Understand ideas and concepts is important. It is more important for students to understand ideas and concepts than it is for them to learn facts. Learning ideas means students understand the rationale based in the subjects so he or she can study and research by themselves. This is crucial in advanced stage for most advanced classes require its alumni to figure out why questions such as why this is important or why this happens. In addition, we live in the information society. Most up to date knowledge are codified and uploaded on the web. In the past, the time people couldn’t search information in short time, good memories might be a key for success, now we can find most information by just typing and clicking. As a result, knowing facts itself doesn’t mean success anymore. Imagine you’re learning human body organs. Memorizing its names and functions will be challenging but if you take enough time you will accomplish it one day. But this sort of knowledge evaporates in no time since quantity of information to remember is too much. On the other hand, let us assume that you start studying body organs from clarifying big concepts such as organs for digestion or breathing. You can forget or be confused with single body part, but, it’s hard to forget human needs to breathe. If you can’t remember the name or its function, you can just search “organs for breathing” on the web and not in a long time you can find what you want.
