Active vs. passive voice — deliberate choice for effect

Read aloud: 'The experiment was conducted under controlled conditions.' Who conducted it?

• Affirm: the sentence doesn't tell us — the actor is OMITTED
• Connect: this is PASSIVE VOICE — emphasizing the action; de-emphasizing or hiding the actor

Today we work with VOICE — active vs. passive. ACTIVE VOICE: subject (actor) + verb (action) + object (acted-upon). 'Smith argues that climate change is accelerating.' Smith is the actor; argues is the action. PASSIVE VOICE: subject (acted-upon) + 'be' verb + past participle + (optional 'by' agent). 'Climate change is argued to be accelerating by Smith.' The acted-upon (climate change) is now the subject; the actor (Smith) is in a by-phrase, or omitted. Why both? They serve DIFFERENT rhetorical purposes. ACTIVE emphasizes the ACTOR. PASSIVE emphasizes the ACTION or de-emphasizes the actor. Many writing handbooks oversimplify and say 'avoid passive voice.' That's wrong. Both have legitimate uses. ACTIVE is the default for argumentative writing — we want to know who's arguing what. PASSIVE is the default for scientific procedure — what was done matters more than who did it. 'The mixture was heated to 80°C.' We don't care WHO heated it; we care that it was heated. Joseph Williams's actor-action clarity routine: figure out who/what is the ACTOR, who/what is the ACTION. Then choose voice based on what you want the reader to foreground. WATCH for hidden passive — 'It was found that ___' hides the finder. Sometimes that's deliberate; sometimes it's evasion. The writer chooses.

• Argumentative-writing default. Reader sees who's doing what.

  model ACTIVE. Subject (Adichie, actor) + verb (integrates, action) + object (anecdote with cultural observation, acted-upon). Effect: emphasizes Adichie as the agent of integration.

  prompt Identify the voice: 'Adichie integrates anecdote with cultural observation.'
• Same propositional content; different rhetorical emphasis. The writer chooses based on what to foreground.

  model PASSIVE. Subject (anecdote and cultural observation, acted-upon) + be-verb (are) + past participle (integrated) + by-phrase (by Adichie). Effect: emphasizes the integration; de-emphasizes Adichie as agent.

  prompt Identify the voice: 'Anecdote and cultural observation are integrated by Adichie.'
• Scientific writing legitimately uses passive. Don't 'fix' this — it's the right choice for the register.

  model PASSIVE throughout. Effect: scientific procedure where the actor (technician) is irrelevant to the report.

  prompt Identify the voice: 'The mixture was heated to 80°C and stirred for 30 minutes.'
• When an actor is hidden via passive, ask: did the writer mean to hide them? If yes, fine. If no, name them: 'Climate scientists argue that climate change is accelerating.'

  model PASSIVE. Subject 'it' is empty (expletive). Actor (the believer) is omitted. Often a hedge — the writer doesn't name who believes. Could be a deliberate vagueness, or could be evasion.

  prompt Diagnose this sentence: 'It is believed that climate change is accelerating.'

• Pair-share: transform 'Smith conducted the experiment' from active to passive. Then justify when each is better.
• Cold Call: define active and passive voice.

MG-6 Chart

Active vs. passive voice anchor (CCSS L.8.1.b, L.8.3.a): 2-column card with structural visualization and rhetorical-effect tags. ACTIVE VOICE (left, blue). STRUCTURE: SUBJECT (actor) + VERB (action) + OBJECT (acted-upon). EXAMPLES: 'Smith argues that climate change is accelerating.' / 'The researchers conducted the experiment.' / 'Adichie integrates anecdote with cultural observation.' RHETORICAL EFFECT: emphasizes the ACTOR; clarity; directness. WHEN TO USE: argumentative writing, narrative, when the actor matters. PASSIVE VOICE (right, gold). STRUCTURE: SUBJECT (acted-upon) + 'be' verb + PAST PARTICIPLE + (optional 'by' agent). EXAMPLES: 'The experiment was conducted under controlled conditions.' / 'Climate change is accelerated by human activity.' / 'Anecdote and cultural observation are integrated by Adichie.' RHETORICAL EFFECT: emphasizes the ACTION or RECEIVER; de-emphasizes or hides the ACTOR. WHEN TO USE: scientific writing where the procedure matters more than who did it; when the actor is unknown, irrelevant, or deliberately suppressed; when the patient (receiver) is the focal point. WARNING: passive voice is often OVERUSED in academic writing. Choose deliberately, not by default. Bottom rule: 'Neither voice is inherently better. The writer CHOOSES based on what to foreground.'
