Atomic Habits assignment, the first year
When we – Yosup Joo and I – designed the Introduction to Behavioral Neuroscience course, we wanted it to be more than just memorizing vocabulary… which is what the AP Psychology course had been, largely. We wanted students to live the concepts they were studying. That's how I ended up assigning James Clear's "Atomic Habits" as a semester-long project — not just to read, but to implement.
The premise was simple: over 18 weeks, students would select, develop, and maintain a single habit while connecting their experience to neuroscience principles. What unfolded was far more complex and revealing than I anticipated.
I divided the project into six parts, mirroring Clear's book:
Introduction & Part One: Students reflected on who they are versus who they want to become
Part Two - Make it Obvious: Implementation intentions and environmental design
Part Three - Make it Attractive: Temptation bundling and community support
Part Four - Make it Easy: The two-minute rule and friction reduction
Part Five - Make it Satisfying: Tracking and accountability
Part Six - Advanced Strategies: Personality alignment and long-term sustainability
Each submission required 3-4 paragraph responses, encouraging moderate reflection rather than surface-level reporting.
Linked here are the six assignments.
What the Students Taught Me
The Universal Struggle with Technology
Nearly 70% of my students identified procrastination as their primary challenge, with phone addiction as the universal villain. One student wrote with striking honesty: "Apps like Opal to reduce screen time are too easy to override, just like Apple's built-in time limit." This wasn't just a side issue—it was the issue that undermined nearly every other habit attempt.
The Power of Identity-Based Change
Students who grasped Clear's concept of identity-based habits showed remarkable insight. One wrote: "I want to become a person who is confident, kind, and resilient...someone who stays calm under pressure, trusts themselves." They weren't just trying to do things differently; they were trying to become someone different.
The Emotional Undercurrent
What surprised me most was the vulnerability in their responses. Behind the academic language were stories of:
Burnout: "I have been working hard for most of my entire life...but now I just feel so tired of it all"
Social anxiety: "I rarely raise my hand, even when I know the answer"
Self-doubt: "I frequently doubt my instincts and question whether I am making the right choices"
This wasn't just a habit-formation exercise; it was a window into their struggles with life, identity, and growing up.
For the complete analysis of student responses across all six assignments, see this summary by Claude.
This concept resonated universally. Students discovered that "the hardest part is honestly just starting," and the two-minute rule made that starting achievable. One student noted: "Usually, once I begin, I naturally keep writing more."
Students who reorganized their physical spaces saw immediate results. Simple changes—moving phone chargers away from beds, placing yoga mats beside their beds, reorganizing kitchens for meal prep—created powerful behavioral shifts.
The "Never Miss Twice" Rule
This principle was transformative for many. As one student reflected: "This rule honestly changed how I deal with failure. Before, if I slipped up, even once, I'd feel like I ruined everything and just stop trying."
Overly Ambitious Initial Goals
Many students chose habits that were too complex or time-consuming. They needed more guidance on starting small and scaling up gradually.
Weak Neuroscience Integration
While students engaged deeply with behavior change, most didn't naturally connect their experiences to course concepts about neuroplasticity, dopamine pathways, or basal ganglia function. This was a missed opportunity for deeper learning.
Consistency crumbled on weekends for many students. Different schedules, social pressures, and the absence of weekday structure created a recurring failure point.
Despite Clear's emphasis on community, most students worked in isolation. Those who found accountability partners succeeded more consistently, suggesting we need better peer support structures.
Based on this year's experience, here's how I'll improve the assignment:
1. Mandatory Phone Management Module
Since technology addiction affected everyone, I'll add a dedicated class lesson on digital wellness before Part Two, with required phone management strategies regardless of chosen habits.
2. Structured Habit Selection
A "Habit Feasibility Checklist" (Can it be done in under 10 minutes? Do you already have the resources?)
Categories with difficulty ratings
Required 2-minute versions for the first two weeks
3. Neuroscience Integration Checkpoints
Each submission will include explicit prompts connecting experiences to:
Habit loops and basal ganglia (Part 2)
Dopamine and reward systems (Part 3)
Neuroplasticity and repetition (Part 4)
4. Built-in Accountability Systems
Mandatory habit buddy partnerships
Weekly micro-check-ins (2-3 questions)
A class discussion board for sharing wins and strategies
5. Weekend-Specific Planning
Students will create separate implementation intentions for weekdays versus weekends, acknowledging these as different contexts requiring different strategies.
6. Formal "Habit Pivot" Protocol
After Week 4, students can officially change their habit with structured reflection on why the change is necessary—normalizing adaptation rather than viewing it as failure.
Running the assignment and every student submission through Claude, a more complete (and thorough recommendation) was generated; that's available here.
This assignment revealed something profound: behavior change isn't just about willpower or technique—it's about identity, community, and self-compassion. Students learned that small changes compound, that environment shapes behavior, and that failure is data, not defeat.
One student's reflection captures the transformation: "By simply doing that, I've started off unconventionally, but at least I started." That's the real lesson—not perfection, but progress. I should know this! As a distance runner, I regularly tell myself – and any beginning runner who talks to me about it – that "running never gets easier; you just get better at it."
As educators, we often focus on content delivery and assessment. This project reminded me that sometimes the most powerful learning happens when students apply concepts to their own lives. The neuroscience they'll remember won't just be the textbook definitions but the lived experience of rewiring their own brains, one small habit at a time.
Next year's students will benefit from this year's pioneers. I'll share anonymized success stories, create templates based on what worked, and address common pitfalls upfront. But I'll also preserve the space for vulnerability and self-discovery that made this assignment so powerful.
Because ultimately, this isn't just about building better habits—it's about helping students become the people they want to be, with neuroscience as both the map and the territory.
