  1. GeoGebra Establishing a professional development network with an open-source dynamic mathematics software – GeoGebra Zsolt Lavicza and Markus Hohenwarter University of Cambridge, Florida State UniversityNCETM conference, December 2008 www.geogebra.org , www.geogebra.org/IGI

  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 • 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 • 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. Teacher demonstration Pupils create their own files Pupils interact with teacher created files Linking Text text

  18. Examples from teachers: Teacher demonstrations

  19. Examples from teachers: pupils interact with files

  20. Examples from teachers: students recreate constructions

  21. World Wide User Community 42 languages 190 countries 500,000 visitors per month

  22. Visitors on www.geogebra.org

  23. GeoGebra User Forum www.geogebra.org/forum

  24. GeoGebraWiki – Free Materials www.geogebra.org/wiki

  25. International GeoGebra Institutes • Teacher training and support • Offer (free) workshops • Material and software development • Share (free) materials and develop software • Research • Encourage and coordinate collaborative research • Current Local Institutes • Norway, Austria, Poland, Spain, Denmark, Hungary • Soon opening • Italy, Sweden, Slovakia, Portugal, Philippines, California, Florida, Illinois

  26. What's next? • Spreadsheet • Statistical features • Computer Algebra extension • GeoGebra 3D • Interactive Whiteboard features • Keep GeoGebra simple and easy to use • Research on local user communities

  27. Workshops • Participants are eager to offer workshops in England • If you are interested in organising one please let us know (zl221@cam.ac.uk)
