A 21st classroom should have--at a bare minimum--a laptop or computer for the teacher, a projector, a document camera, and enough tablets or computers for students to work in groups of 4 or 5 in centers or stations. This way, each child gets to work on a machine on their own while other students are working at different stations. This works very well in my Kindergarten field experience that I'm currently taking part in.
An ideal 21st century classroom would have a machine for each student and for the teacher. With one to one computing, it would open a whole new door for teaching. Kids could have their own blogs and have their own machines so things wouldn't have to be done in "stations." Ideally the classroom would have computers AND iPads. This way, the Apps could be downloaded onto the iPad and used as educational enrichment tools. Computers would be available as needed for word processing and research. Having them be incorporated into the desk and able to turn on when needed would be very cool.
A 21st century teacher should have a smart phone or a computer/tablet. This way they can be connected to their grade book and e-mail as needed. This would also help them be familiar with the technology their students are using.
A 21st century student should have access to a computer/tablet/smart phone and the internet. I'm not saying each student should have their own machine with the internet. However, they should have access to something so they can complete online assignments and be familiar with the technological world.
