Clyde Greeno posted Oct 20, 2012 12:21 PM (GSC's remarks precede and are interspersed):
It is refreshing indeed to read a counter-argument that is based on a rational examination of the matters in question. I am not able to (nor am I qualified to) judge the 'scientific validity' of Jo Boaler's work in 'Education Research' - as I have read nothing by her except "When Academic Disagreement Becomes Harassment and Persecution"; also, in current circumstances, I am not in any case able to investigate and judge 'scientific validity' of a piece of 'educational research'). Hence my remarks are based purely on a reasoned examination of Clyde Greeno's remarks in his message:

(I believe a good case might be made to broaden this assertion to include "all scientific theories" as well, but I have no references to provide for this; could you perhaps provide some references to 'scientific theories' that have developed NOT through some scientific questions or the other?). > > In the macrocosm, what is the scientific theory which > Boaler's works serve to advance?

I've not examined enough of the literature to be 'universally skeptical' abut ER: but it is entirely possible that you are not incorrect to be skeptical.
However, I do not agree that your skepticism precludes any serious investigation by you: in fact, it is probably the right attitude to have towards ANY claim of scientific advances - with the proviso that it is NOT a 'blanket skepticism' one should hold, but a 'healthy skepticism'. Of course, we do need to define both terms 'blanket' and 'healthy' to describe the quality of the skepticism in question (but I shall leave that aside at this time!) > > (2) Link Research to Relevant Theory > Not just to "relevant theory", but specifically to > the *encompassing scientific* theory.

In fact, I'd believe that she'd do well to ask you to investigate her findings (as a counter to the Milgram/Bishop findings. Because you have been skeptical, any positive findings from you would have special value). > > About Hake's, "Yes!": If Richard knows of some > evolving scientific theory to which Boaler has > contributed to to its development, I'm all ears ... > not so much because of her own contributions, as > because of the earthshaking importance and > significance of any such scientific theory. > I'd agree with the above if you would remove the (perhaps pejoratively intended) adjective 'earthshaking'. A piece of research does not have to be earthshaking in order to be important - and Jo Boaler's work might well be important. So far as I know, she claims to have demonstrated:
"...students who engage actively in their mathematics learning, rather than simply practicing procedures, achieve at higher levels".
To me the above seems obviously true. If she has actually done so, it is an important finding (if this assertion is being denied by the 'traditionalists'). I frankly lack the resources or time to investigate Jo Boaler's research.
I have found that Professor Bishop has consistently displayed the most unscientific of attitudes in his interactions with me at this forum. If he has displayed the same attitude in respect of his critique of Jo Boaler's work, then he deserves to be criticized for that. Professor Milgram has not, in my opinion, done himself any favors by associating himself with Professor Bishop. > > Methinks > that, unfortunately, Richard's "Yes!" stems not from > science, as such, but from his other instructological > information which has yet to congeal as a bona fide > e science. > This is possibly true. > >If so, Boaler's "findings" (whatever her > methodology) might somehow help nurture the > development of such a science.

[while it certainly NOT acceptable to state "I am illiterate!"]. In my opinion, for a literate person to state "I'm useless at math!" indicates some serious societal defect.
I'd generally accept much of Clyde Greeno's reasoning. However, the way Professors Milgram and Bishop have gone about their 'demolition job' on Jo Boaler is not, in my opinion, an appropriate way to critique or disprove her findings. The underlying issue here is the unprofessional and 'unprofessorial' attitudes of Professors Milgram and Bishop.
By the way, I'd love for you to cast your skeptical eye on my development 'One Page Management System' (OPMS) [which has considerable significance for, amongst other things, ER - and for education as a whole]. I attach herewith a list of some Missions for the OPMS (attempted successfully and unsuccessfully; still ongoing; proposed). Some of these proposed Missions could be, I claim, 'earthshaking' (when they come to be). Some information about the OPMS is available as attachments to my initial posting at the thread "On realistic and practical tools for the US education system..." - http://mathforum.org/kb/thread.jspa?threadID=2405705.
In conclusion, I'd answer the question in the title of this thread as follows: "Education Research" (as it should be practiced) is certainly "Scientific Research!"
