Problem-Based Learning

PBL (problem-based learning) is a student-centred method of teaching in which students learn by investigating real-world problems and, working in groups, seek out the tools necessary to solve them.

Investigation Phase• Enquiry and experiment

Analysis Phase• Share and discuss information• Apply new information to the problem• Evaluate progress• Submit work or revisit plan • Reflect

Solution to spiders web:

A colony for high food density. http://www.dailygalaxy.com/my_weblog/2007/09/giant-spider-we.html 

But – is this unique?  Solution to whales:  

Endangered species in Galapagos: see for example http://www.youtube.com/watch?v=UbUOK3k21os 

How endangered? Is it just hunting (what about local economy or tourism?) Solution to Spiders’ web: 

Trapping the bat requires strong fibres: investigate polymer cross-bridges and/or web structure  Solution to tower:  

Hot air rises and drives turbines.  

Why in the desert? Is this efficient compared to solar electricity?  Solution to Fairchild  Chimera – non-uniform tissue types 

How can this be? What determines tissue type?

16

How did we do? Planning Phase – What is the problem? What do we know?

Investigation Phase - What do we need to find out Who and what?

Analysis Phase – Have we solved the problem fully? (Repeat as necessary)

Assessment – Report

Evaluation – Group roles
