The service is predominantly accessed through the mobile social networking service MXit. Since 2007, students from the Faculty of Engineering, the Built Environment and Information Technology (EBIT) at the University of Pretoria, have been assisting \u201cDr Math\u201d in fulfillment of a compulsory undergraduate module, Community-Based Project. They have supported 28,000 registered users in user initiated interactions. This purpose of this paper is to describe the mobile scaffolding environment and scaffolding practices as well as the tutor support that enhance the Dr Math service as a sustained example of mobile learning.<\/p>","DOI":"10.4018\/jmbl.2012040102","type":"journal-article","created":{"date-parts":[[2012,3,29]],"date-time":"2012-03-29T09:35:04Z","timestamp":1333013704000},"page":"15-29","source":"Crossref","is-referenced-by-count":13,"title":["Dr Math"],"prefix":"10.4018","volume":"4","author":[{"family":"A.Botha","sequence":"first","affiliation":[{"name":"CSIR Meraka Institute, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Butgereit","sequence":"additional","affiliation":[{"name":"CSIR Meraka Institute, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"jmbl.2012040102-0","doi-asserted-by":"publisher","DOI":"10.1007\/s10857-006-9005-9"},{"key":"jmbl.2012040102-1","doi-asserted-by":"publisher","DOI":"10.1007\/s11251-005-1273-8"},{"key":"jmbl.2012040102-2","unstructured":"Botha, A.
