Lecture Exercises

The purpose of the lecture exercises is to practice and reflect on the theory content presented at the lectures and in the course literature. There are in total five exercises, each dealing with one of the five knowledge areas presented in the course. The difficulty of the questions correspond of the advanced part of the written exams.

Exercises and Deadlines

Below you can find the deadlines for the lecture exercises.

The entire text must be written by yourself. For information about plagiarism see: https://liu.se/en/article/plagiering-upphovsratt

New exercises for 2021 will be published during the course.

Rules

The following items must be considered when solving the exercises:
  • The deadlines are strict. Each exercise must be submitted before the deadline.
  • The text of the solution must not exceed two A4 pages (font size 12 and one column is recommended). Figures and tables are not included, i.e., a solution with e.g. UML diagrams can contain one page of describing texts and two pages of UML diagrams.
  • The solutions can be given in Swedish or English, but not the mixture of the two.
  • The solutions can be created individually or in groups of two students. If you switch groups members examination will be delayed.
  • Dividing the work between two individuals where one person writes exercise 1 and the other one exercise 2 etc. is strictly forbidden and counted as cheating. Hence, if working in a group, it is a requirement that each exercise is performed in collaboration within the group.
  • It is strictly forbidden to copy-and-paste text from other groups or sources. All such cheating or plagiarism will be reported to the disciplinary committee.

Submission

Even a fast grading is a time consuming, manual process, so to work smoothly, the following submission rules apply:

  • The heading of the first page of the submitted document must include full names, LiU-id, and personal numbers (personnummer) for all authors of the solution.
  • The report must be submitted as one pdf-file. Note that both diagrams and text must be in the same pdf-file, i.e., you should not send in several separate files.
  • The file shall be named according to the form: coursecode_liuid1_liuid2_leX_anything.pdf. For example: TDDC93_krisa111_jonwa222_le3_testning.pdf
  • File size is limited to 20 MB
  • When you are registered for the course, go to the course room in Lisam. Click "submissions" ("inlämningar") and chose the one that applies to you.
  • If this is the first time you use Lisam for submitting exercises, consult the student manual.
  • This is a "spontaneous group submission"which means that you form pairs freely amongst the students. If you form a group of more than two students, the last student(s) in the list will be removed by the teachers.
  • Your submissions will be sent to Ouriginal, which is an automatic plagiarism checker.
  • The grading scale (1-5) is not designed to our grading scale 0-4. Don't bother about that.
  • Any mails from Ouriginal about not having enough text for checking can be ignored.

 

Grading and Results

Each exercise can give between zero and four credits to the exam. Please see the examination page for more details.

The grading scale is not linear:

Credit Interpretation
0 Fail. Large parts of the solution is wrong, has insufficient information, contains contradictions, or have non-understandable language
1 Pass. The solution is half-way through. For instance, only half of the tasks are correctly solved. Another alternative is that for each task, there are mistakes, but still every task contains a majority of correct answers.
2 Good solution. The solution is basically correct, but with some few mistakes.
3 Very good solution. The solution is correct, but is either not so precise, for instance, describing unnecessary things, or missing details.
4 Excellent solution. The solution is not only correct, but also precise and clear.

As you see the grading scale is not linear, it is much easier to go from 1 to 2 than from 3 to 4. Half-way good solutions are 1.

The result is sent out at latest two weeks after the submission deadline. You will receive a grade and a list of common mistakes amongst all students' solutions. If you made a very rare mistake, you will get an individual notice.

The grading is time-consuming, and the feed-back is thus limited. No completion is possible.
