The practical implementation consists of 30-60min presentations on the personal research topic AND active discussion in terms of two student "opponents" (compare to actual PhD thesis defence) per presentation. The idea is that each participant should give three presentations during the graduate studies:
For the student "opponents", a written report should be delivered well in advance of the presentation date such that the opponents can familiarize themselves adequately with the topic. The main point in this whole opponent process is to try to get some synergy benefits by looking at the particular research problems with open and new eyes and getting really fresh input and feedback.
In general, the presentations and the reports should have a scientific style and should cover the previously mentioned aspects of the graduate studies and the research problem. The exact subject and the contents of the presentations should be discussed with the advisor(s) of the doctoral studies.
Active participation, three own seminar presentations, acting as opponent for other participants (min. 6), and written reports.
The number of credit points obtained depends on the seminar attendance
Notice that the seminar is generally meant to cover the whole period of graduate studies (on average 3-4 years or so), so the attendance requirements for obtaining the credits are not that tough, right :o) ?
people already close to graduation, contact the course responsibles for possibilities of having individually formulated credit point requirements
