ELECTION, PLANNING, PRODUCING, MAINTANCE SIMPLE MEDIA

• ELECTION
To choose media technology, must appropriate with the material of lesson.
Learning election divided 2 methods there are:
Direct learning is teacher as the center from learning process and for examples of these methods are speech, practices and exercises.
Indirect learning is students involved to do action/observation. In here teacher just be facilitator.

• PLANNING
Planning as prepare media to be used in process teaching and learning.
Process in teaching to decide and formulate with consistent decision to make process of teaching and learning very well.

• PRODUCING
There are several useful, one of those tech-edutech more of them very important, and the last affectivity in simple media.

• MAINTENANCE
All media that we used in educational technology so important, therefore those media including audio, visual, and audio-visual must be kept and maintained well.

• 5 MEDIAS :
1. AUDIO : RADIO AND EARPHONE
2. VISUAL : MAP AND REALIA
3. AUDIO-VISUAL : LAPTOP

1. RADIO

• Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light.
• Radio can be detected and transformed into sound or other signals that carry information.
• Radio included audio representation (you just can hear).
• English lesson usually uses a radio, especially for listening section.
The advantages of radio are :
We can get information about everything.
With radio, we can hear sounds and voice clearly.
Radio is a universal medium enjoyed by people at one time or another during the day at home, at work in office or school, and even in the car.
The disadvantages of radio are :
We cannot go back to ask important or misunderstand points.
Radio is a background medium. Most listeners are doing something else while listening, which means that your ad has to work hard to get their attention.
Radio also can add to electricity payment in office or school.

EARPHONE
• A device that converts electric signals, as from a telephone, stereo, or radio receiver, to audible sound and fits over or in the ear.
• Earphone is a pair of small loudspeakers, or less commonly a single speaker, with a way of holding them close to a user's ears and a means of connecting them to a signal source such as an audio amplifier, radio or CD player.
• We are also known as headphone, earpiece, or stereo phones.
• Earphone is audio representation (you just can hear).
• English lesson usually also uses an earphone, especially for listening section in English laboratory.
The advantages use earphones are :
Earphone heard clearly than radio.
Earphone can connect with an audio amplifier, radio or CD player.
The disadvantages use earphones are :
If earphone be used continuous, can damage sense of hearing.
We can not hear clearly the voice when in outside heard noisy.

2. MAP

• Map is objects from real life or from the real world, as opposed to theoretical constructs or fabricated examples; especially, such objects used as instructional or classroom aids.
• Map is a visual representation (you just can see) an area, a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes.
• Geography lesson especially in elementary school and junior high school usually uses a map to represent any space, real or imagined without regard to context or scale, for example; mapping.

The advantages use maps are :
Map gives a beautiful and a current pictorial view.
We can know the province name and location in the area or in the states.
We can be facilitated by map to looking for the locations or places in the areas.
The disadvantages use maps are :
Position location and scale are only approximate.
For students in elementary school, they are usually difficult to identify without symbols, and are often obscured other ground detail as, for example; buildings in wooded areas.
We need a long time to make a map.
REALIA
• In education, realia (barang tiruan) are objects from real life used in classroom instruction by teacher to improve students understanding of other cultures and real life situations.
• Realia is a visual representation (you just can see).
• Science and Mathematics usually use realia to strengthen students as real objects.
The advantages use realia are :
Students can see and understand the objects like real life.
 All students can be creative to make a realia, for example in Mathematics lesson, the students can make space buildings (bangun ruang) like cube, beam, prism, pyramid and etc.
Give a real experience for all students.
Durable (tahan lama/awet).
The disadvantages use realia are:
Not all school has a good and enough realia.
Sometimes, realia is too difficult to get.

3. LAPTOP

• Laptop is a portable computer small enough to use in your lap.
• A Laptop is a personal computers designed for mobile use and small and lights enough to sit on a person's lap while in use.
• Laptop includes a screen, keyboard, and a track pad or trackball, which serves as the mouse.
• Laptop is audio-visual representation (you can hear and also see).
• Laptop is modern media education because laptop can be used to explain all lessons in school.


The advantages of laptop are :
Getting more work done. For example, students doing his/her homework at the school or university coffee shop during a break between lessons.
Immediacy. Carrying a laptop means having instant access to various information, personal and work files.
Up-to-date information
Connectivity can use Wi-Fi wireless networks, internet and local network connectivity others while remaining mobile.
The disadvantages of laptop are :
Laptop is too difficult to repair, upgrade or modify due to their closed and integrated design.
While in a desktop computer the possible configurations are almost unlimited, laptop configurations are limited to those provided by laptop manufacturers.
Laptop is an expensive media technology.
We must often recharge the battery from laptop because laptop needs a power after to be used.
