Sense perception: Yanny or Laurel?

(Eileen Dombrowski, from OUP blog) Create a 5-minute buzz in TOK class over sense perception.  Which version of the words do your students hear? It seems that groups of people are truly split over how they interpret the sound file! The first video here (from The Guardian) simply gives the options – as you’ll want just to get your class going – while the second (from CNN) gives some variations and a bit of explanation.

A TOK class for exam month: mathematics, nature, art, technology…and peaceful contemplation of beauty

(by Eileen Dombrowski, from OUP blog) May in the northern hemisphere.  The return of long daylight.  But also IB exams. Tired students. Tired teachers. Time to take a class into the calm and beauty of pattern, with gentle TOK reflection on the deep intersections of mathematics, nature, art and technology. This year, my favourite vehicle is the animated sculpture of John Edmark, especially with the video “Creating the Never-Ending Bloom” in which the designer is commenting on his work.

Signed language, symbolism, and reflections on inclusion

(by Eileen Dombrowski, from OUP blog) I learned something important from my friend Lynx – something important for how I think about TOK and knowledge. It was almost seven years ago. I was interviewing her, as an experienced New Zealand Sign Language interpreter, on how signed languages worked and what they tell us about the nature of language. I was keenly interested in the ideas – and on using my laptop to make a video for the very first time. Then, when I had finally edited the interview, I passed it to Lynx for her response. It was immediate. “Can we add closed captions?” she asked. I was mystified. Why would we do that? “I wouldn’t like to talk about the Deaf community and their knowledge,” she explained, “without their having access to what I’m saying.” In an abrupt shift of perspective, I suddenly thought about the function of the closed captions I had always ignored – and realized that she was right. I had anchored my thinking entirely in my own TOK community and relationships of ideas. As an interpreter between hearing and Deaf groups, Lynx was much more fully attuned to the people. She was talking about inclusion and respect. Continue reading

SPOT and the cloak of invisibility: cognitive biases

170925 cloak

For the observer: a cloak of invisibility?

(Eileen Dombrowski, from OUP blog) With a laugh, I pass on to you today a couple more cognitive biases, ones that students are likely to enjoy. We could, of course, despair over how deep our biases seem to go and what a challenge it is to achieve an open mind, but I find it curiously entertaining to learn about the quirky biases of our human minds. Maybe it even creates some patience with other people – those others who are so stubbornly wrong! – if we recognize that we are also naively wrong ourselves.

When considering reason as a way of knowing, we Theory of Knowledge teachers have long treated fallacies that derail clear thinking. When considering intuition as a way of knowing, we have a wealth of material in all the biases that kick in before we’re even consciously thinking. At moments, I’ve idly wondered whether we could teach the entire TOK course centred on confirmation bias, our tendency to notice and accept only information that reinforces what we believe already.   Continue reading

Film sound and the beautiful lie

(by Eileen Dombrowski) “Our brains are conditioned to embrace the lies,” Tasos Franzolas declares of the sound engineering in films. This TED video (16:33 minutes) is a winner for any TOK treatment of sense perception and interpretation, and of the fusion of technology and creativity in the arts. Continue reading

Is mathematics a gateway to empathy?

(by Eileen Dombrowski, from OUP blog) Is the study of mathematics really a gateway toward empathy? I’m not fully convinced by the argument presented by mathematician Roger Antonsen, but I like him for making it. We need all the empathy we can get in our world. Certainly, his mathematical visualizations  do demonstrate the importance of mental flexibility and imagination in mathematics, and do stand metaphorically for being able to see from different points of view. And his argument leads to some interesting knowledge questions about perspectives and empathy. Continue reading

The Beach Beast: perceiving pattern, playfully

(by Eileen Dombrowski, from OUP blog) Cute, isn’t he? May I introduce to you the Beach Beast, and a playful class example for sense perception and intuition as ways of knowing? Oh yes, we TOK teachers all have our collections of optical illusions and suggestive images to create a gestalt moment. (Aha!)  We might even use the word “pareidolia” in class for the brain’s inclination to find pattern in random sense perceptions – with human faces, for example, startlingly apparent on the surface of the moon or the melted cheese sandwich on our plate. But, really, I think you’d have to go far to find an example with the appeal of my local Beach Beast!

Beasts, whirligigs, and raindrops: engineering, art, and the play of the imagination

(by Eileen Dombrowski, from OUP blog) On this fine day in May, most Theory of Knowledge students in the northern hemisphere are surely preoccupied with only a certain aspect of knowledge: how well they have demonstrated it, in relevant forms, on examinations. So today let me suggest that tired students deserve to be invited away from exam stress through their senses and imaginations, and through a gentle form of TOK reflection.

I’d give them no taxing questions, but instead the chance simply to watch and respond to Theo Jansen’s Sandbeasts:

“Who’s an Indian now?”: concept, definition, and significant ruling

(by Eileen Dombrowski, from OUP blog) A unanimous ruling by the Supreme Court of Canada on April 14 gives us a dramatic example to take to a Theory of Knowledge class: Métis and non-status aboriginal people in Canada are now defined as “Indians” by the federal government. The people who now fit into this category are celebrating. The implications are significant for the rights they can now claim, the programs and services to which they now have access, and the increased clarity of their place in federal and provincial jurisdictions. Moreover, some consider it to be an acknowledgement of their history and a validation of their identity. But why do I suggest a judicial ruling with political ramifications as an example for a class on knowledge? What does it illustrate that is relevant to our course? Continue reading

Perspectives and manipulation: 6 photographers and a single subject

(by Eileen Dombrowski, from OUP blog) At first glance, this three-minute video (6 Photographers Capture Same Person But Results Vary Widely Because of a Twist) provides a visually engaging, if rather obvious, illustration of differing perspectives at work as 6 photographers take distinctly unlike pictures of the same subject. Taken at face value, it’s an appealing resource for a TOK class on the effect of what we think (perspectives, WOK intuition/reason) on what we see (WOK sense perception) and how we represent the world (WOK language). It’s when we question the methods of the film makers, though, and the reach of their conclusions, that the video becomes richer in questions that we want to raise in Theory of Knowledge.
