2+2 != Maths

What do you mean I don’t need a formula?

Welcome,

I have had a very hard time introducing concepts based assessment (aka standards based grading) to my Year 11 General Maths class this year. I have always tried to teach concepts and so assessing this way was a very good fit. I’ve also tried to emulate some of Dan Meyer’s “be less helpful” ideas. To say it’s been a tough task would be an understatement.

My students are all invested in “formula, formula, formula” and copying worked examples from “cheat sheets” onto test papers – these tasks they can do, but ask them to actually think about something, anything, and they run for the hills.

Imagine my pure joy, then, when during marking of my most recent concepts test I came across the following.  Here is a student who is complaining about having no notes, no formula and yet they were able to think the problem through and get the correct answer (albeit with the wrong units)

If only more of my students would actually engage their brains and take a chance to apply some of their knowledge to their work.

Contrast the above to this second student who has clearly found the right formula and put the numbers into the correct spot, but can’t use a calculator properly or recognise that the answer the calculator has given them is totally wrong.  This is a student with very little understanding of the question or of the concept.  A “formula” driven student who has probably experienced some success in the past but is totally out of sorts when asked something outside their comfort zone.

Clearly the first student has a better understanding of the concept and the processes involved, and I would like to think that if a few more students in this class could make the same effort then they would start to see Maths in a different light.

Unfortunately, many of my students would rather expend their efforts attempting to get me to “teach them real Maths”.

Cheers,
Chris.

P.S.  I must admit to having a chuckle over this student’s comment about the photocopier. 🙂
