The traditional method of educating children in large groups or "batches" based on their age, grade, or level is still used because it is a convenient and efficient way of organising a large number of students. However, it may not necessarily be the most effective way of educating children, as it does not take into account their individual needs and abilities. There are alternative methods of education, such as personalized learning, that aim to address this issue by tailoring education to each individual student.
Personalised learning involves using technology and other tools to create a customized learning experience for each student. This approach has been gaining popularity in recent years, as it allows students to learn at their own pace and in a way that is best suited to their individual learning style. It also allows teachers to better track the progress of each student and adjust their teaching methods accordingly.
However, personalised learning is not without its challenges. It requires a significant amount of time and effort to develop and implement personalised learning plans for each student, and it may not be feasible in all educational settings. Additionally, some critics argue that personalised learning may lead to further social isolation and inequity if not implemented properly.
Overall, the question of why we still educate children by batches is a complex one with many factors to consider. While personalised learning is a promising alternative, it is important to weigh the potential benefits against the challenges and limitations of this approach.
