b. Television
Television is defined by people from the word television audio-

visual, which means a tool/means for channelling images (sound images).
The television set was invented by a German named J.L. Baird in 1926,
followed by Americans in 1941. It is still black and white television. It

was only in the 1960s that colour television could be invented. Television
can be used as a medium of learning because with television, viewers can

add socio-cultural knowledge, insight into thinking, attitudes, and the
possibility of other skills.
In broadcasting ideas, television is multi-dimensional, meaning that

apart from being able to hear and see what is being broadcast, it is hoped
that it will also affect motivation, attention, creativity, imagination, and

emotion.
The contents of broadcast television programs can be in the form of
science and matters relating to the economy, politics, society, culture,

government, defence and security, environment, and community.
Submission of messages, information, or learning materials through
television media can use examples of broadcast forms, including:

1) Lectures means that through television, a person can convey his
ideas by lecturing.
2) Interviews means that television programs can present their

broadcasts in the form of questions and answers/interviews
3) Discussion, meaning television. Also broadcasts the ideas of

several people by way of discussions or panel discussions
4) Play/show means that the idea of a group of people can be
realized in the form of a play.

The advantages of using television as a learning medium are::
1) Presenting images and sound together

2) Very eye-catching for the audience
3) Sparking curiosity in children so as to encourage the emergence
of children's creativity.
