My PhD required the writing of a dissertation. It involved Educational Psychology, which I was specialising in, combined with the learning and teaching of a topic in secondary school Chemistry. The study contributed to our theoretical understanding of learning and teaching and at the same time had implications for the enhancement of the teaching and learning in the Chemistry classroom. Hence the title of the dissertation, which was:
Mental representation of knowledge for a topic in high school Chemistry
The research for the dissertation was done in Hong Kong after the course-work requirements had been completed at Stanford. The subjects for the research came from a Form 4 Chemistry class at a local secondary school in Shatin, Hong Kong. The study included both qualitative and quantitative research methodology.
Pre-dissertation course paper
When seeking out possible areas of research for my dissertation, I wrote a paper in a course dealing with mental models that people have, especially in the domain of Science. The paper included a mental model that Leonie, then 5 years of age, might have had of the internal parts of the human body. The picture on the right shows a drawing by Leonie (of my course teacher!) - refer to the course paper for details. Also, you can click on the picture at the right to get an enlarged view.

Ph.D. dissertation
The published dissertation is well over 500 pages in length, which necessitated two volumes! I have included links to view the dissertation but it may not open or may take a long time. It may also depend on the browser you use. However, a detailed abstract of the dissertation is available, which gives a very good description of what was involved. To view the abstract, click on the following link:
