Formative ______________ Assessment

Note : For detailed study material of Formative

Assessment please log on to www.cbse.nic.in

PREFACECBSE always believes in Global Trends of Educational Transformation. The CBSE curriculum

gets its lead from National Curriculum Framework – 2005 and Right to Free and Compulsory

Education Act – 2009. CBSE introduced CCE in the later half of 2009. CCE has been started to

improve the quality of Education and was meant to lessen the burden of studies on Students. CCE

stands for Continuous & Comprehensive Evaluation. The term 'Continuous' in CCE refers to

periodicity and regularity in assessment and the term 'Comprehensive' refers to overall assessment

of the learner, in both curricular & co curricular scheme of things.

These Oswaal CCE Question Banks for Classes IX & X have been written so as to supplement

the need of the students to prepare for these progressive assessments at school during the entire

year.

Oswaal CCE Question Bank has been divided into two sections: Summative Assessment (SA) &

Formative Assessment (FA). In the Summative section, chapters are arranged ‘TOPICWISE’ where

each topic is explained in detail and covers all typologies of Questions specified by CBSE, with well

labelled diagrams and high quality figures/diagrams for fast learning. Answers from CBSE

Marking scheme are highlighted in order to specify the correct method of answering questions for

attaining maximum marks.

Formative section of the book will assist the students to prepare for the frequent class room

based evaluation, both as an individual and as a group activity. The various formative techniques

include Quizzes, Chapter assignment, Work sheets, Projects, Seminar, Symposium, Action Plans,

etc. These activities have been elaborated by CBSE Board on www.cbse.nic.in. The students can

read through all these components while revising a chapter to be always prepared for the surprise

FA's in the class.

At last we would like to thank our authors, editors, reviewers and specially students who

regularly send us suggestions which helps in continuous improvement of this book and makes this

book stand in the category of “One of the Best”. Wish you all Happy Learning.

Why Topic Wise Question Banks Are A Better Choice than Previous Year’s Papers ?

Question Banks Previous Years’ Papers

1. Chapter-wise and Topic –wise presentation

in Question Banks facilitates systematic

study.

2. Question Banks can be referred to by the

students throughout the year as well as at

the completion of each chapter in school.

3. Question Banks, take into account any

changes in syllabus or layout and hence are

fully updated and aligned as per the latest

specifications by the Board.

1. Year Wise presentation restricts

methodical flow of learning.

2. These can be referred to only after the

completion of the full syllabus in school.

3. Previous Years' questions cannot be

changed and hence fail to be adept with

the latest Board specifications
