Not much interest in what teachers and principals think about My School

Not one minister, shadow minister, director-general of education or senior officer from the Australian Curriculum Assessment and Reporting Authority (ACARA) attended the National Symposium Advice for Ministers and ACARA on NAPLAN, the use of Student Data, My School and League Tables last Friday.
I guess they all presupposed the symposium would tell them to dump the My School website and hide the results of NAPLAN tests from the public. Be surprised. The main message from some of the speakers was just about the opposite.
The symposium was a joint effort by the Australian Government Primary Principals Association, Australian Secondary Principal’s Association and the Australian Education Union. This probably explains why no-one of either political or bureaucratic prominence attended.
And don’t mention the election ...
But I was pleased to spend the day listening to some of our most eminent education academics give their opinions even if the pollies and DGs were not.
Associate Professor James Ladwig from the University of Newcastle said we need more information not less. In particular we need to know more about what happens within schools and why some classes, groups and students out-perform others. We know student background makes a difference. We know quality teaching makes a huge difference. We also know there is no low achievement from children from any background in high quality teacher classrooms. But we don’t know enough about how this works for groups and individual children throughout their schooling and especially what is happening in Australian classrooms.
Ladwig said instead of concentrating on differences between Australian schools - that actually only accounts for 10 to 15% of the variance in student achievement - we should be finding out more about what teachers are doing within Australian schools (that can account for 40 to 50 % variance).
One teacher at the symposium told us all how upset he was with the My School website publishing the number of Aboriginal students at his school. He said he emailed ACARA asking why such information was published on My School and he did not get an answer. He said he then re-emailed the question every few days increasing the font size each time. Eventually he got an answer that he said was “very unsatisfactory.”
Ladwig said the reason such information is on there is because it is an indication of disadvantage. There is a big gap in achievement in literacy and numeracy between Aboriginal children and children from other backgrounds. The larger the number of Aboriginal children at a school, the bigger the gap.
A clear message from professor Alan Luke, from the QLD university of Technology, was there is nothing wrong with collecting data on school performance and publishing it, nor the fact that we are measuring these things. What is wrong is what ACARA is doing with that data on My School and the fact that ACARA is not allowing researchers to look closely at what it is collecting and how it is being used.
Apparently several researchers have asked ACARA for the raw data it has collected on family backgrounds for example so they can check the validity of the ICSEA measure of educational disadvantage, but ACARA has so far refused to release it. So much for the transparency agenda there.
Highly respected researcher Barbara Preston put a very convincing argument that selective schools and private schools were advantaged by the ICSEA measure. This makes looking at the like school comparisons on My School a problem - with selective schools and private schools being compared much more favourably.
Associate Professor Margaret Wu from the University of Melbourne pointed out each of the NAPLAN tests consisted of only 40 questions and the margin of error in the results can be as much as 12%. That is if a child did three or four different tests in the same subject they could get three or four different scores. So for example a score of 70% could mean as wide a range as 58% to 82%. Such a range means the NAPLAN results are not very good for making comparisons between children or for judging whether they have improved or not between tests.
On the other hand it is valid to use school averages to make comparisons Wu said. However the way My School does this produces the worst league table of all - because it uses colours (red for below average, green for above, no colour for being at the average) therefore indicating that schools have failed.
I will tell you more about the papers presented at the symposium in the next few weeks. If papers are posted on line I will let you know. |
