Another 21st Century theme is creativity. Sir Ken Robinson has written and talked at length about the need to encourage and develop creativity in schools. He talks about how children come to school with loads of creativity and how schools effectively eliminate that in this book (Out of Our Minds: Learning to be Creative) and in the video below. You can also find a great interview on the ASCD website.
One of the most common ways we can encourage creativity in our students is providing them with opportunities to write. And with today's technology, that activity can go far beyond a simple pen and paper exercise. This link provides some great iPad apps that are available to create full multimedia ebooks that can be easily be shared with each other, parents and grandparents, etc.
