--- abstract: "The article is about a new online resource, a collaborative portal for teachers, which publishes a network of prerequisites for teaching/learning any concept or an activity. A simple and effective method of collaboratively constructing teaching­-learning sequences is presented. The special emergent properties of the dependency network and their didactic and epistemic implications are pointed. The article ends with an appeal to the global teaching community to contribute prerequisites of any subject to complete the global roadmap for an altas being built on similar lines as Wikipedia. The portal is launched and waiting for community participation at http://www.gnowledge.org.\r\n" altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - nagarjun@gnowledge.org creators_name: - family: G. given: Nagarjuna honourific: '' lineage: '' date: 2009-07-20 date_type: submitted datestamp: 2009-08-13 20:05:39 department: ~ dir: disk0/00/00/65/88 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 6588 fileinfo: /style/images/fileicons/application_pdf.png;/6588/1/collaborative%2DLTS%2Dwpversion%2Dpreprint.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: ~ issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'prerequisites, education, teaching-learning seqeunces, semantic networks, concept mapping, knowledge cartography, network theory of meaning, road map of knowledge, collaborative portals' lastmod: 2011-03-11 08:57:24 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: TRUE publication: ~ publisher: ~ refereed: FALSE referencetext: "A.
