Statistics – On Average They Work

Filed under: TOK — Tags: , , , , — triplea_cw @ 10:12 am

When should we trust statistics?

It is easy to spend an entire lesson looking at statistics whose intent seems to distort a reader’s understanding of an event. A classic work on my early years of teaching TOK was How to Lie with Statistics by Darrell Huff and then Damned Lies and Statistics: Untangling Numbers from the Media, Politicians, and Activists by Joel Best. The latter book discusses the travels of both good and bad statistics. Notably, Best talks about the source of bad statistics – bad guesses, descriptive definitions, confusing questions and biased samples; mutant statistics. And the ways in which good statistics can be mangled, misused and misunderstood; as well as the problems of statistical comparison.

Looking for a common thread that covers topics and structures taught both in the MYP and the Diploma Programme, I came up with one idea.

Maths, laments and games

Maths teacher and student in the 16th century

What does this picture tell us about the role of a Maths student in the XVI century ? Look at his eyes, his hands. Does he seem to have an active, engaging participation in the learning process? Is this quite different from our own experience as students some years ago?

Age and Knowledge: The Myth of Age and Wisdom?

Filed under: TOK — Tags: , , , — triplea_cw @ 1:31 am

In trying to counter one of many classic misunderstandings of knowledge, that knowledge is always progressive, I delve into the issue of when an individual does their best work in various Areas of Knowledge.

I give them three individuals (images from the net help their thinking):

Probably if Gollum (from the Lord of the rings) would have known the new software we can find in http://prezi.com

he would have desired to use them as well.

One of the things that I really like about the MYP philosophy is the importance that it gives to Interdisciplinary activities.

A Comic Approach: TOK and Maths

Filed under: TOK — Tags: , , — triplea_cw @ 10:59 am

Have a look at this new approach to a topic that can struggle to engage students. See an assessment and sample of a page from the comic book in Jim Holt’s “Algorithm and Blues“, published in The New York Times.

“Well, this is unexpected — a comic book about the quest for logical certainty in mathematics. The story spans the decades from the late 19th century to World War II, a period when the nature of mathematical truth was being furiously debated. The stellar cast, headed up by Bertrand Russell, includes the greatest philosophers, logicians and mathematicians of the era, along with sundry wives and mistresses, plus a couple of homicidal maniacs, an apocryphal barber and Adolf Hitler.”

I am sure this will get a few students interested in this fascinating and essentially TOK topic. I would like to use the section devoted to Bertrand Russell’s visit to Paris during the 1900 International Congress of Mathematicians. At this conference, Henri Poincaré and David Hilbert – the two greatest mathematicians of the day – argued over the importance of intuition versus proof. An essential TOK discussion!

A Quick Lesson ‘Pick-me-up: Abbott and Costello explain Maths

Filed under: TOK — Tags: , — triplea_cw @ 10:45 am

I was looking for a humourous introduction to a lesson that involved Maths as an Area of Knowledge. I stumbled across this goldern oldie that I haven’t used for some years now – it is still very fresh.
