to explain how the teacher utilized the
instructional media in the classroom. The subject of the study was
English teachers in an elementary school in Bandung. This study used
observation, interview and data analysis to obtain the data. The result of
this study showed that the teacher did two kinds of preparation in
utilizing the instructional media, reading the materials and choosing the
media. In utilizing the media, the teacher utilized the provided media in
the school and did not utilize it optimally due to several challenges,
such as limitation of time, difficulty in selecting media, lack of media
availability, and teacher‟s negative belief towards instructional media
and the system.
Those previous researches have the relation with this current
research. Both of them had investigated the utilization of instructional
media in teaching learning process. This research also investigated the
same topic about utilization of instructional media but it had different
subject of the research. The subjects of both researches were English
