Joho the Blog » Internet not the child-devouring swamp many adults fear - 0 views

  • A three-year research project, headed by Mimi Ito, involving 28 researchers and 800 subjects, and sponsored by the MacArthur Foundation, finds that the stereotypical idea of the Internet as a soul-devouring, anti-social wasteland for our kids is just plain wrong. If you suspected otherwise, now you know you were right.

World Without Walls: Learning Well with Others | Edutopia - 1 views

  • Welcome to the Collaboration Age, where even the youngest among us are on the Web, tapping into what are without question some of the most transformative connecting technologies the world has ever seen. These tools are allowing us not only to mine the wisdom and experiences of the more than one billion people now online but also to connect with them to further our understanding of the global experience and do good work together. These tools are fast changing, decidedly social, and rich with powerful learning opportunities for us all, if we can figure out how to leverage their potential.

  • 由圣迭戈同名公司KidZui提供的这项服务声称它能向儿童们提供50万条与无害网站、图片和视频的链接,被链接的内容涵盖了从流行文化到科学、从搞笑作品和游戏到历史的诸多领域。儿童们通过这项服务可观看《美国偶像》(American Idol)的最新竞逐,了解有关恐龙的知识,探索历史或访问网娃(Webkinz)和企鹅俱乐部(Club Penguin)等知名儿童网站。
  • 这项服务可以对儿童用以上网的电脑进行有选择的设置,以确保儿童不能脱离KidZui通过电脑的标准浏览器上网。父母可以将KidZui设置为电脑启动后自动以全屏模式出现在屏幕上。在这种模式下,KidZui能让那些可使用户转向或启动其他程序的按键、图标、指令和手法自动失效,或将其隐藏。
