The document discusses how technology has changed classrooms from the past to the 21st century. Early classrooms relied on chalkboards, films, and television for presentations, while today every student has access to computers and uses tools like PowerPoint and smart boards. In the past, classrooms focused on repetition and compliance from students, whereas now they emphasize engagement, problem-solving skills, and preparing students for their future. Technology allows for project-based learning, quick research, and helps all types of learners access information. While technology provides benefits like increased engagement and information access, it also presents challenges like reduced social and handwriting skills from over-reliance on computers.
