The conditions then, were clearly not optimul (or even good for that matter) and caution was IGNORED if you are using words like corruption/shoddy quality control/over-confidence to describe the climate around the shuttle's failure. I feel that if we decide to launch the NCTM standards as set forth in the Framework and we fail to give adequate support (shoddy quality control) to teachers who are to implement these standards, then we may end up "losing" many more math students than did we astronauts.

Yes, but analogies are only rough comparisons and so no one need die in class to consider my analogy. I have seen some students "die" mathematically in algebra courses due to the lack of structure....I have seen some "die" because of too much structure.
[[[[[[[[[[If you're arguing that the NCTM reforms are ill-founded and hastily implemented, let's hear some evidence]]]]]]]]
I don't believe that the most recent NCTM reforms have been "implemented" as of this posting so I can't give any evidence as to their being HASTILY implemented. The NCTM reforms are in writing and are suggestions that teachers MAY use...but their implementation has not yet been decreed. The only evidence I can site on PAST "new math" reforms being hastily implemented is what I read on this list and hear at educational workshops....that being that there was not nearly enough support given to instructors about how to implement these new math reforms. There wasn't nearly enough time given to instructors to absorb the methodology. As to weather the reforms are ill-founded....that has been debated on this list quite extensively. Some feel that the reforms have been manufactured due to a changing social climate in this country. Suddenly more and more kids are coming from homes that are low on motivation and high on substance/child abuse. More and more kids are having to work after school (the energetic ones) and more and more kids are playing computer games/watching TV/hanging out in gangs instead of putting in any homework time (the lazy ones). With the social decline experienced by the American family along came a sharp decline in students taking responsibility for their own education. Because of this, (I believe) some folks said it was time to reform math instruction. So....I am not saying that conditions have to be perfect to instigate reform.....but perhaps if we look at these CONDITIONS we will see that we should be spending more time exploring the causes of/remedies to these conditions than working around them with reform that could very easily land on the same deaf ears presently listening to the old methodology.
