General rules
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 2 | |
| Purpose, description: | A complex, written way of evaluating the subject and knowledge, ability type competence elements in the form of a dissertation. The dissertation basically focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution solution, ie practical (calculation) tasks must also be solved during performance evaluation. The part of the curriculum on which the assessment is based is determined by the lecturer of the subject in agreement with the supervisors, the available working time is 60-90 minutes. | |
| Mid-term assessment No. 2 | ||
| Type: | diagnostic assessment | |
| Number: | 6 | |
| Purpose, description: | In order to successfully carry out further studies within the subject, it is absolutely necessary to check the existence of knowledge-type competence elements in writing (control dissertation), which takes place during the practical session of the subject; the part of the curriculum on which the level assessment is based is determined by the supervisor; test papers may consist of theoretical questions to be explained, which are lexical knowledge; from test questions, which are the interpretation of each concept and the recognition of the connections between them; and computational tasks that examine problem-solving-solving ability; the available working time is a minimum of 10 and a maximum of 25 minutes. | |
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: | Írásbeli teljesítményértékelés, amelynek során a vizsgázó számot ad a tantárgy tudás, képesség, attitűd, valamint önállóság és felelősség típusú kompetenciaelemeinek elsajátításáról, különös tekintettel az anyagszerkezettan, anyagvizsgálat, anyagtulajdonságok témakörében. Az értékelés alapjául szolgáló tananyagrészt a tantárgy előadója határozza meg. A vizsga során rövid, ellenőrző jellegű kérdések ("kiskérdések") és hosszabban megválaszolandó, esszé jellegű kérdések egyaránt lesznek. Az írásbeli vizsga alapján, annak sikeressége esetén elégséges vagy közepes érdemjegy szerezhető, jó vagy jeles vizsgajegy megszerzéséhez szóbeli vizsga is szükséges. | |
| 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: | Oral performance evaluation, during which the candidate gives an account of the acquisition of the knowledge, ability, attitude, as well as independence and responsibility type competence elements of the subject, especially in the field of material structure, material testing, material properties. The part of the curriculum on which the assessment is based is determined by the lecturer of the subject. During the exam, the examiner asks a question from the pre-issued subject matter, the candidate begins to answer the question, and then a professional dialogue develops between the examiner and the candidate. | |

| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
