The changes also involved a re-working of the teaching role and the craft of teaching at Hadlow School, which was the first in Wellington to modify existing facilities to create an MLE.
"No longer would a class of children be doing the same work at the same time. The key instructional areas of the curriculum - reading, writing, and maths - would still be delivered in small-group or individual way, but learners could determine the order of the activities they had to complete each day and week," Mr Mercer said.
"The other major change would be the end of the single-cell model of one teacher with one class operating behind closed doors. Teaching would become collaborative with groups of teachers in a larger, open space, tapping in to each person's particular strengths and sharing responsibility for all the children."
The MLE comprises integrated, multi-purpose, variable spaces, he said, and inter-connected buildings with large spaces easily divisible into learning commons and break-out rooms. Integral to the hubs was a wireless information and communication technology system as well.
Hadlow School teachers and senior managers visited Auckland schools to view future-focused education, he said, and also visited Amesbury School in Wellington, which was the first new school in the capital city region to be built "in the modern style".
Hadlow and Amesbury schools had developed "a strong professional relationship", Mr Mercer said, and intensive development was undertaken with world-renowned educational expert, Mark Treadwell.
Hadlow teachers for the past three years had been trialling collaborative learning models, and this year the whole school became hub-based, Mr Mercer said.
The school also had hosted numerous groups of principals and teachers from Wairarapa, Hawke's Bay, Manawatu, Horowhenua and Kapiti Coast over the last two years, Mr Mercer said, as schools in those regions develop future-focused teaching and learning.
