Teaching methodology
The teaching of the subject consists of lectures, practices and laboratory sessions. The lectures basically introduce the students to the information defined by the knowledge competence elements using the technique of frontal education. The slides used during the lectures can be downloaded from the website of the subject. The practical sessions in connection with the lectures help to apply the knowledge and acquire it at the skill level. In the framework of practices, a team of three students solves a design task. The topics of the laboratory sessions are also related to the lectures, during which the students apply the acquired knowledge in practice. Topics of laboratory sessions: computer-aided systematic creation of conceptual models of machine tools, performing of machine tool accuracy measurements, constructing of pneumatic circuits, programming of robots.

General rules
The assessment of learning outcomes consists of a mid-term partial achievement assessment and a final exam. The exam is the written and oral assessment of the knowledge and ability type competence elements of the subject, which assesses the knowledge of the lectures. The written part of the exam is compulsory, the oral part is optional. The partial achievement assessment (homework) is a complex way of assessing the knowledge, ability, attitude, and autonomy and responsibility type competence elements of a subject, the form of which is a homework (project) prepared by a team of at least two and at most four students. To obtain a signature and be eligible for the exam, the student must complete a submitted design assignment corresponding to at least 40% achievement and complete all laboratory sessions.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | The purpose of the partial achievement assessment is to examine the existence of learning outcomes belonging to the attitude and independence and responsibility competence groups. As part of the practice, a team of at least two and a maximum of four students solves a designing task that also requires significant home work. The nature of the tasks is the conceptual design of a metal-cutting machine tool or the system design of a manufacturing cell. The student solves the designing task partly jointly with the members of the team, partly individually, in consultation with the supervisor. The content and form requirements of the designing task are included on the design assignment sheet and in the written methodological description. By default, a maximum of 30 points can be obtained with the design task, but in several cases it is also possible to obtain additional points. The condition for obtaining the signature is a design task with a level of at least 40% (12 points). The score of the design task is included in the exam mark. | |
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 part of the exam is mandatory. The written exam (test) measures the level of learning of students determined by knowledge and ability type competencies. The written exam focuses 80% on the theoretical knowledge and 20% on the application skills acquired during the practices and laboratory sessions. A maximum of 70 points can be obtained in the written exam; the exam result of a student who performs below 40% is insufficient (fail). At 40% and above, the examiner determines the a recommended mark on the basis of the written test and the design assignment. To determine the recommended exam mark, a minimum of 12 points can be obtained from the design task and a minimum of 28 and a maximum of 70 points can be obtained from the written test. | |
| 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 part of the exam is not obligatory. The student can take an oral exam after obtaining the recommended mark in the hope of getting a better result. The oral examination may cover both theoretical knowledge and the application skills acquired during the practices or laboratory sessions. The result of the oral exam can be not only better than the original recommended mark but it may also be worse. The students are given a preparation time for the questions received in the oral exam, during which they can also take notes. | |
| Inclusion of mid-term results | ||
| Obligation: | mandatory (partial) exam unit, but failing the unit does not results in fail (1) exam result | |
| Description: | The exam mark includes the mid-term partial achievement assessment, i.e., the result of the design task. To determine the mark recommended after the written exam, at least 12 points can be obtained from the design task, to which the score obtained in the written test (if the written test was successful) is added. Since the design task can also earn extra points, its value also increases the score that can be obtained 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 40%.
The weight of partial exams in grade
| Type: | Proportion |
|---|---|
| Written partial exam | 70 % |
| Oral partial exam | 70 % |
| Inclusion of mid-term results | 30 % |
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 70 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 55 % - 70 % |
| sufficient (2) | Pass [E] | 40 % - 55 % |
| insufficient (1) | Fail [F] | below 40 % |
The lower limit specified for each grade already belongs to that grade.

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).
| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| yes | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||
| partial assesment(s) in this group can be improved or repeated once up to the end of the repeat period | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the teaching term at pre-arranged appointment | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
