Sociology Holiday Homework:

Class : XI

Welcome to Sociology! Firstly, given that you are new to the subject, Sociology

studies everyday life. Sociologists aim to raise questions about social life and our

world today – about how people live and why people live as they do and issues



about how we live. Sociology is concerned with peoples, groups, cultures,

societies and their patterns, variations and problems. It aims to understand and

explain human actions. It employs a wide range of interesting research methods

such as interviews, questionnaires and observations to investigate and answer

crucial questions about society and social life. It tries to link past, present and

future.

1) Do some research!! Investigate: talk to someone of a different generation

– parents or grandparents or both – about how they feel the family has

changed – how were things different in the past to what things are like

now? Why do they think these changes have happened? What are the

positive and the negative effects of these changes? What do they think

might happen to the family in the future?

2) Do exactly the same for education system.

3) Do a Print Media Search: Look at some newspapers and find out what they

report about family and Education system. Cut out some examples. Are the

reports positive or negative or neutral? What viewpoint is the writer

taking?

4) Use the internet; answer these questions to understand some key terms in

sociology: What is Socialisation? What are the two types of socialisation?

What are norms, values, roles?

5) Gender Roles: Think!! How do boys become boys and girls become girls?

Think about your own family experiences and those of your friends. What

toys did you play with? What toys do you consider ‘boys’ and ‘girls’ toys?

What kind of games do boys and girls play? How are they similar or

different? Does childhood and play prepare boys and girls for different

roles in adult life? What expectations are there of boys and girls in your



experience? Think about the language that is used when parents talk to

boys and girls is it different? How? What role does socialisation play in the

formation of gender roles?
