Classroom Communication and Teaching

Classroom communication is the purposeful, structured exchange of ideas and information between teacher and students (and among students) to achieve learning objectives. It is generally face to face, goal-directed, and involves verbal, non-verbal and visual elements.

• One-way (teacher to student): lecture; feedback is minimal.

• Two-way (teacher to student and back): question-answer, response, feedback.

• Three-way / multi-way (interaction among students and teacher): group work, discussion, peer teaching. Considered the most effective for active learning.

• Clear objectives and well-organised content, simple and audible language.

• Use of examples, analogies and learner-appropriate vocabulary.

• Effective questioning (clear, brief, graded, distributed fairly, with adequate wait time).

• Feedback: immediate, specific, constructive and encouraging.

• Use of teaching aids and ICT to support communication.

• Positive classroom climate, empathy, and acceptance of student ideas.

• Awareness of individual differences, language and cultural background of learners.

Ned Flanders developed the system to observe and quantify verbal behaviour in the classroom. It has 10 categories, observed typically every 3 seconds:

• Teacher talk – indirect influence (1 to 4): 1 accepts feelings; 2 praises or encourages; 3 accepts or uses students' ideas; 4 asks questions.

• Teacher talk – direct influence (5 to 7): 5 lecturing; 6 giving directions; 7 criticising or justifying authority.

• Student talk (8 and 9): 8 student talk – response; 9 student talk – initiation.

• Silence or confusion (10).

(Teacher talk = 7 categories; student talk = 2; silence = 1.) A classroom with more indirect influence is seen as more democratic and learner-friendly.

A model showing a continuum from concrete (direct, purposeful experiences) at the base to abstract (visual and verbal symbols) at the top. The message: use varied, concrete, multi-sensory experiences for stronger understanding. (Popular percentages linked to the cone are not Dale's own research findings, so do not rely on them.)

Language mismatch, poor audibility, a large class size, monotonous delivery, teacher-centred approach, lack of feedback, student anxiety or disinterest, prejudice, inadequate teaching aids, physical discomfort and noise, and distractions from mobile phones.

Plan the lesson, use varied methods and media, encourage questions, vary pitch and pace, use positive reinforcement, arrange seating for interaction, use ICT meaningfully, maintain eye contact, and be sensitive to diversity.

• Teaching is a communication process: teacher (sender) → content (message) → methods and media (channels) → learner (receiver) → feedback.

• Effective teacher communication is clear, learner-centric, interactive, supported by ICT, and aware of barriers.

• Verbal, non-verbal and visual modes combine in teaching aids (chalkboard, projector, videos, simulations).

• Online and blended learning rely on asynchronous and synchronous communication (discussion forums, video lectures), and need netiquette and digital literacy.

• Feedback should be timely, specific, constructive, and should focus on performance, not the person.

Imagine an observer sitting at the back with a stopwatch. Every 3 seconds he writes a number from 1 to 10 for what is happening.

• 1 Accepts feelings: "I can see this topic is worrying you."

• 2 Praises or encourages: "Very good", "Go on."

• 3 Accepts or uses students' ideas: "So, as Rahul suggested, we can try this method."

• 4 Asks questions: "Why do you think it happens?"

• 5 Lectures: giving facts, opinions or explanation.

• 6 Gives directions: "Open page 45."

• 7 Criticises or justifies authority: "Sit down, I am the teacher here."

• 8 Student talk, response: answering the teacher's question.

• 9 Student talk, initiation: asking their own question or sharing their own idea.

• 10 Silence or confusion: pauses, noise, or periods where communication cannot be understood.

How to remember: 1 to 4 = indirect teacher influence (encourages freedom); 5 to 7 = direct influence (restricts freedom); 8 to 9 = student talk; 10 = silence/confusion.

Useful ratios (simple meaning):

• Teacher talk ratio: percentage of time the teacher talks.

• Student talk ratio: percentage of time students talk.

• I/D ratio (indirect/direct): more indirect than direct means a more democratic, student-friendly classroom.

• Flanders' rule of two-thirds: in a typical classroom, about two-thirds of the time someone is talking; about two-thirds of that is the teacher talking; and about two-thirds of the teacher's talk is direct influence. This highlights how teacher-dominated most classes are.

• Low-order questions: recall facts ("What is the capital of India?").

• High-order questions: analyse, evaluate, create ("Why might this policy fail?").

• Wait time: pausing after a question (research by Mary Budd Rowe suggests around 3 seconds or more) leads to longer, better answers from more students.

• Good practice: ask the question first, pause, then choose who answers; give every student a chance; and respond with praise or probing rather than humiliation.

• Positive / encouraging: reinforces correct work.

• Corrective / constructive: shows what to improve and how.

• Immediate vs delayed: immediate feedback works best for new skills.

• Formative (during learning) vs summative (at the end).

From most concrete to most abstract:

1. Direct, purposeful experiences

2. Contrived experiences (models, simulations)

3. Dramatized experiences (role-play)

4. Demonstrations

5. Field trips

6. Exhibits

7. Educational television

8. Motion pictures

9. Recordings, radio and still pictures

10. Visual symbols (charts, maps)

11. Verbal symbols (spoken and written words)

Idea: learners understand better when teaching moves from concrete experience toward abstract ideas and uses multiple senses. Exam cue: the base is direct purposeful experience; the top is verbal symbols.

• Starts with a clear aim and connects to what students already know.

• Speaks audibly and not too fast, and varies pitch to avoid monotony.

• Uses simple examples and teaching aids.

• Watches students' faces to catch confusion early.

• Encourages questions and treats mistakes as part of learning.

• Uses inclusive language and respects different backgrounds.

• Ends by summarising and checking understanding.
