One area that I think is often overlooked by educators thinking that they already have a full curriculum, is that some skills need to be taught in different contexts for today's children. In the 21st Century Content section, the website lists Several significant, emerging content areas are critical to success in communities and workplaces. These content areas typically are not emphasized in schools today:"Global awareness, Financial, economic, business and entrepreneurial literacy, Civic literacy, and Health and wellness awareness" as "significant, emerging content areas [that] are critical to success in communities and workplaces". Teachers can use technology to teach geography, history and global awareness as one, with more emphasis on global and cultural connections and relevant current events than latitude and longitude.
It seems like the curriculum doesn't need to change as much, just our methods and perspective. With my first graders, instead of just mapping the classroom or the intricate neighborhood, we use maps of Central America, where 90% of them are from, and find it on the globe, and use technology to explore geography in other ways. Critical thinking, connections, problem solving, all of these skills can be enhanced by technology, and this website has a great way of explaining how to do that.
