TEACHING EXPERIENCE

I taught Chemistry and General Science in Secondary / High School for 4 years, followed by the next 3 years working as a Research Chemist. Then, I took up a Lecturer position to teach Chemistry and Applied Chemistry in a Technical Education Institution, which prepares young adults for laboratory work in the industry.

MY TEACHING STYLE

As much as possible, I would incorporate student-centered and hands-on activities in my classroom. I believe that the students are able retain knowledge better and become a more independent learner. Diagrams and flow-charts help my students to conclude a topic and relate the scientific terms in different topics.

MY OWN EDUCATIONAL HISTORY

I've graduated from the National University of Singapore (NUS) with a degree in Science (B.Sc), major in Chemistry. After which, I completed the Post-Graduate Diploma in Education (PGDE), Secondary Education, at the National Institute of Education. At the beginning of my teaching career, I pursued the Master in Science (Life Science) (M.Sc), specialization in Chemistry, at the Nanyang Technological University.

ADDITIONAL BIOGRAPHICAL INFORMATION

Besides teaching Chemistry, I had the opportunity to work on a photomicrography projects with my students and run workshops for teachers from other schools.
