The communication path
Communication has five parts. The sender is the person or group who wants to tell something. The message is the idea, made into words, pictures or sounds. The medium is the carrier: a poster, a video, a letter, a phone call, a web page. The receiver is the person who gets it. Feedback is the reply that tells the sender if the message was understood.
Communication is only complete when the receiver understands. Sending is not enough.
Choosing the right medium
No medium is best for everyone. Ask three questions: Who is the receiver (age, language, what they have)? What is the message (a quick alert or a long story)? Where will they meet it (street, phone, classroom)?
- A poster is good for a short message that many people pass by.
- A video is good to show how something moves or to tell a feeling.
- Text is good for detail that people may read again and again.
- A voice message helps people who cannot read well.
Noise: what spoils a message
Noise is anything that stops a message from being understood. It can be real sound (a loud street), but also: too many words, tiny letters, colours that clash, a hard language, a bad phone signal, or a receiver who is tired or busy.
To beat noise: keep one main idea, use big clear words and pictures, leave empty space, use a language the receiver knows, and repeat the key point once.
Exchange and feedback
Good communication is a two-way exchange. After you send, ask: "Did you understand?" The receiver may smile, ask a question, click a like button, reply or act. This is feedback. Use it to fix the message. A teacher who sees puzzled faces explains again in a simpler way. That is feedback at work.
Sharing: one message, many people
Digital media let one message reach many people in seconds. Before you share, check three things. Truth: is it correct? Look for the source. Credit: if you use another person's picture, music or words, say whose it is and ask if you may. Privacy and kindness: do not share photos or details of people without their permission, and do not share messages that hurt.
A message you share can be copied again and again, so you cannot fully take it back.
Try it: the 2-minute message test
Write a message to tell your class about a school event. Make two versions: a long, crowded one and a short, simple one with one picture. Show each to a friend for 5 seconds, then ask what they remember. Which version worked? In the 3D above, tick or untick "Simple message" and see how much arrives.
Key formulas and definitions
- Sender → Message → Medium → Receiver → Feedback
- Understood = message arrives + receiver can make sense of it
- Medium choice: Who? What? Where?
- Before sharing: True, Kind, Clear (T-K-C)
Worked examples
1. You want to tell people in a busy railway station that a lost child is waiting at the help desk. Which medium and why?
A loud-speaker announcement. People are walking and cannot stop to read. A voice reaches everyone at once and the message is short and urgent.
2. A poster has 120 words in tiny letters and three colours of bright text. Name two kinds of noise and fix them.
Too many words and clashing colours (also tiny letters). Fix: keep one main idea in about 10 words, use big letters, one or two calm colours and one picture.
3. You send a group message, but nobody replies. How do you get feedback?
Ask a clear question ("Can you come on Friday? Reply yes or no"), or ask a friend in person what they understood. Then change the message if it was unclear.
4. A friend shares a shocking news post. What do you check before sharing it further?
Is it true (look for the original source), who made it, does it hurt anyone, and do I have permission if it has a photo of a person. If not sure, do not share.
5. You use a photo of a river from the internet in your video. What is the right thing to do?
Find out who made it, ask permission or use pictures that are free to use, and write the name of the photographer in your video credits.
6. A message goes to 6 people. 4 understood and replied. What fraction understood? What would you try?
4 out of 6 = 2/3. Try a simpler message or a different medium for the 2 who did not understand, and ask them what was confusing.
Common mistakes
- Thinking the job is done when the message is sent. It is done when the receiver understands.
- Using one medium for everyone. A long text may not work for small children or for people who cannot read.
- Putting too much in one message, so the main idea is lost in noise.
- Sharing posts without checking if they are true, or sharing photos of people without asking them.
