Delhi University makes arithmetic easier for blind students

The Delhi University has developed specialised “mathematical kits” to make solving numerical problems less taxing for visually-impaired students. The university is also planning to carry out a nationwide campaign in which students and teachers will visit various blind schools, distribute the kits to the students and conduct workshops to teach them how to use these.

A senior DU official said that in the second phase, after receiving feedback from various quarters, the university plans to recommend to HRD ministry for inclusion of the tools in the curriculum. The kits have been developed by four DU students pursuing M.Sc. Maths in consultation with experts and two professors, Jyoti Sharma and Pankaj Tyagi.

“We conducted a survey at various blind schools in Delhi and found out that the only specialised technique available for their teaching is Braille. Few schools use audio mediums too. These can be helpful in teaching literature or other subjects, but not maths, which is very complex,” said Madan Chaturvedi of DU’s Cluster Innovation Centre.

The kit has been divided into three parts. The first one contains geometry tools which include specially-designed scale, protractor, compass, and a board. Braille technology has also been used to make the tools. The second part includes shape-based abacus, which is different from a routine abacus. The third segment is Braille designed board for multiples and factors.

“Apart from this, we have also included a snakes and ladders game, especially designed to suit the needs of the blind. The game will help the users get a hang of how to use other tools,” said Prof. Sharma.

The tools were also tested by students of three blind schools. “We plan to validate the tools by seeking feedback from a large sample size and then approach experts for advice on any rooms for improvement,” added Prof. Sharma. After completion of the first phase, the varsity also plans to introduce the product commercially in the market.
