a sort of Teacher Response System (TRS)—designed to support decision-making,reduce friction, and enhance teacher-student responsiveness in real time

When a tool fails to adapt to a teacher’ssituated needs, it risks undermining both instructor agency and the student empower-ment it exists to support.

The slow uptake of such a seemingly promising tool may lie in its fundamental asym-metry

COVID-19 constituted 29% of deaths from June 2020 to July 2021. This corresponds to 32 lakh deaths, of which 27 lakh occurred in April–July 2021.

India was the highest (5.8 times) and only Chile (5.7 times) came close.

Excess deaths analyses based on deaths registered in the Civil Registration System (CRS) have shown that they have been as high as six times the official death toll for just 11 States and Union Territories (Maharashtra, Punjab, West Bengal, Tamil Nadu, Kerala, Karnataka, Himachal Pradesh, Haryana, Delhi, Madhya Pradesh and Andhra Pradesh) for which such data was available.
