It means that a treatment found to be better in a randomised trial could be bad for some people but really, really good for others (e.g. men/women, different progression of the same disease). <br /><br />So my headline would be “Some Pericarditis Patients May Get Help”.<br /><br />(And I think I am saying something different to your causal/deterministic argument.)<br /><br />MPledgerhttps://www.blogger.com/profile/15845074140006920009noreply@blogger.comtag:blogger.com,1999:blog-4857051406259349751.post-69870922213408601842015-06-25T14:55:48.327-07:002015-06-25T14:55:48.327-07:00You seem to miss the fact that there are real chil...You seem to miss the fact that there are real children being harmed by this - those kids in school right now. Kids get turned off education if they slave away to learn stuff that gets them a "fail" when they take the test, that they lose trust in educators if the educators don't know what they are talking about. Education and the contest to get into the "right" college just becomes even more of process based on luck, of being on the right side of measurement error.<br /><br />So we forget about the kids who got the raw end of the stick by being born at a time when they got these poor materials because ... it might be able to be fixed, sometime, maybe, and for those schools who are able to afford the updated materials. <br /><br />(I seem to be failing at negotiating the "publish" process. Excuse the multiple similar posts, if the appear.)MPledgerhttps://www.blogger.com/profile/15845074140006920009noreply@blogger.comtag:blogger.com,1999:blog-4857051406259349751.post-18830556077328972722015-06-25T14:11:34.370-07:002015-06-25T14:11:34.370-07:00Kevin,

EngageNY and CC in general are the product of a top-down, rapidly implemented system with no effective feedback mechanisms. This is why mistakes like "negative times a negative is a negative" can go uncorrected for so long. <br /><br />In other words, we need to get to the acknowledge-the-problems phase before we can get to the fix-the-problems phase.Markhttps://www.blogger.com/profile/14705408455380402571noreply@blogger.comtag:blogger.com,1999:blog-4857051406259349751.post-18799927178406570612015-06-25T07:38:49.499-07:002015-06-25T07:38:49.499-07:00(cross-posted at West Coast Epidemiology blog)
On...(cross-posted at West Coast Epidemiology blog)<br /><br />One perspective that I haven't seen yet in this debate (and the Feynman quote is a good example of what I'm criticizing) is whether these are fixable errors (which they are), and whether they will be fixed (which we can't know yet).<br /><br />For some reason in technology we're prepared to accept that initial products are often very flawed and only get usable/interesting after a few revisions.<br /><br />In the case of curricula and educational innovations, the conclusion seems to be: these are wrong and so the people who made them are stupid and so we need to throw them out and start over. <br /><br />Looking at the arc of educational reform in the last 50 years, I can't say that this approach has worked well.<br /><br />So I'd like to encourage in these posts to be slightly more constructive and consider: What would it take to fix this?<br />kevinmilhttps://www.blogger.com/profile/07883363610015514812noreply@blogger.com
