When the pandemic forced schools to close in 2020, fourteen-year-old Daichi suddenly found himself studying from his bedroom. At first, the change seemed exciting. He no longer had to wake up early or wear a uniform. He could attend class in his pajamas. But within a few weeks, his initial enthusiasm faded, and a different kind of difficulty appeared.

Online classes, Daichi soon discovered, demanded skills that traditional classrooms had never required. Without a teacher physically present, students had to manage their own attention. The temptation to check social media during class was enormous. Some of his classmates eventually stopped attending altogether, while others appeared on screen but secretly played games. Daichi himself struggled to concentrate, especially during long lectures.

His parents, both busy with their own remote work, could not constantly supervise him. They tried to help by establishing clear rules, but Daichi was old enough to ignore them when no one was watching. His grades began to decline. Worse still, he felt increasingly isolated. The brief conversations with friends between classes, the small jokes, the shared lunches—these ordinary pleasures had vanished. He had not realized how much he depended on them until they were gone.

Yet online learning also offered unexpected benefits. Some students, particularly those who had struggled with social anxiety, reported that they could finally concentrate without the constant pressure of being watched by classmates. Students living in remote regions gained access to lectures from famous universities that they could not have attended otherwise. Recorded videos allowed pupils to review material as many times as they needed. For certain types of learners, online education was genuinely transformative.

Educators around the world have since examined what worked and what did not. Most acknowledge that simply moving traditional classes to a screen was a mistake. Online learning, they argue, requires different methods, shorter sessions, and more active participation. Teachers must learn to design activities that engage students who are physically separated. Schools must also recognize the social purpose of education. Children attend school not only to acquire knowledge but also to learn how to cooperate with peers, handle conflict, and form lasting relationships.

By the time Daichi returned to his classroom in person, more than a year had passed. He had grown taller, but he had also become noticeably quieter. It took several months for him to adjust to the noise and energy of a regular school day. Many of his classmates had similar experiences. Teachers reported that students' social skills had suffered, and that some children had difficulty maintaining attention in lessons.

The pandemic ultimately exposed both the possibilities and the limits of online learning. It demonstrated that technology could keep education going during a crisis. At the same time, it reminded us that schools serve essential purposes that screens cannot fully replace. The most thoughtful educators now insist that the best approach is not to choose between online and traditional methods, but to combine them wisely, taking advantage of each where it works best.

Daichi, looking back, says he learned something important from that strange year. "I used to think school was just a place to study," he says. "Now I understand that it is also where you grow up." That observation, simple as it sounds, captures a truth that the experience of an entire generation has confirmed.
