“Evidence-based medicine”: a class discussion, with a caffeine lift!

1507coffeeDid you know that green coffee bean extract can help you lose weight? No? Me neither! Today, I’d like to propose a class discussion on thinking critically about media knowledge claims for products that yield fabulous (literally) medical benefits. The discussion is given a caffeine lift by a bite-sized example from a year ago – a story of fabulous claims and the corrective process of science. Continue reading

Backward Brain Bicycle: memory and knowing how

(by Eileen Dombrowski) “Knowledge”. “Understanding”. “Truth”.  Your students might want to argue with the way Destin Sandlin uses the terms — and so will you — as he struggles to learn how to ride what he calls the Backwards Brain Bicycle. This video is likely to provoke ripples of laughter and to animate discussion on “knowing how” and memory as a way of knowing.  Not a bad lead-up to knowledge questions! Continue reading

Mathematics and Scientific Methodology: example Malaria

insect-158565_640(by Theo Dombrowski) The statistics are horrifying.

 Every minute, a child dies from malaria.

In 2013, 90% of the world’s malaria deaths occurred in Africa and over 430,000 African children died before their fifth birthdays.

And there are plenty more statistics where these came from:

In 2013, there were about 198 million malaria cases (with an uncertainty range of 124 million to 283 million) and an estimated 584 000 malaria deaths (with an uncertainty range of 367 000 to 755 000).

According to yet further statistics, this horrifying number is not as bad as it was just a few years earlier. Why the improvement? Mostly, it seems, from two causes: increased availability and use of both insecticides and mosquito nets over sleeping areas.   Medical research still has not led to a vaccination.

Malaria research as an example for TOK class

The research and experiences of IB graduate Dr. Miles Davenport provide excellent insight into the methods currently being employed in the biological sciences to combat this huge health issue faced principally by the world’s poor.

Two aspects of current malaria research are most helpful to bring to a TOK class. The first concerns those elements absolutely basic to gaining scientific knowledge–making observations, collecting data, making assumptions, and formulating hypotheses. The second, Dr. Davenport’s specialty, is less obviously fundamental–applying mathematics.

World Refugee Day: What do our categories leave out?

refugeeUN300Today, a PS to this past week’s posts on classifying human beings. What do our categories highlight, and what do they exclude? My past two posts have used current examples from the media to raise knowledge questions about “race” and the contentious balance between biological heritage and culture or ethnicity (a balance that carries varies labeling in various contexts). Today I’d like to comment, just briefly, on another classification of human beings, one that carries enormous significance for how we live in the world Continue reading

Classification and implications: Who is black, or indigenous, or Jewish?

(by Eileen Dombrowski) I ended my last post with questions about Rachel Dolezal’s claims to be black: “Are her personal knowledge claims the deciding factor, in your mind, for determining her racial identity? Why or why not?” What has captured media attention, it seems, is the way in which her story pits her own personal knowledge claims about her own racial identity against social knowledge claims of racial classification – and this in a society where racial categorization is charged with assumptions, associations from history and politics, values, and implications for treatment.

What captures my own TOK attention, however, is more generalized. It’s the differing bases and justifications for general classifications, of course. But even more intriguing is the way particular examples fit – or, being human, sometimes dramatically refuse to fit – into the categories assigned to them. As soon as we take two steps back from Rachel Dolezal’s story, others flood into the space. Who is black? Who’s an Indian? Who’s Jewish? Continue reading

“Passing” as black: classification and social implications

A story currently running in the media jolts me out of summertime diversions, straight back to TOK. I find knowledge questions about classification magnetic, especially when the categories constructed have social and emotional resonance as they are applied to human beings – as has the categorization of “race”.

This week’s incident gives an interesting twist to American stories of people of one race “passing” as another. Rachel Dolezal, president of a Washington state chapter of the National Association for the Advancement of Colored People (NAACP), has been exposed by her birth parents as lying about being black. She is white – and they have the birth certificate to prove it. Many people have condemned her deception, including her black adopted brother who describes her “blackface” as “a slap in the face to African-Americans”.

Yet she is clearly a leader in Washington state’s black community, an expert on Black American culture, and an advocate for the community on issues of civil rights. Asked by a reporter whether she was black or white, Dolezal responded only, “That question is not as easy as it seems. There’s a lot of complexities … and I don’t know that everyone would understand that.” Continue reading

Eileen’s advice for new TOK teachers

fish-158662_1280

— “I’ve never even taken a course like IB Theory of Knowledge, and I’m not sure at all how to teach it.”

— “I’m just planning the course for the first time, and I have some ideas…”

Voices and faces linger with me as I return from a gathering of teachers (a flocking of my own kind!). Among them were many teachers new to TOK — still taking it in, connecting it with their own backgrounds, and beginning to plan. It’s to these new teachers – with their ideas, energy, and uncertainties — that I’d like to speak in today’s blog post. May I offer you some suggestions for enjoying to the full your teaching of IB Theory of Knowledge?

My last question, note, was purely rhetorical — and disingenuous. I really want to offer some suggestions and simply hope that what I prize from my own experience will find some place in your own shaping of a course that I consider central to education. I’m not at all detached, and not at all neutral: in my opinion, the whole way of thinking of TOK is crucial to the knowledge that our students should take with them as they graduate.

“Knowledge-Based Trust” (KBT): Google aims to give us the facts.

google-76517_640(by Eileen Dombrowski) Who needs critical thinking when we have Google? A team of computer scientists working for Google has proposed an improvement on what comes up when we enter our terms in its search window. They suggest a method of calculating a “trustworthiness score” for webpages based on their factual content: “We call the trustworthiness score we computed Knowledge-Based Trust (KBT).” An avid Googler myself, I am awash with both admiration and amusement. What would our students, many of them also consummate Googlers in face of essay assignments, make of the knowledge questions that instantly arise about the nature of facts, truth, and reliable sources?

Who’s an “Indian”?: classification and implications

classifying

Classification carries implications.

(by Eileen Dombrowski, from OSC TOK blog) Who’s indigenous? And does it matter? These are significant questions, with significant answers. They are relevant to TOK both through the new area of knowledge, indigenous knowledge, and an old area of knowledge, ethics – as well as to all the ways of knowing involved in classifying our concepts, and, in the knowledge framework, to the topic of concepts/language. Two stories in this past month’s news bring these questions to life: a court contest in Canada about who is classified as “aboriginal” and a conflict in Tanzania over whether indigenous people have any claim to their traditional land.

Earthquake trial acquittal: scientific prediction and responsibility

earthquake01(by Eileen Dombrowski) “Today we have an earthquake after the earthquake,” declared a grieving relative of a victim of the 2009 earthquake in Aquila, Italy,  as charges against six earthquake scientists for failing to warn people of the quake were dismissed by an Italian appeals courts this week.  The case, distressing though it is, provides a gripping example for TOK knowledge questions that surround scientific prediction and its relative uncertainty in different sciences, and, more urgently, the relationship between expert knowledge and social responsibility.
