Seminar Opening

The seminar opening took place on Thursday, 18th October 2018.
If you have not done this so far, please register in the VSR Seminar Workflow System.
The slides of the seminar opening are available here.

Short Presentation

The short presentations took place on 12 Nov 2018.

In your short presentation, you will provide a brief overview on your selected topic.

This includes the following aspects:

  1. What is in your topic?
  2. Which literature sources did you research so far?
  3. What is your idea for a demonstration?

The short presentation should be no longer than 3 slides (in addition to your title slide) and take max. 5 minutes. Following your short presentations, the advisors will provide you with feedback and hints for your full presentations.

Hints for your Presentation

  • As rule of thumb you can plan for 2 minutes per slide. Significantly more slides per minute can be difficult to perceive for the audience.
  • Prior to creating your presentation, you should think about: What should be the main message of my presentation? What should the audience remember after my presentation?
    Based on these considerations you should create your presentation.
  • Here you can find some useful hints http://www.garrreynolds.com/Presentation/
