  • It's not that people cannot think mathematically. It's that they have enormous trouble doing it in a de-contextualized, abstract setting.
  • absent any clear evidence as to how best to proceed, the majority of teachers quite understandably default to more or less the same teaching methods that they themselves experienced. Overwhelmingly that is the traditional method, though the fact that no one has been able to make this approach work (for the majority of students) in three-thousand years does make some wonder if there is a better way.
  • the majority of claims made about the efficacy of various pedagogies are based on nothing more than an extrapolation from personal experience (of the teacher, not the student)

  • In the nineteenth century and for much of the twentieth, most industrial workers did work silently on their own, in large open offices or on production lines, under the supervision of a manager. Schools, which have always been designed to prepare children for life as adults, were structured similarly. An important life lesson was to be able to follow rules and think inside the box. But today's world is very different - at least for those of us living in highly developed societies. Companies long ago adopted new, more collaborative ways of working, where creative problem solving is the key to success - the ones that did not went out of business - but by and large the schools have not yet realized they need to change and start to operate in a similar fashion.
  • I ask you, which is the more important information: the score on a standardized, written test taken at the end of an educational episode, or the effect that educational episode had on the individual concerned?
  • teaching math in the progressive way requires teachers with more mathematical knowledge than does the traditional approach (where a teacher with a weaker background can simply follow the textbook - which incidentally is why American math textbooks are so thick)
  • First, the students were completely untracked, with everyone taking algebra as their first course, not just the higher attaining students. Second, instead of teaching a series of methods, such as factoring polynomials or solving inequalities, the school organized the curriculum around larger themes, such as "What is a linear function?" The students learned to make use of different kinds of representation, words, diagrams, tables symbols, objects, and graphs. They worked together in mixed ability groups, with higher attainers collaborating with lower performers, and they were expected and encouraged to explain their work to one another.

    The US ranks much worse than most of our economic competitors in the mathematics performance of high school students. Many attempts have been made to improve this dismal performance, but none have worked. To my mind (and I am by no means alone in thinking this), the reason is clear. Those attempts have all focused on improving basic math skills. In contrast, the emphasis should be elsewhere.

    Jeg skulle gjerne ha gjort mye flere prosjekter/utforsking/åpne oppgaver osv. Men jeg er redd for eksamen. Dessuten - mange lærere tør ikke å innrømme at de knytter seg opp til boka- jeg må ha mye mer støtte fra en bok før jeg har TID (og peil) til å sette i gang)
