In 2014, I completed my PhD in Mathematics Education. My PhD looked at Primary School Students' understanding of whole number place value. My research involved designing and validating an assessment tool for place value. It was called the Place Value Assessment Tool (PVAT). I also trialled an online version of the test called the PVAT-O (online). Almost 1000 students completed the PVAT and PVAT-O. From this data, I determined six key areas of place value content that students must be familiar with and identified four stages of knowledge required to master the construct.
Through sharing my knowledge, I am very keen to help improve the teaching and learning of place value across the world. As such, I have developed the App "Zero Our Hero". This App is based on my research findings and is a wonderful resource for teachers, parents and students.
