Computers checking mathematical proofs?

Computers checking mathematical proofs?I suppose proofs could be computer generatedBut unless there's a readable printout, it's only been proven to the computer. Likewise, I have no objections to computer checking of proofs prior to publication with the understanding that it's akin to spell checking. The important thing is...

Enough already with the Luddite schools

Enough already with the Luddite schoolsI think middle school is better for tech than primary.I would rather see hand written reports up to and including 4th grade. Technology is great but so far cognitive scientists have not created a device that rivals the human brain. If you don't develop all...

Hardcore math at the speed of the Net

From its inception, the Internet has been about connecting researchers and research institutions to each other (and, of course, about national defense). As the Web continues to explode, though, it's interesting to see how new generations of researchers work, collaborate, and criticize online. A particular example...

The Mathematics of RAID-6

RAID-6 supports losing any two drives. The way this is done is by computing two syndromes, generally referred P and Q. The algebra used for this is the algebra of a Galois Field, GF(28). A smaller or larger field could also be used, however, a smaller field would limit the...

So just what is this RTI thing anyway?

RTI stands for Response to Intervention. It's a relatively new model for early identification of students with special needs and for providing ongoing services to students based on significant data collection. This is one area where educational technology is both useful and utterly necessary, providing the tools for...

Dumbing down our math tests?

The BBC is reporting on a trend in UK standardized math tests towards "easier, shallower and less demanding" examinations. Here in Massachusetts, I was working with our school psychologist to identify new interventions for special education students based on their standardized test scores. However, as she pointed out,...
