“The principle idea behind PBL is that the starting point for learning should be a problem, a query, or a puzzle that the learner wishes to solve.”
Boud, D. (1985) PBL in perspective. In “PBL in Education for the Professions”
Just What IS PBL?
Just What IS PBL?• Learning is initiated by a
problem or open-ended question.
• Problems are based on complex, real-world situations.
• All information needed to solve problem is not initially given.

Specifically FIZZIX PBL Problems…Typical Text vs PBL Problem #1:
Basic Vector Problem from text…Basic Vector PBL!!! (Thanks to CIESE) You are a Stowaway on a ship somewhere at sea. You want to figure
out where you are headed and when you will arrive. Being a good TechnoTwit, you remembered to bring your laptop, satellite-phone, and modem and you remember a shipmate mention the Ship’s ID code.
What’s involved with the Stowaway PBL?
1.Use the internet to locate your position (Backup)
2.Find where the ship CAME FROM. (Backup)
3.Double check with Online Data center. (Backup)
4.Include wind & gulf stream & speed info for vector analysis. (Backup)
5. Learn Latitude/Longitude.
• Gather OWN data!–Not someone else’s
• Analyze their OWN data!–Solution not predetermined, so
cheating by working backwards ain’t happnin’!

How true that is.”

Basic Vector PBL!!!… Use real-time data to determine the vectors affecting a commercial plane’s flight pattern.
• Flight Tracker - Real time flight tracking information (BU)
• Airport Information - Find an airport's exact location (BU)
• How Far is it? - Find latitude and longitude of a specific location by typing location in "From" section. (BU)

You must land the plane as QUICKLY as possible or you will lose a passenger. You must choose an airport where you will land the plane.

Specifically FIZZIX PBL Problems…Typical Text/Class Problem #3:
A 1500-kg car traveling east with a speed of 25 m/s collides at an intersection with a 2500-kg van traveling north at a speed of 20 m/s. Find the direction and magnitude of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (ie, they stick together).

• Invite local Police in!!!– Based on police sketch– Students need to make assumptions and
approximate– Information given gradually throughout
problem– Students draw conclusions based on real
data!
