Researched Maths In Addition To Scientific Discipline 2016

People rave close Tom Bennett's researchED events together with then I was rattling pleased when he announced a conference devoted to maths together with science. I am a staunch advocate of dependent champaign specific evolution for teachers - I notice that generic preparation (the type delivered at schoolhouse INSETs - 'how to differentiate', 'how to create AfL', 'ideas for revision') is rarely of instantly relevance to maths teachers.

The programme for researchED was outstanding - interesting sessions, first-class speakers together with a good structured day. Unfortunately I had to locomote out at 2pm to acquire to a marriage ceremony together with then I was entirely able to attend 4 sessions. I've provided summaries of those sessions here.

Thankfully I had the chance to briefly grab upwards alongside a lay out of Twitter friends throughout the day. This effect marked the start of a busy conference flavour for me - over the side yesteryear side 2 months I'll endure speaking at 4 events - outset upwards is LIME Oldham on 20th June where I'll endure speaking close quadratic methods.

Comparing examination questions
The outset session I attended was run yesteryear representatives of Ofqual. They spoke close their operate inwards comparison the difficulty of examination questions, together with the sources of bias inwards judgements made.

Remember when the novel GCSE sample assessment materials were outset released yesteryear the examination boards? Many maths teachers said that the Edexcel papers were notably harder than the AQA papers. After Ofqual had accredited the papers, concerns raised yesteryear teachers prompted them to create a report of examination enquiry difficulty. They asked 43 maths PhD students to create a comparative sentence of 2,150 questions. Their job was to approximate 'Which enquiry is the to a greater extent than mathematically hard to answer fully?'. In each illustration the PhD students were given 2 questions side yesteryear side on a enshroud together with had to betoken the to a greater extent than hard of the two. Later these questions were attempted yesteryear 4,000 pupils (presumably these pupils had truly been taught all the topics they were existence tested on - it would endure pointless to plow over pupils a enquiry on a quadratic inequality if they hadn't all the same been taught that topic).

The questions shown below are those that pupils establish harder than the PhD students expected. Here nosotros get got a multiple pick decimal/percentages enquiry together with an venture of operations question. People generally, together with oft incorrectly, perceive multiple pick to endure easy.
The circle theorem enquiry shown below is 1 that pupils establish 'easier' than the PhD students expected. Of course, this doesn't hateful this is an 'easy' enquiry - it could good hateful that teachers get got anticipated the challenges together with taught this theme well. At the halt of the session person suggested that this indicates that teachers are doing something right, a comment which was laughed off but is truly rather important.
I was frustrated yesteryear the determination to purpose PhD students instead of experienced teachers inwards this report - certainly teachers get got a far ameliorate sentiment of what pupils volition notice hard. Ofqual realised this too, together with revised the procedure accordingly. Prior to accreditation of the novel scientific discipline GCSE, they asked scientific discipline teachers to undertake a comparative judgement. Interestingly it turned out that the scientific discipline teachers' judgements weren't equally 'accurate' equally nosotros powerfulness expect. Ofqual identified a lay out of sources of bias that powerfulness explicate the discrepancy. For illustration questions alongside a large discussion count were oft judged to endure to a greater extent than hard than pupils truly establish them.

I create wonder whether it is helpful to approximate a enquiry yesteryear but glancing at it - certainly 1 needs to consummate a maths enquiry to properly assess how hard it is. Twenty seconds a enquiry doesn't audio similar enough.

Influenza A virus subtype H5N1 similar projection volition endure undertaken over the coming months for the novel Knowledge Gaps' I wrote close my wish to larn to a greater extent than close how maths is taught at primary school. There seems to endure a disjointedness inwards the means things currently operate betwixt primary together with secondary. Jack Marwood is a primary schoolhouse instructor alongside a maths grade together with I attended his session '10 things you lot should know close primary maths'. The slide below shows the potential confusion arising from the purpose of 'remainders' inwards segmentation inwards primary school.
Jack recommended the operate of Hung-Hsi Wu at Berkeley, particularly The Mathematics K-12 Teachers Need to Know.

Jack's slides from his reasearchED presentation are available here.


I facial expression frontward to reading other bloggers' write-ups of the sessions they attended. It was rattling much 1 of those 'I wish to endure inwards 3 places at once' kind of days. Thanks to Tom Bennett together with Oxford University Press for an first-class event.

Finally, I must holler the venue! The University of Oxford Mathematical Institute is wonderful - facial expression at the beautiful Penrose Tiles outside. The edifice is named afterward Andrew Wiles, the mathematician who proved Fermat's Last Theorem. I had entirely been at that topographic point 1 time before, representing the Bank of England at a careers fair, together with I truly bumped into Stephen Hawking that day! Amazing. Maths is awesome, isn't it?
