Unit 1: Communication Skills – Class 10 IT 402
Chapter 1: Methods of Communication (Notes & Summary)
1. Introduction
Communication means sharing ideas, thoughts, or feelings with others. It allows people to understand each other, build relationships, and work together effectively.
2. Three Main Parts of Communication
- Transmitting – The sender delivers a message.
- Listening – The receiver pays attention and understands.
- Feedback – The receiver responds, completing the cycle.
3. Elements of Communication
- Sender – Person sending the message.
- Message – Information or idea being shared.
- Channel – Medium (spoken words, writing, visuals, etc.).
- Receiver – Person receiving the message.
- Feedback – Response given by the receiver.
4. Methods of Communication
- Face-to-face – Direct interaction; quick and clear.
- Emails & letters – Written record for personal/professional use.
- Notices, posters, circulars – To reach many people at once.
- Meetings – Exchange of ideas in groups.
- Digital tools – Social media, blogs, video calls, messaging apps.
5. Verbal Communication
- Communication through words, speech, or writing.
Types:
- Interpersonal (one-to-one)
- Written (letters, e-mails, reports)
- Group (team discussions, press meets)
- Public (speeches, debates)
Pros: Quick, flexible, personal connection.
Cons: Misunderstood easily, spoken form has no permanent proof.
Tips: Be clear, think before speaking, use confident tone and body language.
6. Non-Verbal Communication
- Expression without words – through gestures, expressions, posture, eye contact, and tone of voice.
- Example: A smile shows friendliness, a frown shows displeasure.
- Non-verbal cues often express feelings better than words.
7. Visual Communication
- Uses images, symbols, charts, posters, and diagrams.
- Easy to understand, attractive, and leaves a lasting impression.
Chapter 2: Verbal and Non-Verbal Communication (Notes & Summary)
1. What is Verbal Communication?
Verbal communication means sharing information using spoken or written words. It is the most common method to express ideas clearly.
Types of Verbal Communication:
- Interpersonal – One-to-one conversations.
- Written – Letters, SMS, e-mails, reports.
- Group Communication – Team discussions, press conferences.
- Public Communication – Speeches, debates, rallies.
Advantages:
- Quick feedback
- Easy to use
- Builds personal connection
Disadvantages:
- May be misunderstood
- No permanent proof (in case of spoken)
- Depends on clarity of words and tone
2. What is Non-Verbal Communication?
Non-verbal communication is the process of expressing ideas without words. It includes gestures, body movements, and facial expressions.
Examples of Non-Verbal Communication:
- Handshake, nodding, or waving
- Smile or frown
- Posture, walking style, eye contact
- Tone of voice and silence
Importance:
- Strengthens verbal messages
- Shows emotions better than words
- Helps build trust and understanding
3. Difference Between Verbal & Non-Verbal Communication
| Verbal | Non-Verbal |
|---|---|
| Uses words (spoken/written) | Uses gestures, tone, body language |
| Easy to record (letters, e-mails) | Cannot be stored or recorded |
| May be quick but needs clarity | Works instantly, often unconscious |
| Example: Meeting discussion | Example: Smiling to greet someone |
4. Combining Verbal and Non-Verbal
The most effective communication happens when both methods are used together. For example:
-
In a classroom, a teacher’s words (verbal) with eye contact and gestures (non-verbal) make learning more engaging.
-
In presentations, spoken explanations plus charts/expressions convey the message strongly.
5. Tips for Effective Communication
- Think before you speak.
- Match your body language with your words.
- Maintain eye contact and a friendly posture.
- Use simple, clear words.
- Listen carefully and respond with respect.
Quick Recap Table
| Topic | Key Points |
|---|---|
| Verbal Communication | Uses words – spoken/written. |
| Non-Verbal Communication | Gestures, tone, body posture. |
| Advantages of Verbal | Quick, builds connection. |
| Disadvantages of Verbal | Misunderstood, no record. |
| Importance of Non-Verbal | Shows emotions, builds trust. |
| Best Practice | Combine verbal + non-verbal. |
Chapter 3: Communication Cycle and Feedback (Notes & Summary)
1. Communication Cycle
The communication cycle is the process of exchanging information between two or more people. It shows how a message starts, travels, and comes back with feedback.
Steps of the Communication Cycle:
- Sender – The person who creates and shares the message.
- Message – The information, thought, or idea being shared.
- Encoding – Converting the idea into words, symbols, or gestures.
- Channel – Medium used (speech, writing, visuals, digital).
- Receiver – The person who receives the message.
- Decoding – Understanding and interpreting the message.
- Feedback – The response given by the receiver.
👉 Without feedback, communication remains incomplete.
2. Importance of Feedback
Feedback tells the sender whether the message was understood correctly. It helps improve communication and avoid confusion.
Types of Feedback:
- Positive Feedback – Agreement, appreciation, nodding, clapping.
- Negative Feedback – Disagreement, confusion, silence, rejection.
- Constructive Feedback – Helpful suggestions given in a polite way.
3. Qualities of Good Feedback
- Clear – Easy to understand.
- Specific – Focused on one issue at a time.
- Helpful – Aims to improve, not to insult.
- Timely – Given immediately or soon after the communication.
- Respectful – Delivered politely, maintaining trust.
4. Barriers to Feedback
Sometimes feedback is not effective because of:
- Lack of attention from the receiver.
- Poor listening skills.
- Fear of speaking honestly.
- Language or cultural differences.
- Sender not open to criticism.
5. Tips for Giving Effective Feedback
- Be polite and positive.
- Mention what went well before pointing out mistakes.
- Suggest solutions instead of only criticizing.
- Use simple words and a calm tone.
- Always give feedback face-to-face when possible.
