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

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).
