What do I learn from the sociology class?

There are many things I have learned in the sociology class; from social primary group to social stratification, from theoretical perspectives to racial and ethnic diversity in the community. All those things I learned in the sociology class come from three major fields:
(1) Learning from the (text) book
(2) Learning from the instructor
(3) Learning from the class (presentation, research paper, etc)

(1) Learning from the (text) book
The book, ‘Society: the basics’ by John J. Macionis is remarkable and impressive. As a non-native English speaker, language is still barrier in studying. Even though it is not very easy to read this book, it is not very difficult, either. The clear writing style helps me to highly comprehend.
There are many interesting categories in every single chapter of the book. From sociological theories, perspectives, approaches to scientific sociology are also studied in the book. Let me pick a couple sentences that make me impressed up here;
“These tropical forests are vital to maintaining the Earth’s atmosphere. Deforestation ends up threatening everyone, including those people back in the United States enjoying their hamburgers.”
This means tons. When I told this to my wife, she said that ‘let’s don’t eat hamburgers in future.’

(2) Learning from the instructor
There are several things that we also have learned from our wonderful professor, Sherwood Edwards. He usually speaks clearly and firmly with fluent English and appropriate examples. Here are a few notes from his lectures;
When we study about the bureaucracy, I learned from his sociological perspective that ‘We cannot manage organization without bureaucratic leadership; in other words, we cannot move bureaucracy from the society.’
Impressively, another idea that he give me is- ‘Smart people always dominate doom people.’ ‘All men are born equal, but after that, quality become differential, based upon time, circumstance, condition and opportunity that individuals are coordinate.’

(3) Learning from the class
The research paper gives me opportunity to understand that ‘how to use the SPSS system, how to read the statistics and to see both of micro and macro views of today’s society.
The class presentation also gives us to know and understand more each other among the classmates.

Briefly, I feel that I get a ‘sociological glasses’ from this class to see society by the sociological view.
