GeoGebra use in mathematics teaching.
We have learnt the very basics of GeoGebra use to construct and dynamically present the very basics of geometry: lines, angles, triangles, circles, quadrilaterals, ...
Our workshop guided participants through the first steps of incredible potential which GeoGebra provides for successeful teaching.
As a motivation two samples of potentially useful GeoGebra applets were provided :

Many more can be explored via GeoGebra Book. Especially interesting for the GeoGebra workshop participants might be those in the chapter 'Elementary Geometry'. Many of the applets are quite sophisticated. Some are elementary and can serve as a challenge also for those, who want to learn GeoGebra from scratch.

Some of the unfinished applets we worked on and discussed on the March 1 workshop can be dowloaded from 'compressed'.

Workshop was conducted by

D. Kobal has been teaching Didactics of Mathematics at the Faculty of Mathematics and Physics of the University of Ljubljana for many years. He has been in charge of national in-service training for mathematics teachers, conducting numerous workshops and lectures for pupils, students and teachers both within Slovenia and abroad. He is critical and dedicated teacher, reluctant to talk about 'old' and 'new' methods, but advocates recognition of good teaching, whether it is based on classical 'knowledge and teaching charisma', or if inspired by constructive use of modern technology. Among his many teacher's references it is probably worth mentioning his plenary lecture at the First International GeoGebra Conference in Hagenberg, Austria in 2009, participation at the International Seminar on Mathematics Education organized by PCMI - IAS (Park City Mathematics Institute - Institute for Advanced Study in 2011 and 2013), and his active participations at the International Congresses of Mathematical Education ICME-11 in 2008 in Mexico, ICME-12 in 2012 in Korea and ICME-13 in 2016 in Germany.
