Teachers should be filmed in the classroom so they can review and improve their performance, a member of the expert Gonski panel says.

Kathryn Greiner, who conducted a major review of school funding alongside business leader David Gonski, said teachers could gain a fresh perspective on sharpening their skills by watching themselves on video.

"I have to say it is about time teachers understood that they must be assessed, they must be a part of professional development and I would like to see every single teacher in every single classroom in Australia videotaped," she told a Mitchell Institute education forum.

Ms Greiner later told The Age that teachers could view the video footage together with a colleague or mentor. "The best way of learning is to see yourself and have somebody help you."
