  • IBDP Psychology and peace negotiations

    Understanding conflict is important for peace in Ukraine. Two elements of the IBDP Psychology course would help both Ukraine and Russia achieve peace – if that’s what they want.

    Peace tnrough IBDP Psychology

    If peace is the goal, Sherif et al. (1957)’s The Robbers Cave Study and Henri Tajfel’s Social Identity Theory offer hope.

    In the Robbers Cave Study, Sherif divided teenage boys at a summer camp into two competing groups. Initially, they bonded in their own groups. When competition was introduced, hostility erupted between the groups. Tbe conflict was resolved when the boys were given superordinate goals – to fix a leaking water tank. Working together, the mete act of required cooperation against a shared problem, turned the rival groups into allies.

    Henri Tajfel’s Social Identity Theory (SIT) explains how people categorize themselves into groups, leading to an “us vs. them” state – emphasis on the ‘versus’. The perceived difference triggers conflict. But SIT also shows that group identities can be reshaped. When people see themselves as part of a larger, inclusive group, intergroup conflict decreases, cooperation is possible and peace between previously warring groups can occur.

    Applying this knowledge about human behavior can lead to peace in Ukraine and Russia. It’s about creating shared goals and identities. The Orthodox church leaders in Russia and Ukraine could play a role here. Instead of reinforcing divisions, the church leaders could highlight common interests: we are more alike than different. Economic leaders such as the IMF could show that both countries, working together through a Free Trade Agreement could achieve economic growth and, more importantly, economic development.

    Of course, this presupposes that both Ukraine and Russia want peace.

  • Sleep – the overlooked health treatment

    Sleep – the overlooked health treatment

    As psychology teachers, we’re often at the front and centre of mental health discussions – with students and also with colleagues. We teach our students about the biological, cognitive, and social explanations of disorders, the effectiveness of SSRIs, and the transformative power of CBT. And yet, one of the simplest and most effective interventions remains woefully underemphasized: adequate sleep.

    There is a mountain of credible, published research highlighting just how significant sleep is to emotional regulation. We have compelling evidence showing that poor sleep isn’t just a symptom of anxiety or depression, it is often the primary cause.

    The relationship between sleep and mental health is bidirectional, creating a vicious cycle: insufficient sleep heightens emotional reactivity, disrupts rational thought processes, and increases vulnerability to stress, making individuals more prone to anxiety and depression.

    One night of sleep deprivation leads to a significant spike in anxiety and low mood the following morning. Chronic, ie longer term, sleeplessness makes everyday events feel more negative, reinforcing a bleak outlook on life. Research shows that individuals suffering from insomnia are at twice the risk of developing anxiety or depression compared to those who sleep well.

    The evidence is compelling. Sleep deprivation impairs the prefrontal cortex, the brain’s emotional regulator, weakening its connection to the amygdala, which governs fear and emotional responses. This disruption makes individuals more emotionally volatile, prone to misperceiving neutral events as negative, and more likely to spiral into stress and mood disorders.

    As educators, we must recognize the immense potential of sleep education as a preventative mental health strategy. A CAS project that focuses on sleep awareness could help students (and colleagues) track their sleep, analyze its effects on mood and cognitive function, and share findings with peers.

    Getting sufficient sleep is not about school starting later or school providing quiet spaces for rest. It’s about teaching students, their parents, and colleagues that the simplest treatment (and prevention) strategy relating to the most common mental health issues of anxiety and depression is getting sufficient sleep. In general we all need 8-9 hours of sleep, so we must go to bed more than 8-9 hours before the required wake-up time because we need about half an hour to ‘fall asleep’. We all need to be in bed, light off and phone off around half an hour before the sleep time.

    Ultimately, if there is one piece of mental health advice we can give our students—and even our colleagues—it is this: Prioritize sleep because it is the foundation of emotional resilience, cognitive function, and overall well-being.

    I seldom see anxious cats.

  • The new DP Psychology course – homework revision questions

    IB Diploma Psychology – Homework revision questions is designed to be the perfect companion to the IB Diploma Psychology course, helping students build strong, well-organized responses while reinforcing key concepts. By integrating structured practice with the course content, it encourages gradual, steady learning—the most effective way to truly understand the new IBDP Psychology syllabus.

    I will be using this book for regular homework tasks, where students write structured responses that can be peer-marked or self-assessed using provided mark schemes. Homework seems to work best when it is regular – supporting every lesson – perhaps even think of it as practice. The homework ensures continuous engagement with the syllabus, while also developing the habit of clear, well-constructed writing and neat presentation—crucial skills for an exam that is still written with pens and paper.

    Research shows that slow and steady learning works best. By routinely summarizing and applying class lessons, students strengthen their understanding over time, rather than cramming at the last minute. The IB exams don’t test rote memorization but rather how well students apply psychological concepts to new contexts. Regular, structured homework ensures they develop this skill naturally, making exam preparation manageable and stress-free.

    By using this workbook throughout the two-year course, students will gradually master the subject, ensuring they are confident, prepared, and capable of tackling any exam question that comes their way.

  • IBDP Psychology: Lesson One

    IBDP Psychology: Lesson One

    I’ve been thinking about my first few lessons for next year’s new IBDP Psychology course. I want to make it immediately relevant and meaningful to the students. What better way to do that than by using psychology itself to explain how they will learn best?

    Neuroplasticity: Why simple repetition works.

    A robust psychology theory is neuroplasticity, the brain’s ability to change and adapt based on experience. This is one of the topics in the biological approach and it ties directly into how students develop their skills and retain knowledge in all of their IBDP classes. Through repetition and rehearsal, neural pathways are strengthened—a process known as myelination. When students rewrite notes, engage in retrieval practice, or explain concepts to others, they are literally strengthening the neural networks to retain information.

    In my first lesson, I’ll show students how scientifically-backed learning strategies—like spaced repetition, active recall, and scaffolding—aren’t just things we suggest as teachers, but are grounded in psychological research. If they understand why these strategies work, they’ll be more likely to use them.

    Causality – the cause of learning

    This elegantly connects to one of psychology’s core concepts: Causality. There is a clear cause-and-effect process at play. If students consistently engage in structured note-taking and revision (cause), they strengthen their neural pathways (effect), leading to improved retention and recall. This lesson will help students recognize that their academic success isn’t just about talent or intelligence—it’s about how they use their brains effectively.

    Starting the course this way accomplishes two things:

    1. It immediately makes the course feel relevant because the students will see that psychology isn’t just about research studies but about their own experiences, habits, and learning processes.
    2. It gives them a toolkit for success. If they embrace evidence-based study strategies from day one, they’re more likely to perform well not just in psychology, but in all their IBDP subjects.

    I want my students to leave their first Psychology lesson not just excited about Psychology, but empowered by it.
