Tomorrow (9th) Middle and high schools nationwide will start online at high school and middle school.

On the 16th, the first and second graders, the first to second graders, and the fourth to sixth graders begin their remote classes. On the 20th, the first to third graders start online.

Remote classes are conducted in three ways: 'real-time interactive', where classes are conducted through real-time video connection, 'content utilization', where video classes such as EBS are viewed and discussed, and 'task performance', which presents tasks such as reading. .

Each teacher adopts a teaching method from three types, taking into account his or her curriculum, school conditions, and student grade.

Depending on the teacher, two or three types can be mixed.

Either way, 'teaching' and 'learning' are done remotely.

It is the first time that all classes are conducted remotely, and the troubles are from the remote teaching tools used for teaching and learning.

The first concern at school was whether there were enough tools for students to learn.

At least one smartphone is required for remote classes, and a smart pad, laptop, or desktop computer is required to attend classes on a large screen.

The Ministry of Education surveyed how many elementary, middle, and high school students who do not have a device to take remote classes through the National Metropolitan and Provincial Offices of Education, and found a total of 223,000.

This is the number collected as of the 31st of last month when the Ministry of Education confirmed the opening of elementary, middle and high school online.

It is likely that the investigation has not been carried out closely, such as a multi-child home student who has only one computer at home and does not know that all of his brothers and sisters are going to take a remote class and responds that there is a device.

An official from the Ministry of Education said, "We are grasping the demand for devices in more detail by region."

The Ministry of Education has secured a total of 321,000 smart devices to lend to students who do not have a device, so they will not run out of devices.

The metropolitan and provincial offices of education and schools have stocked 230,000 units, the Ministry of Education has stocked 55,000 units, and Samsung Electronics and LG Electronics have donated 36,000 units.

We decided to rent the equipment as a top priority to low-income families such as those eligible for educational benefits, and rent it at the discretion of the school principals to multi-children, single parents, and grandchildren.

However, there is a voice that students who are unfamiliar with smart devices, such as elementary school children of single parents and grandchildren, should not only provide devices, but also provide additional support for human resources.

The True Education Parents Association delivered a statement to the Minister of Education yesterday and suggested that "After school, a lecturer or college student should be sent to the home as an 'online learning helper' to prevent blind spots in learning."

Teachers' tools for teaching also seem unstable even before they start online.

The representative worry of teachers is the 'learning management system' (LMS).

Regardless of the type of distance learning, an LMS is required for teachers to notify and share learning materials and assignments and manage attendance.

The LMS provided by the educational authorities includes the e-learning site of the Korea Educational Academic Information Service (KEIRS) and the 'EBS Online Class' of EBS.

You can check the progress of students by linking each site content and class.

However, the e-learning site had an accident where all the data uploaded by the teachers disappeared from 2 am to 9 pm on the 3rd.

The number of people connected to the time zone was about 80,000.

Teachers have lost their learning materials, lecture plans, and assignments that were posted during this time in their online classroom.

EBS online classes also have complaints that sometimes access is not smooth.

On the 23rd of last month, I started an EBS online special lecture, and there were times when access to both EBS primary and secondary sites was impossible.

As the LMS provided by the authorities is unstable, teachers are turning to private companies programs such as 'Class 123' and 'Google Classroom'.

A high school teacher in Jeonnam said, "Young teachers who are familiar with computers are proficient in dealing with private programs, but teachers with seniors are not only remote classes, but also LMSs for the first time." There is an inevitable gap between teachers. I did.

Video conferencing programs for real-time interactive classes are also anxiety for teachers.

Education officials have recommended using zoom because the video conferencing program 'Zoom', made by American companies, is easy to handle and versatile, but recently in the United States, zoom has been found to be very vulnerable to security.

When New York City, USA, had a videoconference with zoom, it was confirmed that a series of pornography incidents appeared on the screen, and recently all schools in New York were instructed to stop using zoom.

Due to infrastructure problems, many schools decided not to give up real-time interactive classes at all, or only a small part, and to do only one-way content-type and assignment-type classes.

A high school teacher in Gyeonggi-do said, "As a result of the teacher's meeting, we decided to focus on providing EBS content and attach some interactive classes." If the Ministry of Education decided to start school online a little earlier, it would have been better for the school to prepare more faithfully. " .
