The Government school for blind in Ranchi has 24 visually impaired students aged between 6-18 years.

These 24 students each are taught for 60 minutes by 2 teachers.

This meant that students would receive only 5 minutes of hand-holding and personal attention. This is inadequate for learning Braille.

Students were spending the remaining time either waiting or attempting exercises with minimal feedback.

This teaching method was inefficient for attaining the required learning outcomes and demotivated both the teachers and the students.

This is the story of many schools in India.

Problems Identified

The unfavorable student to teacher ratio led to the students receiving inadequate supervision.

The lack of interactive content failed to pique the student’s interest and keep them engaged. As a result of this, students were taking longer to learn Braille.

These learning outcomes did not align with what the dedicated teachers set out to achieve.

The Solution

To address the pain points of both the teachers and the students, India’s first Braille smart class was deployed in Ranchi.

20 Annie devices were set up to teach braille to the 24 visually impaired students in the school.

Their user profiles were created to help their teachers track their usage and monitor their progress through lessons and tests.

A server was set up to sync with the user progress data and release over-the-air content and software updates.

The Result

The response of the 24 students has been overwhelmingly positive. The younger students especially are showing great enthusiasm in using the devices to learn.

Teachers could now view students' usage and track their progress.

Annie was received with great enthusiasm by the teachers as they could now monitor 24 students at the same time and achieve the learning outcomes.
