The word of education is awash with data – particularly testing results. While I personally have significant reservations about both the use and usefulness of much of this data, due to a combination of the harm it can do to students, teachers, parents and schools as well as the often unsound assumptions upon which it is based, it has to be acknowledged that not everyone shares my views. However, I will put my concerns aside for the moment and share this video explaining the biggest number cruncher of them all – the PISA testing program. It is done in the style of the poplar RSA Animates series and surprisingly, despite being essentially an advertisement for PISA, it is entertaining ... and also contains some though producing insights – hence the posting here.
Most educators are familiar with the Programme for International Student Assessment – otherwise known as PISA. Some may not be aware that PISA was actually conceived and is managed by the OECD – the Organisation for Economic Co-Operation and Development. It often passes unnoticed that this body is not primarily concerned with education. As well as providing a vehicle by which the school systems of participating countries can be ranked, PISA has made some observations based upon educational practices and results from around the world.
Many of these are now entrenched in the educational psyche – for example, girls tend to outperform boys all over the world in literacy while the reverse is true for mathematics. An equally “obvious” fact, but one which is significant to have confirmed at this level, is that home background is a major influence on student success. It is nice to have this confirmed by PISA (given the economic slant of the OECD) – perhaps people will bear this in mind when evaluating school performance.
There are other “obvious” findings that it is pleasing to see confirmed – that students with fewer books at home are less likely to read. An associated fact presented in the video is that children from “advantaged” families hear 30 000 000 more words over the course of their school years than students from “less advantaged families” ; you read correctly - 30 million. The impact of this upon literacy performance need not be expanded upon here. The fact that a conservative organisation like the OECD confirms the impact of home background on student success is significant – and well worth remembering during the next phase of “teacher bashing”.
Some other areas mentioned in the video include;
Perhaps the most interesting observation mined from the PISA data set was this observation – that students from “less advantaged areas” that attended schools situated in “more advantaged areas” tended to do as well as their classmates. Let’s unpack this a little – in this video PISA confirm that home background impacts significantly on student learning...but then indicate that students from “less advantaged” areas can outperform their neighbours and match their more advantaged classmates by attending school in more “advantaged” areas. If this is true, and given the statistical rigour of PISA I’d suggest that, numerically at least ,this is a valid finding, then schools need to examine how this is possible. The implication is that schools may be doing things that counter unhelpful social issues.
It is tempting to assume that the schools in “advantaged areas” are doing things that do not occur in “less advantaged areas”. If this is true then the solution is obvious – mimic the practices of advantaged schools. However, this is simplistic – there are high performing teachers and outstanding educational practices in “less advantaged” areas which do not produce the same test performance as their more wealthy equivalents.
Perhaps we should consider some of the non-tangibles of teaching and education – things that PISA can’t measure. Why are these students attending schools “out of area”? Does this display some perception and ambition on the part of the parents? Is this transmitted to their children? Is this reflected in the work habits of the young people concerned? So... following this train of thought, do the statistical findings of PISA support the wide spread “truism” that family values and attitudes towards education are key variables determining success at school? Is achievement more to do with attitudes than with ability?
The video runs for about 12 minutes – but the contemplation of the issues it raises will last much longer.
