Lesson Plan: Understanding Research in Psychology
Lesson Duration:
30 Minutes
Academic Subject:
Psychology
Topic:
Research - Correlation vs Causation
Objectives:
By the end of this lesson, students will be able to:
- Define correlation and causation in the context of psychological research.
- Differentiate between correlation and causation with examples.
- Explain the significance of understanding the difference in psychological studies.
Materials Needed:
- Whiteboard and markers
- Projector and screen for presentations
- Handouts summarizing the key points
- Access to online research articles (optional)
Lesson Outline:
Introduction (5 Minutes)
- Begin the lesson with a brief overview of research in psychology, emphasizing its importance.
- Introduce the central topic: the difference between correlation and causation.
- Pose the question: "Can correlation imply causation?" to engage students.
Direct Instruction (10 Minutes)
-
Definition of Correlation:
- Explain that correlation refers to a statistical relationship between two variables. A positive correlation means that as one variable increases, the other also increases. A negative correlation means that as one variable increases, the other decreases.
-
Definition of Causation:
- Define causation as a relationship where one variable directly influences or causes a change in another variable.
-
Key Differences:
- Illustrate the primary differences through a Venn diagram on the board. Emphasize that while correlated variables may move together, it does not necessarily mean one causes the other.
-
Examples:
- Present real-world examples:
- Correlation: Ice cream sales increasing in summer months correlating with increased drownings.
- Causation: Smoking causing lung cancer.
Visual Aids:
- The image of a Venn diagram illustrating correlation and causation, showing examples of each.
- The image of two graphs displaying a positive correlation and a causation example separately.
Interactive Activity (10 Minutes)
- Group Discussion:
- Divide students into small groups and assign each group a scenario (e.g., "More hours spent studying correlates with higher grades").
- Ask them to determine whether the relationship is correlational or causal and to justify their reasoning.
- Encourage groups to present their findings to the class.
Conclusion and Summary (5 Minutes)
Assessment:
- Hand out a short quiz or a reflection paper for students to complete as a formative assessment of their understanding of correlation versus causation.
Additional Discussion Points (if time permits):
- Discuss the implications of misinterpreting correlation as causation in psychological research and real-world decision-making.
- Examine famous research studies that provide examples of both correlation and causation, such as the relationship between stress and health outcomes.
Images for Use:
The image of a Venn diagram illustrating correlation and causation, showing examples of each.
The image of two graphs displaying a positive correlation and a causation example separately.
The image of students engaged in a group discussion, sharing ideas with each other enthusiastically.
Closing
Thank students for their participation and encourage them to reflect on the importance of understanding these concepts in both academic and everyday contexts. Remind them that skill in interpreting these different kinds of relationships is a critical aspect of psychological research.
