What's important for the presentation

Make the presentation a cohesive and compelling story ...• Well-designed structure that enables the audience to follow the flow and argumentation

… which gets its points across ...• Many presentations are overloaded by formulae that remain unintelligible in the course of an

oral presentation• Focus on several main points that you want to make sure will stick with the audience

… while not limiting itself to trivialities• While not overloading the presentation with formulae, it should still satisfy academic levels

Time management• 40 mins for presentation (without intervention by questions) can be adequately planned

ahead

Convince by appealing and consistent visual presentation• Use the pre-defined slide templates and use bullets, fonts, bars, etc. in a consistent way• Do not overload the slides with info – the slides are meant as support for the oral

presentation!• The presentation should look good so that the audience loves to look at the slides!
