How he wishes he'd taught maths: Craig Barton on improving your teaching, lethal mutations and problem solving

Over the last few years, Craig Barton has made quite a name for himself in the field of mathematics education. In his first book, "How I Wish I'd Taught Maths: Lessons learned from research, conversations with experts, and 12 years of mistakes" (2017), he describes in much detail exactly what its title suggests. Three years ago, the book was translated into Dutch by René Kneyber and given the appropriate name "Volgens Barton". It's a play of words on the Dutch saying "volgens Bartjens", which means "from basic reasoning it follows that" - that saying in turn refers to the seventeenth century schoolmaster Willem Bartjens and is also the title of a Dutch magazine on mathematics education. A workshop based on the book, which was supposed to take place in March 2020, was postponed several times due to the Covid pandemic and finally took place in June 2022. In the meantime a second book was published: "Reflect, Expect, Check, Explain: Sequences and behaviour to enable mathematical thinking in the classroom" (2020). Mark Timmer and Wim Caspers were present to attend the workshop and interview Craig afterwards, and learnt that a third book may be on its way.
