Broad-spectrum tactics More-targeted methods
Entrepreneurially Minded Learning is…
A pedagogical method Part mindset part skillset Student centered - for everyone
NOT the entire solution for good teaching NOT a prescriptive sequence of steps or checklist
Entrepreneurially Minded Learning is…
NOT new, especially in other disciplines NOT easy for learners or instructors
Entrepreneurially Minded Learning is…
EML emphasizes… entrepreneurial thinking; 3C’s
-curiosity engaged discovery divergent epistemic trends
-connections contextual extra-contextual insight
-creating value
Others-oriented
opportunity recognition Action and Adaptation
- look toward the future - ownership
- assumed risk and reward - success despite variability and uncertainty
EML does not have exclusive rights to 3C’s!

I’ll find the opportunity.”
Is a simple topic, like flashlights, college worthy? Yes, actually.

Active and Collaborative Learning Measure voltage, current
Measuring the resistance of the bulb
Try some experiments with batteries - “dead” batteries - end-to-end
“Stack” batteries with other groups to sup-up flashlight
Problem-based Learning #1 We need twice as much light for a maximum 10% design cost and manufacture increase. Need similar size and weight design.
Problem-based Learning #2Current battery-powered flashlights are insufficient or cumbersome for search and rescue operations.
(closer to EML)
Focus on Information Gaps
- Identify deficiencies of your model - Is the case is a “wire” in the model? - Are there unaccounted losses?
- Contacts? - How significant?
- What is dynamic filament resistance? - What are the source limitations?
- output resistance - electrochemical
EML emphasizes CURIOSITY
Focus on Curiosity Types
- Epistemic curiosity — Why, why, why? - Why is the cell voltage typically 1.5V? - Why are the batteries this size and weight? - What underlies the limits of the electrochemistry and battery design? - What is the efficiency (power into light vs. heat)?
- Diversive curiosity — What if ? Could we ? - What actually happens if the batteries are reversed or back to back?
- Extra contextual: What if I plugged to 9V batteries together? - What are alternate sources? - What are alternative light sources? - Is there an electrochemical reaction that produces light directly?
EML emphasizes CURIOSITY
Focus on Trends
Trends reflect the “changing world around us.”
Does anyone really buy a flashlight (or just use a phone)?
EML emphasizes CURIOSITY
Problem-based Learning -> EML #3
Who purchases flashlights, anyway?
Everyone has a cell phone with an LED feature. What more does the average user need?

EML emphasizes CONNECTIONS:
Build a map… Exercise your curiosity… Be both random and methodical… Lab notebook… Own it… (not just another assignment, part of your “profile”)
