Re: proof in geometry

Hi Maria,
I have used dynamic/interactive geometry for many years and a schema that I use in approaching proof with students from year 7 to 12 goes like this.
Experience Investigate <> Conjecture Believe Prove
The important step regarding proof is the movement from Belief to Proof and I describe "Proof" to my students as the wider communication of a personal belief.
It works.
Regards,
Jon Roberts
