MERGA 42 — 42nd Mathematics Education Research Group of Australasia (MERGA) Conference 2019

Welcome to Perth for MERGA 42 for what should be a memorable conference. We are delighted to be hosting this conference as it is 25 years since it was last held in Perth and nine years since it was last hosted in Western Australia. The Mathematics Education Research Group of Australasia provides an inclusive and cosmopolitan Conference. We look forward to seeing mathematics educators - and academics involved in mathematics education - from many countries.
