Bob Newhart is one of the all-time great stand up comedians. He’s perfect at capturing the powerlessness of the little guy in a ludicrous world of hucksters. Newhart was huge in the early 60s but, despite the fact that most comedy dates really quickly, many of his routines hold up very well. His best routines are, maybe, Retirement Party, African Movie and Abe Lincoln vs Madison Avenue. And, since this is a maths blog, we have to make mention of Infinite Monkeys.

One type of educational horror that we haven’t yet written about are SACs, those internal assignmenty-examinationy things that make every second week of Year 12 studies a living hell. It is a tricky topic since SACs are school-based, often teacher-specific, and our primary goal is to attack inept authority. In that regard, schools and beleaguered teachers are in a weird middle ground, part victim and part villain, and they already have plenty of critics. Nonetheless, SACs are the sea in which students and teachers swim (or sink), and mathematics SACs are typically appalling; the overwhelming majority of mathematics SACs that we see are pointless, anti-mathematical, error-strewn blivits. So, something has to be written about such SACs of shit. And, we have a plan.
Our hand has been forced a little, however, by an email we received from a VCE student. The student is taking Mathematical Methods CBE, the trial version of Methods that uses Mathematica instead of CAS, and the student wrote about a recent Mathematica-based SAC at their school. We then asked a teacher at the school about the SAC, and they confirmed the students’ report.
This then is the students’ story, exactly as written to me.
I’m not sure of how many other students you know that are doing CBE methods but my sac today served pretty well to show how awful things can go, so a new perspective is always welcome right?
Starting from the top, we have school-provided laptops with Mathematica preinstalled. So we go in, and we have to utilise this thing called a palette which takes control of Mathematica (I have many complaints against the palette) and downloads the SAC from some remote server. No problems here right? Well, I’d imagine 200 people simultaneously downloading an item from a server would MAYBE just MAYBE cause some congestion in the network. Hell breaks loose here, a class has their file downloaded and enters reading time while the other 4 or so classes are in utter chaos. The downloader is failing over and over while also saying it succeeded. This goes on for a good half an hour before the teachers collectively decided that the sac would be rescheduled to Thursday. The class that began reading? Oh, they just stop. God knows what they could have done, taken photos of the sac with a snipping tool, copied the files over, the possibilities are endless. This whole thing is almost appalling yet terrifying because this is what I’ll have to do at the end of the year. I’ve got a load of other concerns, among the unending variety of methods to do a question with Mathematica and how an assessors report would assign marks, to which our official VCAA quiz provided pissant “solutions” that were often wrong.
Anyway, my slightly irritated take on the abhorrent state of the CBE system, which I thought may be interesting to you.
To that, the teacher at the school added the following:
[The former Head of mathematics at the school] made a deal with the devil and agreed to the school doing Methods CBE. I don’t feel the consultation process valued the feedback from myself and other teachers – it was always going to happen despite the misgivings of other teachers. I can’t help but think that my feelings on the issue is the reason I’m not teaching Maths Methods this year (for the first time in 9 years). There are many problems with this deal – it makes my blood boil. The current head of maths is a very decent guy and has done a fantastic job dealing with the mess he inherited.
I heard that the SAC was a disaster and actually saw events unfolding from afar – like watching a car crash in slow motion. Blind Freddy could have seen what was going to happen. As I left school, I saw the VCE coordinator and the current Head of Maths running around grim faced.
All of the student’s concerns are legitimate. Furthermore, the SAC was meant to run until 4.45 pm, so many students will have made alternative and inconvenient arrangements to accommodate this and now they have to do it all over again. Not to mention what it’s done to the stress levels of many students. Not to mention the time and resources that had to be expended re-writing the SAC. At every stage VCAA have washed their hands of CBE problems and left the school to do its dirty work, using the students as the guinea pigs.
1. The palette provided by VCAA had a bug.
2. The VCAA server failed. VCAA are trying to blame the school for both errors and no apology has been given. Re: The server fail. VCAA said that the school should have downloaded from the server prior to the SAC starting (which is not practical). VCAA are saying everything worked fine at the other CBE schools (which all have small student cohorts as opposed to our school’s cohort of over 200, which makes a big difference).
That’s it. Our own point of view is that SACs are all but guaranteed to be awful and Mathematica in the classroom is all but guaranteed to be awful. Here, however, those predictable awfulnesses are beside the point. The point here is VCAA’s Trumplike level of incompetence combined with VCAA’s Trumplike unwillingness to accept responsibility.
