CAS Calculators Casio Classpad 330

Sat with the CAS casio classpad 330 calculator today. OMG.. what a learning curve, to face 3AB MAS MAT and learning how to use this new bit of tech.

We tried to use it to assist in solving an investigation. Took 3 mins on paper. 5 mins to setup on the calculator and 1/2 hour to find out why it wasn't working.

I think I'll need to post a few things on here about it as I learn more.

My advice to all - get the stupid thing out and start playing with it tonight if you haven't started already.

The first bit of useful content for learning the tool I've been given is The videos are a bit of a help and look quite good. They may assist if you can take the students to a lab after introduction of a new topic.

The consensus is to get proficient to at least the level of graphics calculators and then the rest will follow as everyone gets more aware of their capabilities. I certainly miss not having certain buttons at easy range that I am familiar with such as trig functions and sqrt keys. I do like fiddling with technology though so I don't see it as too much of an issue for me.

oh.. and Rom Cirillo from the Curriculum Council (who has been a rather nice bloke throughout the NCOS fiasco).... of course if you ask us to vote whether we want CAS calculators now we are going to say yes... WE HAVE ALREADY TOLD PARENTS THAT THEY HAVE TO GET THEM FOR NEXT YEAR BECAUSE YOU/CC SAID THEY WERE REQUIRED, YOU DILL! Great idea to shift blame to teachers for any costs to date by shifting responsibility for calculator selection in 2AB back to schools. What happened to the equity issue for 2CD students next year (not to mention the need to buy a $175+calculator for use in 3 terms year 12)? When CC people (at the PD) were questioning the need for these calculators at all, I wonder how much thought has gone into the need for this planned, staged, implementation by CC (it seems another opportunity to ditch teachers into a hole and see what comes out). Is there any actual measurable improvement in maths by students expected by using these tools (especially as complex calculators are rarely used out of school)? Does anyone know where the broom is?
