Wonderful Series Of Illusions


I’ve described in one of my New York Times posts how I use illusions with English Language Learners, and I obviously use them in IB Theory of Knowledge classes when studying Perception.

I just learned from Michelle Henry about a series of illusions created by Mexican painter Octavio Ocampo who, I’m embarrassed to say, was not familiar with prior to seeing this work.

Go take a visit — they’re amazing!

Very Impressive NY Times Interactive: “Police Body Cameras: What Do You See?”


Police Body Cameras: What Do You See? is a new very impressive interactive at The New York Times.

After first soliciting the reader’s general feelings about the police, the interactive shows several staged police encounters from different cameras and angles – asking you to judge what you think you saw. Then, those judgments are compared to other what others said and their feelings about the police.

It’s extraordinarily useful to just about any class, and will be a superior addition to my Theory of Knowledge lesson on perception, Videos: Here’s The Simple Theory of Knowledge Lesson On Perception I Did Today. That post shares several other videos showing the same event from different angles.

Video: “Richard Feynman on What It Means”

I’ve written and shared a lot about the late Nobel Prize winning physicist, Richard Feynman (you can see all my previous posts about him here).

I’ve also shared many videos from PBS in the “Blank on Blank” series, where they take excerpts of older interviews with key players in history and turn them into animated shorts.

Well, today, Blank on Blank unveiled one they did with Feynman, and it’s definitely worth watching:

Over 2,500 Categorized Resources For IB Theory Of Knowledge Classes

As regular readers know, in addition to teaching various classes to English Language Learners and to mainstream ninth-graders, I teach the International Baccalaureate Theory of Knowledge course. I also regularly share TOK resources here on the blog, and I think it’s pretty popular among TOK teachers around the world.

This post is my regular “quarterly reminder” that, in addition, I accumulate links to articles and resources on the Delicious bookmarking site, and now have over 2,500 categorized into the all the TOK “Ways of Knowing” and “Areas of Knowledge.” I typically add about twenty or so new ones each month.

However, they don’t necessarily include all the resources I share in my regular Best Theory Of Knowledge Resources posts.

You can find most of them here.

However, for some weird reason, not quite all of the “tags” are visible at that link. Here are direct links to the WOK and AOK resources not listed in the above link:


Logic and Reason (They’re separate, but all related. I think I first started using the logic tag and later switched to reason)

Indigenous Knowledge Systems


Intuition (though most are still in the Emotion category)

Human Sciences

The BBC’s “A History Of Ideas” Video Series Is Great For TOK Classes

history of ideas

You may, or may not, be familiar with the BBC’s “A History of Ideas.” It’s a show with 72 one-hour podcasts and 48 accompanying short video animations about philosophy.

You can access all the podcasts and videos on the BBC site, which is particularly nice since a lot of the other material on the BBC won’t play in the United States.

All the video animations are also on YouTube.

I’ve previously shared some of the videos. Here’s one:

NPR Videos On Serendipity In Science


When we study science in IB Theory of Knowledge, one of the ideas we consider is that not all scientific breakthroughs come through rigidly following the scientific method.

NPR recently did a short series of videos examining just this: “modern examples of serendipity in science – happy accidents/mistakes/coincidences from the last few years that have led to discoveries and insights.”

They’ll be useful in TOK class, and here they are:
