I can't find this ZDM article:

Vinner, S., & Hershkowitz, R. (1983). On concept formation in geometry. Zentralblatt für Didaktik der mathematik, 83(1), 20-25.

Could you help me?

I was searching in some sites, but no success.

For example, in this one, it isn't available: http://www.emis.de/journals/ZDM/zdmcont.html

    $\begingroup$ Did you try contacting Vinner and/or Hershkowitz directly? Alternatively, you might check who recently cited the paper to see if one of these authors has a copy that can be easily communicated. (I did a reasonably thorough search for it just now and came up with nothing...) $\endgroup$ Dec 9, 2015 at 17:41
  • $\begingroup$ I can't seem to find it in any of the online resources I normally search. Do you have access to inter-library loan resources through a university library? $\endgroup$

Finally, the author posted it in www.researchgate.net


Thank you to all.

    $\begingroup$ I hate to be the bearer of bad news, but that article is not the one you were asking for. Although the researchgate page has the right name, the actual PDF linked there has a different title, different page numbers, and does not have Vinner as a co-author. $\endgroup$
