(by Eileen Dombrowski from OUP blog) Shock waves in the human sciences! Six more of Brian Wansink’s published papers are being retracted, Cornell University announced September 20, bringing the total to 13, and the professor has resigned in disgrace. It is not just scientific peers who are affected as Brian Wansink’s flawed methodology is exposed and his papers are withdrawn from journals. Millions of ordinary people have also been influenced by his research on “mindless eating.” Nutritionists and marketers alike have also based decisions on his findings. But – what do these retractions mean for the methodology of the sciences? And – why should we seize on this example in Theory of Knowledge?

(by Eileen Dombrowski, from OUP blog) Which of her eager suitors will make the right guess in the gamble – and win the beautiful Portia and her fortune? Mathematician Alex Bellos gives us a new twist to a story familiar from Shakespeare’s The Merchant of Venice: a lovely and virtuous heiress is compelled by her late father’s will to marry the man who chooses, out of three caskets, the one which contains her portrait. In a Theory of Knowledge class, love, luck, literature, and logic combine in a quick class activity solving a problem – and thereby clarifying for students the process of deduction and justification through reason and language as ways of knowing. And it’s fun. Continue reading
(by Eileen Dombrowski, from OUP blog) Until this very moment I hadn’t realized exactly what’s been missing in my TOK classes. Zombies! I’ve been missing zombies. For years I’ve introduced terms such as “justification”, “counter-argument” and “refutation” or “falsification”. For years I’ve compared areas of knowledge on the basis of whether their knowledge claims could be tested, and whether and why people in those fields would consider rejecting them. “And so you should,” you might say. After all, that’s core TOK. But don’t you think it lacks a bit of….je ne sais quoi… a bit of colour, perhaps…a bit of personality? Wouldn’t students find refuted ideas much more attractive if presented in terms of zombies? Continue reading
(originally posted on my OUP TOK blog) Ideas can be treated at different scales. Anyone writing a paper or preparing to teach a course knows that – and Theory of Knowledge teachers most certainly do! Knowledge questions zoom skyward to such broad levels of overview that they can temporarily scale everything but the strongest contours of knowledge right out of sight. Today, I’m going to risk extreme vertigo to share with you one overview of the Theory of Knowledge course itself, scaled to a single page.
