Dear JEM interested parties,

thus far we have not found it so I am hereby launching the quest for a repository of mathematical competencies.

Once could say that national curriculum standards contain so but this is done a very informal way so we, in intergeo, are looking for something more repository like.

thanks in advance

Is there any interest on JEM installing a connexions server?

Is there any interest in JEM hosting a WebWorK server for test purposes?

Gosh!

This has sparked a random thought: If answering a mathematics question is used as this test then we have a couple of tricky issues to resolve.

(1) a CAS is often much more accurate than a person with a complex "symbol-pushing" calculation.

So, what happens if the computer incorporates a CAS as an attempt to fool this test?

(2) people are nororiously poor at basic logical reasoning. Have a look at the "Wasson Selection test" as a prime example.

In using technology to teach and to lecture, one is bound to make mistakes - whether it is the style file or the software or the animation not working, I am sure we all experienced some "demo effects" that have taught us lessons. I will start with mine:

• Green is a bad color for projectors not only it is one of the major combinations in colorblindness (red-green) but it is also very hard to read when the background is light, e.g. white.
