MPs have been told principals with no technological savvy are holding back their schools and their students.
Tawa Intermediate's principal Carolyn Stuart told Parliament's Education and Science select committee on Wednesday there is a digital divide between schools led by principals who make great use of technology and those that are not.
The select committee is investigating 21st century learning environments.
Ms Stuart told the committee that principals excel at running their schools, but most need help connecting technology with teaching.
She says schools that do not embrace new technologies are forcing children to dumb down.
Children from Ms Stuart's school made their own submission to the committee.
They called for one computer for every child over the age of 10, more training for teachers, and classrooms designed for children to work together rather than sit still at their desks.
