The story was shared by Ms. Hanh on an educational forum last week, attracting the attention of many teachers.

But 5 strangers entered the virtual classroom and changed their names to the same as the students in the class, so when approving the members, the teacher did not recognize them.

The teacher panicked and tried every way to delete the stranger’s account from the class, and the lesson was then stopped.

After the incident, the teacher and colleagues proposed classroom rules and managed students in the virtual classroom more strictly.

Mr. Tran Van Minh, Geography teacher at Dao Duy Anh Middle and High School (District 6, Ho Chi Minh City) said that in the first two weeks when the school organized online teaching using the Zoom application, some strange students entered the class and harassed them.

Zoom has an approval function when students log in with their ID and password into the classroom.

Some other security solutions were told by Mr. Minh and his colleagues, such as: not allowing students to draw on the lecture when in share screen mode, turning off the sound, locking the chat function, locking the room.

In Ha Nam, Ms. Le Thi Thanh Hai, a teacher at an elementary school, received a file of instructions on how to handle strangers entering the Zoom classroom sent by the principal.

Knowing that Singapore bans the use of Zoom due to security and privacy issues, the 28-year veteran teacher said she was a little worried.

As explained by her daughter, who is a student, Ms. Hai is more aware of the risk of information leaks when using Zoom to teach online because this software requires logging in with Facebook.

`Because I don’t have a consultant, I follow my personal understanding and judgment. I’m not sure if this really helps protect personal information, but I still do it because it gives me more peace of mind when teaching

Quite knowledgeable about technology and teaching online for many years, Mr. Tran Tuan Anh, a Math teacher at the Continuing Education Center in Go Vap District (HCMC), believes that there is no software or teaching application solution.

For example, with the advantages of being easy to install, easy to log in, and simple to use, Zoom is used by many people, but this is also the disadvantage of this application.

According to teacher Tuan Anh, it is not difficult to control class members when entering an online class.

According to Dr. Quach Tuan Ngoc, former Director of the Department of Information Technology (Ministry of Education and Training), the act of handing over class IDs and passwords to strangers belongs to the student’s consciousness, this is like `handing over a key`.

Online learning is now a mandatory solution. If students and teachers want to maintain their learning program, there is no better choice.

To overcome this, Dr. Ngoc believes that students must be aware and `know how to keep their house keys carefully`.

Specifically, according to Mr. Ngoc, teaching in an interactive, meeting format like Zoom allows teachers to talk comfortably, while teaching and reminding students, so class time is redundant.

On April 13, after a period of implementing online teaching, the Ministry of Education and Training said it had received reports of bad people infiltrating the classroom, posting bad, toxic, offensive, anti-religious content.

The Ministry of Education and Training recommends that the Departments of Education and Training and schools provide training in disseminating knowledge and skills in using the Internet and social networks to ensure safety and network security when participating in online teaching.

In the 2019-2020 school year, students across the country only completed the 20th week of school, then took a break for Tet and a break to prevent Covid-19.
