Uncertainty principles

In the lead up to eAssessment Scotland where I will be speaking later this week, I offer some thoughts on assessment. There are some things you just can't assess. One is creativity. Another is character. Yet another is how tenacious or resilient a student is - do they persist in their learning despite the odds? Attempting to measure such things actually makes a nonsense of assessment. It's a bit like over-analysing a joke. What makes a joke funny? Is there a formula involved? Look at it too closely and it's no longer funny. It begins to disappear in front of you as you stare at it.

In 1927 Werner Heisenberg proposed a theory of quantum mechanics that became known as the Uncertainty Principle. In essence says Heisenberg, you can measure the position of a particle, or you can measure the future momentum of the particle. What you can't do is measure both at the same time. The more precisely one property is measured, (say the Wikipedia article) the less precisely the other can be controlled, determined, or known. Applying this outside of particle physics could be problematic, but let's try (because we're all made up of particles).

So you want to assess creativity? What are you actually trying to measure? A child's natural imagination? The creative outputs that are a result of that imagination? The value of their creativity in relation to that of the rest of the group? Against your own creativity? Against the standardised norms of the creative expectations of the entire society perhaps? Oh dear. You can identify that a child is talented in a particular area and their art is easy on the eye. They are good at painting. They have a propensity to be able to play a musical instrument pleasingly. Can you attach a value to it though? So what about Pablo Picasso? Or Karlheinz Stockhausen? Picasso wasn't particularly pleasing on the eye, Stockhausen was not easy to listen to. Although not everyone agrees with that last statement - even if they don't understand the art of the music - few would dare to suggest that Picasso and Stockhausen lacked creativity. Creativity is a very subjective thing, so should we attempt to assess it?

If you try to measure the current state - the effects of creativity on your emotions, the atmosphere, the ambiance of the experience, you will not discover where the creativity is leading - the message, the genre (sometimes) the theme. What are we doing with assessment of learning in our schools? Are we measuring the worth of the learning, or (as is inevitably the case) the worth of the individual? If we do the latter, we are betraying the trust of the child, because they will own that grade for the rest of their lives, citing it on every CV and job application form they complete. Is this fair? Is it fair that the grades they are awarded do not reflect their personality, their creativity, their tenacity, their resilience, their uniqueness? Standardised Testing and end of term examinations are absolutely unfit for this purpose. They are great for testing the recall skills of students, but useless in finding out more meaningful information about the knowledge and skills of the individual.  And yet we measure children's worth in exactly this way. Unfortunately, in this society that is what seems to count the most. Unless we value creativity, character and resilience (and resist measuring them), we will only create uncertainty in the minds of the young people who are in our charge.

"The person who scored well on an SAT will not necessarily be the best doctor or the best lawyer or the best businessman. These tests do not measure character, leadership, creativity, perseverance." - William J. Wilson
