NCERT to introduce QR code in textbooks
The National Council of Educational Research and Training (NCERT) has initiated process of introducing QR code (Quick Response code) in their textbooks. It is aimed at helping students understand chapters better by watching film or reading additional content on laptops and digital boards.
For this enhanced learning feature, NCERT has started process of identifying relevant supplementary material including videos, power point presentations animations, maps and e-content. These will be mapped with content of each textbook from class 1 to 12 and will be linked with QR code, which will be printed in the textbooks. The QR code laden textbooks are likely to be introduced from the 2019 academic.
QR code (Quick Response code)
QR Code is a two-dimensional (matrix) machine-readable bar code consisting of an array of black and white squares, used for storing web-links or other information. This code can be read by camera of smartphone. It is used for storing URLs or other information that link directly to text, emails websites phone numbers. It is capable of 360 degrees (omni-directional), high speed reading. It can store up to 7089 digits as compared to conventional bar codes which can store max 20 digits. It encodes same amount of data in one-tenth the space of a traditional bar code. It carries information both horizontally and vertically. It has error correction capability and data stored in it can be restored even if it is partially damaged or dirty.
