## The Titcombe Maths Test

Many years ago, when I was a physics teacher, I gave a test like this to my top set Y11 GCSE students. The results were very poor. I have since shared this test with some current maths teachers. They have told me that their GCSE maths students would struggle with it because the topics tested are not specifically on current GCSE maths syllabuses.

I was never a proper maths teacher although I was on occasion been pressed to teach maths to fill timetable slots.

I suspect that current Y11 maths students would have problems with my test. What I would really like is to give it to Y12 students including those with GCSE C+ grades. It would be interesting to see how these students fared and whether those with B+ grades can sail through it, as they should be able to.

I was reminded of my maths test by the BBC 2 series broadcast in September 2015 featuring a Hampshire school, which carried out a very brave experiment dividing a year group into equal cohorts, one of which was taught 'normally by the school's teachers. The other cohort was taught by a team of expert Chinese teachers.

This experiment deserves a post of its own as there is so much to learn from both the experiment itself, the attitudes of the Chinese and UK teachers to each other and to the students, and from the outcome. I summarise this as the Chinese teachers having enormous problems with the behaviour of the students, which they put down to the UK welfare state mitigating the deservedly harsh consequences of school failure for UK school leavers. Despite this, and some truly awful lessons shown in front of the TV cameras in all their horror, when both cohorts were given the same tests at the end of the experiment, the students that had the 'China School' experience scored higher.

There are a great many questions that need to be answered before reading too much into this outcome, however, there appeared to me to be one characteristic of the teaching approach of the Chinese teachers that may be relevant to the 'Titcombe maths test'.

It appeared that the Chinese teachers placed great emphasis on securing the understanding of the most basic concepts, like those in my test. My test appears to reveal some very common basic weaknesses, such as students being insecure in their grasp of place value in the decimal number system (let alone with other number bases) and with performing functions involving zero and one.

I am posting this because it seems to me to raise a number of interesting questions and issues. I hope some teachers, retired and current will comment.
