What is the differences between schools in the 19th century then the 21st century?

Schools in the 19th century typically emphasized rote memorization and were often rigid in structure, with limited resources and a focus on basic literacy, arithmetic, and moral instruction. In contrast, 21st-century schools prioritize critical thinking, creativity, and technology integration, offering a more diverse curriculum that includes arts and sciences. Additionally, contemporary education often promotes collaborative learning, inclusivity, and personalized instruction, reflecting a broader understanding of student needs and learning styles. Overall, the shift has moved from a one-size-fits-all approach to a more student-centered model.
