It is more important for students to understand ideas and concepts than to learn facts Which is more important, understanding ideas and concepts or learning facts, is always a controversial issue among people. From my perspective, they both enact a irreplaceable role in study.There are several reasons below. To begin with, only learning from books, we can not know about how and why we should learn the knowledge what have been taught. For instance, on campus in China, it is common to find that there is a teaching pattern called test-oriented education, which emphasize theories what can enable students to attain a good mark in the examination. The results of this mode of teaching, obviously, make students neglect the essence meaning of learning knowledge - they just study for study's own sake. Take basic science course for example, the ideas and concepts of its content can help students comprehend the common phenomenon in daily life, such as the formation of rainbow, the reason of rain. However, without combination of concepts and facts, this knowledge what students have learned in class is just some words in books and the content of examinations. Additionally, only concentrating on the facts, students may confuse what lead to them occur. why are we supposed to study in a school? It just because nothing but we can not understand something by ourselves, so the key of comprehension is to learn some theories imparted by teachers. The methods and knowledge which are taught in school are proven concepts with many universal characters of facts. It is mature and easily understanding. It is clear that everyone knows that people can use a computer for search, but why people can do it, without leaning relevant concepts of computer science, no one can answer. Lastly, when both understanding ideas and concepts and learning facts, it is more likely it possible for students to have a grasp of what have been taught. Just as a saying goes, "Practice is the sole criterion for truth.", it is also true of students. When learning the concepts in class, even if teachers talk to us all of them are true, without any testings by ourselves, we are not supposed to give up to think critically. In retrospect the celebrities like Darwin, even though there were some explanation of the evolution of organisms, he still devoted himself to find the truth, and finally have found it through facts of nature but what Darwin has discovered could not separate from the concepts what have ever existed
