A teacher in Ho Chi Minh City makes a math model for a blind student.

To help visually impaired students visualize spatial geometry, Ms. Pham Thi Thanh Tam and her students spent 12 months researching and creating mathematical models.

Ms. Pham Thi Thanh Tam (Tran Phu High School, Tan Phu District, Ho Chi Minh City) said that during her teaching, she noticed that 11th grade students had many difficulties in imagining spatial geometry. For visually impaired students, this was even more difficult.

"We have built a set of realistic, intuitive, and vivid mathematical models. The model helps students visualize spatial geometry and thereby solve problems. For visually impaired students, the model can be held, grasped, built, and felt," said Ms. Tam.

The model set includes a wooden base (considered as a plane), nodes (as points), and strings (considered as edges). There are also antennas to make vertical prisms and oblique prisms that can change length and height. The model also includes spheres, ellipses, connectors, and cylinders.

After the model won third prize in the city-level student startup idea contest and second prize in the 6th national student startup idea contest, Ms. Tam and her students donated it to Nguyen Dinh Chieu Special High School (District 10, Ho Chi Minh City).

Nguyen Yen Khoa (student of Suong Nguyet Anh Secondary and High School, District 10, Ho Chi Minh City) shared: "I really like learning this model. My eyes cannot see, so when I learn, I can touch, feel, and imagine the regular triangular pyramids and regular quadrilaterals. In addition, I also experience constructing the model like doing exercises."

Mr. Nguyen Viet Thang - a blind teacher at Nguyen Dinh Chieu Special School, District 10, Ho Chi Minh City - said: "Blind students cannot see or touch the 2D plane when learning spatial geometry. Therefore, the subject requires models for them to directly contact, feel the space and enjoy the subject. The research team wrote the embossed letters on the model. I am very happy and feel the love of the research team for blind students."

'Mobility guide' for visually impaired students

The image of a teacher holding the hand of each blind student to guide them up and down stairs, across the street, and avoid obstacles... has become familiar to people on Nguyen Chi Thanh, An Duong Vuong, and Ngo Gia Tu streets...
