Nice explanation of a tricky idea

The Treachery of Images - Wikipedia, the free encyclopedia

The Treachery of Images (French: La trahison des images, 1928–29, sometimes translated as The Treason of Images) is a painting by the Belgian René Magritte, painted when Magritte was 30 years old. The picture shows a pipe. Below it, Magritte painted, "Ceci n'est pas une pipe.", French for "This is not a pipe."

The famous pipe. How people reproached me for it! And yet, could you stuff my pipe? No, it's just a representation, is it not? So if I had written on my picture "This is a pipe," I'd have been lying![2]

The theme of pipes with the text "Ceci n'est pas une pipe" is extended in his 1966 painting, Les Deux Mystères.[3] Currently it is shown at the Los Angeles County Museum of Art.

Sharrock's insight:

This simple work of art does so much to the critical thinking mind. Discussion beginning with it can lead to great understanding of the issues/challenges of symbols, the map-territory relation, the insights and cognitive/intellectual traps of models, etc. And, of course, it can begin a discussion about the validity and relevance of testing and assessment. The snapshot of a student is not the student.

The education question we should be asking

The education question we should be asking | School Leadership, Leadership, in General, Tools and Resources, Advice and humor |

One area of education that doesn’t get enough attention in the loud education reform debate is exactly what is worth learning. In the following post Alfie Kohn explores this problem. Kohn ( is the author of 13 books about education, parenting, and human behavior, including “The Myth of the Spoiled Child: Challenging the Conventional Wisdom about Children and Parenting,” just published this spring. He lectures widely across the United States and abroad.

What is worth learning? This has been a question asked in educational research for some time i.e. John Dewey and is still being asked i.e. Bill Pinar and David Jardine. What is worth whiling over is not a bureaucratic and technocratic question, but one which comes to life in classrooms.

Alfie Kohn. Brilliant

Andreas Schleicher: Use data to build better schools | Video on

How can we measure what makes a school system work? Andreas Schleicher walks us through the PISA test, a global measurement that ranks countries against one another -- then uses that same data to help schools improve.
