The SEFI (European Society for Engineering Education) Mathematics Working Group (MWG) was established in 1982. The aims of the Working Group include providing a forum for the exchange of views and ideas amongst those interested in engineering mathematics, and promoting a fuller understanding of the role of ma­the­matics in the engineering curriculum, and its relevance to industrial needs. The Working Group issued the third edition of its curriculum document (“A Framework for Mathematics Curricula in Engineering Education”) in September 2013. In summer 2016, the 18th SEFI MWG seminar will be organised by Chalmers University of Technology in Gothenburg, Sweden. The overarching theme of the seminar will be the concept of mathematical competencies. This includes in particular the following issues:   Transition to higher education for traditional and adult learners Learning mathematics through project work Mathematical competencies in web-based learning scenarios Using technology to improve mathematics education Other contributions related to the mathematical education of engineers are also welcome. Note: Abstract submission deadline has been extended to Januari 31. Keynote speakers will include: Tom Lindstrøm , University of Oslo, Norway Jana Madjarova, Chalmers University of Technology, Sweden Mogens Niss, Roskilde University, Denmark
