Picture: This screenshot in 2005 suggests David Penberthy's posture as honest broker on MySchool issues is a bit strained.
We wrote recently of 'foolish' big media and big politics parading their non sequiturs on the value or not of the new My School website. We used the example of a 135 million strong yet frivolous Youtube posting to prove high web hit rate is not probative of serious content. The specific Youtube 'Charlie bit my finger' was indeed cute and a celebration of humanity but entirely frivolous.
News Corp golden web-ster David Penberthy who runs Punch (or is that Punchy?) was paraded in two page press feature yesterday in the Sydney Daily Telegraph print version, with a sledge on the teacher unions: In short the union is just protecting dud teachers is the claim.
Worth unpacking this assertion to show how poor Penberthy's arithmetic must be.
How can a single school average over say a 1000 student school show which teacher is dodgy? The proposition is a non starter - because it's 'a school' appraisal not an individual teacher assessment. Indeed it's not even a school assessment, it's a student assessment in all their diversity and systemic disadvantages.
A global number for all students in a school to measure a single teacher? Mmm. So much for the 3Rs and basic mathematics.
All Penberthy is parading is the ideology of his anti union News Corp employer.
