The 21st Century Classroom

Describe the differences between the 21st century classroom and the classrooms of 10 or 20 years ago.
It seems that the biggest difference between the 21st century classroom from its predecessors is that 21st century classrooms focus on students developing multiple intellectual skills as opposed to acquiring information and studying techniques. A shift from students learning from the teacher about specific subjects, to students and teachers learning HOW to learn and solve problems using different mediums and communicating ideas/solutions creatively via multiple platforms and technologies. Due to the rapid evolution of technology during the 21st century, classrooms now have the opportunity to gather information from more than just a text book, and do more than just listen to their teacher lecture. These technologies do not just provide more opportunities and accommodations to education, but also make their implementation in education a necessity because of the demand for technology literacy and creative thinking/communication skills in the 21st century workplace.
In the 21st century classroom, students are provided with multiple ways to learn, and are required to communicate their knowledge and needs with their classmates and to the teacher. Teachers are required to be flexible, well-prepared, observant, open-minded, and up-to-date on their teaching content and methods. In past classrooms, the students were required to listen to their teacher and retain the information being taught. Now, both the students and teacher are required to be observant and respectful of each other to produce a more interactive and stimulating learning environment. Instead of being assessed on how well they retain and apply information, students of today's classrooms are also assessed on skills such as team-work and communication through group projects and class discussions.
