General rules
Learning outcomes are assessed on the basis of a summative performance measurement with a subject exam that can be completed during the examination period, as well as two partial performance measurements. The examination takes place in the form of a written examination paper and a related oral examination, which requires the necessary lexical knowledge to be taken into account in the performance assessment. The working time available for the written exam paper is 100 minutes. Partial performance assessment (homework): a complex way of evaluating the knowledge, ability, attitude, and independence and responsibility type competence elements of the subject, which takes the form of a group semester homework and a group task.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | The basic aim of partial performance assessment is to examine the existence of learning outcomes belonging to the attitude and autonomy and responsibility competence group. The way to do this is to create a group project task and its documentation. The assignment of tasks must be finalized by the 3rd educational week. The content and form requirements and evaluation principles of the completed task are included in the terms of reference. The task will be completed on the date specified in the academic performance evaluation plan, expected to be in the 14th week of education. A maximum of 20 points can be obtained with the task, a minimum of 40% must be completed. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, point-in-time personal act | |
| Number: | 1 | |
| Purpose, description: | The basic aim of partial performance assessment is to examine the existence of learning outcomes belonging to the attitude and autonomy and responsibility competence group. The way to do this is to present the project task to a professional jury of subject instructors and subject listeners. The content and form requirements and evaluation principles of the task are included in the terms of reference. It will be completed on the date specified in the study performance assessment plan, expected to be in the 14th week of education. A maximum of 20 points can be obtained with the task, a minimum of 40% must be completed. | |
| Mid-term assessment No. 3 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | The basic aim of partial performance assessment is to examine the existence of learning outcomes belonging to the attitude and autonomy and responsibility competence group. The way to do this is to create a measurement and evaluation report that can be prepared in groups. The content and form requirements of the task, the evaluation principles are included in the relevant aids. It will be completed on the date specified in the study performance assessment plan, expected to be in the 14th week of education. A maximum of 10 points can be obtained with the task, a minimum of 40% must be completed. | |
Detailed description of assessments performed during the examination period
Elements of the exam:
| Written partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | The written exam is a complex, written way of assessing the knowledge and ability type competence elements of the subject, which requires the necessary lexical knowledge to be taken into account during the performance assessment. The knowledge material published in lectures, exercises, teaching aids and in a given literature source can be taken into account in the exam. The available working time is 100 minutes. 50 points can be awarded for the written exam, of which a minimum of 40% must be passed. | |
| Oral partial exam | ||
| Obligation: | (partial) exam unit chosen by the student, the exam result assessed by other partial exam unit can be changed unrestrictedly | |
| Description: | The oral exam is a complex, oral way of assessing the knowledge and ability-type competence elements of the subject, which requires the required lexical knowledge to be taken into account in the performance assessment. The knowledge material published in lectures, exercises, teaching aids and in a given literature source may be required for the exam. The examination primarily assesses the interpretation of the relationships and causal relationships between process-level phenomena, as well as the system-wide review of engineering solutions for controlling these phenomena. | |
| 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: | The total score of the completed project task is max. 40 points, which is determined jointly by the score obtained for the written documentation (max. 20 points) and the presentation (max. 20 points). This and the score of the completed report (max. 10 points) are added to the score of the completed written exam (max. 50 points), supplemented by the score obtained for the oral exam. The total subject score calculated in this way (max. 100 points) determines the grade. | |
