SOCIAL SCIENCE
People all over the world have mobilized themselves to organize movements to restore democracy or to
strengthen the existing democratic system. The lesson ‘Popular Struggles and Movements’ tells us about
such movements and the role of Pressure Groups, Political Parties and movements. You are required to do a
project based on this. The project work will be assessed under subject enrichment activity and will be of of 5
marks
Each student will do the project on the theme as per his/her roll no.
ROLL NO THEME
1-15 Nepal witnessed an extraordinary popular movement in April 2006.
Bolivia is a poor country in Latin America where the
people organized a popular struggle to strengthen democracy.
From these two case studies you have to research on
● Why did popular movements start in both the countries and what were the main
features of these popular movements ?
● Discuss the common features as well as dissimilarities of the popular struggle in
Nepal and Bolivia. What conclusion can be drawn from the examples of Nepal
and Bolivia about democracy?
16-30 In a democracy different kinds of organization work behind any big struggle. One is
direct participation in competitive politics; other is indirect in which people can get govt.
to listen to their demands. You have to research on
● What are pressure groups or Interest Groups? Mention a few examples of the
pressure groups. How are they different from Political Parties?
● Describe the forms of relationship between pressure groups and political parties.
Give examples.
● With the help of recent examples state the differences between Sectional and
Public Interest Group.
31-47
In Nepal and Bolivia movements were launched for different reasons. As in the case of
Interest Group, the groups involved with movements also include a very wide variety.
You have to research on
● What is a movement? With the help of examples analyze how Issue specific
movement is different from Generic movement. How do they exert influence on
politics? Is their influence healthy.
