Teaching methods have changed significantly over the past 100 years. In the past, teachers focused on whole-class instruction with large class sizes, making it difficult to meet individual student needs. Now, teachers focus more on individual and group learning to accommodate different learning styles. Additionally, questioning was once limited to answers the teacher could provide, while curiosity was discouraged. Current approaches emphasize developing useful questions and organizing thinking, using diagrams and encouraging curiosity. Technology is now integrated into classrooms to facilitate communication, access software, and take advantage of online resources to enhance learning in a fun way.
