上課鐘聲響起，學生拎著書包趕往教室上課。教室裡的時鍾滴答轉，伴隨鐘聲提醒著我們一堂課的開始與結束。但你知道嗎? 這不是學習唯一的方式! 如今開放式課程興起，改變我們對學習的想像。
臺大 NTU Courses 頻道與開放式課程網站 (OCW)，希望促進教學資源共享與終身學習。不管你是在等車、在吃飯、在用功，不管你是想自修、想複習、想放鬆，你都可以為自己選一堂好課，讓臺大老師精彩的教學隨時在你耳邊響起!

Learning usually seems to be confined to a certain space and time, but this is not the only way to learn. So far, the OpenCourseWare movement has broken the limitation of time and space, changing our imagination on learning.
Now via the Internet you are able to listen to a course anytime, anywhere, just by yourself!
