Introduction to Your Class Practicals

Welcome to one of the most hands-on parts of your IB Psychology journey! In this course, you don't just read about psychology; you "do" psychology. Throughout the program, you are required to complete a minimum of four class practicals—one for each of the four contexts. These aren't just for practice; they are directly examined in Paper 2, Section A.

Think of these practicals as your "rehearsal" for the Internal Assessment (IA). Because you have actually conducted these studies, you will have a unique, first-hand perspective when answering exam questions about them. Don't worry if your results weren't perfect—in psychology, we learn just as much from what goes wrong as from what goes right!

The Four Required Practicals: A Snapshot

For Paper 2, you must be prepared to answer questions on any of the four practicals you conducted in class. Each practical uses a specific research method and is tied to a specific context. Here is the breakdown of what you should have in your "toolkit":

  • Health and well-being: Conducted using an interview (structured, semi-structured, or focus group).
    • Sample size: At least \(n = 1\) for individual interviews or \(n = 3\) to \(8\) for a focus group.
  • Human development: Conducted using an observation (naturalistic or controlled, overt or covert, participant or non-participant).
    • Sample size: At least \(n = 1\) participant.
  • Human relationships: Conducted using a survey/questionnaire.
    • Sample size: At least \(n = 10\) participants.
  • Learning and cognition: Conducted using an experiment (true or quasi-experiment).
    • Sample size: At least \(n = 5\) participants.

Quick Tip: Keep a "Practical Logbook." After each activity, write down exactly what you did, who your participants were, and any challenges you faced. This will be your best revision guide for Paper 2!

Understanding Paper 2, Section A

In Section A of Paper 2, you will face four compulsory questions. These questions focus specifically on the practicals listed above. Unlike other parts of the exam where you might write about famous studies like Milgram or Loftus, here you are the lead researcher. You are writing about your work.

What will the questions ask?

The questions are designed to test your knowledge, application, and evaluation skills (AO1, AO2, and AO3). You might be asked to:

  • Describe the method or sampling technique you used.
  • Explain why a specific method was appropriate for a context (e.g., "Why use an interview to study health and well-being?").
  • Justify the ethical considerations you took into account.
  • Evaluate your practical using the six core concepts.

Did you know? Your Internal Assessment (IA) is a research proposal. It must use one of the four methods you practiced in these class practicals. Mastering these now makes your IA much easier later!

Linking Practicals to the Six Concepts

The IB Psychology course is built around six big ideas. When you reflect on your practicals for the exam, try to view them through these "lenses":

  1. Bias: Did your own expectations influence how you recorded observations? Did your survey questions "lead" the participants to answer a certain way?
  2. Causality: In your experiment for Learning and cognition, can you truly say the independent variable caused the change in the dependent variable?
  3. Change: Did your participants' behavior change because they knew they were being observed (the Hawthorne effect)?
  4. Measurement: How did you turn a complex idea (like "well-being" or "memory") into a number or a category? Was your tool accurate?
  5. Perspective: How might a different researcher interpret your interview data? Would a sociocultural approach explain your findings differently than a biological one?
  6. Responsibility: How did you protect your participants? Did you ensure informed consent and anonymity?

Analogy: Imagine you are a judge in a talent show. Bias is if you prefer singers over dancers; Measurement is the scorecard you use; and Responsibility is making sure the stage is safe for the performers.

Step-by-Step Exam Preparation

To succeed in Paper 2 Section A, follow these steps for each of your four practicals:

1. Know your "What and Why"

Be ready to state your aim (what you wanted to find out) and your procedure. Be specific! If you did an experiment, identify your variables.

2. Reflect on the Sample

Why did you choose that specific population of interest? For your survey on Human relationships, why was \(n = 10\) the minimum, and how did that small size affect your results?

3. Identify the "Hiccups"

Every practical has limitations. Maybe the room was too noisy during your Learning and cognition experiment, or your Human development observation participant acted shy. Identifying these is not a sign of failure—it’s a sign of a good psychologist!

4. Connect to Research Methodology

Use the correct terminology. Don't just say "we watched them"; say "we conducted a naturalistic, non-participant observation." This shows the examiner you have mastered the research methodology content strand.

Common Mistakes to Avoid

  • Mixing up contexts and methods: Remember, you cannot use a survey for the Learning and cognition practical; it must be an experiment.
  • Being too vague: Instead of saying "we used some people," say "we used a purposive sample of 5 students."
  • Ignoring Ethics: Always mention how you acted with responsibility toward your participants.
  • Forgetting the "Proposal" nature of the IA: Remember that while these practicals are "done," your IA is a proposal for a study you plan to do. Don't confuse the two in your mind!

Key Takeaways

Quick Review:

  • Paper 2 Section A has 4 compulsory questions on your class practicals.
  • You must do one practical for each context: Health and well-being (Interview), Human development (Observation), Human relationships (Survey), and Learning and cognition (Experiment).
  • Focus on Research Methodology and the six concepts (Bias, Causality, Change, Measurement, Perspective, Responsibility) when answering.
  • The minimum sample sizes are \(n = 1\) (interview/observation), \(n = 10\) (survey), and \(n = 5\) (experiment).

Don't worry if this seems like a lot to remember! By the time you get to the exam, you will have lived through these practicals, making the details much easier to recall than if you were just reading them from a book.
