, Foreword
THE National Curriculum Framework (NCF), 2005, recommends that
children’s life at school must be linked to their life outside the school.
This principle marks a departure from the legacy of bookish learning
which continues to shape our system and causes a gap between the
school, home and community. The syllabi and textbooks developed
on the basis of NCF signify an attempt to implement this basic idea.
They also attempt to discourage rote learning and the maintenance
of sharp boundaries between different subject areas. We hope these
measures will take us significantly further in the direction of a child-
centred system of education outlined in the National Policy of
Education (1986).
The success of this effort depends on the steps that school
principals and teachers will take to encourage children to reflect on
their own learning and to pursue imaginative activities and
questions. We must recognise that, given space, time and freedom,
children generate new knowledge by engaging with the information
passed on to them by adults. Treating the prescribed textbook as the
sole basis of examination is one of the key reasons why other resources
and sites of learning are ignored. Inculcating creativity and initiative
is possible if we perceive and treat children as participants in
learning, not as receivers of a fixed body of knowledge.
These aims imply considerable change in school routines and
mode of functioning. Flexibility in the daily time-table is as necessary
as rigour in implementing the annual calendar so that the required
number of teaching days are actually devoted to teaching. The
methods used for teaching and evaluation will also determine how
effective this textbook proves for making children’s life at school a
happy experience, rather than a source of stress or boredom. Syllabus
designers have tried to address the problem of curricular burden by
restructuring and reorienting knowledge at different stages with
greater consideration for child psychology and the time available
for teaching. The textbook attempts to enhance this endeavour by
giving higher priority and space to opportunities for contemplation
and wondering, discussion in small groups, and activities requiring
hands-on experience.
The National Council of Educational Research and Training
(NCERT) appreciates the hard work done by the textbook development
committee responsible for this book. We wish to thank the
Chairperson of the advisory group in Social Sciences, at the higher
secondary level, Professor Hari Vasudevan and the Chief Advisor for
this book, Professor Tapas Majumdar, for guiding the work of this
2019-20
, committee. Several teachers contributed to the development of this textbook; we are
grateful to their principals for making this possible. We are indebted to the
institutions and organisations which have generously permitted us to draw upon
their resources, materials and personnel. We are especially grateful to the members
of the National Monitoring Committee, appointed by the Department of Secondary
and Higher Education, Ministry of Human Resource Development, under the
Chairpersonship of Professor Mrinal Miri and Professor G.P. Deshpande for their
valuable time and contribution. As an organisation committed to systemic reform
and continuous improvement in the quality of its products, NCERT welcomes
comments and suggestions which will enable us to undertake further revision and
refinements.
