Concept of Teaching Learning Vocabulary
3. Hardware and software.
Hardware is meant application of machines, gadgets or equipment to improve the quality of education, such as
video player, television, walkie- talkie, disc machines and other teaching machines. Then, software covers
Microsoft PowerPoint, Microsoft Word, Windows Media Player, etc.
This research used the combination of those teaching aids above, they are projected, visual and software aids. The projected aid used is LCD projector,
while the visual aid used is picture. Besides, the software used is Microsoft PowerPoint. Those teaching aids above are explained as follows:
1. LCD liquid crystal display Projector
LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of
the slide projector or overhead projector. 2.
Picture Picture is painting, drawing, etc, that shows a scene, a person and thing; a
description that gives you an idea in your mind of what something is like. Gerlach and Emily 1980: 273 state that picture is a two dimension visual
representation of person, places, or things. 3.
Microsoft PowerPoint It is software which consists of a number of individual pages or slides.
Slides may contain text, graphics, sound, movies, and other objects, which may be arranged freely.
This research focused on teaching medium used; that is projected picture. It is a picture which is visualized through Microsoft PowerPoint on
a screenwall using LCD projector.
LCD projector is used to enlarge the image to be more sharp and clear.
The main teaching medium in this research is picture, while LCD projector and Microsoft PowerPoint just support it.
By using picture, it will make the children easier to remember and understand the new vocabulary that they get. As
Brown 2001: 143 states that picture is ‘old-fashioned but that is very helpful as media in an instruction’. Picture specifically can directly get students’
attention the first time they see it. Moreover, Wright 1994: 4-5 states that picture can be used as a reference and stimulus in order to provide five
different language teaching emphases, such as structures, vocabulary, functions, situations and skills. As Thornbury 2004: 25 advises to visualize a
picture for a new word or to link an abstract word with some mental image. Therefore, there are some roles of projected picture in teaching learning
process. In this case, the roles of picture stated by Wright 1994: 17 will be explained as follow:
1. Pictures can motivate the students and make them pay attention and take a
part in learning. 2.
Pictures contribute to the context in which the language is being used, such as bring the world into the classroom an object or situation such as a train,
winter, etc..
3. Pictures can be described in an objective way, e.g. ’this is a blender’ or it
can be interpreted, e.g. ‘it is avocado juice’ or responded to subjectively, e.g. ‘I like drinking avocado juice’.
4. Pictures can prompt responses to questions or bring substitutions through
controlled practice.
In addition, according to Gerlach and Emily 1980: 277, there are some advantages of using picture as teaching medium as follow:
1. They are inexpensive and widely available.
2. They provide common experiences for an entire group.
3. The visual detail make it possible to study subject, which would turn back
to be impossible. 4.
They can help you to prevent and correct disconcertion. 5.
They offer a stimulus to further study, reading and research visual evidence is power tool.
6. They help to focus attention and to develop critical judgment.
7. They are easily manipulated.
Whereas, there are some disadvantages of using picture as teaching medium as follow:
1. Students pay attention on the picture more than on learned material.
2. It takes time and costs much to provide attractive pictures.
3. Small and unclear pictures may arouse problems in the teaching learning
process since the students may misunderstand about the pictures.
