Dear students,

Today will be the last lecture of this semester. In the first part of the lecture, Matthias will talk about usable privacy and then we will briefly revise the course content to prepare for next week's exam. You will again have the chance to ask questions on the course content.

CISPA is currently shooting an image film and our lecture will be part o this film. Therefore, a camera team will join us during the Q&A session to record a few minutes of our lecture. If possible, please stay with us for the video shoot (the larger the crowd, the better). If you do not want to be filmed, that's fine too. Just let us know and we will either assign you a seat where you are not visible or you may leave the course earlier. If you have any questions or do not feel comfortable during the lecture or video shoot, just let us know!

Thank you very much for your cooperation for the video shoot. And again, thank you so much for being such a great audience during the entire semester.

Have fun explaining key verification to a person who is not a computer scientist :)

Clarifications on the Coding Process in Assignment 2

Dear students, we are sorry, there was a typo in Section 5 of Assignment two.

"Forward your coded transcribed interview and your codebook to one of your fellow students. You should get their interview and codebook in return. Do not share your coded data with them as two coders should code the data independent from each other! Code your partner’s interview using their codebook and send it back to them. Try to do this step quickly, since your partner cannot continue their work until you are done."

We have uploaded an updated version to CMS.

If you have already shared your coded interview with your interview partner, please send them your data without the codes you assigned. In real life, it would be suboptimal if your partner has already seen your coded data (as coders would not independent). For this assignment, this is not a problem as the learning experience is what counts!

 

 

 

Clarifications on the Interviews in Assignment 2

Written on 20.05.19 by Matthias Fassl

Dear students,

since a few students have contacted us and said that their interview was 5 minutes or shorter we had an internal discussion about the importance of the length of the interview.

We came to the conclusion to set a minimum length of 8 minutes. If your interview is too short, please either ask more questions or interview a second person.

Be advised that one of the learning goals of this exercise is to find out what kind of questions elicit which kind of responses. If you discover that some of your questions are hard to understand or lead to very short answers you can and should change them.

 

Kind Regards,

Matthias Fassl
