I found it interesting that the text book commented on the fact that schools and teachers at one time "owned" the content of the curriculum. The curriculum being taught only from the text with few outside resources. Students did not have much outside information available to them. I remember when I was in school and doing a research paper, we had the encylopedia and books at the library. It took a long time to research and find the information.
Today, students are able to go online (teachers also) and get so much more information and it is fast.
The text also talked about how the way of teaching is changing to more open source and that everyone can contribute to the curriculum. We have access to other teachers today, in ways we never had before, we can get our lesson plans online, or view things that worked or did not work in other classrooms.
Students have the opportunity to share their work with others via the web. Isn't that a great incentive to complete a project? Before only the teacher saw the hard work put into an assignment but today it is possible for many to view it. Students can also work together on projects that they would have had to meet in person in the past. Today, they can do a whole project and never meet face to face.
