The document discusses the roles and functions of educational technology in 21st century education. It states that instruction should be student-centered and focused on applying knowledge to real-world problems to cultivate curiosity and lifelong learning. Education should also be collaborative, with students learning to work together and recognize different strengths. Technology allows for constant access to information and interaction, and can be used as a tool to aid teaching, learning, curriculum development, and more. However, technology alone is not the solution and should be integrated across classrooms as a tool rather than taught separately.
