The National Council of Educational Research and Training (NCERT) has removed periodic table, democracy, and sources of energy from Class 10 textbooks.
The Class 10 students will now no longer be able to read these concepts from their textbooks.
NCERT as per NDTV report has said complete chapters on the subjects now stand deleted as a part of a "rationalisation" meant to reduce the "burden on students".
The removal of the theory of evolution from the Class 10 curriculum stoked significant concern earlier this year.
Newly released textbooks by the NCERT have revealed further cuts, including a chapter on the periodic table, it mentioned.
“Among the topics dropped from the science textbook are also chapters on environmental sustainability and sources of energy. Full chapters on democracy, challenges to democracy and political parties have also been dropped for Class 10 students after the latest revision,” the report said.
It said the NCERT believes that it was imperative to reduce the load on students in light of the coronavirus pandemic.
"Difficulty level, overlapping content, and content irrelevant in the present context," the report mentioned the NCERT’s reasons for dropping these chapters from the curriculum.
“Students, though, can still learn about these subjects, but only if they opt for the relevant subject in Class 11 and Class 12. In India, Class 10 is the last year in which science is taught as a compulsory subject. Only students who elect to study chemistry in the final two years of education (before university) will learn about the periodic table,” it said.
Earlier this year, the NCERT had come under fire for dropping the theory of evolution from the Class 10 science textbook.
