Wiki-centric extended classroom

Setting up a wiki (http://exploringgeography.wikispaces.com/) gave Class 10 Geography students extra opportunities to post and edit their work – lessons, links, handouts, presentations, videos, games – online, thus allowing me and fellow students to provide comment and feedback. The students were divided into four groups:
(i) Q for asking questions,
(ii) A for answering questions,
(iii) E for enhancing/adding to A’s group answer and
(iv) P for paraphrasing and summing up E’s group.
The groupings were changed for each activity to ensure that the students had a chance to take on a different role. The wiki was also used to share day-to-day information and instructions, including a variety of resources provided by both the students and me. Replacing time needed for traditional homework, the wiki enabled the students to concentrate on exploring and learning new concepts.
