Biography
Lorraine’s teaching experience spans many decades in schools and university. She is a former Editor of Australian Primary Mathematics Classroom, a former President and Life Member of The Mathematical Association of Western Australia, a Life Member of the Australian College of Educators, member of the Mathematics Education Research Group of Australasia and past member of the National Council of the Australian Association of Mathematics Teachers. Lorraine has been a member of the Reframing Mathematical Futures II research team, and as part of this team was a recipient of the 2018 Beth Southwell Practical Implications Award. In 2018 she was awarded an Australian Award for University Teaching Citation and a Vice Chancellor’s Award for An Outstanding Contribution for Student Learning.
Lorraine’s passions are engaging students in mathematics learning and supporting the important work of teachers. She is a regular contributor to mathematics education journals and has presented at state, national and international conferences. She has written two books to assist teachers and enjoys working with schools in their professional learning programs.

Teaching areas
Lorraine’s teaching expertise is in the area of primary and middle years’ mathematics education. Her particular focus is on using engaging pedagogies to allow teachers to create working mathematically classrooms where students are able to make sense of the mathematics they are being taught. She does this by developing mathematical content and pedagogy together, using a ConcreteRepresentationalAbstract learning framework, to increase her students’ mathematical pedagogical content knowledge and mathematical knowledge for teaching.
Undergraduate courses taught
 EDUC1635 Mathematics 1: Introduction to Mathematics Teaching
 EDUC2652 Mathematics 2: Number and Algebra
 EDUC3636 Diagnostic Mathematics Clinic
 EDUC4639 Mathematics 4: Statistics and Probability
 EDUC4321 Research and Scholarship: Mathematics

Research expertise and supervision
Lorraine’s research interests are in improving the effectiveness of teachers of mathematics. She is particularly interested in mathematics education research that directly affects teachers in classrooms. Over the last seven years, she has been working on developing evidencebased learning progressions and the associated teaching advice to assist teachers to identify where their students are and how to move them forward in their learning journeys. Two particular areas of research interest and expertise are algebraic reasoning and multiplicative thinking.
