Talk of Eric Bachard (lead of the OpenOffice.org Education Project) and Morgan Magnin (Associate Professor, École Centrale de Nantes) at the Libre Software Meeting 2009 (http://2009.rmll.info/) During academical year 2008-09, a group of students from Centrale Nantes worked on the integration of annotation features in the slideshow module of OpenOffice.org. Two of them (Olivier Girardot and Frédéric Gélot) have become official OOo developers and interact with the other members of OOo team (like Thorsten Behrens). This talk summarizes the fruitful collaboration between Centrale Nantes and OOo Education project and gives guidelines for the contribution of students to free software developments.

3. Why free software in education?
Free software is not only a technical alternative
to proprietary solutions, it promotes values such
that:
Freedom
Cooperation
Security
Durability

for success
● Education environment willing to contribute to
free software
● Motivation of both students and OOo teams
● Win-win relation for every actor:
– Education: real-life projects with added value
– Students: contribute to a famous software
– OOo: perspective of contribution to new
features

13. The 3 main objectives of
Education Project :
●
Create a network of teachers using
OpenOffice.org
●
Provide a space for exchanging pedagogical
contents, under free file formats
●
Teach, provide young (core-)developers to write
code for OpenOffice.org

14. 3rd Objective : provide new developers
Idea :
Associate : theory (the teachers)
The know how (professional developers)
The actors (students, profs, and so on)
Mentors (OpenOffice.org Project developers)
The needs (features for OpenOffice.org)
… and finally provide developers

28. Guidelines for further projects
● Be “transparent” yourself :
– Do not lie about the difficulties!
– Do not base your evaluation only on final
results.
– Take into account the methods and autonomy of
students.
● Frequent (on-line or IRL) meetings between
students and supervisors to keep up the
motivation
