City University president Way Kuo came from a science background, but has a keen interest in educational work. When he was in the United States, he spent a lot of time on educational research despite his busy school administrative duties.
Professor Kuo recently published Clarifying Some Myths of Teaching and Research (Clusty), which he jointly penned with education psychologist Mark E Troy, detailing the results of a study on 10,000 students and 400 teachers.
The study explores the relationship between research work and quality of teaching, and explodes – or confirms – certain myths within education circles, as the book title suggests.
Kuo was invited by the Hong Kong University Graduates Association to give a speech on his new book, and many interesting education- related issues were raised during the talk.
One of the questions concerned whether scholars who engage in research work perform worse in teaching, and whether class size affects teaching performance.
