Nobel laureate Abhijit Vinayak Banerjee Wednesday said the lockdown has impeded the basic learning of students and schools in West Bengal should reopen as soon as possible in view of the present COVID situation. The economist, who heads the Global Advisory Committee formed by the West Bengal government to combat the coronavirus situation, also underscored the need to curtail the curriculum once the classes resume at the junior level and help children make up for the lost time. The Mamata Banerjee government has launched the 'Paray Sikshalay' programme, which is open air sessions for students from pre-primary level upto class seven in every locality from February 7. It is aimed at honing the vocabulary and numerical skills of students, besides story telling, rhymes, song and dance as well as classes in different subjects. Observing the standard operating procedures and temperature check of everyone present at these programmes are mandatory, officials said.
