To start you'll have to take in mind Mass Communication Research, The Hipodermic Needle Theory, developed by Lasswell: "Propaganda Techniques in World War".
A few practical points about this theory:
- In this communication model, the messagge is sent and recieved with the same meaning the transmitter wanted to be. The receptor accept the messagge just as it's sent: he doesn't analyze it.
- According to Lasswell, the propaganda is useful to manipulate the masses, without violence.
- The Hipodermic Needle Theory it compares mass media communication with a needle that "injects" a messagge or information and the receptor just take that as true.
- This is a conductive theory: to a certain cause you have an effect. You look for a concrete and measurable effect.
Applying this theory to your HW, you want to obtain an effect: convincing colinist to fight british opression. So your message / poster will have to imitate the structure of The Hipodermic Needle Theory's popaganda:
For example, in WW2 the nazi propaganda focused on demonizing a common "enemy": jews. They sent several messagges through different channels such as movies, posters, speeches, just to get people aproval on every "hate actions" they developed.
in this example we can analyze that it's a "two sides" situation: you are with the enemy or you are with the "good side".
So you will have to do some reaserch and look for information which can help you to develop the kind of message I showed you in the example.
Hope it helps!!! Good Luck!
