Threads
Ioan:
Threads for more
advanced students,
Zagreb 2004
Klaus:
Threads for 1st
semester students,
HU 2006
Mira: Experiment with a group of better students (fourth semester,
some voluntaries from 3rd year) about Tread presentation:
To present to the students both versions of tread presentations (Klaus,
Ioan)
Collect their opinions, suggestions and maybe critical points (in order to
make further improvements or even better to join and then improve
both presentations)

Questionnaire Results
 I think that we have 2 solutions:
 To show .doc file with all students’ opinions, and
discuss only items with arrows (I put arrows on,
in my opinion, illustrative and characteristic
items)
 To take only illustrative and characteristic items
and include them in this presentation
 What do you think about that?

General Suggestions
Results of additional, informal discussions with more motivated and more
interested students:


Both presentations are good, but not excellent. Klaus’ presentation is basic
and too general and Ioan’s is too complex.
Right solution: combination of both presentations.

Introduction, explanation of basic notions and terms
Good elements of both presentations
Additional elements like dispatchers.
Slides have to be interesting, with a lot of animations and graphics.
In presentation it is necessary to include a lot of examples (basic as well as
more complex), with animation of program execution and output.
Also it is necessary to include real-life examples. For example producerconsumer case study has to be visualized.
It is advanced topic and is not suitable for first-year (NS) students.
Content of presentation has to be enough for learning all necessary thread
concepts – students should not use additional sources (books,
manuals,…). After classes students expect to have necessary knowledge
to be able to write their own programs using threads.
Maybe it is better to include this topic (about threads) into Operating
Systems course!?!?
