One of the first overseas school trips I accompanied was to the American Association for the Advancement of Science annual conference. Looking back, I feel immensely privileged to have been able to work in a school that supported giving students in year 12 the opportunity to visit a world leading scientific conference.
Most of the material was way above the heads of even these academic high achievers, however I could see the value for them in pure inspiration. For many kids the days contained many lightbulb moments. Kids would be super charged with ideas that, while they may not have understood all the details, they could see how they connected to what they were learning in school. These were certainly intellectually high challenge events for a 17yo.
I remember, as an accompanying teacher, feeling like I was undergoing solid subject specific CPD and many of the workshops that I attended as a Masters-degree holding biologist were concerned with a topic known a pharmacogenomics. This was 2009, the Human Genome Project had concluded four years earlier and there was much discussion about the applications of this research.
Pharmacogenomics holds, crudely, the promise that essentially, one day, we will be able to have our individual DNA sequence read quickly, in a GPs surgery, and drugs tailored to our particular genome. That medicine can be tailored to us so that we all get treatments that are most effective for each of us individually.
There is no doubt that this is the way that medicine is moving, albeit slowly and it is likely that if the light’s don’t go out on civilisation we will see some version of this in the next 100 years.
Reading Robert Plomin’s Blueprint it was striking to read a psychologist begin to explain how 50% of the variance of intelligence within a population can be explained by genetics. This means that the biggest, stable, correlation of educational outcomes is with the DNA within an individuals genome. Plomin goes on to explain that the shared environmental influence of children attending the same school and growing up in the same family accounts for only 20% of the variance in school achievement (and only 10% at university).
This claim begs the question as to what are the implications for education if genetics is the best predictor of educational success?
As Plomin is keen to stress these predictions are probabilistic and not fatalistic. Just because genetics is accounts for 50% of the variance of educational outcomes, this does not mean that kids with the “right” genetic mix are pre-determined to do well, just that, on average, they will. He argues for going with the grain of genetics, and, in the case of parenting, working in a way that exposes children to opportunity but develops children alongside what they appear to be interested in.
I found many of these ideas fascinating and I am left with the question – will we soon be in the time of educational genomics? Will we be able to sequence our DNA and from the information have an insight into our psychology in such a way that we can tailor instruction to be optimal for us?
I suspect that the differences in the DNA and psychological make up in the 1st and 2nd standard deviations of the population will be so small as to make tailoring of instruction as effectively meaningless. The fact is, that children need, for a host of reasons, to be educated communally, and this creates a whole host of issues with regards to the personalisation of education.
Still it is an interesting idea..
