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

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

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

GeoGebra = Geometry + Algebra Algebra Window Geometry & Graphics Window

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

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 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

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)

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)

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).

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)

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

Age 6-10: Adding Integers

Age 11-14: Multiplying Fractions

Age 15-18: Geometry & Algebra

Age 17 up: Functions & Calculus
