Vision Empower has been providing learning resources to many blind schools across Karnataka since 2018. These are the materials which have been helpful in teaching Science and Mathematics concepts in the classroom. These resources are curriculum-relevant and support students in the learning process by allowing them to explore the knowledge independently as well as providing repetition.

Apart from classroom materials, VE also provides knowledge enhancement and concept reinforcement practice content for visually impaired students of all grades on our online accessible open source Learning Management System, Subodha. The platform also provides Teacher Instruction Kits from Vision Empower and aggregates other helpful resources for teachers in partnership with XRCVC, Mumbai. Tutorials for Maths, Science and Digital Literacy are made available on the Vision Empower YouTube channel.

The following learning resources are created/recommended/provided by VE.

Digital Resources

Digital Literacy
Digital Literacy is as essential for teachers and students with blindness across the globe, as it is for the non-visually impaired. Unfortunately, there has been less focus on ensuring Digital Literacy among persons with visual impairment, though it has been found to improve their quality of life significantly. Vision Empower has embarked on a project along with Microsoft India to create a Digital Literacy curriculum for students and teachers with visual impairment. The feedback from teachers has been overwhelmingly positive. The tutorials are created by Vidhya Y, founder of Vision Empower, based on the extensive research she has performed to bring the much needed knowledge to the fingertips of anyone with blindness who needs them.

Teacher Instruction Kits (TIKs)

Teacher Instruction Kits for Maths and Science, created by the VE team (in collaboration with XRCVC), are reviewed by experienced pedagogic experts and special educators following the Vision Empower process. TIKs are provided chapter wise and grade wise to assist the teacher in teaching children with visual impairment. VE facilitators are always willing to support the teachers throughout the academic year to clarify any doubts and improvise on the kits.

Tactile Diagrams (TD)

Do-it-yourself (DIY) instructions for TD

Tactile graphics are non-textual information to people who are blind or visually impaired and include tactile representations of pictures, maps, graphs, diagrams, and other images.

Given below are some links which will help caregivers or instructors make Science and Math related diagrams at home by following the steps.

Spatial Understanding

Parts of a Plant

Water Cycle

Different types of Beaks of Birds

Tactile Diagram procured from Raised Line Foundation (RLF)

RLF provides tactile design and production services and is closely working with NCERT, Sarv Shiksha Abhiyaan (Govt. of India), WSSCC (UN organization) and other organization working in the field of blindness to convert textbooks, resource books, manual etc. in accessible formats along with the tactile diagrams.

Vision Empower procures high quality tactile diagrams from RLF for school students and teachers based on their specific requirements. In 2018-19, VE placed orders for specific diagrams to be designed for the EVS book for Class 5 prescribed by the Karnataka State Board. These diagrams were very useful during the pilot phase to evaluate the process of diagram comprehension by children with blindness. In 2019-20, VE evaluated the use of RLF diagrams to be used for TAG (Tactile Audio Gallery) to help children with blindness to self-learn. In 2020-21, VE has procured Science tactile diagrams for students in Grade 10.

Tactile Diagrams created by Tactograph

Tactograph, a product from Enability Foundation enables the printing of tactile books and worksheets at an affordable price. It is a motorized x-y stage that traces a predefined picture using an adhesive fluid, creating a tactile image on a normal A4 sized paper.

To make this printing process user friendly a Graphical User Interface (GUI) is developed with image recognition algorithm. This algorithm helps the teacher to print the tactile image in just four mouse clicks. VE and Enability collaborate to create tactile diagrams for Science and Math, to meet the needs of teachers and children in schools for the blind in Karnataka.

DIY instructions for models

Vision Empower works with teachers at schools to create and provide instructions for creation of specific tactile models requested for by teachers.
Early Years Tactile Resources

3-D printed models

VE procures 3D printed models from various vendors such as RLF to meet the needs of teachers at schools for the blind. VE is also working on a project to automated the creation of 3D printed models based on inputs from text book diagrams.

Mathruchhaya and VE collaboration

VE and Mathruchhaya collaborate on ensuring that Science and Mathematics Braille books are made for all students in Karnataka. In 2018-19 and 2019-20, the two teams collaborated to create meaningful content for the books which also contain tactile diagrams and Alternative text where the diagrams are not provided. The Braille Transcription Center at the Canara Bank Welfare Association, Banashankari, prints these books. VE educational co-ordinators in collaboration with school teachers proof read the books and ensure the children and teachers with blindness are provided the books during the academic year.

Science and Mathematics teachers are provided the Braille text books which are specially designed for their students and themselves, if they are blind. For the first time in the country, the teachers have Science and Mathematics books and they are excited to explore the same. Along with the books, VE provides the teachers with manuals to help them to teach the foundational concepts and text book content to their students.
