Brain Science & SEL Week 1

This month, we’re exploring the connection between brain chemistry and social-emotional learning. Each week, we’ll focus on a key neurotransmitter and connect it to one of CASEL’s core SEL competencies—bringing science into everyday classroom practice. When we understand what’s happening in the brain, we’re better equipped to support how students feel, think, and learn.

Self-awareness is the ability to recognize and understand our emotions, values, and strengths. It’s like having an eagle’s perspective—seeing clearly what’s happening within us in real time.

But most of the time, we’re not operating from that perspective.

Emotional reactions are often fast and visceral. We feel them in our bodies before we can make sense of them in our minds. A thought, a memory, or a moment can trigger a cascade of sensations—our heart rate shifts, our muscles tighten, our mood changes—before we even realize what’s happening.

This is where brain chemistry comes in.

Neurotransmitters like dopamine, serotonin, and norepinephrine are constantly at work, shaping how we feel, focus, and respond. When we’re overwhelmed, these systems can pull us into reactivity. When they’re balanced, they support clarity and reflection.

Self-awareness begins when we learn to notice these internal shifts as they happen.

Think of awareness like turning on the lights.

Without it, we react automatically. With it, we can pause, notice, and choose.

Awareness helps us recognize what we’re feeling, thinking, and sensing in our bodies. Past experiences often shape these patterns, but they’re not fixed. Through neuroplasticity, we can build new patterns of attention and response—strengthening our capacity to notice before we react.

Beneath our thoughts and emotions live our values—our internal compass.

Values shape how we interpret the world and guide how we show up in it. They are often inherited or absorbed from our families and environments, operating quietly in the background of our decisions and behaviors.

But self-awareness invites us to ask:

• Are these my values?
• Do they align with who I am becoming?

When our actions align with our values, we experience greater clarity, integrity, and emotional balance. When they don’t, we often feel tension or disconnection.

Like the foundation of a house, our values provide structure and stability—and they can be strengthened and refined over time.

Self-awareness grows through reflection and intentional practice.

Try this short values practice with your students:
From the list below, choose three values that resonate most with who you are and how you want to show up:

Kindness, Empathy, Integrity, Resilience, Curiosity, Respect, Responsibility, Courage, Gratitude, Service

Next, reflect and discuss as a class:

• Why does this value matter to me?
• When do I live this value? What actions reflect it?
• When I drift from this value, how do I behave? How does it feel?

Now, try this Affirmation Practice:

Today I will live (insert value) by choosing to (insert action).

Small, repeated moments of reflection strengthen self-awareness over time—helping the brain build more aligned pathways for thinking, feeling, and being.
