From his years of experience teaching natural science, Lai discovered that through allowing students to observe living things at first hand, his work was cut in half. Students not only learn faster in this way, but they remember more as well. They also have more interest in reading and conducting research.
他由教自然科的經驗中發現，讓學生從實物觀察中學習可以事半功倍，不僅學得快，而且記得深，更能培養出讀書的興趣和研究的精神。
