(3.3) Vocabulary and Oral Communication — Literacy

A student can’t write an essay or present a science project if they lack the words to express their thoughts or the confidence to speak clearly.

As a teacher, you must know how to build your student’s vocabulary and turn a passive classroom into an active space for academic discussion.

1. Vocabulary Instruction

Use a mix of both direct and indirect methods to expand a student’s word bank.

Direct vocabulary instruction

Teaching specific words with structural learning strategies, vital for subject-specific terms (e.g., photosynthesis in Science or isosceles in Maths).

• The Frayer Model: A strategy where students define a word, describe its characteristics, and provide examples and non-examples.

Indirect vocabulary instruction

Helping students learn words naturally through everyday language experiences.

• Strategies: Encouraging wide independent reading, reading aloud to the class and engaging students in active conversations.

2. Morphology

This is the study of word structures and how words are formed.

Teaching students to look at word parts gives them a “decoder key” to figure out unfamiliar words across all subjects without needing a dictionary.

Roots

The core base of the word that holds the fundamental meaning.

Many academic words in Nigeria’s curriculum come from Greek or Latin roots.

• Bio = life
• Geo = earth.

Prefixes

Added to the beginning of a root word to change its meaning.

• Mis- (badly/wrongly: misunderstood)
• Anti- (against: antibiotic)
• Un- (not: uncomfortable)

Suffixes

Added to the end of a root word to change the word’s part of speech or tense.

• -ful (turns a noun into an adjective: beautiful)
• -logy (the study of: biology)
• -less (without: hopeless)

3. Active Listening and Class Discussions

Oral literacy requires a two-way street: speaking clearly and listening actively.

Active listening techniques

Teachers must train students to listen with intent, not just wait for their turn to speak.

Paraphrasing

Asking a student to restate what their peer just said in their own words (“So, Chinedu, what I hear you saying is…”).

Non-verbal cues

Teaching eye contact, nodding, and alert posture during a lesson or peer presentation.

Clarifying questions

Encouraging students to ask questions based on what they just heard (“Could you explain what you meant by that last point?”).

Strategies for Class Discussions

To move away from the traditional “teacher talks, students sleep” model, use these structured discussion formats:

Think-Pair-Share

• Think: Teacher asks a question; students think for 1 minute.
• Pair: Students turn to their desk partner to discuss their ideas.
• Share: The pairs share their conclusions with the rest of the class.

Socratic seminars

Students sit in a circle and lead the discussion themselves, asking open-ended questions about a text or topic while the teacher acts as a silent observer.

Turn-and-Talk

A quick, 30-second low-stakes discussion with a neighbour to process a complex point after the teacher explains it.

4. Oral Presentation Skills

Public speaking can terrify students.

A certified teacher provides scaffolding to build their confidence gradually.

Show-and-Tell

Start early in primary or junior secondary by letting students bring a familiar object and talk about it for 1 minute.

P.O.V.E.R. for speaking

• Projection: Speak loud enough for the student at the back to hear without straining.
• Organization: Have a clear introduction, body, and conclusion.
• Velocity: Speak at a steady, calm pace, not rushing through sentences.
• Eye contact: Look at the audience, not just reading word-for-word off a paper or slide.
• Respect: Be polite and handle audience questions gracefully.
