My study examines the scientific reasoning abilities of school children from Singapore who have just completed their primary education.  A paper-and-pencil test – the Primary Scientific Reasoning Test (PSRT) is constructed to measure their scientific reasoning abilities. I am investigating the construct validity of the PSRT by considering the extent to which explanatory concepts from emerging scientific reasoning research accounts for the children’s test performance. This study addresses the need to develop valid and reliable instruments for testing scientific reasoning skills.

I was a secondary school science teacher for ten years prior to joining the Singapore Examinations and Assessment Board. During my teaching career, I was involved in a number of award-winning research projects which required conceptualisation, design and evaluation of appropriate assessment instruments. One such project, which had the support of the Ministry of Education, was a three-year Student Action Research (STARS) programme. In STARS, participating students apply the process of Plan-Act-Observe-Reflect to investigate classroom, school or community linked issues. Findings from the STARS research were published and disseminated to all Singapore schools as well as presented at various sharing platforms.

In 2008, I received the country’s highest honour for educators – President’s Award for Teachers. A year later, I joined SEAB where I was in charge of national examinations of science subjects at various grade levels. In 2012, I received my Master of Education (Educational and Psychological Measurement and Evaluation) degree from Nanyang Technological University in Singapore. For the degree, I was awarded the certificate of commendation for the 2012 Singapore Teacher’s Union Gold Medal as one of the top three graduates of the course.

I am currently into my fourth year of study. I target to submit my thesis in July 2018 for examination (viva voce) two months later. I have just successfully completed my Confirmation of Status Examination in September 2017. My supervisors are Professor Jo-Anne Baird and Dr Joshua McGrane. I am advised by Professor David Andrich and Dr Jane McNicholl.
