Please access AULIS, the E-Learning-Platform of the Hochschule Bremen and subscribe to the group Repository » Faculty 1: Business Sciences (School of Int. Business - SIB) » Int. Studies in Economics and Business Administration (ISEB MA) » Economic Research Methods (ISEB)]. We are going to use this group for our internal communication and to exchange handouts, solutions of the exercises, presentations, data, ...

The Assessment of this module is a "Learning Portfolio":
Theoretical definition from the module handbook:
   "A Learning Portfolio consists of several parts which may include individual as well as team results. Essential part of the final performance is the reflective statement in which every student critically reviews and evaluates her/his individual learning process and the roles of the different partial assessments.
   These partial assessment may be essays, concept papers, individual presentations, team presentations, reflected literature research in form of documented bibliographies, own analyses including the documentation of the applied methods, term papers, oral/written tests/exams or also other types that can be proposed to the lecturer. Normally 2 to 4 of these types are selected by the student and have to be approved by the lecturer."

Preliminary Time Schedule:    The module takes place on Tuesdays (... rescheduled to) 18.00-19.30 in D 111) and Thursdays 10.15 - 11.45 in room A 217 (at selected days in the PC lab A 131, but this will be announced in advance)

{3-4} Please recall the referencing standards we discussed

21. Presenting Results: Oral and Written Reports
 "If you steal from one author, it's plagiarism; if you steal from many, it's research" (Wilson Mizner)

Excursus: Standards for academic work / quotations:
One possibility (=there are others): "Harvard style" ->
Skills 4 Learning (C) Leeds Metropolitan University): "Quote, Unquote" Quotation guide -> more material in our Aulis-group (two zip-files, both are needed - unpack them and open index.html)
I recommend that you use
RefWorks - you can choose an appropriate standard (preferably DIN or Harvard-style), it is most important that you stick to the standard.
