12. Your presence and active participation in the lectures is essential
Pedagogical method
I will lecture about half the time
We will study user interfaces together and perform evaluations ‘live’
You will read research papers and we will discuss them together
Everybody will study all the papers
One student will start the discussion by summarizing the paper
You will do course assignments & projects, and present the results
Topics include, UI design, UI evaluation, experiment, research
Course language (as in the entire M.Sc. Program) is English
We may speak / communicate in Greek, during the class, BUT all written material (class notes, handouts, projects, exams etc) will be in English
Your presence and active participation in the lectures is essential
- and carries a 10% contribution to your final grade -
Usability Engineering - Course Description

13. Papers for student-led discussions 1/3
In a couple of weeks I will prepare a list of papers (published research papers and/or related articles) for you all to read and discuss in class.
Each student will lead the discussion of one or two papers
me to choose up to five of them for which you wish to lead discussion
If nobody volunteers for a particular paper, I may assign it.
Students who volunteer to lead the first two discussions get a bonus
Read all the papers, not just those you will be presenting
Usability Engineering - Lecture 1 13

14. Papers for student-led discussions 2/3
When you discuss a paper you should orally tell the class:
The main point of the paper (1 minute)
The methodology the authors used (if appropriate 1-2 mins)
The results they obtained (if appropriate 1-3 mins)
The conclusions they drew (1-2 mins)
Any threats to validity of the conclusions that you see (1 min)
What you liked about the paper and/or agree with (1-2 mins)
What you didn't like about the paper and/or disagree with (1-2 mins)
Time limit: 10 minutes to quickly discuss the above
(But 5 minutes would be OK if you can say enough interesting things)
Another minutes for comments / questions from the class
Usability Engineering - Lecture 1 14

15. Papers for student-led discussions 3/3
Do not ‘read’ pre-prepared material
Talk from point-form notes you have prepared
No PowerPoint slides
But one drawing on the board would be OK, although not necessary
After you have spoken, I will ask one or two questions
And I may jump in with a comment in the middle if you are not following the structure discussed on the previous slide
I will then prompt the class to ask questions
Usability Engineering - Lecture 1 15

16. Course Assignments & Projects
Each student will have to prepare 3-4 course assignments and submit 2 course projects
Assignments are announced in specific dates (TBA)
Due date: a week from announcement date
Project themes will be announced in time
First Project is a single student project
Second Project is a team project (4 students / team)
Grades may differ according to each student’s proved contribution to the project
Strict deadlines apply for the projects.
First project deadline: Mid-semester (exact date to be announced)
Second project deadline: Last class day of the semester
Assignments and Projects are prepared and submitted in English
