"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.
