In praise of math, logic, and Latin … say, what?

May 31, 2018

Classical educators argued that these disciplines are the building blocks of reasoning, problem-solving and critical thinking.

=======

The courses that I teach contain a heavy dose of problem-solving skills.

Early on, I assert my belief that that problem-solving skills can be taught – and, more importantly, learned – and set about to prove the point.

I’ve been doing some summer reading on the topic of reasoning & problem-solving and learned:

“For twenty-six hundred years many philosophers and educators have been confident that reasoning could be taught.”

In praise of hard copies and writing things down …

May 25, 2018

Ran across an article by Eric McNulty —  the CEO of LinkedIn:  Journaling Can Boost Your Leadership Skills .

As the title suggests, he was advising busy managers to to take some time each day  to record their deep thoughts in a journal.

Seems like a reasonable idea … but that’s not what caught my attention.

As a teacher, I’ve had to adapt approaches to leverage the ways that students process information … especially as the world goes all-digital.

One of my conclusions: digital provides many benefits, but also seems to restrict our capability “go deep”, to “connect the dots” and to draw insights.

Why might that be true?

I do my best thinking when I’m sleeping … say, what?

April 23, 2018

Discussing creativity in class, I casually mentioned that I seem to do my best thinking when I’m asleep.

Specifically, I reported that I like to get to work as soon as I jump out of bed (literally) … and that I often find myself doing a brain dump of thoughts that weren’t top of mind before I’d gone nite-nite.

The revelation initially got some chuckles … then some folks started nodding and chiming in with “me, too” variants on the story.

Of course, some remained unconvinced.

Dilemma: The case of the lost concert tickets …

April 10, 2018

Here’s a classic “framing” question from Kahneman’s Thinking Fast, Thinking Slow

Here’s the situation:

A woman has bought two $80 tickets to the theater.

When she arrives at the theater, she opens her wallet and discovers that the tickets are missing.

$80 tickets are still available at the box office.

Will she buy two more tickets to see the play?

Most (but, not all) survey respondents answer that the woman will go home without seeing the show.

Let’s try another situation …

So, are you left-brained or right-brained?

Yesterday’s post prompted some questions re: what exactly is left-brained and right-brained thinking, so … 

For decades cognitive psychologists has characterized folks as being either left brain dominant  – logical – or right brain dominant – creative.

When can you “trust your gut”?

May 3, 2016

I teach problem-solving in my courses and preach that intuition is a good thing – not flying by the seat of your pants — but rather, sub-consciously tapping into your cognitive storehouse of education, experiences and emotions.

The more you learn, the more you practice and the more you discipline yourself mentally … the better you get as a problem-solver.

Digging deeper, I came across an interesting article in Inc., positing that intuition is evident in 4 distinct types of “thinking preferences” which are naturally intuitive in different ways…

Problem Solving Tips: Patterning, framing and the astronaut’s pen …

February 18, 2015

Excerpted from Think Better

Among the many discoveries NASA made when it began sending people into space was that the astronauts’ pens did not work well in zero gravity.

The ink wouldn’t flow properly. You can simulate the effect at home by trying to write with the business end of your pen pointing up.

Pretty soon, the ink stops flowing and the pen won’t write.

The solution – giving astronaut’s a way to write upside down —  depends on how you frame the problem …

As you consider this question, please assume that Steve – the subject — was selected at random from a representative sample.

Steve has been described by a neighbor as follows: “Steve is very shy and withdrawn, invariably helpful but with little interest in people or in the world of reality. A meek and tidy soul, he has a need for order and structure, and a passion for detail .”
