Comment on A flawed formula by Ana

Math formulas should be used with caution. If the results affect humans and their work then formulas should be discarded completely, let’s us concentrate on the person. One example of how we abuse results is with statistics. We can pretty much develop studies to get the result we want and then draw devastating conclusions or ones that do not make any sense as the study that polled over 2000 children on the issue of health care http://www.youtube.com/watch?v=OETJFrpnwZc

Comment on Week 2: Meaning and significance of mathematics for non-mathematicians by MrSteve

SIMPLICIO: So where are we supposed to find all these teachers who can guide them on their “mathematical excursion”?
MrSteve: Good question, that is one problem I struggle with. There have been great math teachers and curricullums. We need to find one that can scale.

SIMPLICIO: But all the kids are using iPads and iPhones go to where they are?
MrSteve: iPads and iPhones are “consumption devices.” They are not designed as tools for construction and exploration of ideas. Actually more accurately the software on them (and partly limitations of the screen sizes and the user interfaces) limit their uses. That said they are tools and like any tools (and content) they are double edged and can be used for good or “distracting ourselves to death”

Comment on Maths textbooks by Esther Allerton

Richard Feynman told a wonderful story about math textbooks. He was one of a group of people who were supposed to give a score of 1 to 10 to a selection of math textbooks, the idea being that the book with the highest average score would be the one chosen for that state’s standard math text. All well and good, but one of the books was blank. The testers who noticed it didn’t give it a score. Those who just automatically issued a 10 to everything never noticed that it was blank. The book that was chosen had an average score of ten, which sounds great, until you realise it was blank.

Sorry can’t help you on the IGCSE book choice – we’re using a standard GCSE one.
