In accordance with the National Education Policy (NEP) in 2020, NCERT has made some significant changes to the biology textbooks to provide a more contemporary and engaging learning experience for students. NEP 2020 states that “the reduction in the content will help in increased flexibility of school curriculum and the renewed emphasis on constructive rather than rote learning.” The new curriculum is reduced to ease the workload of the students and make for experiential learning.

The NCERT Biology textbooks will be available in at least 22 languages, mentioned in the eighth schedule of the Constitution, including Hindi, English, Bengali, Assamese, Gujarati, Kannada, Sanskrit, Punjabi, Sindhi, Manipuri, Urdu, Malayalam, Odiya, and Kashmiri, among others.

What is the basis of Content Rationalisation?
According to Union Minister of State for Education Annapurna Devi, “Overlapping with similar content included in other subject areas in the same class; similar content included in the lower or higher class in the same subject; difficulty level; content, which is easily accessible to children and does not require much intervention from the teachers and can be learned through self-learning or peer learning; content, which is not relevant in the present context or outdated and taking care of the learning outcomes already developed across the classes, are among the criteria adopted for rationalization of the content load.” Source – NCERT textbooks rationalised to compensate for Covid-19 time loss: Education ministry
