We are in the midst of a Data Revolution

• BigData, open source data, structured and unstructured data, geospatial data, …

• It challenges us to rethink data, information and knowledge

• But will big data offer answers to the big questions?

• Data doesn’t just reflect the world, but also changes it

Sudden infant death syndrome (SIDS or cot death) in New Zealand

• In the 1980s, one in every 250 babies died suddenly, unexpectedly and without explanation (≈240 babies per year, in today’s terms)

• Indescribable trauma – many theories, no solutions

Sudden infant death syndrome (SIDS or cot death) in New Zealand• New Zealand Cot Death Study

• 3-year case-control study (1987-1990)

• Multidisciplinary – social determinants of health framework

• Three modifiable risk factors identified, published in 1991 –prevention campaign launched:• prone sleeping position

• maternal smoking

• lack of breastfeeding

Sudden infant death syndrome (SIDS or cot death) in New Zealand

• prone sleeping position (≈43% to less than 3%)

• maternal smoking (≈34% to ≈10%)

• breastfeeding to 6 weeks (≈85%)

• Over 3,000 New Zealand babies lives saved by 2008

• 25 SIDS death in New Zealand in 2015

• UK fell from 1,500 to 600 per year by the mid 1990s

BigData

• Today’s world is increasingly digitised; the amount of data produced daily is truly mind-boggling. In 2018 it was estimated that 2.5 quintillion bytes of data created each day, and this is rapidly accelerating

2,500,000,000,000,000,000

• In the last two years alone, 90% of the world’s data were generated

• New Zealand’s Integrated Data Infrastructure (IDI) holds microdata about all New Zealand people and households; it individually links detailed data from health, education, justice, income and work, population, and many other sources

• Conceptually appealing to bring together data from multiple sources

• Will big data offer answers to the big questions?

• Conceptually appealing to bring together data from multiple sources

• Will big data offer answers to the big questions?

• What we can learn about educational success when multi-disciplinary data are weaved together from a social-determinants framework

• E.g.: Pacific Islands Families (PIF) Study

• But what about the translation to practice

• Stakeholder perceptions of data sharing

• Ethics, Law, Privacy, Consent, Big Brother (surveillance)

• Implementation

Research Motivation

• What does `educational success’ mean?

• Pacific perspective vs. Documented outcome

• Integrated membership within NZ society

• Success in both Pacific and Palagi worlds

• Cultural identity and competence

• English language mastery essential for scholastic achievement in the English-medium schools

Phase 3

Phase 2b - Focus Groups

Phase 2a - Questionnaires

Phase 1

Who? Year 0-2 Teachers (n = 7; 78%)

Where? Three Canterbury Schools Decile 1, 6 and 9

How? Questionnaire – Quantitative (n = 26)Focus Groups – Qualitative (n = 7)

Thematic Analysis Focus Groups

Theme 1: The Roles are Changing

• The role of the teacher, the school and the parent are changing

• Needs of the community are changing

• A more holistic focus • Need for more integrative approaches

Thematic Analysis Focus Groups

Theme 2: Holistic Benefits

• For both students and their whanau

• Timely, appropriate, consistent support• Support from day one (or even before!)

• Academic achievement

Thematic AnalysisFocus Groups

Theme 3: Risks

• Misuse of information

• Judgement/ stigma/ disadvantaging students

• Negative experiences with schools and other agencies

• Scared of agency intervention

Thematic AnalysisFocus Groups

Theme 4: Solution-Focused Implementation

• Partnership: Building relationships and trust• Building meaningful, trusting relationships

• Participation: inclusion of parents in how data is used• Including whānau communication, decision-making

• Protection: always having the child’s and whānau’sbest interests

Implications Where to next?

• Ask parents

• “Principles of data sharing” What is the current legislation?

Is the current legislation working for us?

Where could current legislation be improved?
