National Council of Educational Research And Training (NCERT) started offering the Text Book Material Online.
NCERT is an autonomous organization of Government of India with a mission to assist and advise the governments at the Centre and in States in the Education Policy Implementation.
NCERT’s Online Textbooks initiative will help students and teachers where teachers can adopt a more modular approach, rather than a sequential approach to teaching and learning, through access to a variety of teaching and reference material.
All these NCERT Online Textbooks are based on National Curriculum Framework 2005.
