Nick Howe, the Area9 Chief Learning Officer, is joined by Henrik Harder who was the CEO of the Danish roadwork education centre VEJ-EU in late 2018 when the project we discuss was undertaken. They describe shifting a full day of face to face theory training with a very diverse audience to an adaptive, personalised online platform. One outcome was that the time to complete the knowledge component of the course reduced from 8 hours to a median of less than 3 without removing any content and allowing even the slowest of learners to achieve proficiency.
