The year1 teacher at Kellyville Public School spoke to the News on Friday, World Teachers Day.

She said she was driven by the looks on the faces of her pupils when they learnt something new.

``Seeing their faces light up, when they say `I get it!' is amazing,'' she said.

``It's incredible to think I did that, to teach them something they didn't know. It's adding something new to their lives and is life-changing that moment, that expression, is fantastic!''

Mrs Kimble, 26, studied for a degree in human communication in Cardiff, Wales, before volunteering at a special-needs school.

She enjoyed her time there so much she enrolled for a postgraduate degree after moving to Sydney in 2005.

She said a good teacher was patient, empathetic, respectful and approachable and, most importantly, motivating, inspiring and consistent.

``If the kids are going to lunch having an animated conversation about what they've just learnt, or bringing in extra research, or drawing a picture about a book you read yesterday, it's a big tick,'' she said.

Mrs Kimble reviews what worked and what did not at the end of each lesson and shares her ideas and resources with colleagues.

``Everyone has lessons that don't work well but having people on your team to help you makes such a difference,'' she said.

``It's like creating a tapestry or sounding board that you work off.

``We have to be open to new ways of learning and the advent of technology.

``Most of the jobs my students will have jobs that don't exist yet.''
