High school uses 3D technology to teach maths

HCM CITY — Lê Quý Đôn High School in HCM City on Tuesday began using  三D technology to teach mathematics for  一 一th grade classes.

According to the municipal Department of Education and Training, the school is the first in the city to use machines with interactive screens, projectors and  三D glasses to teach maths.

Hà Hữu Thạch, the school rector, told Sài Gòn Giải Phóng (Liberated Sài Gòn) newspaper that the  三D projection room was put into use at the end of the  二0 一 九- 二0 二0 school year.

Many schools have also been using  三D technology to show documentary films to support the teaching of social sciences such as history and geography.

The equipment is especially helpful in teaching subjects such as spatial geometry, Thạch said.

Nguyễn Hoàng Thanh Trúc, a maths teacher, said that lessons use real-life situations.

“Students encounter the problem of cross-section of shapes, for example, in real life in fields such as mechanics, engineering and others. The school’s team of maths teachers designed a lesson with  三D technology, helping students to observe visually and vividly the cross-section of shapes,” Trúc said.

Compared to teaching in  二D format on paper,  三D lessons require teachers to spend time studying and finding tools that convert  二D to  三D format to display on the projector screen. 

At first, teachers had difficulty because not all  三D formats are compatible with  三D glasses. However, with perseverance and a trial teaching period, the teachers were able to complete the  三D lesson plan.

After the first lesson with  三D software, many students said they were excited about studying. The shapes in space were no longer abstract and ambiguous on paper, but instead were animated.

In the coming time, the school will continue use the  三D format in other subjects such as chemistry and biology. — VNS
