A biology lecturer says a video on creationism shown to students is a piece of propaganda.

It comes after former students at an Auckland private school say creationism was taught as a preferred theory of how everything began.

They say a video on the subject was shown to a class of students without any discussion or context.

Waikato University lecturer in biology Dr Alison Campbell told Kate Hawkesby it could be used for debate but not as proven truth.

"It's unfortunate if students are presented non-science, I guess, or a biased science view. I think science and technology in our world today, are too important for us to give students the disservice or a poor education in the subject."
