Unlocking Theories

Overview

In this first lesson of the unit, students are introduced to key psychological theory terms and a starter set of major theories used to explain human behaviour. They will practise defining terms and sorting theories by purpose.

Learning intentions

• WALT understand psychological theories and why they are used to explain human behaviour.
• WALT identify at least three major psychological theories and describe what each aims to explain.
• WALT use appropriate vocabulary to define key terms linked to theories.

Success criteria

• I can define at least 6 key terms related to psychological theories (e.g., theory, hypothesis, behaviour, evidence, perspective, explanation).
• I can identify at least three major psychological theories (e.g., behaviourism, cognitive theory, psychoanalytic theory) and state a brief purpose for each.
• I can compare theories using “what they focus on” and “what evidence they would use” (in general terms).

Curriculum links

• Social Sciences (Year 13): builds inquiry skills for researching and explaining human behaviour using evidence-based perspectives, aligned to NCEA Level 3 History/Research skills (research process, evaluating evidence) as an overall capability mindset.
• Thinking and Participating and Contributing: students use reasoning to categorise information and communicate learning clearly.
• Values: respectful discussion of differing viewpoints (how theories offer different explanations).

Lesson structure (60 minutes)

1. 0–5 min · Welcome + question prompt. Teacher shares a short scenario (e.g., “Why do people procrastinate when deadlines are close?”) and asks what a psychologist might try to explain. Students record first thoughts in a notebook.

2. 5–15 min · Direct teach: what a theory is. Teacher explains the purpose of psychological theories, distinguishing “theory” from “opinion”, and introduces key vocabulary (theory, hypothesis, evidence, perspective, behaviour, explanation). Students complete a quick “definition-match” worksheet individually, then check with a partner.

3. 15–25 min · Gallery walk: three major theories (starter set). Teacher places three mini-posters around the room (Behaviourism, Cognitive theory, Psychoanalytic theory). Students move in groups of 3–4, spending 2–3 minutes at each poster to extract: “What it focuses on” and “What it tries to explain.” Students add notes to a three-column template.

4. 25–35 min · Guided comparison tool. Teacher models one comparison row (e.g., “Behaviourism focuses on observable behaviour; explains behaviour through learning/conditioning; would look for evidence like experiments.”). Students complete the remaining rows for the three theories using sentence starters.

5. 35–48 min · Sorting activity: evidence and purpose. Teacher gives mixed “cards” (short statements like “focuses on observable actions”, “focuses on mental processes”, “focuses on unconscious influences”, and “would use experiments/observations/interviews in general terms”). Students sort cards into the correct theory category and justify each placement with one phrase using their vocabulary (e.g., “This theory perspective explains behaviour by…”).

6. 48–55 min · Whole-class sense-making. Teacher facilitates a brief discussion: “How can different theories lead to different explanations of the same behaviour?” Students contribute one example and identify one key strength of using theories to understand people.

7. 55–60 min · Exit ticket + teacher check. Students answer: (1) Define theory in their own words, (2) Name three theories and one focus for each, (3) Write one key difference between any two theories. Teacher reviews for next-step grouping.

Resources

• Scenario prompt card (procrastination or another relatable behaviour)
• Definition-match worksheet (key vocabulary + simple definitions)
• Three theory mini-posters (Behaviourism, Cognitive theory, Psychoanalytic theory)
• Three-column comparison template
• Sentence starters strip (e.g., “This theory focuses on…”, “It explains behaviour by…”, “Evidence might include…”)
• Theory sorting cards (focus statements + general evidence/purpose statements)
• Exit ticket slips
• Coloured highlighters for visual grouping

Assessment

• Formative checks: definition-match accuracy and partner correction during early task
• Formative checks: teacher observes group notes during gallery walk and circulates during comparison tool completion
• Exit ticket to confirm students can define key terms and identify at least three theories with a clear focus statement

Differentiation

• Provide visuals: mini-posters with colour-coded theory labels and icons for “focus” areas (behaviour/brain/thoughts/unconscious)
• Provide summaries: sentence starters and a simplified comparison table with word banks for ELL students
• Scaffold thinking: offer a worked example row before independent comparison
• Support and extension options:
• Support: teacher-led small group for completing the comparison rows using prompted choices (“This theory focuses on…”)
• Extension: challenge students to add a “possible research method” card that best fits each theory (e.g., observation/experiment/interview) and justify briefly

Assessment criteria for this lesson (student-facing)

• I can define key vocabulary clearly enough to explain psychological theories.
• I can identify and describe at least three theories and their purpose in explaining behaviour.
• I can compare theories using evidence language (e.g., what kind of information would support the explanation).
