“The kids are unaware of the huge digital footprint that their parents have signed them up for.”
instead of filing into a gym hall to write in silence under a ticking clock, the ACT Government wants to leverage big data to keep a “minute-to-minute” pulse on how students are learning.
“Wouldn’t it be wonderful if at any point along their educational journey, students were able to get really responsive feedback? Technology needs to enhance learning,” Mr Willis said.
The real issue underpinning the controversy is the misuse of NAPLAN data. It was never intended that NAPLAN data would be used for fine-grained comparison of students.
The MySchool website has contributed to the misuse of NAPLAN data. For example, the scores from the site are being used to make comparisons irrespective of the “error bands” that need to be taken into account when making comparisons. People are ascribing a level of precision to the results that was never intended when the tests were developed. The test was never designed to be high-stakes and the results should not be used as such.
When people challenge the “validity” of the NAPLAN test, they should be challenging the validity of the use of the results. NAPLAN has a high degree of validity, but we need to understand it better and use the results in a more judicious and defensible manner. The correct use of NAPLAN data is a major issue and it needs to be addressed as a matter of priority.
Some tracking scripts may be harmless. But others are designed to recognize I.P. addresses and embed cookies that collect information prized by advertisers.
Google’s DoubleClick ad trackers, for instance, are commonly found on school pages that host YouTube videos, like the Community Website Introduction video on a school site in Massapequa, on New York’s Long Island. The trackers tee up videos containing advertising on the school page, once its own video finishes playing.
I have reflected upon this topic elsewhere.
I am probably wrong. Time will tell.
More recently, Yves-Alexandre de Montjoye, a computational privacy researcher, showed how the vast majority of the population can be identified from the behavioural patterns revealed by location data from mobile phones. By analysing a mobile phone database of the approximate locations (based on the nearest cell tower) of 1.5 million people over 15 months (with no other identifying information) it was possible to uniquely identify 95% of the people with just four data points of places and times. About 50% could be identified from just two points.

It’s Not Just What We Tell Them. It’s What They Infer. Many of us seem to think that “personal data” is a straightforward concept. In discussions about Facebook, Cambridge Analytica, GDPR, and the rest of the data-drenched world we live in now, we proceed from the assumption that personal data means something like “data about myself that I provide to a
Yes, we should be very concerned about putting direct personal data out onto social media. Obviously, putting “Democrat” or even “#Resist” in your public Twitter profile tells anyone who asks what party we are in. We should be asking hard questions about whether it is wise to allow even that minimal kind of declaration in public and whether it is wise to allow it to be stored in any form, and by whom. But perhaps even more seriously, and much less obviously, we need to be asking who is allowed to process and store information like that, regardless of where they got it from, even if they did not get it directly from us. source
Golumbia says that governments need to get on top of issues associated with data, because the public is struggling.
Keeping in mind that spirit of doing necessary maintenance, I recently did something I’d thought about doing for years: I unfollowed everyone on Twitter.
In a world where our data is the new oil, I’m interested in any way that I can help level the playing field, and seeing how we can put more control back into the device owners hands. Allowing mobile phone, wearable, drone, automobile, and other connected device owners to aggregate and monetize their own data in a personal or professional capacity. Helping us all better understand the value of our own bits, and potentially generating some extra cash from its existence. I don’t think any of us are going to get rich doing this, but if we can put a little cash back in our own pockets, and limit the exploitation of our bits by other companies and device manufacturers, it might change the game to be a little more in our favor.
As digital culture becomes faster, higher bandwidth, and more image-based, it also becomes more costly and destructive – both literally and figuratively. It requires more input and energy, and affirms the supremacy of the image – the visual representation of data – as the representation of the world.
