The phrase "Education 3.0" is used to signal a complex and still-evolving paradigm shift from the traditional schooling models of the 19th and 20th centuries (Education 1.0), via an intensified focus on teachers' and school leaders' accountabilities in relation to students' learning (Education 2.0), towards a more holistic model of education that is appropriate to the 21st century. This report scopes possible Education 3.0 metrics that Te Aho o Te Kura Pounamu--The Correspondence School of New Zealand--might consider using to document the learning of students and associated practices used by teachers to support that learning. This report has been developed to support strategic decision making by the Te Kura leaders and board of trustees. Although this work is essentially forging new ground in the New Zealand context, there is useful prior work that can inform the approach Te Kura decides to adopt. This report distils key messages from existing research of relevance to the identification and selection of areas on which to focus and to the metrics that could be used. These insights are brought together with key findings from workshops with two groups of Te Kura teachers to scope challenges and key areas for decision making.
