Lesson 1: Introduction: issues & debates in psychology

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about issues & debates in psychology. Then check against the key terms: Psychology Exam Tips. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: Psychology Exam Tips.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: issues & debates in psychology. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Psychology because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: Explain the nature-nurture debate and evaluate whether behaviour is determined by nature or nurture.

Plenary (5 minutes)

Your student states one thing they learned and one question they still have about issues & debates in psychology.

Lesson 2: Core Concepts: issues & debates in psychology

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on issues & debates in psychology. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Nature vs nurture: nature argues behaviour is determined by inherited genes and biology; nurture argues behaviour is determined by experience and environment. Modern view: interactionism - both contribute. Epigenetics shows environmental factors can switch genes on/off, demonstrating that nature and nurture interact.
Key Fact: Free will vs determinism: free will argues people have conscious control over their choices; determinism argues behaviour is caused by factors beyond our control. Biological determinism (genes/neurochemistry), environmental determinism (conditioning), and psychic determinism (unconscious drives). Soft determinism (Bandura): some freedom within determined constraints.
Key Fact: Reductionism vs holism: reductionism explains behaviour by breaking it down into simpler components (biological reductionism: behaviour = brain chemistry). Holism argues the whole is greater than the sum of parts - behaviour must be understood as an integrated system. Reductionism is scientific but oversimplifies; holism is comprehensive but harder to test.
Key Fact: Ethnocentrism: judging other cultures by the standards of your own. Much research is WEIRD (Western, Educated, Industrialised, Rich, Democratic) and may not generalise. Example: Asch's conformity findings reflect 1950s America; collectivist cultures show higher conformity.
Key Fact: Gender bias: research that treats one gender as the norm (usually male = norm, female = deviation). Alpha bias: exaggerating differences between genders. Beta bias: minimising or ignoring differences. Examples: Kohlberg's moral development theory was based on male participants only; Milgram's study used only male participants but generalised to all people.
Psychology Exam Tips: When discussing issues and debates, always: take a balanced position, use specific examples from research, and acknowledge that most debates are not either/or but exist on a continuum. The interactionist position is usually best supported by evidence.

Practice (10 minutes)

Q: Explain the nature-nurture debate and evaluate whether behaviour is determined by nature or nurture.

Answer: Nature: behaviour is biologically determined (genes, brain, evolution). Evidence: twin studies, universal behaviours. Nurture: behaviour is environmentally determined (learning, culture, upbringing). Evidence: cultural differences, conditioning. Modern interactionism: both contribute - genes provide predispositions, environment triggers or suppresses them. Epigenetics shows environment can alter gene expression.

Your student teaches the key points back to you without looking. Fill any gaps immediately.

Lesson 3: Application: issues & debates in psychology

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: Psychology Exam Tips. Define each in one sentence.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Q1: Explain the nature-nurture debate and evaluate whether behaviour is determined by nature or nurture.

Answer: Nature: behaviour is biologically determined (genes, brain, evolution). Evidence: twin studies, universal behaviours. Nurture: behaviour is environmentally determined (learning, culture, upbringing). Evidence: cultural differences, conditioning. Modern interactionism: both contribute - genes provide predispositions, environment triggers or suppresses them. Epigenetics shows environment can alter gene expression.

Q2: Describe the difference between free will and determinism, giving examples of each from psychological research.

Answer: Free will: people make conscious choices about their behaviour. Supported by: subjective experience of choice, effectiveness of therapies that assume personal agency (CBT). Determinism: behaviour is caused by prior factors. Biological determinism (genes -> behaviour), environmental determinism (conditioning -> behaviour), psychic determinism (unconscious drives). Soft determinism (Bandura): behaviour is influenced but not rigidly determined - we have conscious control within constraints.

Q3: Evaluate whether psychological research suffers from ethnocentric and gender bias, and explain how this can be addressed.

Answer: Ethnocentric bias: Western research dominates and may not generalise (Asch's conformity findings vary by culture; WEIRD samples are not representative). Gender bias: male participants overrepresented (Milgram used only males, Kohlberg's moral stages based on males). Addressing bias: use diverse samples, conduct cross-cultural research, include both genders, be aware of androcentrism (male-centred perspective), and report limitations of sample generalisability.

Extended Answer

Extended question: Full-Mark Response Evaluate whether the nature-nurture debate has been resolved by modern psychology. <div class="

A grade 9 response will: define nature and nurture with evidence for each; explain why the debate is a false dichotomy (interactionism); present epigenetics as evidence for interaction (environment switches genes on/off); discuss the diathesis-stress model (genetic vulnerability + environmental triggers); evaluate using specific examples (depression: genetic predisposition + life events; phobias: biological preparedness + conditioning); conclude: the nature-nurture debate is largely resolved in favour of interactionism - both contribute to all behaviour. The question is no longer whether nature or nurture matters, but HOW they interact. Epigenetics provides the mechanism for this interaction, showing that the old nature-vs-nurture framework is outdated.

Exam Tips: Nature = biology. Nurture = experience. Modern answer: BOTH (interactionism, epigenetics). | Free will = we choose. Determinism = behaviour is caused. Soft determinism = influenced but not rigidly fixed. | Reductionism = break it down (scientific but oversimplified). Holism = see the whole picture (comprehensive but harder to test).
Common Errors: Watch Out! Students often make mistakes here. Wrong: If behaviour is determined by biology and environment, then people cannot be held responsible for their actions. Correct: While determinism suggests behaviour has causes, this does not mean people lack all responsibility. Soft determinism (Bandura) argues we have conscious choice within constraints. The legal system recognises degrees of responsibility (diminished responsibility for mental illness). Free will may be limited rather than absent. Furthermore, understanding the causes of behaviour can INCREASE our ability to change it (e.g. CBT teaches people to challenge determinist thoughts). Determinism explains causes; it doesn't eliminate
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how issues & debates in psychology connects to another Psychology topic you have studied
  • Real-world: research one real-world use or example of issues & debates in psychology
  • Critical: "What are the limitations of the models used in issues & debates in psychology?"
