Hi! I am Dr Sazali. I am a mathematics education specialist working in SEAMEO RECSAM Penang Malaysia. I heard so much about GEOGEBRA. Hope I can learn something from here. Here we are training teachers in GeoGebra in customised courses. They come regularly from South East Asian countries and also from Africa. I had co-authored a small guide book for first time users in GeoGebra. Going to be uploaded by December 8th 2015. Hope this will help. TQ.
