Critical thinking...

One of the biggest challenges that I face as a lecturer is helping the students to develop their critical thinking skills, especially with regards problem solving as this is one of the key skills an engineer should possess.

It's a fundamental skill for a practicing engineer to not only problem solve, but to critically review the problem and reconstruct it so that only the important parts are focused upon.  Essentially honing in on the nub of the problem.

I'm a fan of using stories in lectures and I used to work with an Italian engineer who unfortunately died last year and he had a plethora of stories and anecdotes that he paraded out whenever the occasion arose.  One of his numerous stories that sticks in my mind and that I think I'll start using in my lectures about critical thinking involves three construction professionals on a train ride to Scotland for the first time.

There is an Architect, a Project Manager, and an Engineer on a train together and as they cross the border into Scotland for the first time on a train racing through the countryside they spot a brown cow in a field.

The Architect, being the first to spot the cow, declares that clearly all Scottish cows are brown, the Project Manager who feels that he clearly has the organisational skills to rationalise this observation and thinks that the architect hasn't been critical enough, decides to correct the Architect and notes that in reality what the Architect has actually observed is that in Scotland there is a field which has brown cows.

The Engineer meanwhile has been listening intently to this discussion and decides to correct them both by sharing his observation, that in fact there is in Scotland, a field, that contains a cow, one side of which is brown.
