PRESENTATION GUIDELINES

Presentation time should be 10 minutes (it's very important that you do not go over this time). We will have 5 minutes for questions and discussion. It's also important that all non-presenters read the papers carefully before the session as this will make the discussion much more interesting.

Your presentation should provide background to motivate why the research was conducted, describe the key results of the paper (not necessarily all of the results) and the essence of the measurement method, and explain the significance of the results to the general field. Remember that 10 minutes will not be nearly enough time to discuss every aspect of the paper so you will need to identify the most important aspects to include in your presentation.

Make sure to upload a Powerpoint or PDF file of your presentation the day before the meeting so that we can use only one computer to avoid connection problems.

Feel free to see 20.309 staff outside of class to discuss any questions or ideas that you might have about the paper.
