An Abacus as Visual Aid Tool
An abacus is a counting tool that is designed with rows of colorful beads or same-colored beads strung on roads and it is fixed inside the rectangular frame kind of box. It actually serve as a manual calculator and it is used for calculating arithmetic mathematics calculation like addition, division, subtraction and multiplication. Abacus allows children to manually use hand to understand numbers and tactile mathematical operation.
How
Abacus is used by visually impaired people or learners?
1. Touch-based learning: People who are visually impaired rely on feeling or touching the beads to move the beads and count. Those people who are visually impaired can get equal opportunity to learn as others who ain't visually impaired as they can depend on the Abacus to do the manual calculations. The abacus is kept flatly on the surface and their fingers can use it to slide the beads up and down to manually count. Such learning styles provides quick feedback helping the learners to understand the numeric values.
2. Tactile learning: learners can touch the bead positions alike place value charts like, tends, hundred and units. through such they can perform calculations like multiplication, addition, division and subtraction. The structure of the abacus plays a role alike the place value chart (ones, tens, hundred, etc...) so learners can manually distinguish between different columns and rows in order to understand how each represents a various numerical value.
3. Allows independent learning: One of the most significant advantages of the abacus is that it actually promotes independence. The abacus allows learners who are visually impaired to perform calculations without sighted help or through devices which will allow participation for themselves. This generates confidence and self reliance in their own capacity to work on basic level of mathematical operations.
What
it is used for?
The Abacus is widely used in the field of education and in cognitive development programs. An Abacus is usually used by visually impaired learners in learning as it functions more than just a counting device, like it is an accessible and helpful educational tool. And to go with learning fields :
1. Mathematical calculation learning: Abacus assist in basic arithmetic operational calculations through physical or hands-on approach. So, learners develop real concrete understanding of numbers and operations.
2. Active cognitive development: After several physical calculations, overtime learners build the ability to transit from using manual calculation to mental which enhances thinking skills development, high memory retention and
concentration.
3. Alternative to Digital Devices: it’s a non-electric assistive tool that is reliable or teaching and learning mathematics. This gives opportunity to eve those who don't have access in electricity and to place where digital access is limited.
Advantages of using Abacus
1. Hands-On Learning: Enhances practical method
learning through physical touch and understand mathematical concept.
2. Inclusive tool: This tool can be used by all ages
and all type learners assisting people with different abilities.
3. Non-electric instrument: No power or battery is
required so it works anywhere.
Disadvantages of Abacus:
1. To learn mathematics using abacus will be maybe
hard for few because it need constant practice and guidance to learn certain techniques.
2. Not suitable for higher level of mathematic
calculations and other various subject learning.
Where Abacus can be used?
1. School Learning Centers: Abacus can be used in
helping learners learn to count, place value and calculations.
2. Special Education Program: Schools and Learning
Centers: Abacuses are widely used in programs for visually impaired
learners. The tactile aspect allows them to “see” math through touch.
There are additional features in
Modern Abacus Programs: we have like Braille Abacus, where it is designed with
tactile marks for blind learners. There's Digital Abacus Apps which takes place
through virtual versions for tablets and smartphone. It is even color-coded
beads to make learning easier for young children.
Conclusion
The abacus is not just a tool from the past it’s a meaningful aid for learning and accessibility. I believe it helps make math more understandable and enjoyable for visually impaired learners and those who require tactile support. Whether for young learners or the visually impaired, the abacus remains a simple yet powerful device in inclusive education and cognitive training. Abacus remains one of the bridging materials between traditional hands-on learning with modern educational needs
