Historical Development

 The story starts in Karlsruhe, 1976 • ICME 1976 – International Congress on Mathematical Education  [chance?] meeting between Peter Holmes, Vic Barnett & Fred Eicker • • Vic : – Head of Department in Sheffield Peter : – Director of Statistical Education Centre  Discovered common interest in Statistical Education, particularly at school level 4

Dortmund 227, Sheffield 4; Dortmund, 8/3/2004

 I recall Vic reporting later in Sheffield that he had met a Professor from a German University which had a new Statistics Department

&

 This Department

‘felt lonely’

since it was the only

real

statistics department in the country, so had suggested forming a link with Sheffield.

 Various meetings and visits followed:  Particularly: – • Vic Barnett and Clive Anderson • Siegfried Heiler, Fred Eicker, Wolfgang Urfer  A draft proposal was drawn up & signed on 11 November 1979  A formal

Programme of Academic Cooperation

was signed in Dortmund on

8 August 1980

 The first six students from Dortmund came to Sheffield in October 1980 • & every year from then until 2002  I (& family) spent three months in Dortmund in Spring, 1981  Wolfgang & Barbara Urfer came to Sheffield in Spring 1981 for a month – [kindly lending us their flat…]  In 1982 the first Sheffield student came to Dortmund • & the second in 1994, the 3 rd in 2000, 4 th 2003!

Benefits

 Clear benefits to participating students  Many participants now in major positions  Clear personal development • (especially noticed in returning Sheffield students in last 6 years) • Maybe partly self-selection but not entirely 37

Dortmund 227, Sheffield 4; Dortmund, 8/3/2004



Clear benefit to Sheffield

 It’s a pleasure to have some of the

best

students from the

best

across Europe Universities  Good for ‘ordinary’ Sheffield students •

If they won’t go to Europe then I’ll bring Europe to them

 Provides a significant source of PhD (& MSc) students •

 Our Dortmund visitors particularly show our students different attitudes to study and different ways of approaching work  Especially good in collaborative data analysis projects 39  We particularly appreciate the courtesy when Dortmund students switch to English when talking to each other.
