Something interest In the LOC

After I listened to the audio presentation of the library of congress, I felt it is good to know the difference between primary resources and secondary resources. As a teacher, I think it would be better to introduce students with raw materials first and provide them with the opportunities to observe, reflect, and question on the topics. Then the students will be more aware of the distinction between past and present which helps them become critical thinkers and eventually act upon the society. I remember a famous saying: there is nothing new under the sun. People are more aware of the history then are more aware of their social responsibility. As the history progresses, everyone is the part of the history. We can encourage the students to make their own contributions in the US history.
