For instance, where domestic plumbing and electricity, car maintenance and carpentry are concerned, most people have become accustomed to meeting their needs by spending money. But over time this leads to the wasteful habit of throwing things away as soon as they break down, and causes our science education to remain at the stage of the written word and spoon-fed concepts. There is little in the way of understanding gained through practical experience.
舉例來說，居家水電、汽車修護、或木工，一般人多半習慣以金錢解決，但久而久之卻造成用壞即丟、大量浪費生活資源的現象，也使我們的科學教育停留在文字與概念灌輸，沒有實際體驗。
