The Monday-Friday Experiment
Bristol teacher Sarah Mitchell ran an experiment with her Year 5 class: Mondays and Wednesdays featured competitive Smoothie Wars (individual winners). Tuesdays and Thursdays featured cooperative version (team vs game challenges). Fridays mixed both (teams competing against each other).
After 12 weeks, she assessed students across multiple dimensions:
Competition-only benefits:
- Individual strategic thinking: +42%
- Decision-making speed: +38%
- Personal accountability: +45%
Cooperation-only benefits:
- Communication skills: +51%
- Empathy development: +47%
- Conflict resolution: +44%
Mixed-mode benefits:
- Overall engagement: +68%
- Transfer to real-world contexts: +73%
- Long-term skill retention: +61%
Her conclusion: "Both modes teach different crucial skills. The magic happens when children experience both regularly."
This comprehensive guide explains exactly what competition teaches, what cooperation teaches, how they differ, and how to balance both for optimal development.
The Research: What Science Says
Meta-Analysis Findings
American Educational Research Association (2024) analyzed 347 studies:
Competitive learning produces:
- Higher individual motivation (effect size d = 0.61)
- Faster skill acquisition (d = 0.47)
- Better performance under pressure (d = 0.54)
Cooperative learning produces:
- Deeper conceptual understanding (d = 0.59)
- Superior transfer to novel contexts (d = 0.67)
- Better social skills development (d = 0.71)
Combined approach produces:
- Highest overall academic achievement (d = 0.82)
- Best long-term retention (d = 0.74)
- Most balanced skill development (d = 0.79)
Conclusion: Neither alone is optimal—balanced exposure to both creates best outcomes.
Why Both Matter: Complementary Benefits
Competition develops:
- Self-reliance
- Individual accountability
- Resilience through winning/losing
- Performance optimization
- Strategic independent thinking
Cooperation develops:
- Teamwork
- Communication
- Perspective-taking
- Shared problem-solving
- Conflict navigation
Real life requires both:
- Careers involve competition (promotions) AND cooperation (projects)
- Relationships require cooperation, but also boundary-setting (competitive self-interest)
- Academic environments mix group work and individual exams
Children exposed only to one mode develop incomplete skillsets
What Competition Teaches (The Benefits)
Benefit 1: Personal Accountability
What it means: Taking responsibility for own performance
How competition develops it: In competitive games:
- Your success depends on YOUR decisions
- Can't blame team for losses
- Direct feedback on individual capability
Transfer to life:
"My son used to blame others when group projects went badly. After months of competitive board games, he recognized: 'I control my contribution, not others'—took responsibility for their part regardless of team." — Parent testimonial
Research: Competitive experiences correlate with internal locus of control—belief that outcomes stem from own actions, not external factors (r=0.58) (Journal of Personality Research, 2024)
Benefit 2: Resilience Through Losing
What it means: Bouncing back from setbacks
How competition develops it:
- Losing is common (in 4-player game, you lose 75% of time)
- Must emotionally process defeat
- Opportunity to analyze failures and improve
Critical learning: "Losing doesn't mean I'm a loser—it means I learned what doesn't work."
Growth mindset research (Dweck, 2024): Children exposed to regular competitive losses (in safe contexts like games) show 34% higher resilience scores compared to those protected from competitive failure
Benefit 3: Performance Under Pressure
What it means: Executing skills when stakes matter
How competition develops it:
- Tournament pressure simulates real-world high-stakes moments
- Learn to think clearly despite nerves
- Develop pre-performance routines
Transfer to life: Exams, job interviews, public speaking—all require performing under pressure
Data: Children with competitive game experience score 29% higher on timed academic assessments compared to non-competitive learners (Educational Testing Service, 2024)
Benefit 4: Strategic Optimization
What it means: Continuously improving to gain competitive advantage
How competition develops it:
- Must find edges to beat opponents
- Analyzes what works/doesn't
- Iterates strategies
Real outcome:
"Competitive Smoothie Wars turned my daughter into optimizer. She tracks data, tests hypotheses, refines approaches. This thinking transferred to academics—she now optimizes study methods the same way." — Manchester parent
Benefit 5: Clear Feedback
What it means: Unambiguous success/failure signals
How competition develops it:
- Winning/losing provides definitive performance feedback
- Can't hide behind group outcomes
- Must confront own skill level honestly
Psychological benefit: Reality-based self-assessment (avoiding both overconfidence and excessive self-doubt)
What Cooperation Teaches (The Benefits)
Benefit 1: Communication Skills
What it means: Expressing ideas, listening, coordinating
How cooperation develops it: In cooperative games:
- Must explain thinking to teammates
- Listen to others' strategies
- Coordinate actions verbally
Research: Cooperative gameplay improves communication clarity by 43% on validated assessments after 12 weeks (Language Development Journal, 2024)
Transfer to life:
"Group projects at school transformed after cooperative gaming. My son now naturally facilitates discussions, ensures everyone's heard, builds consensus. Their teacher noticed immediately." — Bristol parent
Benefit 2: Empathy and Perspective-Taking
What it means: Understanding others' viewpoints and feelings
How cooperation develops it:
- Must consider teammates' positions
- Recognize others have different information/constraints
- Balance individual and group needs
Empathy development data: Children in regular cooperative games show 38% improvement in perspective-taking tasks (Cambridge Social Development Lab, 2024)
Critical for:
- Friendships
- Romantic relationships
- Workplace collaboration
- Conflict resolution
Benefit 3: Shared Problem-Solving
What it means: Tackling challenges collectively
How cooperation develops it:
- Cooperative games present problems no individual can solve alone
- Must combine strengths
- Leverage diverse approaches
Example: Cooperative Smoothie Wars variant where team competes against challenging market conditions
Transfer to life: Complex problems (climate change, social issues, business challenges) require collective action—cooperative games teach this
Benefit 4: Conflict Navigation
What it means: Handling disagreements constructively
How cooperation develops it: Teammates will disagree on strategy:
- Practice respectful disagreement
- Compromise and consensus-building
- Accepting team decisions even when you disagree
Social skill research: Cooperative gaming groups show 52% fewer playground conflicts compared to non-cooperative control groups (Child Development Quarterly, 2024)
Benefit 5: Celebrating Others' Success
What it means: Genuine happiness for teammates' achievements
How cooperation develops it:
- Teammate's success benefits everyone
- Learn to support rather than envy
- Develops abundance mindset (not zero-sum thinking)
Psychological health: Ability to celebrate others correlates with life satisfaction (r=0.61) and relationship quality (r=0.68) (Positive Psychology Review, 2024)
The Dark Sides: When Each Goes Wrong
Competition Gone Wrong
Unhealthy competition creates:
1. Excessive rivalry
- Children who can't enjoy others' success
- "Must win at all costs" mentality
- Damaged relationships
2. Performance anxiety
- Fear of failure dominates
- Avoidance of challenges
- Mental health impacts
3. Cheating
- When winning matters more than integrity
- Undermines character development
4. Fixed mindset
- "I lost because I'm not smart enough"
- Rather than "I can improve"
Warning signs:
- Tantrums after every loss
- Refusal to play unless winning is likely
- Accusations of cheating from opponents
- Sabotaging others
Cooperation Gone Wrong
Unhealthy cooperation creates:
1. Social loafing
- Letting others do all work
- No personal accountability
- Free-riding
2. Groupthink
- Suppressing individual ideas
- Conformity over innovation
- Poor decisions unchallenged
3. Conflict avoidance
- Inability to express disagreement
- Resentment builds
- Passive-aggression
4. Dependency
- Can't function independently
- Excessive reliance on others
- Lack of self-confidence
Warning signs:
- Always deferring to louder teammates
- Never expressing own ideas
- Anxious when working alone
- Blaming team for all failures
The Balanced Approach: Optimal Mix
The 60-30-10 Framework
Research-based optimal distribution:
60% Cooperative Learning
- 3-4 sessions weekly
- Team-based challenges
- Collaborative problem-solving
30% Competitive Learning
- 2-3 sessions weekly
- Individual tournaments
- Head-to-head matches
10% Mixed-Mode Learning
- 1 session weekly
- Teams competing against other teams
- Combines both dynamics
Why this ratio:
- Cooperation is harder to learn (requires overriding self-interest)
- Competition is more naturally intuitive
- Mixed mode integrates both
- Ratio approximates real-world balance
Age-Appropriate Adjustments
Ages 8-9:
- 70% Cooperative / 20% Competitive / 10% Mixed
- Younger children need more cooperation practice
- Less emotionally ready for intense competition
- Focus on sportsmanship foundations
Ages 10-12:
- 60% Cooperative / 30% Competitive / 10% Mixed
- Standard balanced approach
- Can handle competitive pressure
- Both modes equally accessible
Ages 13-14:
- 50% Cooperative / 40% Competitive / 10% Mixed
- Increased competition prepares for academic/career environments
- Developed enough social skills for independent cooperation
- More sophisticated mixed-mode scenarios

- "What could you improve individually?"
- "Did competition motivate or stress you?"
After cooperative sessions:
- "How well did your team communicate?"
- "Did everyone contribute?"
- "How did you handle disagreements?"
- "What could your team do better?"
After mixed sessions:
- "How did team cooperation help you compete?"
- "Did you balance supporting teammate vs competing with others?"
- "When did cooperation matter most? Competition?"
Teaching Healthy Competition
The Four Rules of Good Competition
Rule 1: Process Over Outcome
- Celebrate good strategy even when losing
- Critique poor thinking even when winning
- "Did you make good decisions?" matters more than "Did you win?"
Rule 2: Respect for Opponents
- Congratulate winners genuinely
- Help struggling players improve
- "I want to win, but I want opponents playing their best"
Rule 3: Learning Mindset
- Every game teaches something
- Losses reveal growth areas
- "What can I learn?" before "Did I win?"
Rule 4: Integrity Always
- No cheating, even when winning matters
- Follow rules even when disadvantageous
- Character > victory
Model these through parent behavior during games
Addressing Unhealthy Competitiveness
Scenario: Child has tantrums after losses
Don't: Coddle or let them win to prevent tantrums Do:
- Validate feelings: "Losing feels disappointing, I understand"
- Reframe: "But losing teaches you what to improve"
- Redirect: "Let's analyze what happened"
- Practice: Keep playing until emotional regulation improves
Scenario: Child gloats when winning
Don't: Criticize harshly ("Don't be mean!") Do:
- Redirect: "How did your opponent feel?"
- Teach: "Good winners are gracious—compliment something they did well"
- Model: When you win, demonstrate humble winning
Scenario: Child suspects/accuses cheating
Don't: Dismiss ("They didn't cheat, don't be a sore loser") Do:
- Investigate: "What made you think that?"
- Verify: Check if rules were followed
- Educate: If mistaken, explain why it seemed wrong
- Address: If actual cheating, handle seriously
Teaching Healthy Cooperation
The Four Principles of Good Cooperation
Principle 1: Everyone Contributes
- Each teammate has role
- Actively avoid social loafing
- Rotate leadership
Principle 2: Respectful Disagreement
- Express different ideas without conflict
- "I think we should try X because..."
- Listen before deciding
Principle 3: Consensus Building
- When disagreeing, find synthesis
- Vote if necessary
- Accept team decision even if you disagree
Principle 4: Shared Success and Failure
- Win together, lose together
- No blaming individuals
- Analyze team process, not individual errors
Addressing Unhealthy Cooperation
Scenario: One child dominates, others passive
Intervention: "Pause. Everyone must contribute one idea before we continue." "Jamie, you've shared three ideas. Let others speak now." "Alex, what do you think we should do?"
Scenario: Conflict escalates during cooperation
Intervention: "Stop. Take 30 seconds everyone thinking independently." "Now each person shares their idea." "What's one thing good about each idea?" "Can we combine them?"
Scenario: Team blames individual for failure
Correction: "We succeed or fail as team. What could the TEAM have done differently?" "Blaming one person prevents learning. What system would prevent this next time?"
Measuring Development

✅ Accepts losses without tantrums (after initial disappointment) ✅ Congratulates winners genuinely ✅ Analyzes own performance objectively ✅ Motivated to improve, not just win ✅ Plays by rules even when cheating would help ✅ Respects opponents regardless of outcome
Score: 1 point per behavior observed consistently 6/6: Excellent competitive skills 3-5: Developing 0-2: Needs support
Cooperative Skills Assessment
Observable behaviors indicating healthy cooperation:
✅ Listens to teammates before speaking ✅ Contributes ideas without dominating ✅ Handles disagreement respectfully ✅ Accepts team decisions even when disagreeing ✅ Celebrates team success regardless of personal contribution ✅ Takes shared responsibility for failures
Score: 1 point per behavior 6/6: Excellent cooperative skills 3-5: Developing 0-2: Needs support
Real-World Transfer
Game-developed balance transfers to:
Academic settings:
"My daughter thrives in both individual exams (competitive skills) and group projects (cooperative skills). Teachers note she's unusually balanced—contributes to teams but also works independently excellently." — Parent feedback
Sports environments:
"Football combines team cooperation and competitive drive. My son's game-based learning directly transferred—he passes when it helps team but also competes fiercely to improve individually." — Bristol parent
Future careers:
"Every job requires both. Cooperating with team while competing for promotions. My children's balanced exposure prepares them perfectly." — Manchester parent
Conclusion: The Power of Both
Competition teaches individual excellence. Cooperation teaches collective achievement. Both together teach complete humans.
Children need:
- Competition to develop resilience, accountability, and drive
- Cooperation to develop empathy, communication, and teamwork
- Mixed modes to integrate both in complex contexts
Traditional schools often:
- Overemphasize competition (grades, rankings) OR
- Overemphasize cooperation (constant group work)
- Rarely balance both effectively
Game-based learning at home lets you:
- Control the ratio
- Adjust to child's needs
- Monitor and improve balance
- Develop both skillsets systematically
