It is open to the use of information technology and advanced measurement tools. He is constantly developing the tools he needs to solve problems. It strives for an accurate and error-free solution. It seeks to implement the principles of sustainable development in polymer technology.
Independence and responsibility
He / she independently thinks through the tasks and problems related to polymer technology and solves them based on specific sources. He accepts well-founded critical remarks about his work. In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, well-founded decision based on his analyzes. Collaborates with the instructor and fellow students to expand knowledge.
Teaching methodology
During the lectures we use the method of frontal education. In addition to the lectures, there are laboratory exercises, the performance of which is obligatory and in which we apply a level assessment. Students solve practice-oriented tasks in laboratory sessions both independently and in group work, where they prepare minutes. Communication is written and oral, and the course builds on the use of basic IT tools and techniques.

General rules
At the beginning of the subject's laboratory practice sessions, we hold a level assessment, which is based on laboratory aids that can be downloaded from the subject's website. The condition for obtaining the signature is the completion of more than 40% of all laboratory practice level assessments and the complete completion of laboratory protocols. The course ends with an oral exam, to which the average score of the level assessments takes into account 20%.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | diagnostic assessment | |
| Number: | 5 | |
| Purpose, description: | The purpose of proficiency assessments is to explore students ’prior competencies required to complete laboratory exercises. Level assessment papers are therefore written by students at the beginning of laboratory exercises. The available working time is 10-15 minutes. Only students who have brought the required equipment can take part in the laboratory internships: their own, blank protocol, calculator, ID card. The condition for completing the laboratory exercises is, on the one hand, the successful completion of the test written at the beginning of the laboratory exercises (more than 40%), and, on the other hand, active participation in the laboratory exercises. If the student does not show adequate activity during the lab, he / she can be sent. In this case, the given laboratory practice is considered unsuccessful, regardless of the result of the control assessment, it must be replaced, where the control paper must be rewritten. | |
Detailed description of assessments performed during the examination period
Elements of the exam:
| Written partial exam | ||
| Obligation: | does not apply | |
| Description: | ||
| Oral partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | The list of basic concepts related to the subject will be published by the end of the diligence period. At the beginning of the exam, the student must answer 5 questions in the list briefly. If the student answers at least 4 questions correctly, he / she can proceed to the next part of the exam, otherwise he / she will receive an insufficient grade. Knowledge of basic concepts does not count towards the score. In the next part of the oral exam, the student answers the instructor’s questions orally after a short preparation. The instructor assesses the student's lexical knowledge, as well as how well he / she can make connections between each topic, and how much he / she sees through the connections between each topic. The student must demonstrate adequate knowledge of the main topics (material structure and processing technology) and have the ability to solve problems encountered in engineering practice. Based on these, the instructor determines the result of the oral exam on an 80-point scale. | |
| Practical partial exam | ||
| Obligation: | does not apply | |
| Description: | ||
| Inclusion of mid-term results | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | After completing the laboratory exercises, we take the arithmetic average of the scores of the 5 20-point control papers written during the semester, and the score obtained in this way is included in the result of the exam. In total, a maximum of 20 points can be earned in this way. The result of the exam is determined in 20% on the basis of the points obtained in the laboratory exercises and in 80% on the basis of the performance provided in the exam. | |
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 100 % |
The condition for signing is that the score obtained in the mid-year assessments is at least 41%.
The weight of partial exams in grade
| Type: | Proportion |
|---|---|

Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 86 % - 90 % |

| sufficient (2) | Pass [E] | 41 % - 55 % |
| insufficient (1) | Fail [F] | below 41 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 100% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the repeat period | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected by repeating the practice | ||
