With covid in the picture, online learning was widely used worldwide for students in school as well as in college/universities. Although, online learning saved time and energy, required for travelling to school and back home it had various disadvantages attached to it.
In my opinion traditional in-person classes are more effective as compared to online classes. Traditional classes keep the students active and help them to focus more in studies. On the other hand, online classes make students lazy. Most of the students would log in to their online lectures and go back to sleep or play games or engage in activities other than studying. This resulted in the students not learning anything about the subject.
Students would also cheat on their tests when they were conducted online as there would be no supervision by teachers. Overall, students would not gain any skills or knowledge neither theoretically nor practically.
Thus, in my opinion, traditional in-person classes will always be more effective than online classes. It also enables the students to interact with each other and develop other soft skills along with learning and studying while gaining knowledge. It helps them stay active rather than sit inside their houses.
