2. Overview Introduction to GeoGebra NCETM project Theoretical framework
Examples from teachers
User Community

3. GeoGebra is Open Source
Available in schools and at home
Online collaboration
International community
User forum – users help users
GeoGebraWiki – pool of shared materials
Expandable by using other open source libraries

4. GeoGebra = Geometry + Algebra Algebra Window
Geometry & Graphics Window

5. 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

6. 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

7. NCETM project Workshops Interests for collaboration Local workshops
Sheffield, Cambridge, London, Comberton…
Interests for collaboration
NRich project
Further Mathematics Network (on-line course)
Local workshops
Organising local workshops and activities

8. NCETM project Data collection Analysis/Outcome
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)

9. 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)

10. NCETM project
A 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).

11. NCETM project Encourage teachers to work together
work with didacticians
engage in research activities
evaluate their own work
think about curriculum design
publish their work
develop networks (locally)

12. Different age levels Developing teaching materials for various levels
Examining the curriculum for the suitability of GeoGebra
Developing workshop materials for professional development

13. Age 6-10: Adding Integers

14. Age 11-14: Multiplying Fractions

15. Age 15-18: Geometry & Algebra

16. Age 17 up: Functions & Calculus

17. Linking Teacher demonstration
