At first, I think literacy has two meanings. The first meaning is culture or civilization and the second meaning is the ability to write and read. Both meaning are very similar, they are related to cultural knowledge. But in today’s society, literacy not only means culture. The concept of information literacy is people can effectively use and recognize the information. Besides, people can redefining and evaluate themselves in today’s information society. By reading Nunberg’s Teaching Students to Swim in the Online Sea, I think the concept of literacy is the discerning ability of people. Nowadays, much knowledge is deriving from Internet. These are second hand materials, not the primary sources. Some resources are not true. The way every people think of the Web is very different. It tests their discerning abilities. Like most people judge the credibility of a website by its outward. The information literacy means to be able to effectively identify, evaluate, and use the information. Also, the information literacy is expanding to include the map, media, and some electronic text. The information literacy has a deeper meaning. Students are highly familiar about website and search engine. They are effectively integrating the concept of information literacy into their learning programs. For me, I think the information literacy is good for college students. Because it can help them recognize when the information is needed, they have the ability to use the information. Literacy information is increasingly important in college life. Students faced with diverse, rich information every day. It was a big challenge for them.
