A chicken pecking problem

The following problem was posed in the 2017 Raytheon MathsCounts national competition: In a barn, 100 chicks sit peacefully in a circle. Suddenly, each chick randomly pecks the chick immediately to its left or right. What is the expected number of unpecked chicks? The competition is aimed at 13 to 15 year olds, and they have just 45 seconds to answer - the first with the correct solution wins. In this case, a 13 year old Texan boy came up with the answer in ...

Pre-IB (4): TOK Assessment

The previous three blogs have focused on a general introduction to TOK, an overview of the content of the course (Areas of Knowledge) and a look at the methods for producing knowledge (Ways of Knowing) found in the course. This final Pre-IB blog looks at the way in which TOK is assessed. This consists of an externally assessed piece, the TOK Essay, and an internally assessed piece, the TOK Presentation. Both are necessary in order to pass the TOK component ...

Pre-IB (3): The ‘how’ of TOK

The ‘how’ of TOK focuses on the methods by which knowledge is produced in the different Areas of Knowledge (AoKs). In TOK these methods have been identified as the eight Ways of Knowing (WoKs). They are Reason, Sense Perception, Emotion, Language, Memory, Imagination, Intuition and Faith. Each WoK provides a particular way of producing or accessing knowledge. Whilst an individual understanding and analysis of each of them is expected, the IB emphasizes that it is also important to see how they ...

Pre-IB (2): The ‘what’ of TOK

The ‘what’ of TOK refers to the knowledge produced by human thought. Human knowledge is divided  into Areas of Knowledge (AoKs). Those units generally combine subjects which have similar methods, scope and goals. There are eight of them. Natural Sciences, Human Sciences, History, Mathematics, the Arts, Indigenous Knowledge, Ethics, and Religious Knowledge. TOK will not only make you look at these areas of human thought from a new perspective but it will also highlight the connections and differences between them ...

Pre-IB (1): What on Earth is TOK?

When asked about what makes IB students better ready for university than others, admissions officers tend to highlight two things, the Extended Essay and TOK. TOK, which is short for Theory of Knowledge could be regarded as the heart and the crown of the IB. It forms the foundation of the whole programme and it elevates the DP curriculum to a level of sophistication not achieved by other qualifications. Sure, it is possible to pursue courses in Critical Thinking outside ...

Russell on the elusive knowledge of the Self

In ‘The Problems of Philosophy’ (1912), Bertrand Russell pays tribute to the French philosopher, René Descartes, for performing ‘ great service to philosophy’ by introducing a rational method of doubt in the search for truthful knowledge. He doesn’t identify any apparent difficulty in the Cartesian assumption that everything outside my own thoughts, feelings snd sensations, could be a mere fantasy. However, he brings his own realist interpretation to bear on the argument, when he comments that, despite the logical possibility ...

Portugal in World War I

In June, 1917 Portuguese troops saw their first action as battle-ready troops in France.  Why is this significant?  There is a tendency to highlight the entrance of the US in the First World War in 1917 but all of this shows the global nature of the war.  It is true that Portugal had a long-standing agreement with the UK (and Great Britain, and England) and its entrance was part of this relationship but it was also about colonial possessions in ...

Scientific Morality?

Can Science provide a better basis for morality than other forms of human knowledge such as religion, psychology or philosophy? A look at the history of moral philosophy shows that by and large every significant contribution to ethics has come primarily from philosophers or theologians. It is not until the late twentieth/early twenty first century that some scientists have proposed that science can be a better basis for ethics, in other words that the answer to the question “how can ...

Moving your literature teachers to be more daring

It is pretty well known that when it comes to choosing the works you will study in your syllabus, teachers are in control, in most cases, of the process. Many considerations play into this: the school situation in terms of boards which have oversight of schools, budgets, personal preferences, and school aims and philosophy. Nevertheless, sometimes teachers can be invited and nudged to go in new directions and sometimes, just sometimes, you can have a role in that. So let’s say there ...
