"The challenge is children are coming to schools and not being able to adapt language skills. The system has failed in teaching the children how to read, learn and express in language. This makes it difficult for them to use the language in other subjects as well. When a child finds it difficult to read a language, he will find it difficult to learn social science, science and other subjects in that language," Atishi Marlena, former advisor to Delhi Education Minister Manish Sisodia, told IANS.
