So far, learning is carried out face-to-face with various activities in it which are also carried out face-to-face. Group activities are also very easy to carry out. The online facility is only used for the purpose of sending emails or just sending assignments. Right in March 2020, when WHO declared Covid-19 a pandemic, it had a huge impact and was felt by various countries in the world, including Indonesia. Indonesia, which has cultural roots to meet each other, face to face suddenly has to change its activity pattern from offline to online. This causes problems in various sectors, including the education sector. Schools are forced to move their learning activities from classrooms to virtual spaces. Starting from how to teach, how to evaluate, how to give assignments, the types of assignments given have all changed. Teachers, students, and parents complain a lot about the lack of learning activities. Online learning that is held must be able to achieve and develop 21st-century competencies in students, such as critical thinking, creative thinking, collaborating, and communicating equipped with literacy skills. Over time, online learning that is carried out seems far from achieving this. Learning tends to return to being teacher-centered, assignment activities are more likely to be carried out individually. The reason is that teachers find it difficult to carry out collaborative activities online, both for the learning process and the form of assignments. As a result, there has never been real-time collaboration during the online learning process. This is certainly very contrary to the objectives of 21st-century learning, one of which emphasizes collaboration.
