Earthlearningidea was developed, without funding, to publish a new Web-based earth science teaching idea every week during the International Year of Planet Earth (2008); during 2009, publication continued, but at monthly intervals. The activities were mostly practically based and were aimed particularly at teachers and teacher educators in the developing world, who teach in classrooms with minimal resources, and they aimed to develop active and inquiry-based learning approaches. Earthlearningidea's success is indicated by the fact that, by December 2009, 69 activities had been published, activity PDF files had been downloaded more than 110,000 times, and the blog had been accessed in 152 countries, with positive feedback from many teaching situations. Many of the Earthlearningideas had also been translated into Spanish, Italian, Norwegian, and Chinese (Mandarin). Analysis of those who accessed the Earthlearningideas showed that the majority were from the more developed world. Thus, during 2010-2011, the activities, which were published each fortnight, were created to be slightly more sophisticated than previous activities, for example, in using equipment likely to be available in a school science laboratory, or more abstract ideas. The "stop press" update shows that the success of Earthlearningidea, measured by a range of indicators, is increasing. We ask all our readers to access the site, use the activities, give us blog feedback, and "tell their friends" across the globe.
