Overview
Introduction to GeoGebra
NCETM project
Theoretical framework
Examples from teachers
User Community
GeoGebra
GeoGebra is Open Source Available
in schools and at home Online collaboration
International communityUser forum – users help usersGeoGebraWiki – pool of shared materials
Expandableby using other open source libraries

Aims of NCETM project Establish a group of GeoGebra experts who can
lead activities in England Build a network of teachers/professional
developers in England Create support network for teachers Find out together how to run professional
development activities Develop materials together that are aligned with
the English curriculum Write papers and present in conferences
GeoGebra
NCETM project Participants
Teachers with GeoGebra knowledge 9 (instead of 4) teachers from different part of
England
Work on different levels and topics of GeoGebra Collaborative activities and sharing with the
community (local Wiki) To offer support and professional development
for teachers in England
GeoGebra
NCETM project Workshops
Sheffield, Cambridge, London, Comberton… Interests for collaboration
Local workshopsOrganising local workshops and activities
GeoGebra
NCETM project Data collection
Collecting a pool of GeoGebra materials from participant teachers
Videotape meetings and workshops Interview participants Workshop feedback questionnaire
Analysis/Outcome Identify topics/levels in the English curriculum Incorporate ideas from teachers into development
(PD and software)
GeoGebra
NCETM project
Theoretical framework Utilising experiences from the LCM and
ICTML projects in Norway by Barbara Jaworski and Anne Berit Fuglestad
Utilising communities of practice research and activity theory
Tight collaboration of teachers and researchers (didacticians)
GeoGebra
NCETM projectA learning community is group of people who
(express the intention to) work together on common areas of interest and with respect to common goals -- and learn through the collaborative process.
In a learning community, “learning involves transformation of participation in collaborative endeavour”
(Rogoff, Matusov & White 1996, p. 388).

NCETM project Encourage teachers to
work togetherwork with didacticiansengage in research activitiesevaluate their own work think about curriculum designpublish their workdevelop networks (locally)
