Progress on thesis

My study examined the scientific reasoning abilities of school children from Singapore who had just completed their primary education.  I target to submit my final thesis in September 2018 for examination (viva voce). My supervisors are Professor Jo-Anne Baird and Associate Professor Joshua McGrane. Professor David Andrich is my advisor.

Professional and educational background

I started my DPhil at OUCEA supported by a scholarship from the Singapore Examinations and Assessment Board (SEAB). I was a secondary school science teacher before I joined SEAB. During my teaching career, I participated in some 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 this degree, I received the certificate of commendation for the 2012 Singapore Teacher’s Union Gold Medal as one of the top three graduates of the course.

Achievements this year

My academic portfolio included conferences, seminar presentations, poster sessions, publications, abstract and manuscript reviews, as well as outreach efforts. A notable achievement this year was the recent completion of a chapter for a book edited by Professor Sibel Erduran of Oxford University to be published by the Royal Society of Chemistry. The chapter focused on an emerging and important aspect of science learning – the assessment of scientific argumentation.

I also participated in two note-worthy cross-cultural and cross-institutional projects to engage with emerging assessment and science matters. These were a piece of collaborative research between Educational Testing Services and Oxford University Centre for Educational Assessment on rater scoring in essays, and a Wellcome Trust-funded project on enhancing the summative assessment of practical science in England. In March this year, I accepted an invitation to review manuscripts for EURASIA Journal of Mathematics, Science and Technology Education. As a reviewer of this journal, I have an opportunity to keep abreast with developments in another emerging field – STEM education. The latter half of the year will be devoted to the completion of my thesis and the final preparation for the viva.
