[Phys-L] Maximum Physics Lab Enrollment in Argentina

[Carlos Alberto Vasquez <carlosalbertovasquez@YAHOO.COM.AR>]

Dear Sirs: It is very interesting for me hear about the maximun erollment in
Physics Lab. The situation in my country, even in private secundary school,
is that there is no maximun Physics enrollment number because the most of
our studients has no Physics Lab (or Chemestry or Bilogy). The Science
laboratory is though as an "aditional" to the classroom teaching. The worse
thing is that the autorities have no conciencius about this failure. I think
that this issue is very important in USA, and it is one of the main reason
for your succesfull as a big nation. Please do you have any literature to
support this and to grow up the conciencius in our local educational
autorities?.
Thanks to you in advance.
Sincerely.
