GeoGebra Ambassador #7

Who are you, what are you doing?

I am Anthony C.M. Or from Hong Kong. I was a secondary mathematics teacher for many years and is now a curriculum development officer in the Education Bureau. My major duty is to develop some learning and teaching resources in Mathematics to cater for the learning needs of students at primary and junior secondary levels. I also conduct studies with focuses on how to improve learning and teaching of mathematics, and organize seminars and workshops for teachers.

When did you first try GeoGebra?

I first tried GeoGebra 3.0 in 2008 and found it a wonderful dynamic geometry software. Since then, I use GeoGebra a lot to develop learning and teaching materials.

What do you hate in GeoGebra?

I have nothing to hate in GeoGebra. I would love it more if its functions of text formatting can be further enhanced.

What do you love in GeoGebra?

I love its dual (Graphic and Algebraic) modes of representations and constructions. I love its powerful commands, scripting and the conditional showing of objects. I love the flexibility it provides such as the customizable toolbar and Java-based HTML output. I love its nice Graphical User Interface. I love GeoGebraTube. Finally, I love the freeness of GeoGebra, not only in terms of price but also in terms of the liberty to implement my ideas freely.

What are the GeoGebra related activities you participate?

I am a co-chair of GeoGebra Institute of Hong Kong. We organize GeoGebra workshops for teachers. We also develop websites to foster the use and sharing of GeoGebra materials suitable for Hong Kong curricular.
