Evaluation and Conditions

Updated 10 Nov 2011!

There will be a midterm and a final exam. During the semester you can earn evaluation points at the practicals (possibly for homeworks) and by participating on the wiki-based collaborative lecture notes. You can earn up to 102 points 107 points:

• practicals: 3 pts every week (6 weeks)
• lecture notes: 3 pts every week (12 weeks)
• midterm: 15 pts
• exam: 30 pts
• bonus assignment: 5 pts

The following grading scale will be used:

• A = 80 pts and more
• B = 71 pts and more
• C = 62 pts and more
• D = 53 pts and more
• E = 44 pts and more
• Fx = less than 44 pts

Assignments

Lecture Notes

There is no coherent study-material for this course. You are advised to take notes. To facilitate this, we have created dedicated lecture-notes pages in the students' wiki where you are all asked to regularly contribute in a collaborative fashion. Your goal is to keep coherent, full-scope, up-to-date lecture notes, covering all material from the lectures. And at least briefly, also the practicals. For your activity you can earn up to 3 pts per week. Visit the lecture notes.

HOWTO Work With Sources

Every year we meet students who need increased guidance when working with sources protected by intellectual property rights such as articles and images found on the Web or in the library. Help your colleagues by collaborativelty creating a guide explaining how to properly work with sources so that authors' right are not violated. Your task is to collaboratively produce this HOWTO on the following wikipage:

• http://wiki.matfyz.sk/HOWTO_Ako_pracovať_so_zdrojmi

Use Slovak language in this document. If you wish, you can also create an english version as a separate wiki page. There is probably a large number of publications and articles on this topic available via the Web. Use these sources (proprely) to learn about this problematics. Before you contribute, don't forget to log in.

The deadline for this assignment is 8 Jan 2012 and you can earn up to 5 additional points with it. After the deadline we will evaluate the 5 best contributors to this assignment. The first will get 5 points, the second will get 4 points, and so on.
