The relevance of normal distributions has been highlighted by Moore (1997),
and Cohen and Chechile (1997) who remark its role as a link between descriptive
and inferential statistics. In our research (Batanero, Tauber and Meyer,
1999; Tauber, Batanero and Sanchez, 2000) we study the teaching and learning
of that distribution, with the help of computers in an introductory course
of data analysis. Our theoretical perspective (Godino, 1999) considers
the meaning of concepts from an institutional and personal aspects and
describes different types of meaning elements. We analyzed the textbooks
directed to students in social sciences and identified the more common
meanings. Starting from this reference meaning, we designed a teaching
sequence based on solving exploratory data problems when students would
work in pairs with STATGRAPHICS. The analysis of the teaching sequence
served to described the foreseen meaning that would be used and the specific
meaning contributed by the use of computers.
