In the past, a majority of academics have held the opinion that universities should only offer a theoretically-based approach to teaching throughout their courses, as opposed to the more recent trend towards empirical acquisition of knowledge involving more “hands on” experience. In my opinion, however, theoretical knowledge is necessary. And one will definitely benefit from it.
First, fundamental theories, such as math and physics, are the basis of other knowledge.To a student who majors in automatic control, the course of control system is the most practical and useful in the future. But if he isn’t good at math and circuit, he will hardly be able to understand the principles and methods of how to control a subject or process. It is just like constructing a building. How can you imagine a spectacular high-rise without a firm ground sill? That is, theories and practices are interrelated. We can ignore neither of them.
Second, theoretical basic knowledge provides not only the knowledge itself, but also a way that how to learn and research. University is a place for scientific research and invention. So itis necessary for students to have the skill of doing research. Seeing from another angle, science and techniques are exploding so quickly that present skills will soon be out of date. If one learnt nothing except practical skills, he would also fall behind the society. But if one could master the method of research, he would be able to refresh himself continuously with advanced technology.
From all the commentaries above, we can learn the important role of theoretical knowledge.Although pragmatism is very popular today, we should pay enough attention to the basis and principles.
