FEATURES:

The National Curriculum Framework (NCF) – 2005 initiated a new phase

of development of syllabi and textbooks for all stages of school education.

Conscious effort has been made to discourage rote learning and to diffuse

sharp boundaries between different subject areas. This is well in tune

with NPE –1986 and Learning without Burden 1993 that recommend

child-centred system of education. The textbooks for Classes VI, VII and

VIII were released respectively in 2006, 2007 and 2008. Overall the books

have been well-received by students and teachers.

The NCF – 2005 notes that treating the prescribed textbooks as the

sole basis of examination is one of the key reasons why other resources

and sites of learning are ignored. It further reiterates that the methods

used for teaching and evaluation will also determine how effective these

textbooks prove in making children’s life at school a happy experience,

rather than a source of stress or boredom.

The NCF further recommends that evaluation has to be integrated

with the learning process and the routine activities and exercises

going on in the classroom can be employed effectively to assess learning.

This is so as the purpose of assessment is necessarily to improve the

teaching-learning process and be able to gauge the extent to which

capacity of learners have been developed.

With regard to development of questions for evaluation of students,

NCF – 2005 has made specific recommendations. It emphasises that the

types of questions which are set for evaluation, need to be beyond the

textbook questions. Questions that are open ended and challenging

should be used and they should test reasoning and creative abilities rather

than memorisation of facts and figures. The question in constructivist

evaluation should be framed in such a way that they do not seem to be

an exercise that the teacher wants children to do.

In order to address such issues, the Department of Education in

Science and Mathematics (DESM) has made an attempt to provide this

additional learning material at the upper primary stage. This resource

book contains different types of questions of varying difficulty level.
