This is in no way an absolute description how to present but rather pointers that might help you present better.
Work with time – you have a time limit of 10 minutes, use them well. We will show you a yellow and red sign when you will be nearing the end of the set time limit (in online version of the seminar we will tell you). Try to plan your presentation in a way that you manage to go through all the most important points.
We are evaluating number of things during your presentation, but it can be summarized into groups: content of your presentation, style of your presentation.
Content of the presentation – try to use the general scientific approach. This means that you identify a problem area, set a goal, present data, and draw some conclusions. We are also evaluating the style of your PowerPoint presentation.
Style of the presentation – generally speaking, we are evaluating your verbal and nonverbal communication. Verbal communication includes the way how you speak (never read your presentation from a paper), how you work with the audience. Nonverbal communication includes things like attitude, gestures, smiling, eye contact etc.
There is a lot of content online describing how to present, we can recommend these videos here, here and here.
